I am trying to make a welcome activity that has header fragment xml and bottom view fragment xml that contains buttons to login. Can anyone help me how I will put this two fragment xml to my activity_main.xml?
This is my header.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="220dp">
<ImageView
android:id="#android:id/background"
android:layout_width="match_parent"
android:layout_height="220dp"
android:scaleType="centerCrop"
android:src="#drawable/header_bg" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="bottom|right|end"
android:layout_marginStart="#dimen/android_spaces_large"
android:layout_marginEnd="#dimen/android_spaces_large"
android:layout_marginLeft="#dimen/android_spaces_large"
android:layout_marginRight="#dimen/android_spaces_large"
android:layout_marginBottom="#dimen/android_spaces">
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/header_title"
style="#style/Header.TitleText" />
<TextView
android:id="#+id/subtitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/header_subtitle"
style="#style/Header.SubTitleText" />
</LinearLayout>
<View
android:id="#android:id/title"
android:layout_width="wrap_content"
android:layout_height="?android:actionBarSize"
android:background="#layout/header_ab_shadow" />
</FrameLayout>
And my fragment_bottomview.xml that contains only a single button.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button"
android:layout_gravity="center_horizontal" />
</LinearLayout>
And my activity_main.xml looks like this
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.windows81.welcomingwithheader.MainActivity"
tools:ignore="MergeRootFrame" />
I don't know what I am lacking or I am doing wrong, any tutorial link will really help me.
just make two new classes ,lets call them FragmentA and FragmentB and both should extend fragment
than override onCreateView for both fragmentA and fragmentB and set their view to your xml to the header.xml and fragment_bottomview.xml as shown below
public class FragmentA extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle
savedInstanceState) {
View view=inflater.inflate(R.layout.header,container,false);
return view;
}
}
public class FragmentB extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle
savedInstanceState) {
View view;
view=inflater.inflate(R.layout.fragment_bottomview,container,false);
return view;
}
}
and now to add FragmentA and FragmentB into your activity,put this code in your oncreate activity method
FragmentA fragmentA=new FragmentA();
FragmentManager manager=getFragmentManager();
FragmentTransaction trans=manager.beginTransaction();
trans.add(R.id.container,fragmentA,"fragmenta");/*adding fragment into
the
framelayout with id
container*/
FragmentB fragmentB=new FragmentB();
trans.add(R.id.container,fragmentB,"fragmentb");/*adding fragment into
the
framelayout with id
container*/
trans.commit();
and your probably should use relative layout instead of framelayout

I created custom toolbar inside fragment,but i got view like this:
In themes.xml i disabled ActionBar:
<style name="Theme.Project" parent="Theme.MaterialComponents.DayNight.NoActionBar">
This is my custom toolbar layout:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/white"
>
<TextView
android:id="#+id/toolbar_title"
style="#style/TextAppearance.AppCompat.Widget.ActionBar.Title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Home"
android:fontFamily="#font/google_sans"
android:textColor="#color/black"
android:textSize="20sp" />
</androidx.appcompat.widget.Toolbar>
</com.google.android.material.appbar.AppBarLayout>
<include layout="#layout/fragment_home" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
And this is HomeFragment.java:
public class HomeFragment extends Fragment {
private HomeViewModel homeViewModel;
public View onCreateView(#NonNull LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
homeViewModel =
new ViewModelProvider(this).get(HomeViewModel.class);
View root = inflater.inflate(R.layout.toolbar_in_home, container, false);
return root;
}
}
How to remove this white thing on top of screen?
UPD:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.home.HomeFragment">
</androidx.constraintlayout.widget.ConstraintLayout>
This is fragment home(just ConstraintLayout)
UPD2:i also was trying use toolbar in activity_main and it works:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.toolbar);
BottomNavigationView navView = findViewById(R.id.nav_view);
AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
R.id.navigation_home, R.id.navigation_examination, R.id.navigation_profile)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupWithNavController(navView, navController);
}
But i can't do changes if i want to go on other fragment.
I need to set another custom toolbar layout with button like this:
So this is how I did it. My app is based on single activity-multi-fragment model.
I had set activity theme to AppTheme.NoActionBar, so it enabled me to set a custom toolbar.
Later for each fragment I had a separate layout and within which added a custom toolbar like below
<androidx.appcompat.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary">
....
....
</androidx.appcompat.widget.Toolbar>
Within this layout I had added menu items.
If you don't want to follow this, may be you should look at getActionBar().setCustomView(). Keep your activity theme set, so getActionBar() is not null.
You can control action bar layout by calling getActionBar().setCustomView() in fragment onResume() or probably when you are adding or removing a fragment in your activity.
You can use your custom toolbar inside the main layout replace it from com.google.android.material.appbar.AppBarLayout.
Here is an example code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_alignParentTop="true"
android:layout_centerInParent="true"
android:background="#color/colorPrimary">
<ImageView
android:id="#+id/navi"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_alignParentStart="true"
android:layout_centerInParent="true"
android:layout_marginStart="20dp"
android:contentDescription="#string/todo"
android:src="#drawable/navi" />
<ImageView
android:layout_width="180dp"
android:layout_height="?attr/actionBarSize"
android:layout_alignParentTop="true"
android:layout_centerInParent="true"
android:contentDescription="#string/todo"
android:src="#drawable/header2" />
</RelativeLayout>
<include layout="#layout/fragment_home" />
</RelativeLayout>
I added navigation drawer on map activity. Now I'm trying to add a fragment on my home activity, but fragment is not showing in activity, but code in fragment class is working.
Is my FrameLayout hiding behind the map fragment?
I'm very new to fragments.
Please help me.

Toast.makeText(getActivity(), "Ride History", Toast.LENGTH_SHORT).show();
View view = inflater.inflate(R.layout.fragment_ride_history,container,false);

Change layout constraints so that both widgets frame layout and map fragment do not overlap eachother.
for ex:
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
map:layout_constraintBottom_toTopOf="#+id/map"
map:layout_constraintEnd_toEndOf="parent"
map:layout_constraintStart_toStartOf="parent"
map:layout_constraintTop_toTopOf="parent" />
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="434dp"
android:layout_height="297dp"
map:layout_constraintBottom_toBottomOf="parent"
map:layout_constraintEnd_toEndOf="parent"
map:layout_constraintHorizontal_bias="0.0"
map:layout_constraintStart_toStartOf="parent"
tools:context=".HomeActivity" />
I have the following DialogFragment
public class DetailItemFragment extends AppCompatDialogFragment {
#BindView(R.id.task_detail_name)
AppCompatTextView taskDetailNameText;
#BindView(R.id.task_detail_description)
AppCompatTextView taskDetailDescriptionText;
#BindView(R.id.task_detail_priority)
AppCompatTextView taskDetailPriorityText;
#BindView(R.id.toolbar)
Toolbar toolbar;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCanceledOnTouchOutside(true); //doesn't work
dialog.setCancelable(true); //doesn't work
return dialog;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_detail_view, container, false);
ButterKnife.bind(this, view);
//Get the Json back and parse it as a Task
Bundle bundle = getArguments();
final String taskAsJson = bundle.getString("task");
Task task = new Gson().fromJson(taskAsJson, Task.class);
((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);
ActionBar actionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.close);
}
setHasOptionsMenu(false);
taskDetailNameText.setText(task.getName());
taskDetailDescriptionText.setText(task.getDescription());
taskDetailPriorityText.setText(task.getPriority().toString());
return view;
}
I perform the Fragment transaction like so
//Put the clicked item into a Bundle for the next fragment to consume
DialogFragment detailItemFragment = new DetailItemFragment();
Bundle args = new Bundle();
args.putString("task", new Gson().toJson(mTaskListAdapter.getItem(position)));
detailItemFragment.setArguments(args);
getActivity().getSupportFragmentManager().beginTransaction()
.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
.add(R.id.task_detail_fragment_container, detailItemFragment)
.addToBackStack(null)
.commit();
I'm trying to accomplish the following:
* On a tablet/large screen, this displays as a Dialog popup
* On a phone, it will display a fullscreen dialog (pretty much trying to replicate how Google Calendar handles opening event details)
This is what my xlarge/activity_main.xml looks like
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="800dp"
android:layout_height="400dp"

<android.support.design.widget.AppBarLayout

android:layout_width="match_parent"
android:layout_height="wrap_content">

android:id="#+id/toolbar"

android:background="#color/colorPrimary"

</android.support.design.widget.AppBarLayout>
<FrameLayout

app:elevation="#dimen/fab_elevation"
app:fabSize="normal"
app:layout_anchorGravity="bottom|right|end"
app:pressedTranslationZ="#dimen/fab_pressed_elevation" />
</RelativeLayout>
You'll notice I have a FrameLayout that is centered on the screen for loading the DetailItemFragment into. Maybe this isn't the correct way to do this--but I want to bring it up in case that turns out to be the issue.
This is what the fragment_detail_view.xml layout looks like

The issue
When the DialogFragment is open on a tablet, the Activity in the background still accepts touches (i.e. I can interact with the Activity as if the dialog wasn't even present); furthermore, I have no idea how to get the DialogFragment to dismiss when touching outside of it. I've tried the following:
dialog.setCanceledOnTouchOutside(true); (in the onCreateDialog() method)
dialog.setCancelable(true); (in the onCreateDialog() method)
dialog.setCanceledOnTouchOutside(false); (in the onCreateDialog() method)
getDialog().setCanceledOnTouchOutside(true); setCancelable(true); (leads to NullPointerExceptions--performed in onCreateView() for the DialogFragment)
I've gone through all the other questions like this I could find and nothing has worked for me--so clearly I'm doing something wrong.
I appreciate any and all help.
Change to .dialog.setCancelable(false);.
If it's a dialog with OK and Cancel buttons, you can use:
.setCancelable(closeActivity == true ? false : true)
The FrameLayout (task_detail_fragment_container) you are adding your DetailItemFragment TO has a different size then the parent, which means it will not cover the entire layout:
...
android:layout_width="800dp"
android:layout_height="400dp"
...
To fix this, make task_detail_fragment_container the same size as the parent layout (match_parent) and cap the size of the dialog in the dialog layout by introducing another Layout after your container layout:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent"
android:clickable="true"
android:elevation="8dp"
tools:context="io.havoc.todo.view.fragments.DetailItemFragment">
<FrameLayout
andorid:width="800dp"
android:height="400dp"
android:layout_centerInParent="true">
<android.support.design.widget.AppBarLayout ...
//rest of your xlm here
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
Change this
dialog.setCanceledOnTouchOutside(true);
with
dialog.setCanceledOnTouchOutside(false);
I have successfully implemented Google's SlidingTabLayout and it is working as expected but my view is showing a black screen below it. Like so:
Here is the my activity main layout folder:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:elevation= "16dp">
<LinearLayout
android:layout_width="220dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="start"
android:id = "#+id/stickylist">
<ViewFlipper
android:id="#+id/flipper1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:flipInterval="2000"
android:inAnimation="#android:anim/fade_in"
android:outAnimation="#android:anim/fade_out"
>
<ImageView
android:src="#drawable/front"
android:layout_width="220dp"
android:layout_height="180dp"
android:contentDescription="#string/str_img1"
/>
<ImageView
android:src="#drawable/field"
android:layout_width="220dp"
android:layout_height="180dp"
android:contentDescription="#string/str_img2"
/>
<ImageView

android:layout_width="220dp"
android:layout_height="180dp"
android:contentDescription="#string/str_img3"
/>
</ViewFlipper>
<se.emilsjolander.stickylistheaders.StickyListHeadersListView
android:id="#+id/left_drawer"
android:layout_width="220dp"
android:layout_height="fill_parent"
android:layout_gravity="start"

android:dividerHeight="1dp"
android:divider="#drawable/customdrawershape"
/>
</LinearLayout>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="#+id/fragment_container"
android:layout_width="wrap_content"
android:layout_height="fill_parent">
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
Then here is where I implement my PagerAdapter in SlidingTabsBasicFragment:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.tabs, container, false);
....}
tabs.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<xxx.xxx.xxx.SlidingTabLayout
android:id="#+id/pager_header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="16dp"/>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_weight ="1"
android:layout_height="0dp"
>
</android.support.v4.view.ViewPager>
</LinearLayout>
Here is where I call on the fragment in my activity class:
android.support.v4.app.FragmentManager manager = getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.addToBackStack(null);
SlidingTabsBasicFragment fragment = new SlidingTabsBasicFragment();
transaction.replace(R.id.fragment_container, fragment);
transaction.commit();
I do have other simultaneous fragments ongoing from the main activity that should be displayed. Is that what is going on? Here is the code for that fragment using a different layout for both what is displayed as well as the frame layout for the fragment container.
manager = getChildFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.addToBackStack(null);
EventFragment fragment = new EventFragment();
transaction.add(R.id.fragment_container, fragment);
transaction.commit();
The fragment container for the view I am trying to display that is not showing is:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="#+id/fragment_container"
android:layout_width="wrap_content"
android:layout_height="fill_parent">
</FrameLayout>
Here is the layout to the first fragment which uses a custom adapter for each list view tile integrated in from a different layout.
<RelativeLayout
xmlns:ads="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:animateLayoutChanges="true"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:baselineAligned="false"
android:background="#drawable/background">

android:layout_height="wrap_content"

android:indeterminateTint="#42A5F5"
android:indeterminateTintMode="multiply"/>
<com.twotoasters.jazzylistview.JazzyListView

android:divider="#android:color/transparent"
android:dividerHeight="5dp"
android:paddingRight="10dp"
android:paddingLeft="10dp"
android:layout_above="#+id/layout"/>
</RelativeLayout>
EDIT:
Ok now I can get it show the screen by doing the following:
#Override
public Object instantiateItem(ViewGroup container, int position) {
// Inflate a new layout from our resources
switch (position){
case 0:
view = getActivity().getLayoutInflater().inflate(R.layout.eventlistview,
container, false);
new Event();
break;
case 1:
view = getActivity().getLayoutInflater().inflate(R.layout.twitter,
container, false);
new Twitter();
break;
case 2:
view = getActivity().getLayoutInflater().inflate(R.layout.stafflistview,
container, false);
new Staff();
break;
case 3:
view = getActivity().getLayoutInflater().inflate(R.layout.powerschool,
container, false);
new powerschool();
break;
}
// Add the newly created View to the ViewPager
container.addView(view);
// Return the View
return view;
}
But eventually the progress bar for the fragment layout I have code for is supposed to go away and a list view is to be displayed. However, it will just show this layout forever even though there is more going on in the background. Any ideas?
This is so limited if all you can do is a single layout. Seriously? This is bad.
Wild guesses...
in your tabs.xml: your ViewPager has a weight of android:layout_weight ="1" and a height of android:layout_height="0dp" your slidingtablayout has a height of wrap_content and ther father has not weightsum.. Change their father's weightsum to 1 and see..
let me know if it helps
so I know there are a few topics around here that ask about this but none seemed to be the cause of my issue. I have an ActionBarActivity that is going to be switching between a few different fragments, but I'm having a problem getting one of the fragments to show up. The activity does show a fragment when it is first loaded and does that fine. Here is the code that is setting up the initial fragment with the method to switch between fragments that I'm using.
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_container);
final ActionBar actionBar = getSupportActionBar();
actionBar.setTitle("");
if (savedInstanceState == null) navigateTo(START_SCREEN);
}
public void navigateTo(int sectionNumber, Serializable objectParam) {
Fragment fragment = null;
switch (sectionNumber) {
case START_SCREEN:
fragment = createStartScreenFragment(); //returns an instance of the class for this fragment
break;
case SCREEN_TWO:
fragment = createSecondScreenFragment(); //returns an instance of the class for this fragment
break;
}
if (fragment == null) return;
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction trans = fm.beginTransaction();
trans.add(R.id.activity_container, fragment, fragment.getTag());
trans.commit();
trans.show(fragment);
}
activity_containers.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:id="#+id/activity_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
The first fragment that loads successfuly
<GridLayout
android:id="#+id/fragment_start_screen"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.android.Activity">
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
/>
...
</GridLayout>
And here is the fragment xml that isn't showing up
<TextView android:id="#+id/section_label" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fadingEdge="vertical"
android:cacheColorHint="#00000000"
android:fastScrollEnabled="true"
android:padding="2dp">
</ListView>
And here is the misbehaving fragments relevant code:
public class SecondFragment extends Fragment {
public final static int SECTION_NUMBER = 1;
private String mTag = "TAG";
private ParentActivity parentActivity;
public SecondFragment() {
}
public static fragment newInstance() {
SecondFragment fragment = new SecondFragment();
Bundle args = new Bundle();
fragment.setArguments(args);
return fragment;
}
#Override
public void onAttach(final Activity activity) {
super.onAttach(activity);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
parentActivity = (ParentActivity) getActivity();
View rootView = inflater.inflate(R.layout.fragment_second_fragment, container, false);
ListView list = (ListView) rootView.findViewById(R.id.list);
return super.onCreateView(inflater, container, savedInstanceState);
}
}
The biggest problem I'm having here is that there is no error message shown. The text view in the first fragment is supposed to trigger the second fragment to show up on the screen. This used to work when I had that fragment as a DialogFragment and just called .show() on an instance of it. I need it to be a regular fragment now and it doesn't show up. There's no error message that I can see, though debugging it does show it running through all of my code successfully and it looks like its properly inflating the view.
So what could I be missing here that is preventing the fragment from displaying?
Your layout
<TextView android:id="#+id/section_label" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fadingEdge="vertical"
android:cacheColorHint="#00000000"
android:fastScrollEnabled="true"
android:padding="2dp">
</ListView>
Should be within a ViewGroup
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView android:id="#+id/section_label" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fadingEdge="vertical"
android:cacheColorHint="#00000000"
android:fastScrollEnabled="true"
android:padding="2dp">
</ListView>
</LinearLayout>
And you should return rootView in onCreateView().
Also, you might need to use replace method of Fragment Manager to replace one fragment with another, instead of add.
