Android viewpager under RelativeLayout

Android viewpager under RelativeLayout - java

I am working on ViewPager. I wrote code which can create ViewPager and also I have some java class, but I want my ViewPager must be below the layout.
This is a my xml code
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#fa6a6a"
>
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#171717" >
<ImageButton
android:id="#+id/menu_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="12dp"
android:background="#drawable/ic_launcher" />
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="7.0mm"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="#drawable/ic_launcher" />
<ToggleButton
android:id="#+id/button_search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="12dp"
android:background="#drawable/ic_launcher"
android:padding="2dip"
android:textOff=""
android:textOn="" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_below="#+id/relativeLayout1" >
<android.support.v4.view.ViewPager
android:id="#+id/vp_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/relativeLayout1" >
</android.support.v4.view.ViewPager>
</RelativeLayout>
This is a my java code:
public class MainActivity extends FragmentActivity implements
ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "test1", "test2", "test3", "test4",
"test5" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager) findViewById(R.id.vp_main);
actionBar = getActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
result it like this
I want my viewpager(actionBar)should be rendered below the layout

Android : Adding space in between tab layout

I am working on an Android project in which I am using TabLayout to show tabs as shown in the image below. As you can see in the screenshot, the tabs are all aligned on the left side. How can I add spaces properly so the three tabs fill out the entire width instead of getting clubbed in on left side. Thank you.

Thank you.

Please remove below line in your activity file
tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
and Change your tablayout
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginTop="0dp"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:tabMode="fixed"
app:tabGravity="fill"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fillViewport="false" />

for (int a= 0; a< tabLayout.getTabCount(); a++) {
View tabView = LayoutInflater.from(context)
.inflate(LayoutInflater.from(this), R.layout.item_main_tabview, null, false);
tabView.setLayoutParams(new TableLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
tabView.setPadding(0, 0, 0, 0);
tabLayout.getTabAt(a).setCustomView(tabViewBinding.getRoot());
}
Thus You can add space between tabs in tablayout

Title in the BottomSheet

I have a BottomSheet with a RecyclerView, and I want to add a title there as in the picture below ("Add new record"), I was trying to add TextView before the RecyclerView in the bottom_sheet LinearLayout, but this text doesn't appear on the screen, also I was trying to add an item in the RecyclerView (but I have a feeling that it's not a right approach), so my question is how to add the title to the BottomSheet?
This is the method where I'm adding items to the RecyclerView, which is in the BottomSheet:
private void showBottomSheetDialog() {
if (behavior.getState() == BottomSheetBehavior.STATE_EXPANDED) {
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
mBottomSheetDialog = new BottomSheetDialog(this);
View view = getLayoutInflater().inflate(R.layout.sheet, null);
RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(new ItemAdapter(createItems(), new ItemAdapter.ItemListener() {
#Override
public void onItemClick(Item item) {
if (mBottomSheetDialog != null) {
mBottomSheetDialog.dismiss();
}
}
}));
mBottomSheetDialog.setContentView(view);
mBottomSheetDialog.show();
mBottomSheetDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
mBottomSheetDialog = null;
}
});
}
#Override
protected void onDestroy() {
super.onDestroy();
mAdapterItem.setListener(null);
}
public List<Item> createItems() {
ArrayList<Item> items = new ArrayList<>();
items.add(new Item(R.drawable.camera, "from new shoots"));
items.add(new Item(R.drawable.folder_multiple_image, "from ready images"));
return items;
}

Please help..

There is nothing in your activity layout with android:id="#+id/LinearContainer, and so FragmentManager does not have anywhere to place your DetailsFragment.

ViewPager doesn't show Fragment

I'm trying to implement a Slinding Menu by using Pager Sliding Tab Strip (com.astuetz:pagerslidingtabstrip).
I set up my xml layout of the main screen:
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight=".97">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/logo_b"
android:src="#drawable/logo_b"
android:layout_weight=".05"
android:layout_gravity="right"
android:layout_marginRight="-15dp" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/scrollMe"
android:layout_weight=".95"
android:fillViewport="false">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal">
<com.astuetz.PagerSlidingTabStrip
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="48dip"
app:pstsIndicatorColor="#19B5FE"
app:pstsShouldExpand="true"
app:pstsTextAllCaps="false"
app:pstsIndicatorHeight="1dp"
/>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</ScrollView>
</LinearLayout>
This xml is included into another View, but it handle the View Pager.
To handle the init of ViewPager and PagerSlidingTapStrip i have a FragmentActivity where during onCreate i have:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sliding_menu);
pager = (ViewPager) findViewById(R.id.pager);
CustomPagerAdapteradapter = new CustomPagerAdapter(getSupportFragmentManager());
adapter.setContext(getApplicationContext());
pager.setAdapter(adapter);
tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
tabs.setViewPager(pager);
}
And the adapter is:
public static class CustomPagerAdapteradapter extends FragmentPagerAdapter implements IconTabProvider {
private int[] ICONS = {
R.drawable.icon_menu0,
R.drawable.icon_menu1,
R.drawable.icon_menu2,
R.drawable.icon_menu3,
R.drawable.icon_menu4
};
private static Context CONTEXT;
private Fragment fragment[] = new Fragment[5];
public CustomPagerAdapteradapter (FragmentManager fm) {
super(fm);
for(int i = 0; i < 5; ++i) {
fragment[i] = Profile.newInstance();
}
}
public void setContext(Context c) { CONTEXT = c; }
#Override
public int getCount() {
return ICONS.length;
}
#Override
public Fragment getItem(int position) {
Toast.makeText(CONTEXT, "" + position, Toast.LENGTH_SHORT).show();
switch (position) {
case 0:
return fragment[position];
case 1:
return fragment[position];
case 2:
return fragment[position];
case 3:
return fragment[position];
case 4:
return fragment[position];
case 5:
return fragment[position];
default:
return fragment[position];
}
}
#Override
public int getPageIconResId(int position) {
return ICONS[position];
}
}
The Profile Fragment xml is:

Profile fragment onCreateView just inflate the xml:
return inflater.inflate(R.layout.fragment_profile, container, false);
Even if the code seems to be ok, I never see profile on the View Pager. What's wrong?

Final answer: remove the ScrollView as it is blocking with ViewPager.

Android Studio Change Fragment on Button Click

Basically I have two fragments with two classes for each and one main class and main activity. I want to set one of the fragment as the home screen and when I press a button it shows the other fragment and hides the previous one.
Problems:
My first problem is that the application is not even opening, its saying,"Unfortunately Application stopped working".
Next, when I click on my button both the fragments are merging and the last fragment is not disappearing.
My main class:
public class MainActivity extends ActionBarActivity {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
UpcomingProject Upcoming = new UpcomingProject();
fragmentTransaction.replace(android.R.id.content, Upcoming);
fragmentTransaction.commit();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
#Override
public void onBackPressed() {
}
My Main Activity:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp"
tools:context=".MainActivity">
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/upcomingproject"/>
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/createproject"/>
</LinearLayout>
My Home page fragment xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp"
>
<Button
android:id="#+id/button_create"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end"
android:text="#string/button_create"
android:layout_margin="15sp"
android:background="#drawable/drawable_buttoncreate"
android:clickable="true" />
</LinearLayout>
My home page fragment java class:
public class UpcomingProject extends Fragment implements View.OnClickListener {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView;
rootView = inflater.inflate(R.layout.upcomingproject, container, false);
Button CreateP = (Button)rootView.findViewById(R.id.button_create);
CreateP.setOnClickListener(this);
return rootView;
}
#Override
public void onClick(View v) {
CreateProject Create = new CreateProject();
fragmentTransaction.replace(android.R.id.content, Create);
fragmentTransaction.commit();
}
}
My second fragment, the one I want to switch too on the click of a button:
public class CreateProject extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView;
rootView = inflater.inflate(R.layout.createproject, container, false);
return rootView;
}
}
And the second fragment's xml:

Try to use getSupportFragmentManager() in your Main Activity to replace first fragment. And getChildFragmentManager() when you replace second fragment

This is a very late reply, but I'll give it in case anyone else hits the same issue.
The reason for this problem was that you have explicitly defined the fragment in your xml file. If you want to swap the fragment it's best to define it as a FrameLayout and then swap it in your onCreate method using e.g.
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
FragmentTransaction fts = getSupportFragmentManager().beginTransaction();
fts.add(R.id.content, UpcomingProject.newInstance());
fts.commit();
setContentView(R.layout.activity_main);
}
This is all explained very well and in much more detail in the link in hrskrs's comment above (https://github.com/codepath/android_guides/wiki/Creating-and-Using-Fragments)
