Just so know the listview in the image is fragment generated. But i dont think that should interfere with toolbar's layout. Here is the code for layout -
<RelativeLayout 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/fragment_songlistview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/croctooth"
android:theme="#style/Theme.AppCompat.Light.NoActionBar"
tools:context="com.shaikhsakib.sounddemo.SongActivity">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:background="#color/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:theme="#style/ThemeOverlay.AppCompat.Dark"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
/>
<ListView
android:id="#+id/fragmentSongListView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/toolbar2" />
</RelativeLayout>
And here the the corresponding activity to the above layout -
package com.shaikhsakib.sounddemo;
import android.app.ActionBar;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
public class SongActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_song);
loadFragment();
Toolbar toolbar2 = (Toolbar) findViewById(R.id.toolbar2);
setSupportActionBar(toolbar2);
}
private void loadFragment() {
// create a FragmentManager
FragmentManager fm;
fm = getFragmentManager();
// create a FragmentTransaction to begin the transaction and replace the Fragment
FragmentTransaction fragmentTransaction = fm.beginTransaction();
// replace the FrameLayout with new Fragment
SongListFragment slv = new SongListFragment();
fragmentTransaction.replace(R.id.songFrameLayout, slv);
fragmentTransaction.commit(); // save the changes
}
}
I checked most of the white space toolbar related answers on Stack Overflow but nothing works. Maybe my problem is different.
EDIT 1
Here is my Main Activity. It also loads a fragment listview an ha custom toolbar. But no such whitespace here -
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
loadFragment();
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
private void loadFragment() {
// create a FragmentManager
FragmentManager fm;
fm = getFragmentManager();
// create a FragmentTransaction to begin the transaction and replace the Fragment
FragmentTransaction fragmentTransaction = fm.beginTransaction();
// replace the FrameLayout with new Fragment
PLayListFragment flv = new PLayListFragment();
fragmentTransaction.replace(R.id.frameLayout, flv);
fragmentTransaction.commit(); // save the changes
}
}
Also notice that I am replacing the same R.id.frameLayout in both the activities but that should not have anything to do with toolbar. Can anybody tell why its not happening in MainActivity but in other activity.
The problem was not actually with Toolbar but with Status bar. It needed CoordinatorLayout instead of RelativeLayout as parent. So all i had to do was make the relative layout as child of CoordinatorLayout and pass an attribute like android:fitsSystemWindows="true". That solved the problem.
Here is the solution -
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tools="http://schemas.android.com/tools"
android:fitsSystemWindows="true"
android:background="#color/croctooth"
android:theme="#style/Theme.AppCompat.Light.NoActionBar"
tools:context="com.shaikhsakib.sounddemo.SongActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:background="#color/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
/>
<ListView
android:id="#+id/fragmentSongListView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/toolbar2" />
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

I'm almost new to programming in Android and there are still things that I don't handle very well. Now I'm doing a project in Android using java that has me half frustrated since I've been trying to find and fix a problem for WEEKS but I still can't identify what it is. The app consists of a view that contains a drawer layout with a series of "options", it also contains a viewpager2 and a bottom navigation with 2 other "options." The error appears when I press the bottom navigation tabs since the two fragments they overlap each other, the same happens when I select an option from the navigation drawer, the fragments are superimposed, then I leave you part of my code so that I hope you can help me, thank you very much for taking the time to help me.

I have a Navigation Drawer Activity, however, I'm using a Fragment inside of the drawer. I can't get both data binding and the fragment working together. With the example code the data binding doesn't work. If I change binding = ContentNewSessionBinding.inflate(getLayoutInflater()) to binding = DataBindingUtil.setContentView(this, R.layout.content_new_session_); I get an error that a view cannot be found the fragment.

You should try to move that FrameLayout in your activity_new_session.xml outside the NavigationView, between the toolbar layout and the NavigationView is the place for the fragment container and then you can add to your NavigationView:
app:headerLayout="YourHeaderLayout"
in case you want to have a header in your DrawerLayout
app:menu="YourMenuXml"
where you have the items that will show on your DrawerLayout
I restarted to develop now after years so there were many changes.
Now I'm trying to modify the AppBar (Toolbar), for the activity. (I also see the CoordinatorLayout, but i don't know what differences have with the Linear and Relative).
So in the MainActivity.class i have:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
TextView mTitle = (TextView)
toolbar.findViewById(R.id.toolbar_title);
setSupportActionBar(toolbar);
mTitle.setText(toolbar.getTitle());
getSupportActionBar().setDisplayShowTitleEnabled(false);
mTitle.setTextColor(Color.parseColor("#ff0000"));
and in activity_main.xml:
<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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/title"
android:layout_gravity="center"
android:id="#+id/toolbar_title" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />
</android.support.design.widget.CoordinatorLayout>
And it works fine, the color and the title (or it seems).
Then i also created two other activity (that i open from a button (i will explain one...they made similar problems):
SecondActivity.class:
public class ActivityMappa extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mappa);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbarmappa);
TextView mTitle = (TextView) toolbar.findViewById(R.id.toolbarmappa_title);
setSupportActionBar(toolbar);
mTitle.setText(toolbar.getTitle());
getSupportActionBar().setDisplayShowTitleEnabled(false);
mTitle.setTextColor(Color.parseColor("#ff0000"));
toolbar.setBackgroundColor(Color.parseColor("#fafad2"));
}
and activity_second.xml:
<android.support.constraint.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=".ActivityMappa">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbarmappa"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/title_mappa"
android:layout_gravity="center"
android:id="#+id/toolbarmappa_title" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
</android.support.constraint.ConstraintLayout>
In this second activity, the toolbar color it's right, but the text not change when i run the app (in the android studio preview it was changed), and the text it is in the #string/title_mappa and it exists.
So why the text does not change? The code is the same.
An other thing, when i add stuff in the content_main.xml, the position start under the Toolbar, and if i set the margin/padding, it starts from it, but from the other 2 activity, when i add other stuffs (like imageview), they starts from the app start at the top, above the toolbar, why?
Thank you so much for the help.
Your issue is that you are setting the text of toolbarmappa_title to the title of toolbarmappa but the title of toolbarmappa is null therefore you are setting the text to null. You need to set the text with a predefined string or set the title of toolbarmappa before you get the title.
It would be something like this:
public class ActivityMappa extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mappa);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbarmappa);
TextView mTitle = (TextView) toolbar.findViewById(R.id.toolbarmappa_title);
setSupportActionBar(toolbar);
toolbar.setTitle("insert title here");
mTitle.setText(toolbar.getTitle());
getSupportActionBar().setDisplayShowTitleEnabled(false);
mTitle.setTextColor(Color.parseColor("#ff0000"));
toolbar.setBackgroundColor(Color.parseColor("#fafad2"));
}
Also, general pratice to change the text of a toolbar is not to add a TextView. You can remove the TextView and call toolbar.setTitle("insert text here"); and that eliminates the need of the TextView.
I am trying to make the two tab layout for {profile} and {Child} which should be swipeable too. I have created the layout and fragment for both of them and on Main Activity layout, I have put
<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">
And in my Main Activity.java class my code is
import android.support.v4.view.ViewPager;
import android.os.Bundle;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = {"Profile", "Child"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_edit);
// Initialization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = (ActionBar) getSupportActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
But here in actionBar, I am getting null value, so program execute with null pointer at that point. Due to what reason, null might be coming in getActionBar.
Change your activity theme to #style/Theme.AppCompat or define toolbar in your layout:
<RelativeLayout 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=".MainActivity">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</RelativeLayout>
And set custom action bar:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_edit);
Toolbar toolbar = (Toolbar) findViewById(toolbar);
setSupportActionBar(toolbar);
actionBar = (ActionBar) getSupportActionBar();
}
ActionBar tabs is deprecated and not working since API 21. You should use PagerSlidingTabStrip library.
So I am very new to the Android DK, and was sailing pretty fine until I started trying to mess with Fragments.
At the core of it, what I'm trying to do is have a series of buttons on my app's screen, and whichever button the user presses will change what text/spinners/buttons display on the screen.
How I decided to implement that was via Fragments. I can't figure out why my Fragment isn't displaying however, this should be a relatively simple example.
I had a activity_main.xml that is relatively simple. I've changed variable names, but see below:
<LinearLayout android:id="#+id/mainActivity"
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"
android:orientation="vertical"
android:animateLayoutChanges="true" >
<Button
android:id="#+id/buttonD"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/d_name"
android:onClick="dMenuButton" />
<RelativeLayout
android:id="#+id/fragment_container"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="gone" />
<Button
android:id="#+id/buttonR"
android:layout_below="#id/fragment_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/r_name"
android:onClick="rButton" />
</LinearLayout>
And the corresponding MainActivity.java
public void dMenuButton(View view){
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.show(dFragment);
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.main, menu);
return true;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
dFragment = new DFragment();
fragmentTransaction.add(R.id.fragment_container, dFragment);
fragmentTransaction.commit();
}
}
And the fragment_d.xml
<RelativeLayout 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"
android:orientation="vertical" >
<TextView
android:id="#+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="20dp"
android:text="#string/text1"
android:textAppearance="?android:attr/textAppearanceMedium" />
<Spinner
android:id="#+id/numD"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#id/text1"
android:layout_toRightOf="#id/text1" />
</RelativeLayout>
With its respective DFragment.java
public class DFragment extends Fragment {
static Spinner dSpinner;
ArrayAdapter<CharSequence> dAdapter;
RelativeLayout view;
public static DFragment newInstance() {
DFragment dFragment = new DFragment();
return dFragment ;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = (RelativeLayout) inflater.inflate(R.layout.fragment_d,
container, false);
createSpinners();
return view;
}
private void createSpinners() {
dSpinner = (Spinner) view.findViewById(R.id.numD);
dAdapter= ArrayAdapter.createFromResource(getActivity().getBaseContext(),
R.array.numD,
android.R.layout.simple_spinner_item);
}
}
Currently, the fragment layout is covering up the buttons beneath it. Any help in forcing it to push down the components below would be great.
Thanks in advance.
You are definitely on the right track with the visibility of the fragment_container. You could leave that as visible constantly, then allow the fragment transactions to change what is being displayed in that container.
Depending on your requirements, you could simply perform a .replace(R.layout.fragment_container, anotherFragment) to change which fragment is being displayed (code is pseudo only).
As for the buttons, are you adding them to the activity_main.xml or are they being added in the fragment's layout? As long as you add the new buttons/text after the fragment_container layout in the main activity layout, you should be fine. Let me know exactly what you are trying to achieve with the buttons/text!
Good luck!
