VideoView videoView;
MediaController mediaController;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        OrientationEventListener orientationEventListener = new OrientationEventListener(this) {
            @Override
            public void onOrientationChanged(int orientation) {
                if (orientation == Configuration.ORIENTATION_PORTRAIT) {

activity_row_click.xml

<?xml version="1.0" encoding="utf-8"?>
<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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/layout"
    tools:context="com.mgb.sdakaraoke.RowClick">

    <VideoView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/video"
        />

</RelativeLayout>

AndroidManifest.xml

 <activity
            android:name=".RowClick"
            android:configChanges="orientation|screenSize">
        </activity>

My goal is when the orientation equals to landscape the action bar must be hide and the videoview must be set to full screen.

please help me on how to achieve that goal.

Here is the screenshot of Lanscape mode that need to be change correctly according to my goal.

Answer 1

add this in your styles.xml

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowTranslucentStatus">true</item>
</style>

apply it to your activity in manifest :

<activity
        android:name=".RowClick"
        android:theme="@style/AppTheme.NoActionBar"
        android:configChanges="orientation|screenSize">
</activity>

this will translucent your status bar too.

you can also try below in your java file code.

@Override
public void onConfigurationChanged(Configuration newConfig) {
 super.onConfigurationChanged(newConfig);
 if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
      getActionBar().hide();
 } else {
      getActionBar().show();
 }
}

or

if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
  getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
  getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
