it is working perfect but it opening full screen if i modify layout file width and height then how to implement full screen and button full screen button

This is demo custom media control, but full screen and small screen no code. http://www.brightec.co.uk/blog/custom-android-media-controller I'm create method setFullScreen. Code below working for me.

private boolean mFullScreen = true;  @Override public boolean isFullScreen() {        if(mFullScreen){             Log.v("FullScreen", "--set icon full screen--");         return false;     }else{         Log.v("FullScreen", "--set icon small full screen--");         return true;     }    } @Override public void toggleFullScreen() {     Log.v("FullScreen", "-----------------click toggleFullScreen-----------");     setFullScreen(isFullScreen());  } // End VideoMediaController.MediaPlayerControl  public void setFullScreen(boolean fullScreen){     fullScreen = false;      if (mFullScreen)      {         Log.v("FullScreen", "-----------Set full screen SCREEN_ORIENTATION_LANDSCAPE------------");          setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);          DisplayMetrics displaymetrics = new DisplayMetrics();           getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);           int height = displaymetrics.heightPixels;           int width = displaymetrics.widthPixels;           android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();           params.width = width;           params.height=height;           params.setMargins(0, 0, 0, 0);           //set icon is full screen          mFullScreen = fullScreen;     }     else{         Log.v("FullScreen", "-----------Set small screen SCREEN_ORIENTATION_PORTRAIT------------");                      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);               DisplayMetrics displaymetrics = new DisplayMetrics();           getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);           final FrameLayout mFrame = (FrameLayout) findViewById(R.id.videoSurfaceContainer);          // int height = displaymetrics.heightPixels;           int height = mFrame.getHeight();//get height Frame Container video           int width = displaymetrics.widthPixels;           android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();           params.width = width;           params.height= height;           params.setMargins(0, 0, 0, 0);           //set icon is small screen           mFullScreen = !fullScreen;     } } 

or use onConfigurationChanged for Rotation screen.

*@Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig);    // Checks the orientation of the screen   if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {     Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();    // setContentView(R.layout.view_lang);       DisplayMetrics displaymetrics = new DisplayMetrics();       getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);       int height = displaymetrics.heightPixels;       int width = displaymetrics.widthPixels;       android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();       params.width = width;       params.height=height;// -80 for android controls       params.setMargins(0, 0, 0, 0);   } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){     Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();     //setContentView(R.layout.view);         DisplayMetrics displaymetrics = new DisplayMetrics();       getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);       int height = displaymetrics.heightPixels;       int width = displaymetrics.widthPixels;       android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();       params.width = width;       params.height=height / 3;       params.setMargins(0, 0, 0, 0);   } } 

add code here in AndroidManifest.xml

 android:configChanges="orientation|keyboard|keyboardHidden|screenSize"  

Sorry English !
