如何实现android视频播放器的全屏显示

我已经实现了android视频播放器，但我不需要像这样，我需要的意思是，当我打开活动时，我需要在中间支付视频半屏幕，当我单击按钮全屏按钮时，我不需要全屏支付，如何实现它帮助我

视频播放活动

public class VideoPlayerActivity extends Activity implements SurfaceHolder.Callback, MediaPlayer.OnPreparedListener, VideoControllerView.MediaPlayerControl {

    SurfaceView videoSurface;
    MediaPlayer player;
    VideoControllerView controller;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video_player);

        videoSurface = (SurfaceView) findViewById(R.id.videoSurface);
        SurfaceHolder videoHolder = videoSurface.getHolder();
        videoHolder.addCallback(this);

        player = new MediaPlayer();
        controller = new VideoControllerView(this);

        try {
            player.setAudioStreamType(AudioManager.STREAM_MUSIC);
            player.setDataSource(this, Uri.parse("http:/myipadree/sites/default/files/759226_639541239394676_1125470178_n.mp4"));
            player.setOnPreparedListener(this);
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (SecurityException e) {
            e.printStackTrace();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        controller.show();
        return false;
    }

    // Implement SurfaceHolder.Callback
    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {

    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        player.setDisplay(holder);
        player.prepareAsync();
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {

    }
    // End SurfaceHolder.Callback

    // Implement MediaPlayer.OnPreparedListener
    @Override
    public void onPrepared(MediaPlayer mp) {
        controller.setMediaPlayer(this);
        controller.setAnchorView((FrameLayout) findViewById(R.id.videoSurfaceContainer));
        player.start();
    }
    // End MediaPlayer.OnPreparedListener

    // Implement VideoMediaController.MediaPlayerControl
    @Override
    public boolean canPause() {
        return true;
    }

    @Override
    public boolean canSeekBackward() {
        return true;
    }

    @Override
    public boolean canSeekForward() {
        return true;
    }

    @Override
    public int getBufferPercentage() {
        return 0;
    }

    @Override
    public int getCurrentPosition() {
        return player.getCurrentPosition();
    }

    @Override
    public int getDuration() {
        return player.getDuration();
    }

    @Override
    public boolean isPlaying() {
        return player.isPlaying();
    }

    @Override
    public void pause() {
        player.pause();
    }

    @Override
    public void seekTo(int i) {
        player.seekTo(i);
    }

    @Override
    public void start() {
        player.start();
    }

    @Override
    public boolean isFullScreen() {
        return false;
    }

    @Override
    public void toggleFullScreen() {

    }
    // End VideoMediaController.MediaPlayer

这是一个演示自定义媒体控件，但是全屏和小屏幕没有代码。 我正在全屏创建方法setFullScreen。下面的代码为我工作

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;
    }
}

或者为旋转屏幕使用OnConfiguration Changed

*@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);
  }
}

在AndroidManifest.xml中添加代码

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

对不起，英语
