android - 如何在全屏模式下实现android视频播放器

Question

我已经实现了android视频播放器，但我不需要这样我需要的意思是当我打开 Activity 时我需要在中心支付视频半屏当我点击按钮全屏按钮然后我需要全屏支付，如何实现它帮助我....

VideoPlayerActivity

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

它工作完美但是如果我修改布局文件的宽度和高度然后如何实现全屏和按钮全屏按钮它会打开全屏

这是演示自定义媒体控件，但是全屏和小屏没有代码。 http://www.brightec.co.uk/blog/custom-android-media-controller我正在创建方法 setFullScreen。下面的代码对我有用。

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;
    }
}

或将 onConfigurationChanged 用于旋转屏幕。

*@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!
