如何使VideoView全屏

Question

我想使用视频视图在我的活动中播放视频，并在我单击按钮时使其全屏和横向模式（隐藏虚拟按钮和状态栏）。

这是我的活动代码：

public class VideoActivity extends Activity {
private VideoView mVideoView;
private String mUrl;
private Button mFullScreen;
private static String TAG = VideoActivity.class.getName();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d(TAG,"onCreate");
    setContentView(R.layout.video);
    mVideoView = (VideoView) findViewById(R.id.video);
    mFullScreen = (Button) findViewById(R.id.fullscreen);
    File file = new File(Environment.getExternalStorageDirectory(),"video.mp4");
    mVideoView.setVideoPath(file.getPath());
    mVideoView.start();
    mFullScreen.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            enterFullScreen();
            mFullScreen.setVisibility(View.GONE);
        }
    });

}

@Override
protected void onDestroy() {
    super.onDestroy();
    Log.d(TAG,"onDestroy");
}

private void enterFullScreen(){
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);//设置全屏
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//设置横屏
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);//常亮
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
      RelativeLayout.LayoutParams.MATCH_PARENT,
      RelativeLayout.LayoutParams.MATCH_PARENT
    );
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
  }
}

video.xml

 <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <VideoView
        android:id="@+id/video"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:padding="0dp"/>
    <Button
        android:id="@+id/fullscreen"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:visibility="visible"
        android:text="Fullscreen"/>
</RelativeLayout>

您可以将其用于BackButton：

closeButton = (Button) findViewById(R.id.buttonClose);
    closeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            Log.d("VideoPreview", "onClick Close Button");
            VideoFullscreenActivity.super.onBackPressed();
        }
    });

最后，我用Kristo1990和prashantwosti的帮助解决了它。我的代码是：

RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.MATCH_PARENT,
                RelativeLayout.LayoutParams.MATCH_PARENT
        );
private void enterFullScreen(){
        this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//设置横屏
        mVideoView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
        layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
        layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
        layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
        layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
        mVideoView.setLayoutParams(layoutParams);
    }

private void exitFullScreen(){
          this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            mVideoView.setSystemUiVisibility(0);
            isFullScreen = false;
            mFullScreen.setVisibility(View.INVISIBLE);
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
                layoutParams.removeRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
                layoutParams.removeRule(RelativeLayout.ALIGN_PARENT_TOP);
                layoutParams.removeRule(RelativeLayout.ALIGN_PARENT_LEFT);
                layoutParams.removeRule(RelativeLayout.ALIGN_PARENT_RIGHT);
            }else {
                layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM,0);
                layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP,0);
                layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT,0);
                layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT,0);
            }
            mFullScreen.setVisibility(View.VISIBLE);

            mVideoView.setLayoutParams(layoutParams);
        }

在你的横向模式下试试这个。

<VideoView android:id="@+id/video"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
   android:layout_alignParentRight="true"
   android:layout_alignParentBottom="true"
   android:layout_alignParentTop="true"
    />

隐藏虚拟按钮添加此代码：

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

原始尺寸

         DisplayMetrics metrics = new DisplayMetrics();  getWindowManager().getDefaultDisplay().getMetrics(metrics);
         android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
         params.width =  (int) (300*metrics.density);
         params.height = (int) (250*metrics.density);
         params.leftMargin = 30;
         videoView.setLayoutParams(params);

全屏尺寸

         DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics);
         android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
         params.width =  metrics.widthPixels;
         params.height = metrics.heightPixels;
         params.leftMargin = 0;
         videoView.setLayoutParams(params);
