单击按钮时如何使 VideoView 全屏显示？

Question

我有一个 VideoView 用于从 url 加载视频。我希望它有一个像 YouTube 一样的状态栏。我使用了 MediaController 但它只有倒带、前进、暂停和恢复。我希望它有一个按钮，单击它可以全屏并退出全屏。 任何我感激的帮助。

Answer 1

为您的视频播放器添加全屏按钮： 1-设置清单

<activity android:name=".YourPlayerActivity"
  android:configChanges="keyboardHidden|orientation|screenSize">

** 这将防止播放器在切换到全屏时重置

2-step 2：在你的 xml 设计中添加一个新的控制器 ** 全屏图像视图

3- 初始化全屏按钮

boolean fullscreen = false;
fullscreenButton = playerView.findViewById(R.id.exo_fullscreen_icon);
fullscreenButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        if(fullscreen) {
            fullscreenButton.setImageDrawable(ContextCompat.getDrawable(MainActivity.this, R.drawable.ic_fullscreen_open));
            getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
            if(getSupportActionBar() != null){
                getSupportActionBar().show();
            }
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) playerView.getLayoutParams();
            params.width = params.MATCH_PARENT;
            params.height = (int) ( 200 * getApplicationContext().getResources().getDisplayMetrics().density);
            playerView.setLayoutParams(params);
            fullscreen = false;
        }else{
            fullscreenButton.setImageDrawable(ContextCompat.getDrawable(MainActivity.this, R.drawable.ic_fullscreen_close));
            getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN
                                                            |View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                                                            |View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
            if(getSupportActionBar() != null){
                getSupportActionBar().hide();
            }
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) playerView.getLayoutParams();
            params.width = params.MATCH_PARENT;
            params.height = params.MATCH_PARENT;
            playerView.setLayoutParams(params);
            fullscreen = true;
        }
    }
});
