java - ViewVideo上的“播放”按钮

我想知道如何在布局的viewVideo上放置一个播放按钮。另外，我是否必须在布局上放置一些内容才能使其正常工作？

这是我的代码：

public class MainActivity extends AppCompatActivity {

    static final int REQUEST_VIDEO_CAPTURE = 1;
    VideoView resultvideo;

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

        Button click = (Button)findViewById(R.id.videorec);
        resultvideo = (VideoView)findViewById(R.id.videoView);
    }

    public void dispatchTakeVideoIntent(View v) {
        Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
        if (takeVideoIntent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(takeVideoIntent, REQUEST_VIDEO_CAPTURE);
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_VIDEO_CAPTURE && resultCode == RESULT_OK) {
            Uri videoUri = data.getData();
            resultvideo.setVideoURI(videoUri);

            resultvideo.start();

        }
    }
}

最佳答案

使用FrameLayout。

指定一个可在FrameLayout子级中看到的可绘制对象。并使用Foreground Drawable绘制带有可绘制对象的按钮：

myFrameLayout.setForegroundDrawable(myPlayDrawable);
