android - 在 VideoView 中从暂停状态开始播放视频

Question

对于自定义视频 View ，我必须覆盖 MediaController(以更改按钮的设计并连接到按钮暂停/播放选择器)。情况是这样的:把视频暂停并打开应用程序，然后再次恢复，视频又开始播放了，而且不是从暂停的地方开始播放，于是问题就来了:如何让视频开始播放从那个地方，它被停下来的地方？我需要在 VideoActivity 中更改什么？

public class VideoActivity extends Activity {

    VideoView videoView;

    VkMediaController mc;

    private static final String CURRENT = "duration";

    private static final String URL = "url";

    private Uri mURI;

    private int mCurrentPosition = -1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.video_view_player);
        videoView = (VideoView) findViewById(R.id.videoViewplayer);
        mc = new VkMediaController(this);
        mURI = getIntent().getData();
        if (savedInstanceState != null) {
            mURI = Uri.parse(savedInstanceState.getString(URL));
            mCurrentPosition = savedInstanceState.getInt(CURRENT);

        }
        videoView.setMediaController(mc);
        videoView.setVideoURI(mURI);
        videoView.requestFocus();
    }

    @Override
    protected void onStart() {
        super.onStart();
        videoView.start();
        if (mCurrentPosition != -1) {
            videoView.seekTo(mCurrentPosition);
        }
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        outState.putInt(CURRENT, videoView.getCurrentPosition());
        outState.putString(URL, mURI.toString());
        super.onSaveInstanceState(outState);
    }
}

我认为问题在于当您在 onSaveInstanceState(Bundle outState) 中调用时 videoView.getCurrentPosition() 将始终返回 0，因为那时视频已经重置，所以在 onPause() 时调用 videoView.getCurrentPosition()，这将返回您想要的值。
