Question

我正在做一个基于视频视图的Android项目。我想在用户点击播放之前显示播放按钮，当用户决定暂停视频时 - 显示暂停按钮。单击暂停按钮应该会从暂停的同一位置（如YouTube视频）再次触发播放视频。

im1.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {

    vv1.setVideoURI(Uri.parse("android.resource://com.example.cm.filmfestival/" + R.raw.mission));
    im1.setVisibility(View.INVISIBLE);
    im2.setVisibility(View.INVISIBLE);
    vv1.start();
  }
});

im2.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {

    vv1.stopPlayback();
    im2.setVisibility(View.VISIBLE);
    im1.setVisibility(View.INVISIBLE);
  }
});

@Override
public boolean onTouch(View v, MotionEvent event) {
    im1.setVisibility(View.VISIBLE);
    vv1.start();
    im2.setVisibility(View.VISIBLE);
    vv1.stopPlayback();

    return true;
}

Answer 1

使用以下代码

       <VideoView
        android:id="@+id/video_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center" />

     public VideoView myVideoView;  
     private int position = 0;  
     private MediaController mediaControls;

   // set the media controller buttons
    if (mediaControls == null)
    {
        mediaControls = new MediaController(MainActivity.this);
    }

    // initialize the VideoView
    myVideoView = (VideoView) findViewById(R.id.video_view);

   try
    {

        // set the media controller in the VideoView
        myVideoView.setMediaController(mediaControls);

        // set the uri of the video to be played
        myVideoView.setVideoURI(Uri.parse("your UrI"));

    } catch (Exception e)
    {
        Log.e("Error", e.getMessage());
        e.printStackTrace();
    }

    myVideoView.requestFocus();

   // we also set an setOnPreparedListener in order to know when the video
    // file is ready for playback

    myVideoView.setOnPreparedListener(new OnPreparedListener()
    {

        public void onPrepared(MediaPlayer mediaPlayer)
        {
            // if we have a position on savedInstanceState, the video
            // playback should start from here
            myVideoView.seekTo(position);

            System.out.println("vidio is ready for playing");

            if (position == 0)
            {
                myVideoView.start();
            } else
            {
                // if we come from a resumed activity, video playback will
                // be paused
                myVideoView.pause();
            }
        }
    });

Answer 2

在VideoView上设置OntouchListener，然后在Ontouch回调中检查视频是否正在播放或暂停，然后再暂停或播放。

...
<form action="{{ url_for('my_blueprint.my_login') }}" method="POST" name="login_user_form">
...

添加以上代码。

然后，添加private boolean stopped = false; private ImageView postVideoPlaypauseIcon; //set it to any play/pause icon postVideoPlaypauseIcon = mView.findViewById(R.id.playpause_icon); private int stopPosition;类，让CustomVideoView扩展它并创建一个对象VideoView并使用video

findviewbyid

使用以下代码

替换VideoView的xml

public class CustomVideoView extends VideoView {
    private PlayPauseListener mListener;

    public CustomVideoView(Context context) {
        super(context);
    }

    public CustomVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomVideoView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public void setPlayPauseListener(PlayPauseListener listener) {
        mListener = listener;
    }

    @Override
    public void pause() {
        super.pause();
        if (mListener != null) {
            mListener.onPause();
        }
    }

    @Override
    public void start() {
        super.start();
        if (mListener != null) {
            mListener.onPlay();
        }
    }

    public static interface PlayPauseListener {
        void onPlay();
        void onPause();
    }

}

最后，添加setOnTouchListener以侦听触摸。

`<package-name.CustomVideoView
                        android:id="@+id/custom_videoview"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        />`

在您的videoView对象上添加video.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if(stopped == false){ stopPosition = postVideo.getCurrentPosition(); video.pause(); stopped = true; } else if(stopped == true){ video.seekTo(stopPosition); video.start(); stopped = false; } Log.e("TAP","from video "); return false; } });
