Question

我一直在寻找解决方案。我为baseAdapter创建了自定义listview。它与图像一起工作正常。在imageView工作之后，我认为VideoView也可以。然后，我看到我必须使用TextureViev代替它，对它进行处理，它的逻辑很明确，但最后，我得到了一些错误，网上没有解决方案。

我尝试使用Glide，它没有用，我又回到了这里。

媒体播放器正在准备我收到这些错误;

E / ExtMediaPlayer-JNI：env-＆gt; IsInstanceOf失败

E / MediaPlayer-JNI：JNIMediaPlayerFactory：bIsQCMediaPlayerPresent 0

准备媒体时;

W / MediaPlayer：info / warning（3,0）

尝试启动时mediaplayer

[12-19 19：32：11.967 378：31124 E /] 不是在avi模式

我需要每一点灵感继续坚持下去，谢谢。

我在baseAdapter课程的内部课程中定义了MainActivity，并实施了mediaplayer和textureview方法;

public  class postAdapter extends BaseAdapter implements TextureView.SurfaceTextureListener, MediaPlayer.OnBufferingUpdateListener, MediaPlayer.OnCompletionListener, MediaPlayer.OnPreparedListener, MediaPlayer.OnVideoSizeChangedListener {
     ArrayList<Posts> posts;
     public postAdapter(ArrayList<Posts> postsToList)
     {
         posts=postsToList;
     }
     MediaPlayer mMediaPlayer;
     TextureView textureView;
     VideoView animatedView;

     @Override
     public int getCount() {
        // Log.d(TAG, "getCount: "+posts.size());
         return posts.size();

     }

     public void addRangeToTop(ArrayList<Posts> newposts)
     {
        for (int i=0;i<newposts.size();i++)
        {
            posts.add(i,newposts.get(i));
        }
     }
     @Override
     public Object getItem(int position) {

         return null;
     }

     @Override
     public long getItemId(int position) {
         return position;
     }

     @Override
     public View getView(int position, View convertView, ViewGroup parent) {

         View child = getLayoutInflater().inflate(R.layout.animatedpost, null);
         TextView titleView = (TextView) child.findViewById(R.id.titleView);
          ImageView imageView = (ImageView) child.findViewById(R.id.capsView);
       animatedView=(VideoView) child.findViewById(R.id.animatedView);
       textureView=(TextureView)child.findViewById(R.id.textureView);
         TextView voteView = (TextView) child.findViewById(R.id.voteView);
        Button button=(Button) child.findViewById(R.id.button2);



        textureView.setSurfaceTextureListener(this);














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


          /* ArrayList<Posts> newp=new ArrayList<Posts>();
                 for (int i=10;i<15;i++)
                 {
                     Posts post=new Posts();
                     post.setPostTitle(i+"dsf");
                     post.setPostVote(i+"sdfsd");
                     newp.add(post);

                 }
                 int index = lv.getFirstVisiblePosition()+newp.size() ;
                 View v2 = lv.getChildAt(0);
                 int top = (v2 == null) ? 0 : v2.getTop();
                 addRangeToTop(newp);
                 notifyDataSetChanged();
                lv.setSelectionFromTop(index, top);*/
                /* Uri uri = Uri.parse("http://somepath"); // missing 'http://' will cause crashed
                 Intent intent = new Intent(Intent.ACTION_VIEW, uri);
                 startActivity(intent);*/

             }
         });
         titleView.setText(posts.get(position).getPostTitle());
         voteView.setText(posts.get(position).getPostVote());
        // imageView.setImageResource(R.drawable.df);



         return child;
     }


     @Override
     public void onBufferingUpdate(MediaPlayer mp, int percent) {

     }

     @Override
     public void onCompletion(MediaPlayer mp) {

     }

     @Override
     public void onPrepared(MediaPlayer mp) {

         Log.d(TAG, "onPrepared: ");

            mp.start();

     }

     @Override
     public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {

     }

     @Override
     public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {
         mMediaPlayer=new MediaPlayer();
         Surface s = new Surface(surface);


         try {

             mMediaPlayer.setDataSource("http://somefunnyvideopath.mp4");
             mMediaPlayer.setSurface(s);


             mMediaPlayer.setOnBufferingUpdateListener(this);

             mMediaPlayer.setOnPreparedListener(this);
             mMediaPlayer. setOnVideoSizeChangedListener( this);



             mMediaPlayer.prepareAsync();

         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     @Override
     public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {

     }

     @Override
     public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
         return false;
     }

     @Override
     public void onSurfaceTextureUpdated(SurfaceTexture surface) {

     }
 }

我会让媒体播放器成为一个单身课程，所以你不必多次对他进行实例化，不确定这是你的问题，但它更好

public class MyMediaPlayer {
    MediaPlayer mp;
    private static volatile MyMediaPlayer instance = null;
    private MyMediaPlayer() { }
    public static MyMediaPlayer getInstance() {
        if (instance == null) {
            synchronized (MyMediaPlayer.class) {
                if (instance == null) {
                    instance = new MyMediaPlayer();}}}
        return instance;
    }}

还可以尝试使用原始资源或图库中的mp4，以便您知道自己的设备可以播放它，以及稍后当它运行时尝试更改为您的链接时，

希望它有所帮助。
