在RecyclerView中播放获取的视频网址

标签： android xml android-recyclerview recycler-adapter

我已经使用RecyclerView来显示我解析的JSON数据列表。它包含视频网址。现在我想在该列表中播放这些视频。所以我的第一个问题是什么是最好的方法（即ExoPlayer） ，MediaPlayer，SurfaceView，TextureView或其他）和第二个问题是如何通过recyclerview适配器实现它。请帮助我。

上下文代码

MainActivity.java

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        recyclerView = (RecyclerView) findViewById(R.id.listView);

        final String url = "My URL";



        new AsyncHttpTask().execute(url);
    }

    public class AsyncHttpTask extends AsyncTask<String, Void, Integer> {

        @Override

            Integer result = 0;
            try {
                URL url = new URL(params[0]);

                urlConnection = (HttpURLConnection) url.openConnection();

                urlConnection.setRequestProperty("Accept", "application/json");

                urlConnection.setRequestMethod("GET");

                int statusCode = urlConnection.getResponseCode();

                if (statusCode==200){
                    inputStream = new BufferedInputStream(urlConnection.getInputStream());

                    String response = convertInputStreamToString(inputStream);

                    parseResult(response);

                    result = 1;
