在Android应用程序中播放youtube视频

Question

大家好。请尝试从youtube频道播放视频。让我来解释一下1:在第一个活动中，你在listview中得到一个用户列表2:当你点击用户，它加载他们的视频在另一个列表视图。到目前为止，一切都很完美，但我不知道如何播放视频，当那个特定的视频被点击时。这是我的代码。

                //JSONArray jsonArray = json.getJSONObject("data").getJSONArray("items");
                JSONArray videosarray = videoObj.getJSONObject("data").getJSONArray("items");;
                for(int i=0; i<videosarray.length();i++){
                    Youtube yvideos = new Youtube();
                    JSONObject video = videosarray.getJSONObject(i);
                    String videourl = video.getJSONObject("player").getString("mobile");
                    yvideos.setVideoTitle(video.getString("title"));
                    yvideos.setThumbs(video.getJSONObject("thumbnail").getString("sqDefault"));
                    //yvideos.setVideourl(videourl);

                    Log.d("Title",video.getString("title"));
                    Log.d("Video",videourl);
                    Log.d("Thumb",video.getJSONObject("thumbnail").getString("sqDefault"));
                }
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            YoutubeAdapter Adapter = new YoutubeAdapter(getApplicationContext(),R.layout.videos,y_list);
            listv.setAdapter(Adapter);
        }
        public void onStart(){
               mprogress = ProgressDialog.show(YoutubeVideos.this, "Connecting...", "Retrieveing Videos");
            }
        public void onFinish(){
            mprogress.dismiss();
        }
         public void onFailure(Throwable error, String content)
            {
             //Log.e("Error", content);
             Toast.makeText(getBaseContext(), "Error Connecting to the internet", Toast.LENGTH_LONG).show();
            }

    });
}

}

Answer 1

你可以使用Google提供的"YouTube Android Player API"来播放YouTube视频。

YouTube Android Player API允许您合并视频回放功能到你的Android应用程序。API定义了加载和播放YouTube视频(和播放列表)的方法自定义和控制视频播放体验。

下面是一个使用YouTube Android Player API的示例应用。

Answer 3

您可以关注YouTube APIhttps://developers.google.com/youtube/android/player/reference/com/google/android/youtube/player/YouTubeIntents或者你可以直接调用intent默认的YouTube播放器:

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube://" + id));
startActivity(intent);

id是url中问号后面的标识符。例如:youtube.com/watch?v=ID

Intent videoIntent = new Intent(Intent.ACTION_VIEW);
videoIntent.setData(url);
videoIntent.setClassName("com.google.anddroid.youtube", "com.google.android.youtube.WatchActivity");
startActivity(videoIntent);
