如何解决如何使用youtube播放器API播放频道视频列表中的下一个视频
我已经使用Youtube Data API从YouTube导入了频道列表，并使用Youtube Player API进行了播放。但是，当我应用PlayerStateChange Listener和Playback Event Listener时，它不起作用。
public class VideoPlayActivity extends YouTubeBaseActivity {
YouTubePlayerView youTubePlayerView;
YouTubePlayer.OnInitializedListener onInitializedListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video_play);
Intent i=getIntent();
youTubePlayerView= findViewById(R.id.youtube_player);
final String url = getIntent().getStringExtra("videoId");
youTubePlayerView = findViewById(R.id.youtube_player);
onInitializedListener = new YouTubePlayer.OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider,YouTubePlayer youTubePlayer,boolean b) {
youTubePlayer.loadVideo(url);
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,YouTubeInitializationResult youTubeInitializationResult) {
}
};
youTubePlayerView.initialize("AIzaSyA1_spJ4XGWOCekBLCsSAgWderHHl_46m0",onInitializedListener);
}
private YouTubePlayer.PlaybackEventListener playbackEventListener= new YouTubePlayer.PlaybackEventListener() {
@Override
public void onPlaying() {
}
@Override
public void onPaused() {
}
@Override
public void onStopped() {
}
@Override
public void onBuffering(boolean b) {
}
@Override
public void onSeekTo(int i) {
}
};
YouTubePlayer.PlayerStateChangeListener playerStateChangeListener=new YouTubePlayer.PlayerStateChangeListener() {
@Override
public void onLoading() {
}
@Override
public void onLoaded(String s) {
}
@Override
public void onAdStarted() {
}
@Override
public void onVideoStarted() {
}
@Override
public void onVideoEnded() {
}
@Override
public void onError(YouTubePlayer.ErrorReason errorReason) {
}
};
}
频道vieos的JSON解析如下
private void displayVideos ()
{
RequestQueue requestQueue= Volley.newRequestQueue(this);
StringRequest stringRequest=new StringRequest(Request.Method.GET,url,new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray jsonArray = jsonObject.getJSONArray("items");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject1 = jsonArray.getJSONObject(i);
if (jsonObject1.has("id")){
JSONObject jsonVideoId=jsonObject1.getJSONObject("id");
if (jsonVideoId.has("kind")){
if(jsonVideoId.getString("kind").equals("youtube#video")){
JSONObject jsonObjectSnippet = jsonObject1.getJSONObject("snippet");
JSONObject jsonObjectDefault=jsonObjectSnippet.getJSONObject("thumbnails").getJSONObject("medium");
String video_id=jsonVideoId.getString("videoId");
VideoDetails vd=new VideoDetails();
vd.setVideoId(video_id);
vd.setTitle(jsonObjectSnippet.getString("title"));
vd.setDescription(jsonObjectSnippet.getString("description"));
vd.setUrl(jsonObjectDefault.getString("url"));
videoDetailsoArrayList.add(vd);
}
// recyclerView.setAdapter(adapter);
// adapter.notifyDataSetChanged();
}
}
}
}catch (JSONException e) {
e.printStackTrace();
}
recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
recyclerView.addItemDecoration(new DividerItemDecoration(getApplicationContext(),LinearLayoutManager.VERTICAL));
adapter= new adapter(getApplicationContext(),videoDetailsoArrayList);
recyclerView.setAdapter(adapter);
}
},new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(),error.getMessage(),LENGTH_LONG).show();
}
});
requestQueue.add(stringRequest);
}
}
我希望在youtube播放器启动时像正常youtube播放器一样显示下一个视频按钮或上一个视频按钮。播放器看起来像这样。
