java - 如何通过YouTube API获取YouTube视频的标题

Question

我有 YouTube 视频的布局。我想设置视频的缩略图和标题。 (我成功设置了缩略图但没有设置标题)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="1.0">

    <com.google.android.youtube.player.YouTubeThumbnailView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginLeft="6dp"
        android:layout_marginTop="10dp"
        android:id="@+id/youtubeThumbnailView"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="YouTube Video"
        android:textSize="20sp"
        android:layout_marginLeft="4dp"
        android:layout_marginTop="10dp"
        android:layout_gravity="center"
        android:id="@+id/textViewTitle"/>
</LinearLayout>

我在这里设置缩略图:

YouTubeThumbnailView youTubeThumbnailView = (YouTubeThumbnailView) newChild.findViewById(R.id.youtubeThumbnailView);
youTubeThumbnailView.initialize(YouTubePlayer.DEVELOPER_KEY, new YouTubeThumbnailView.OnInitializedListener() {
    @Override
    public void onInitializationSuccess(YouTubeThumbnailView youTubeThumbnailView, final YouTubeThumbnailLoader youTubeThumbnailLoader) {   
        youTubeThumbnailLoader.setVideo("FM7MFYoylVs");
        youTubeThumbnailLoader.setOnThumbnailLoadedListener(new YouTubeThumbnailLoader.OnThumbnailLoadedListener() {
             @Override
             public void onThumbnailLoaded(YouTubeThumbnailView youTubeThumbnailView, String s) {
                  youTubeThumbnailLoader.release();
             }

             @Override
             public void onThumbnailError(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader.ErrorReason errorReason) {
             }
        });
    }

    @Override
    public void onInitializationFailure(YouTubeThumbnailView youTubeThumbnailView, YouTubeInitializationResult youTubeInitializationResult) {
    }
});

如何从视频中获取标题？

我在这里看到了一个解决方案:Get title of YouTube video

但我不确定这是否是正确的方法。我想 YouTube API 可以让我们以更简单的方式获取标题，例如:youTubeThumbnailView.getText()。

private void getVideoInfo(){

    // volley
    StringRequest stringRequest = new StringRequest(
            Request.Method.GET,
            "https://www.googleapis.com/youtube/v3/videos?id=" + keyYouTubeVideo + "&key=" +
                    API_KEY +
                    "&part=snippet,contentDetails,statistics,status",
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {

                    try {

                        JSONObject jsonObject = new JSONObject(response);
                        JSONArray jsonArray = jsonObject.getJSONArray("items");

                        JSONObject object = jsonArray.getJSONObject(0);
                        JSONObject snippet = object.getJSONObject("snippet");

                        String title = snippet.getString("title");


                        Log.d("stuff: ", "" + title);


                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Toast.makeText(MainActivity.activity_main, error.getMessage(), Toast.LENGTH_LONG).show();
                }
            }){};

    // Request (if not using Singleton [RequestHandler]
    // RequestQueue requestQueue = Volley.newRequestQueue(this);
    // requestQueue.add(stringRequest);

    // Request with RequestHandler (Singleton: if created)
    RequestHandler.getInstance(MainActivity.activity_main).addToRequestQueue(stringRequest);


}
