Question

我知道如何使用 Android youtube API 使用视频 id 获取图像的缩略图，但是如何使用视频标题查找视频的缩略图？

Answer 1

要解析 YouTube 搜索视频 Json Feed，请使用此链接:
https://gdata.youtube.com/feeds/api/videos?v=2&alt=jsonc&q=my+love+by+shovon

这里搜索的是“my love by shovon”。

使用任何 json 解析器解析它并获取搜索项目的 YouTube 视频。使用此 Json 解析器。

public JSONObject getJson()
{
    DefaultHttpClient   httpclient = new DefaultHttpClient(new BasicHttpParams());
    HttpPost httppost = new HttpPost("https://gdata.youtube.com/feeds/api/videos?v=2&alt=jsonc&q=my%20love%20by%20shovon");
    // Depends on your web service
    httppost.setHeader("Content-type", "application/json");

    InputStream inputStream = null;
    String result = null;
    HttpResponse response = null;
    try {
        response = httpclient.execute(httppost);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }           
    HttpEntity entity = response.getEntity();

    try {
        inputStream = entity.getContent();
    } catch (IllegalStateException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    // json is UTF-8 by default i beleive
    BufferedReader reader = null;
    try {
        reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    StringBuilder sb = new StringBuilder();

    String line = null;
    try {
        while ((line = reader.readLine()) != null)
        {
            sb.append(line + "\n");
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    result = sb.toString();
    JSONObject job = null;
    try {
        job = new JSONObject(sb.toString());
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return job;
}
