实际上我是从 json 获取 url，现在在我的列表视图中，它显示了 json 解析中存在的所有 youtube url 列表。单击 url 后，它将转到 youtube 页面并且正在播放该视频，我不想去其他网站从我的应用程序中，视频必须显示在我的应用程序中，因为我将如何使用嵌入到我的应用程序中的 youtube。
如何在我的列表视图中显示 youtube 视频列表，现在它显示 url，我希望它必须显示列表视图的小视频，如果我们单击视频，它将使用嵌入在我的应用程序中播放 youtube 视频
我的活动.java
public class PoojaVideos extends Activity implements FetchDataListener1 {
private ProgressDialog dialog;
ListView lv2;
private List<Application1> items;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_item1);
lv2 =(ListView)findViewById(R.id.listV_main);
lv2.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
Object o = lv2.getItemAtPosition(position);
Application1 obj_itemDetails = (Application1)o;
final Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(((Application1) o).getUrlWiki()));
startActivity(i);
}
});
//praycount.setOnClickListener(this);
initView();
}
private void initView(){
// show progress dialog
dialog = ProgressDialog.show(this, "", "Loading...");
String url = "http://www.ginfy.com/api/v1/videos.json";
FetchDataTask1 task = new FetchDataTask1(this);
task.execute(url);
}
@Override
public void onFetchComplete(List<Application1> data) {
this.items = data;
// dismiss the progress dialog
if ( dialog != null )
dialog.dismiss();
// create new adapter
ApplicationAdapter1 adapter = new ApplicationAdapter1(this, data);
// set the adapter to list
lv2.setAdapter(adapter);
}
@Override
public void onFetchFailure(String msg) {
if ( dialog != null )
dialog.dismiss();
Toast.makeText(this, msg, Toast.LENGTH_LONG).show();
} This is the activity for showing listview and after clicking the item in list it is going to youtube page.
我的布局.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"

<ListView

我不想进入 youtube 网站，视频必须显示在我的应用程序本身中，因为如何使用嵌入

}
这是用于显示布局的行 url
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:descendantFocusability="blocksDescendants">
<TextView
android:id="@+id/prayersLinkWiki"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:autoLink="web"
android:textSize="15sp" />
</RelativeLayout>
在我的列表视图中，它会显示 url，单击 url 后它会转到 youtube 网站观看视频，对于持有者 url 中的列表视图，我们可以使用嵌入此行中的 youtube 视频列表holder.prayersLinkWiki.setText(Html.fromHtml(app1.getUrlWiki()));
