Я хочу загрузить YoutubePlayer в фрагмент, используя YouTubePlayerFragment из API
Файл .xml моего фрагмента:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- VIDEO CONTENT -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:paddingLeft="@dimen/layout_horizontal_margin"
android:paddingRight="@dimen/layout_horizontal_margin"
android:paddingTop="@dimen/layout_vertical_margin"
android:paddingBottom="@dimen/layout_vertical_margin" >
<fragment
android:name="com.google.android.youtube.player.YouTubePlayerFragment"
android:id="@+id/youtubeplayer_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
<!-- LYRIC CONTENT -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"

android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="@drawable/af_background"
android:layout_centerInParent="true" />
<!-- TEXT STRUCTURE -->
<LinearLayout
android:orientation="vertical"
android:id="@+id/lyric_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true" >
<LinearLayout
android:id="@+id/start_layout"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center_horizontal"
android:layout_centerInParent="true">
<TextView
android:id="@+id/text_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginTop="@dimen/lyric_margin_top"
android:gravity="center"
android:text="@string/textTitle2"
android:textSize="@dimen/lyric_size"
android:textIsSelectable="false"/>
</LinearLayout>
</LinearLayout>
<!-- FRONT BACKGROUND -->
<ImageView
android:id="@+id/high_part_image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:src="@drawable/af_background_up_side"
android:scaleType="fitStart"/>
<ImageView
android:id="@+id/low_part_image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:src="@drawable/af_background_down_side"
android:scaleType="fitEnd"/>
</RelativeLayout>
</LinearLayout>
Как вы можете видеть, я добавил
Теперь Фрагмент, загружающий этот .xml,:
public class MyFragment extends Fragment{
/**
* The fragment argument representing the item ID that this fragment
* represents.
*/
public static final String ARG_ITEM_ID = "item_id";
/**
* The content this fragment is presenting.
*/
private Items.ItemList mItem;
/**
* Mandatory empty constructor for the fragment manager to instantiate the
* fragment (e.g. upon screen orientation changes).
*/
public MyFragment() {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments().containsKey(ARG_ITEM_ID)) {
// Load the content specified by the fragment
// arguments. In a real-world scenario, use a Loader
// to load content from a content provider.
mItem = Items.ITEM_MAP.get(getArguments().getString(ARG_ITEM_ID));
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(android.R.layout.titles_fragment, container, false);
// Show the content as text in a TextView.
if (mItem != null) {
((TextView) rootView.findViewById(android.R.id.textTitle2)).setMovementMethod(new ScrollingMovementMethod());
}
return rootView;
}
}
Наконец, у меня есть ActivityFragment, который реализует "YouTubePlayer.OnInitializedListener" и из которого я получаю фрагмент.
public class ItemDetailActivity extends FragmentActivity implements YouTubePlayer.OnInitializedListener{
private TextView mTextView;
private ImageView hImageView;
private ImageView lImageView;
public static final String API_KEY = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
public static final String VIDEO_ID = "BJVlU7d-4x0";
private YouTubePlayer youTubePlayer;
private YouTubePlayerFragment youTubePlayerFragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_item_detail);
if (savedInstanceState == null) {
// Create the detail fragment and add it to the activity
// using a fragment transaction.
fragmentTransaction(getIntent().getStringExtra(ItemDetailFragment.ARG_ITEM_ID));
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpTo(this, new Intent(this, ItemListActivity.class));
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
YouTubeInitializationResult result) {
Toast.makeText(this,
"YouTubePlayer.onInitializationFailure(): " + result.toString(),
Toast.LENGTH_LONG).show();
}
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
boolean wasRestored) {
Toast.makeText(getApplicationContext(),
"YouTubePlayer.onInitializationSuccess()",
Toast.LENGTH_LONG).show();
if (!wasRestored) {
player.cueVideo(VIDEO_ID);
}
}
private void fragmentTransaction(String id) {
Bundle arguments = new Bundle();
Fragment fragment;
String content = Items.ITEM_MAP.get(id).content;
if(content.equalsIgnoreCase("Title 1")) {
// Fragment transaction
arguments.putString(ItemDetailFragment.ARG_ITEM_ID, id);
fragment = new ItemDetailFragment();
fragment.setArguments(arguments);
getSupportFragmentManager().beginTransaction()
.replace(R.id.item_detail_container, fragment)
.commit();
}
if(content.equalsIgnoreCase("Title 2")) {
// Fragment transaction
arguments.putString(ItemDetailFragment.ARG_ITEM_ID, id);
fragment = new MyFragment);
fragment.setArguments(arguments);
FragmentManager fm = getSupportFragmentManager();
//youTubePlayerFragment = fragment.getChildFragmentManager().findFragmentById(R.id.youtubeplayer_fragment);
//youTubePlayerFragment = (YouTubePlayerFragment)getFragmentManager().findFragmentById(R.id.youtubeplayer_fragment);
//Fragment ytbfragment = fragment.getChildFragmentManager().findFragmentById(R.id.youtubeplayer_fragment);
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.item_detail_container, fragment);
//ft.add(R.id.youtubeplayer_fragment, youTubePlayerFragment);
ft.commit();
//youTubePlayerFragment.initialize(API_KEY, this);
}
if(content.equalsIgnoreCase("Title 3")) {
// Fragment transaction
arguments.putString(ItemDetailFragment.ARG_ITEM_ID, id);
fragment = new ItemDetailFragment();
fragment.setArguments(arguments);
getSupportFragmentManager().beginTransaction()
.replace(R.id.item_detail_container, fragment)
.commit();
}
}
}
В заголовке 2 я получаю фрагмент и где я пытаюсь получить внутренний фрагмент проигрывателя YouTube с помощью разных методов, но он не работает. Всегда загружайте файл .xml, пытаясь получить плеер, когда я пытаюсь получить YoutubeFragment.
Если я загружаю только оригинальный фрагмент, приложение получает XML файл.
В чем проблема?
