问题描述
我已经开发了使用 Android版YouTube API 打在应用程序中的某个视频的应用程序。那时我已经作为目标19 API，并且还针对API 19.现在我想要做的使用目标API 22，也是应用程序切换的设计更改为材质设计使用应用程序兼容性-V7：22+库。但 YouTubeBaseActivity 不能被打开，应用程序崩溃。下面我将寄我迄今所做的。
I have developed an app that uses YouTube android API to play a certain video inside the app. At that time I have used as target API 19, and also target API 19. Now I want do change the design of the app switching to Material Design using target API 22 and also using AppCompat-v7 :22+ library. But the YouTubeBaseActivity cant be opened and the application crashes. Below I will post what I have done so far.
EventDetail.java
EventDetail.java
public class EventDetail extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener { .
.
.
protected void onCreate(Bundle savedInstanceState) {
// remove the shadow from action bar
setTheme(R.style.Theme_TranslucentActionBar_ActionBar_NoOverlay);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_event_detail);
// enable back button
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
// setting the action bar initially transparent
mActionBarBackgroundDrawable = new ColorDrawable(
Color.parseColor("#ec5c59"));
mActionBarBackgroundDrawable.setAlpha(0);
getSupportActionBar().setBackgroundDrawable(mActionBarBackgroundDrawable);
// binding the scrollview
...
清单文件
<activity
android:name="com.dev.apk.evente.al.EventDetail"
android:icon="@drawable/ikona_projekte"
android:label="@string/title_activity_event_detail"
android:screenOrientation="portrait"
android:theme="@style/Theme.TranslucentActionBar.ActionBar.Overlay" />
Layut文件：
Layut File:
<RelativeLayout
android:id="@+id/video_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:paddingLeft="23dp"
android:paddingRight="23dp"
android:paddingBottom="15dp"
android:background="@drawable/event_background_block" >
<TextView
android:id="@+id/video_label"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="@color/white"
android:gravity="left"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:text="Video"
android:textColor="@color/VeryDarkGray"
android:textSize="22sp" >
</TextView>
<com.google.android.youtube.player.YouTubePlayerView
android:id="@+id/youtube_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/video_label"
android:background="@color/white" />
</RelativeLayout>
Theme.xml文件
Theme.xml File
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme.TranslucentActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">@style/Widget.ActionBar</item>
</style>
<style name="Theme.TranslucentActionBar.ActionBar" />
<style name="Theme.TranslucentActionBar.ActionBar.Overlay">
<item name="android:actionBarStyle">@style/Widget.ActionBar.Transparent</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="colorPrimary">@color/evente_date_color</item>
<item name="colorPrimaryDark">@color/evente_darken_color</item>
</style>
<!-- Theme without ActionBar shadow (inherits main theme) -->
<style name="Theme.TranslucentActionBar.ActionBar.NoOverlay" parent="Theme.TranslucentActionBar.ActionBar.Overlay">
<item name="android:windowContentOverlay">@null</item>
</style>
</resources>
因此，在开始的时候并没有打开，因为该方法 getActionBar（）返回NULL，然后我把它改为 getSupportActionBar（），但我不承认它。那么，在年底我在下面的改变了这一行：
So at the beginning it doesn't open because the method getActionBar() return Null, then i changed it to getSupportActionBar() but i doesn't recognized it. Then at the end I changed this line in the following:
public class EventDetail extends AppCompatActivity implements
YouTubePlayer.OnInitializedListener {
和它给了我以下错误：

推荐答案
的问题是，你正在使用 YouTubePlayerView ，这需要你的活动延长<一个href=\"https://developers.google.com/youtube/android/player/reference/com/google/android/youtube/player/YouTubeBaseActivity\"相对=nofollow> YouTubeBaseActivity 。然后，你改变的活动，因此，它现在已经扩展 AppCompatActivity 。这打破 YouTubePlayerView 。
The problem is that you're using the YouTubePlayerView, which requires your Activity to extend YouTubeBaseActivity. Then you changed your activity, so that it now extends AppCompatActivity. This breaks YouTubePlayerView.
解决方案是pretty简单：使用 YouTubePlayerFragment 类。这并不构成对活动的任何要求，让你有足够的为您的主题化的选择。
The solution is pretty simple: use the YouTubePlayerFragment class. This does not pose any requirement on the Activity, leaving you with plenty of options for your theming.
