android – YouTubePlayer与AppCompat v7库一起使用

我开发了一款使用YouTube android API在应用内播放特定视频的应用.那时我已经使用了目标API 19,并且还使用了目标API 19.现在我想要使用目标API 22以及使用AppCompat-v7：22库来更改应用程序切换到Material Design的设计.但YouTubeBaseActivity无法打开,应用程序崩溃.下面我将发布到目前为止我所做的事情.

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：

<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

<?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>

所以在开始它不会打开,因为方法getActionBar()返回Null,然后我将其更改为getSupportActionBar()但我不认识它.然后在最后我更改了以下内容：

public class EventDetail extends AppCompatActivity implements
        YouTubePlayer.OnInitializedListener {

它给了我以下错误：

我正在使用Android Studio.任何想法将不胜感激.

解决方法

问题是你正在使用 YouTubePlayerView,这需要你的Activity扩展 YouTubeBaseActivity.然后你改变了你的活动,现在它扩展了AppCompatActivity.这打破了YouTubePlayerView.

解决方案非常简单：使用YouTubePlayerFragment类.这对活动没有任何要求,为您提供了大量的主题选项.
