android - YouTubePlayer 与 AppCompat v7 库

Question

我开发了一个应用程序，它使用 YouTube android API 在应用程序内播放某个视频。那时我使用了目标 API 19，也使用了目标 API 19。现在我想改变应用程序的设计切换到 Material Design 使用目标 API 22 并使用 AppCompat- v7 :22+ 库。但是 YouTubeBaseActivity 打不开，应用程序崩溃了。下面我将发布我到目前为止所做的事情。

事件细节.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

...

list 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" />

布局文件:

<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>

所以一开始它没有打开，因为方法getActionBar()返回Null，然后我将其更改为getSupportActionBar()但我不认识它.然后最后我在下面更改了这一行:

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。

Answer 1

问题是您使用的是 YouTubePlayerView , 这需要您的 Activity 来扩展 YouTubeBaseActivity 。然后您更改了您的 Activity，现在它扩展了 AppCompatActivity。这会破坏 YouTubePlayerView。

解决方案非常简单:使用 YouTubePlayerFragment类。这对 Activity 没有任何要求，为您的主题提供了很多选择。
