为什么我无法将应用程序的主题更改为HOLO.DARK？

Question

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="Zine"
    android:supportsRtl="true"
    android:theme="@style/AppTheme" parent="android:Theme.Holo" >

    <activity android:name=".SplashScreen">
        android:label="@string/Zine" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>









    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
</application>

this is my Androidmanifest.xml

Now this is the app screen:

I have selected the holo dark theme yet I am not getting black color on screen. Instead, I am getting the default theme. How do I fix this?

Do this In your Code.. Working Fine

Also Your Error Reason

The reason you are having this problem is because you are extending the activity with you are trying to apply the dialog theme to is extending AppCompatActivity which requires the AppCompat theme to be applied.

Change the Java inheritance from AppCompatActivity to Activity and leave the dialog theme in the manifest as it is.

Set in Androidmanifest.xml

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="Zine"
android:supportsRtl="true"
android:theme="@style/AppTheme">

<activity android:name=".SplashScreen">
    android:label="@string/Zine" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

<activity android:name=".MainActivity">
    <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.DEFAULT" />
</activity>

In You styles.xml

<!-- Base application theme. -->

<resources>
<style name="AppTheme" parent="android:Theme.Holo">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

</resources>
