Issue with Android Themes on different Activities

Question

I've got a little App, that should make use of the Systems default theme. However I've got two problems with that:

First thing is, on one Activity (TemplateView) Android does not apply the theme - or its really different from the rest of the app. Second, spinners an buttons on the ConfigurationView are not affected by the theme either.

I do not programmatically touch buttons and stuff. The only thing is the ArrayAdapter of the spinners, which use the andoird.R.layout.simple_spinner_dropdown_item, which should also be themed if I'm not mistaken.

I've been trying to figure out, what is wrong here, but I can't seem to find it.

My Manifest

    <uses-sdk android:minSdkVersion="10"
        android:targetSdkVersion="17" />

    <uses-permission android:name="android.permission.VIBRATE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme" >
        <activity
            android:name="de.isogon.discotalker.viewController.ConfigurationController" android:theme="@android:style/Theme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity><activity android:name="de.isogon.discotalker.viewController.TemplateController"></activity>
        <activity android:name="de.isogon.discotalker.viewController.AboutController"></activity>
        <activity android:name="de.isogon.discotalker.viewController.DisplayController"></activity>

    </application>

Answer 1

问题是，我使用getContext（）方法为第一个视图充气，并使用getApplicationContext（）为另一个视图充气。

Answer 2

使用ArrayAdapter扩展进行ListView时，我遇到了类似的问题-解决方法是使用MyActivity.this上下文，而不是getApplicationContext（）或getContext（）方法。

Answer 3

Had a similar problem related to AppCompat v22.

The activities must extend the AppCompatActivity (instead of Activity) for the AppCompat theme (Material in my case) to be applied to them.
