I have an Android app that has a default theme of Holo.Light but I want to change it to Theme.Black.I tried to do this by changing the style tag in the manifest android:theme="@style/AppTheme"
to Theme.Black but it cannot be found.Is there extra steps I have to take in changing the theme?
To change your application to a different built-in theme, just add this line under application tag in your app's manifest.xml
file.
Example:
<application
android:theme="@android:style/Theme.Holo"/>
<application
android:theme="@android:style/Theme.Holo.Light"/>
<application
android:theme="@android:style/Theme.Black"/>
<application
android:theme="@android:style/Theme.DeviceDefault"/>
If you set style to DeviceDefault it will require min SDK version 14, but if you won't add a style, it will set to the device default anyway.
<uses-sdk
android:minSdkVersion="14"/>
Or try to check your mainActivity.xml you make sure that this one
xmlns:app="http://schemas.android.com/apk/res-auto"here
is included
If you are trying to reference an android style, you need to put "android:" in there
android:theme="@android:style/Theme.Black"
If that doesn't solve it, you may need to edit your question with the full manifest file, so we can see more details
