Question

If i specify the TextView like this, why I am getting a ‘white on white’? I am running
Isn’t TextView on Android is black by default? I am running on Nexus One.

    <TextView
        android:id="@+id/atext"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:singleLine="true"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

Thank you.

My guess is that you are changing the Background of the parent view, but really desire to invert the Theme of the entire Application.

If my assumption is correct, what you want to do it add this line to your AndroidManifest.xml application tag – android:theme="@android:style/Theme.Light".

Eg:

<application android:icon="@drawable/icon"
             android:label="@string/app_name"
             android:theme="@android:style/Theme.Light">
