Question

I’ve created a custom buttom with a selector:

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@drawable/button_np"
            android:state_enabled="false"/>
        <item android:drawable="@drawable/button_np_pressed"
            android:state_pressed="true"/>
        <item android:drawable="@drawable/button_np"
            android:state_focused="true"/>
        <item android:drawable="@drawable/button_np"/>
    </selector>

I would like to be able to colorize this button by using a gray button as image and then colorize it with a color I’ve defined.

Is that possible?

Thanks

It sure is possible (at least in code), you set a color filter.

import android.graphics.PorterDuff;

Button.getBackground().setColorFilter(0xFF00FF00,PorterDuff.Mode.MULTIPLY);  //  Green
Button.getBackground().setColorFilter(0xFFFF0000,PorterDuff.Mode.MULTIPLY);  // Red

Just choose your colors and put them in the setColorFilter parameters.
