Android : change button text and background color

Since API level 21 you can use :

android:backgroundTint="@android:color/white"

you only have to add this in your xml


I think doing this way is much simpler:

button.setBackgroundColor(Color.BLACK);

And you need to import android.graphics.Color; not: import android.R.color;

Or you can just write the 4-byte hex code (not 3-byte) 0xFF000000 where the first byte is setting the alpha.


Here is an example of a drawable that will be white by default, black when pressed:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape>
            <solid
                android:color="#1E669B"/>
            <stroke
                android:width="2dp"
                android:color="#1B5E91"/>
            <corners
                android:radius="6dp"/>
            <padding
                android:bottom="10dp"
                android:left="10dp"
                android:right="10dp"
                android:top="10dp"/>
        </shape>

    </item>
    <item>
        <shape>
            <gradient
                android:angle="270"
                android:endColor="#1E669B"
                android:startColor="#1E669B"/>
            <stroke
                android:width="4dp"
                android:color="#1B5E91"/>
            <corners
                android:radius="7dp"/>
            <padding
                android:bottom="10dp"
                android:left="10dp"
                android:right="10dp"
                android:top="10dp"/>
        </shape>
    </item>
</selector>
