Selector for different button states in android

Change button on focus, on-clicked and active mode. Here is a simple and nice code. Add three different buttons of same size in your drawable folder. There is no need to code in your java file.

File : res/drawable/new_button.xml

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

File : res/layout/main.xml


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<Button
android:id="@+id/imageButtonSelector"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/new_button" />

</LinearLayout>
