Change button background when clicked

Question

I want a button that it has a background image and when I click that button,the button's background or color change (and we go to another activity.) Tell me how can I make this.

Answer 1

Create an xml file and save it in one of the drawable folders in your project,let bg.xml,set this one as the background of your Button

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

where button_pressed and button_notpressed are the images which you want to show on transition of the clicks and normal view of button

In your activity's xml file,set the background of the button as bg.xml

 <Button
        android:id="@+id/btn"
        android:layout_width="150dp"
        android:layout_height="60dp"
        android:textSize="20dp"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="450dp"
        android:background="@drawable/bg"  <--! set it like this-->
        android:text="Submit"
        android:textColor="#FFFFFF" />
