I'm agree with @sajidkhan answer but @zahra you are doing mistake to set the selector as background wrong. here i will explain @sajidkhan's answer as i know he might be expected here an image.png etc not a selector.xml

 buttonONE.setBackground(R.drawable.round_button_focus);

round_button_focus means round_button_focus.png etc,

in MotionEvent.ACTION_DOWN set one background and when you release the button set another background eg. MotionEvent.ACTION_UP follow @sajidkhan suggestion his answer might deserve as accepted if you think this helped you.

Why you do not use Selctor for ImageView when clicked.

res/drawable/selector.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/your_iamge_pressed"         android:state_pressed="true" />
<item android:drawable="@drawable/your_iamge_pressed"
  android:state_focused="true"
  android:state_enabled="true"
  android:state_window_focused="true"  />
<item android:drawable="@drawable/your_iamge_normal" />

here in you ImageView set the selector as background : android:background="@drawable/selector.xml"

<ImageView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:background="@drawable/selector.xml" />

OR USE TouchListener To implement such idea when you touch(Action Down) set one image as background and when you release (Action Up) set another Image as background.

here is the code

buttonONE.setOnTouchListener(new View.OnTouchListener(){
 @Override
 public boolean onTouch(View v, MotionEvent event) 
   {
   if(event.getAction() == MotionEvent.ACTION_DOWN) {

     buttonONE.setBackground(R.drawable.round_button_focus);


   } else if (event.getAction() == MotionEvent.ACTION_UP) {

     buttonONE.setBackground(R.drawable.round_button_unfocused);
      //  *******start Intent here********
   }
  }
};

Here is the code 

  btnImage =(ImageView) findViewById(R.id.image_button); 
         btnImage.setOnClickListener(new OnClickListener(){

               public void onClick(View arg0) {

               btnImage.setBackgroundResource(R.drawable.ic_launcher);
             //put your image in drawable folder and change ic_luncher by your image.
               Intent i=new Intent(fierst.this,second.class);
               startActivity(i);


               }
           });

Intent i=new Intent(fierst.this,second.class);

startActivity(i);

by executing these two line it will move to second activity so you can't able to see the result for image changed or not. To see the proper output for image change make these lines as comment

Hope this will helpful .thanks
