Moving widgets in runtime on Android

I have a simple demo with two buttons. They are laid out with a RelativeLayout at the top and bottom of the screen.
When I click one of them, I want them to switch places. What is the best way to do that?

This is my res/layout/main.xml :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android=""

        android:layout_alignParentTop="true" />

        android:layout_alignParentBottom="true" />


And this is my Activity:

public class HelloButtons extends Activity {

    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {


        final ImageButton button1 = (ImageButton) findViewById(;
        final ImageButton button2 = (ImageButton) findViewById(;
        button1.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                // Perform action on clicks
                Toast.makeText(HelloButtons.this, "Beep Bop", Toast.LENGTH_SHORT).show();
        button2.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                // Perform action on clicks
                Toast.makeText(HelloButtons.this, "Beep Bop", Toast.LENGTH_SHORT).show();

Answer 1

Use something along these lines

   RelativeLayout.LayoutParams lp1 = (LayoutParams) b1.getLayoutParams();
   RelativeLayout.LayoutParams lp2 = (LayoutParams) b2.getLayoutParams();

   lp2.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
   lp2.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
   lp1.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
   lp1.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 0);


(and the opposite to revert them again) in you OnClickListeners

Answer 2

I would say the best way to do that is not to switch the actual ImageButton locations, but to instead switch the ImageButton images and keep track of the state inside your application so it can react to onClicks correctly.
