    copied!<p>I have a simple demo with two buttons. They are laid out with a RelativeLayout at the top and bottom of the screen.<br> When I click one of them, I want them to switch places. What is the best way to do that?</p> <p>This is my res/layout/main.xml :</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;ImageButton android:id="@+id/android_button_1" android:layout_width="200dip" android:layout_height="wrap_content" android:src="@drawable/icon" android:layout_alignParentTop="true" /&gt; &lt;ImageButton android:id="@+id/android_button_2" android:layout_width="200dip" android:layout_height="wrap_content" android:src="@drawable/icon2" android:layout_alignParentBottom="true" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>And this is my Activity:</p> <pre><code>public class HelloButtons extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final ImageButton button1 = (ImageButton) findViewById(R.id.android_button_1); final ImageButton button2 = (ImageButton) findViewById(R.id.android_button_2); 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(); } }); } } </code></pre>
