How to use View Flipper

ViewFlipper is a subclass of android.widget.ViewAnimator, so we can apply Animation on ViewFlipper also. Here is a example; the ViwFlipper change in shifting from one view to another view slowly.So u have to create a folder /res/anim, create two xml file to define the flip-in and flip-out animation.
/res/anim/flipin.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
 android:interpolator="@android:anim/decelerate_interpolator">
<translate
 android:fromXDelta="-100%"
 android:toXDelta="0%"
 android:duration="500" />
</set>

__________________________________________________________________________________

/res/anim/flipout.xml
and also create another xml,the xml name as flipout

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
 android:interpolator="@android:anim/decelerate_interpolator">
<translate
 android:fromXDelta="0%"
 android:toXDelta="100%"
 android:duration="500" />
</set>

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   >
<TextView
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="@string/hello"
   />
<ViewFlipper
 android:id="@+id/viewflipper"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent">

<Button

 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="Flip to second page"/>
</LinearLayout>
<LinearLayout
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"

main code, AndroidViewFlipper.java

package com.sample.AndroidViewFlipper;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ViewFlipper;

public class AndroidViewFlipper extends Activity {

   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
       final ViewFlipper MyViewFlipper = (ViewFlipper)findViewById(R.id.viewflipper);
       Button button1 = (Button)findViewById(R.id.button1);
       Button button2 = (Button)findViewById(R.id.button2);

       Animation animationFlipIn  = AnimationUtils.loadAnimation(this, R.anim.flipin);
       Animation animationFlipOut = AnimationUtils.loadAnimation(this, R.anim.flipout);
       MyViewFlipper.setInAnimation(animationFlipIn);
       MyViewFlipper.setOutAnimation(animationFlipOut);
     
       button1.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub
    MyViewFlipper.showNext();
   }});
     
       button2.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub
    MyViewFlipper.showPrevious();
   }});
   }
}

Dialog List Item

I use a Button click to show a  dialog to select a multiple option using radio buttons.

[sourcecode language="java"]

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class DialogListView extends Activity {
    /** Called when the activity is first created. */

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
        final Button clk=(Button)findViewById(R.id.button1);
        clk.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub


final String items[] = {"5 minutes","15 minutes","30 minutes"};

       AlertDialog.Builder ab=new AlertDialog.Builder(ExampleApp.this);
       ab.setTitle("Title");
       ab.setSingleChoiceItems(items, 0,new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int whichButton) {
       // onClick Action
       
       
       }
       })
       .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int whichButton) {
       // on Ok button action
       
        //ab.setOnItemSelectedListener(arg0);
        //clk.getSelectionStart();
        //clk.setSingleLine();
                 
       }
       })
       .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int whichButton) {
       // on cancel button action
       }
       });
       ab.show();
     
     



}
});
       
        [/sourcecode]

The output will looks like
       
       
    }
}
