Example of ImageSwitcher

package com.example.androidimageswitcher;

import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ImageSwitcher;
import android.widget.ImageView;
import android.widget.ViewSwitcher.ViewFactory;

public class MainActivity extends Activity {

Button buttonNext;
ImageSwitcher imageSwitcher;

Animation slide_in_left, slide_out_right;

int imageResources[] = {
android.R.drawable.ic_dialog_alert,
android.R.drawable.ic_dialog_dialer,
android.R.drawable.ic_dialog_email,
android.R.drawable.ic_dialog_info,
android.R.drawable.ic_dialog_map };

int curIndex;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

buttonNext = (Button) findViewById(R.id.next);
imageSwitcher = (ImageSwitcher) findViewById(R.id.imageswitcher);

slide_in_left = AnimationUtils.loadAnimation(this,
android.R.anim.slide_in_left);
slide_out_right = AnimationUtils.loadAnimation(this,
android.R.anim.slide_out_right);

imageSwitcher.setInAnimation(slide_in_left);
imageSwitcher.setOutAnimation(slide_out_right);

imageSwitcher.setFactory(new ViewFactory() {

@Override
public View makeView() {

ImageView imageView = new ImageView(MainActivity.this);
imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);

LayoutParams params = new ImageSwitcher.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

imageView.setLayoutParams(params);
return imageView;

}
});

curIndex = 0;
imageSwitcher.setImageResource(imageResources[curIndex]);

buttonNext.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
if (curIndex == imageResources.length - 1) {
curIndex = 0;
imageSwitcher.setImageResource(imageResources[curIndex]);
} else {
imageSwitcher.setImageResource(imageResources[++curIndex]);
}
}
});
}

}
