ImageSwitcher使用示例

mainActivity如下:

package c.c;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.AnimationUtils;
import android.widget.ImageSwitcher;
import android.widget.ImageView;
import android.widget.ViewSwitcher.ViewFactory;
public class MainActivity extends Activity {
    private ImageSwitcher mImageSwitcher;
    private int images [];
    private int imageIndex=0;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        init();
    }
   private void init(){
	   images=new int[]{R.drawable.a,R.drawable.b,R.drawable.c,R.drawable.d};
	   mImageSwitcher=(ImageSwitcher) findViewById(R.id.imageSwitcher);
	   //设置用于显示图片的ImageView
	   mImageSwitcher.setFactory(new ViewFactory() {
		public View makeView() {
			ImageView imageView=new ImageView(MainActivity.this);
			return imageView;
		}
	   });
	   //处理点击事件
	   mImageSwitcher.setOnClickListener(new ClickListenerImpl());
	   //设置图片进入和退出动画
	   mImageSwitcher.setInAnimation
	   (AnimationUtils.loadAnimation(MainActivity.this, android.R.anim.slide_in_left));
	   mImageSwitcher.setOutAnimation
	   (AnimationUtils.loadAnimation(MainActivity.this, android.R.anim.slide_in_left));
	   //设置初始时显示的图片
	   mImageSwitcher.setImageResource(images[imageIndex]);
   }

	private class ClickListenerImpl implements OnClickListener {
		public void onClick(View v) {
			imageIndex++;
			if (imageIndex == images.length) {
				imageIndex = 0;
			}
			mImageSwitcher.setImageResource(images[imageIndex]);
		}

	}
}

main.xml如下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

   <ImageSwitcher
       android:id="@+id/imageSwitcher"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_centerInParent="true"
   />

</RelativeLayout>
