1.首先创建实现OnItemSelectedListener,ViewFactory类。
2.创建ImageAdapter类。
3.Activity类。
MyOnItemSelectedListener:当Gallery被选择的时候，把被选择的图片放到ImageSwitch里面去。
MyImageAdapter:实现Gallery显示的图片。
ViewFactory:ImageSwitch的显示工厂。
main.xml
MyOnItemSelectedListener.java
-----------------------package com.gallery;import android.app.Activity;import android.os.Bundle;import android.view.animation.AnimationUtils;import android.widget.Gallery;import android.widget.ImageSwitcher;public class MyGalleryActivity extends Activity{private Gallery gallery1;private ImageSwitcher imageswitcher1;private int[] images = new int[] { R.drawable.android0001, R.drawable.android0002, R.drawable.android0003, R.drawable.android0004, R.drawable.android0005, R.drawable.android0006, R.drawable.android0007, R.drawable.android0008 }; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); imageswitcher1 = (ImageSwitcher)findViewById(R.id.imageswitcher1); imageswitcher1.setFactory(new MyViewFactory(MyGalleryActivity.this)); imageswitcher1.setInAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_in)); imageswitcher1.setOutAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_out)); gallery1 = (Gallery)findViewById(R.id.gallery1); gallery1.setAdapter(new MyImageAdapter(this,images)); gallery1.setOnItemSelectedListener(new MyOnItemSelectedListener(imageswitcher1,images)); }}
