Android中的GalleryView实例演示-周末福利有美女图

今天周末，祝周末愉快！

先看实例效果：

滑动小图点击后上面的大图就和小图一致了

activity代码：

package com.tmacsky;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.Gallery;
import android.widget.ImageSwitcher;
import android.widget.ImageView;
import android.widget.Toast;
import android.widget.ViewSwitcher.ViewFactory;
public class GalleryActivity extends Activity implements ViewFactory {
	int index = 0;
	ImageSwitcher imageSwitcher;
	int [] image = {R.drawable.ha,R.drawable.hb,R.drawable.hc,R.drawable.hd,R.drawable.he,R.drawable.hf,R.drawable.hg,R.drawable.hh};
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.gallery);
		//设置imageswitch
		imageSwitcher = (ImageSwitcher)findViewById(R.id.imageswitcher);
		//设置一个容器
		imageSwitcher.setFactory(this);
		//给一个初始的值
		imageSwitcher.setImageResource(image[index]);
		//定义gallery
		Gallery gallery = (Gallery)findViewById(R.id.gallery);
		//设置adapter
		gallery.setAdapter(new ImageAdapter());
		gallery.setOnItemClickListener(new OnItemClickListener() {
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				// TODO Auto-generated method stub
				//设置滑动后弹出切换图片的数字
				Toast.makeText(GalleryActivity.this, " " + arg2, 3000).show();
				imageSwitcher.setImageResource(image[arg2]);
			}
		});
	}
	class ImageAdapter extends BaseAdapter{
		public int getCount() {
			// TODO Auto-generated method stub
			return image.length;
		}
		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return image[position];
		}
		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return image[position];
		}
		public View getView(int position, View convertView, ViewGroup parent) {
			// TODO Auto-generated method stub
			ImageView imageView = new ImageView(GalleryActivity.this);
			imageView.setPadding(10, 50, 10, 5);
			imageView.setImageResource(image[position]);
			return imageView;
		}
	}
	//设置工厂的时候，系统需要返回一个新的imageview，此处直接是默认的就可以了
	public View makeView() {
		// TODO Auto-generated method stub
		return new ImageView(this);
	}
}

gallery.xml的文件代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:orientation="vertical"
    >
<ImageSwitcher 
    android:id="@+id/imageswitcher"
    android:background="@drawable/hc"
    android:inAnimation="@android:anim/fade_in"
    android:outAnimation="@android:anim/fade_out"
    android:layout_gravity="center_vertical"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    ></ImageSwitcher>
<Gallery 
    android:layout_width="200px"
    android:layout_height="wrap_content"
    android:id="@+id/gallery"
    android:layout_gravity="center_horizontal"
     >
</Gallery>
</LinearLayout>

那啥图片资源什么的自己可以找自己喜欢的图，OK~
