【Android】使用Gallery组件实现循环显示图像

刚刚写完博文http://blog.csdn.net/jueblog/article/details/12209969 之后，就想着能不能让图片循环播放呢？

试验出一个简便易行的方法。

Activity作如下改进：

只需修改第36行即可：

package com.app.adapter;import com.app.test01.R;import android.content.Context;import android.content.res.TypedArray;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.Gallery;import android.widget.ImageView;public class ImageAdapter extends BaseAdapter {    private Context mContext;    public ImageAdapter(Context c) {        mContext = c;    }    public int getCount() { /* 重写方法getCount,传回图片数目总数 */        return Integer.MAX_VALUE;    }    public Object getItem(int position) {/* 重写的getItem,传回position */        return position;    }    public long getItemId(int position) {/*重写方法getItemId,传回position */         return position;    }    public View getView(int position, View convertView, ViewGroup parent) {        ImageView i = new ImageView(mContext);        i.setImageResource(mImageIds[position%mImageIds.length]);/* 设定图片给imageView对象 */          i.setLayoutParams(new Gallery.LayoutParams(150,75));        return i;    }    public Integer[] getmImageIds() {return mImageIds;}public void setmImageIds(Integer[] mImageIds) {this.mImageIds = mImageIds;}private Integer[] mImageIds = {            R.drawable.image01,            R.drawable.image02,            R.drawable.image03,            R.drawable.image04,            R.drawable.image05,            R.drawable.image06,            R.drawable.image07,            R.drawable.image08,            R.drawable.image09,    };}

如你所见，仅需修改21行和34行。从而即可实现Gallery组件的循环播放。
