Android中用GridView实现九宫格的两种方法

1.传统办法：实现一个继承BaseAdapter的 ImageAdapter

package com.test;  

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;  

public class GridViewActivity extends Activity {
      //存放各功能图片
    private Integer[] mFunctionPics = {R.drawable.mobilesecurity,R.drawable.infosecurity,
            R.drawable.no_interrupt,R.drawable.bianjiejieting,R.drawable.xiaomishu
            ,R.drawable.sms_send_attime,R.drawable.yule,R.drawable.setting};  
    //存放各功能的名称
    private Integer[] mFunctionName = {R.string.phone_tools_box_name1,
            R.string.phone_tools_box_name2,R.string.phone_tools_box_name3,
            R.string.phone_tools_box_name4,R.string.phone_tools_box_name5,
            R.string.phone_tools_box_name6,R.string.phone_tools_box_name7,
            R.string.phone_tools_box_name8};  
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gridview_main);  

        GridView gridView= (GridView) this.findViewById(R.id.gridView);
        gridView.setAdapter(new ImageAdapter(this));
        gridView.setOnItemClickListener(new OnItemClickListener() {  
            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                Toast.makeText(GridViewActivity.this, "图片ID：" + mFunctionPics[position],1).show();
            }
        });  

    }  

    public class ImageAdapter extends BaseAdapter {
        private Context mContext;
        private LayoutInflater inflater; 

        private class GridHolder {
            ImageView phone_function_pic;
            TextView phone_function_name;
        }
        public ImageAdapter(Context c){
            mContext = c;
            inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }
        @Override
        public int getCount() {
            return mFunctionPics.length;
        }

        @Override
        public Object getItem(int position) {
            return position;
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            GridHolder holder;
            if(convertView == null) {
                convertView = inflater.inflate(R.layout.gridview_item, null);
                holder = new GridHolder();
                holder.phone_function_pic = (ImageView) convertView.findViewById(R.id.function_view);
                holder.phone_function_name = (TextView) convertView.findViewById(R.id.function_name);
                convertView.setTag(holder);
            } else {
                holder = (GridHolder) convertView.getTag();
            }
            holder.phone_function_pic.setImageResource(mFunctionPics[position]);
            holder.phone_function_name.setText(mFunctionName[position]);
            return convertView;
        }  

    }  

}  

2.跟ListView类似的数据绑定方式（SimpleAdapter, ArrayList<Map<String, Object>>）
