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>>）
