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>>）
