Android顶用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

java代码如下：

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 girdview = (GridView) this.findViewById(R.id.girdview);		girdview.setAdapter(new ImageAdapter(this));		girdview.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 GirdTemp{			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) {			GirdTemp temp;			if(convertView == null){				convertView = inflater.inflate(R.layout.gridview_item, null);				temp = new GirdTemp();				temp.phone_function_pic = (ImageView) convertView.findViewById(R.id.function_view);				temp.phone_function_name = (TextView) convertView.findViewById(R.id.function_name);				convertView.setTag(holder);			}else{				temp = (GirdHolder) convertView.getTag();			}			temp.phone_function_pic.setImageResource(mFunctionPics[position]);			temp.phone_function_name.setText(mFunctionName[position]);			return convertView;		}			}}

girdview_main.xml代码如下：

1. <?xml version="1.0" encoding="utf-8"?>  
2. <GridView xmlns:android="http://schemas.android.com/apk/res/android"   
3.     android:id="@+id/gridview"  
4.     android:layout_width="fill_parent"   
5.     android:layout_height="fill_parent"  
6.     android:numColumns="auto_fit"  //自动适应多少行
7.     android:verticalSpacing="20dp"  //两行之间的距离
8.     android:horizontalSpacing="20dp"  //两列之间的距离
9.     android:gravity="center"  
10. /> 

 2.跟ListView类似的数据绑定方式
