九宫格布局

布局activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <GridView
        android:id="@+id/gridView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:numColumns="3" ><!-- 列数  -->
    </GridView>

</RelativeLayout>

MainActivity.java

package com.yqy.yqy_gridviewtest;

import java.util.ArrayList;
import java.util.HashMap;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.GridView;
import android.widget.SimpleAdapter;
import android.widget.Toast;

public class MainActivity extends Activity {

	GridView gridview;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		gridview = (GridView) findViewById(R.id.gridView1);
		initGridView();
	}
	
	private void initGridView() {
		// 生成动态数组，并且转入数据
		ArrayList<HashMap<String, Object>> lstImageItem = new ArrayList<HashMap<String, Object>>();
		for (int i = 0; i < 9; i++) {
			HashMap<String, Object> map = new HashMap<String, Object>();
			map.put("tv", i+1);// 按序号做img
			lstImageItem.add(map);
		}
		SimpleAdapter sa = new SimpleAdapter(this, lstImageItem,
				R.layout.item_gridview, new String[] { "tv" },
				new int[] { R.id.tv });
		gridview.setAdapter(sa);
		gridview.setOnItemClickListener(new ItemClickListener());
	}
	
	class ItemClickListener implements OnItemClickListener {

		@Override
		public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
				long arg3) {
			@SuppressWarnings("unchecked")
			HashMap<String, Object> item = (HashMap<String, Object>) arg0
					.getItemAtPosition(arg2);
			int index = (Integer) item.get("tv");
			Toast.makeText(MainActivity.this, "点击："+index, Toast.LENGTH_SHORT).show();
		}

	}
	

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

}

item_gridview.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="TextView" />

</RelativeLayout>

这就ok了，如果想要图片文字并存，修改item_gridview.xml ok了
