最近一个项目要用到Gallery的效果由于业务的需要，必须要有GridView的功能。

package com.easymorse.grid.demo;import java.util.ArrayList;import java.util.HashMap;import android.app.ListActivity;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.widget.ArrayAdapter;import android.widget.GridView;import android.widget.ListView;import android.widget.SimpleAdapter;public class GridDemoActivity extends ListActivity {/** Called when the activity is first created. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);LayoutInflater layoutInflater = (LayoutInflater) this.getSystemService("layout_inflater");View headerView=layoutInflater.inflate(R.layout.list_header, null);setGridView(headerView);ListView listView=(ListView) this.findViewById(android.R.id.list);listView.addHeaderView(headerView);listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,new String[]{"","","","","",""}));}private void setGridView(View view) {GridView gridView = (GridView) view.findViewById(R.id.grid);gridView.setNumColumns(10);ArrayList<HashMap<String, Object>> items = new ArrayList<HashMap<String, Object>>();for (int i = 0; i < 10; i++) {HashMap<String, Object> map = new HashMap<String, Object>();map.put("ItemImage", R.drawable.k);map.put("ItemText", "" + "(" + i + ")");items.add(map);}SimpleAdapter adapter = new SimpleAdapter(this, items, R.layout.item,new String[] { "ItemImage", "ItemText" }, new int[] {R.id.ItemImage, R.id.ItemText });gridView.setAdapter(adapter);}}
