GridViewapplist.setOnItemClickListener(clickListener);

 

 

	OnItemClickListener clickListener = new OnItemClickListener() {

		// postition 被点击项的位置
		// view 被电击的view
		// id 被点击项的id
		@Override
		public void onItemClick(AdapterView<?> adapterView, View view,
				int position, long id) {
			// TODO Auto-generated method stub
			//获取被点击的程序相关信息
			ResolveInfo info = mApps.get(position);
			// 该应用的包名
			String pkg = info.activityInfo.packageName;
			// 应用的主activity类
			String cls = info.activityInfo.name;
			ComponentName componet = new ComponentName(pkg, cls);
			Intent i = new Intent();
			i.setComponent(componet);
			startActivity(i);
		}
