SimpleAdapter
    使用ArrayAdapter为listview填充数据的步骤：
   1、在布局文件中添加ListView
   2、在代码中初始化这个listview控件
   3、调用listview.setAdapter()填充数据
        //使用适配器为listview填充数据
		//new SimpleAdapter:context 上下文，resourceId 条目布局文件的资源ID，String[] 要显示的列名，int[] 指定列显示在item布局文件的哪个控件上
		lv.setAdapter(new SimpleAdapter(this, data, R.layout.item,  new String[]{"id","name"}, new int[]{R.id.tv_id,R.id.tv_name}));
关联：条目的布局文件(这种简单的适配器只适用于这种布局)

		gv_home.setOnItemClickListener(new OnItemClickListener() {
			//点击item时调用这个方法
			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				switch (position) {
				case 0://手机防盗
					//检查之前是否设置了密码,如果设置了就弹出输入密码的对话框,
					String password = sp.getString("password", "");
					if(TextUtils.isEmpty(password)){
						//显示设置密码的对话框
						showSetupPasswordDialog();
					}else{
						//显示输入密码的对话框
						showEnterPasswordDialog();
					}
					
					break;
					
				case 8://设置中心
					intent = new Intent(HomeActivity.this,SettingsActivity.class);
					startActivity(intent);
					break;
				default:
					break;
				}
				
				
			}
			
			
		});

	private class MyAdapter extends BaseAdapter{
		@Override//注：九宫格的数目
		public int getCount() {
			return names.length;
		}
		@Override//注：每有一个条目（item）在屏幕上显示都会调用该方法
		public View getView(int position, View convertView, ViewGroup parent) {
			View view;
			if(convertView == null){
				view = View.inflate(HomeActivity.this, R.layout.gv_home_item, null);
			}else{
				view = convertView;
			}
			
			ImageView iv_icon = (ImageView) view.findViewById(R.id.iv_icon);
			TextView tv_name = (TextView) view.findViewById(R.id.tv_name);
			iv_icon.setImageResource(ids[position]);
			tv_name.setText(names[position]);
			return view;
		}
		
		@Override//注：得到指定位置的item
		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return null;
		}
		@Override//得到指定位置item的id值
		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return 0;
		}
