示例1: queryData

import android.widget.CursorAdapter; //导入依赖的package包/类
/**
 * 关注1
 * 模糊查询数据 & 显示到ListView列表上
 */
private void queryData(String tempName) {

    // 1. 模糊搜索
    Cursor cursor = helper.getReadableDatabase().rawQuery(
            "select id as _id,name from Search where name like '%" + tempName + "%' order by id desc ", null);
    // 2. 创建adapter适配器对象 & 装入模糊搜索的结果
    adapter = new SimpleCursorAdapter(mContext, android.R.layout.simple_list_item_1, cursor, new String[] { "name" },
            new int[] { android.R.id.text1 }, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
    // 3. 设置适配器
    listView.setAdapter(adapter);
    adapter.notifyDataSetChanged();

    System.out.println(cursor.getCount());
    // 当输入框为空 & 数据库中有搜索记录时，显示 "删除搜索记录"按钮
    if (tempName.equals("") && cursor.getCount() != 0){
