示例1: queryData
import android.widget.SimpleCursorAdapter; //导入方法依赖的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){
tv_clear.setVisibility(VISIBLE);
}
else {
