Question

如何通过文本框中的光标显示检索到的数据..它给出了一个错误 “光标超出界限......”

Cursor c=mydb.rawquery("select * from customer where phone='"+editphone.getText().tostring+" ",null);

editname.settext(c.getString(0));

Answer 1

在c.moveToFirst()之前使用c.getString(0);

Cursor c=mydb.rawquery("select * from customer where phone='"+editphone.getText().tostring+" ",null);
if (c.moveToFirst()){
 editname.settext(c.getString(0));
}
