Question

当点击<密码>ListView内的icon时,我试图开辩。方言是,其中载有几个<编码>TextViews,其中显示根据被点击的清单所列信息。每个清单项目在被点击时,将在方言箱内显示不同的信息。

问题在于,如果点击icon,即点叫showDialog(INFO_DIALOG_ENYTY);和方言中的案文只有在CreateDialog内部形成方言时才能更新。

But I want to update TextView s contect which is inside dialog every time i click on List Item icon.

或者如果其他人有另一个选择使用而不是方言,那么,作为我的灵魂,请在把icon点击列入名单时显示信息。

如果案件不是无效,则在点击事件检查时,采用<代码>showdialog(0)方法,将案文打上,显示方言。如果案件没有取消,那么就会产生辩证。
