Android的Alertbox如何解雇没有任何引用所有打开的Alertbox [英] Android Alertbox How to dismiss all open Alertbox without any references

问题描述

我在游戏中的重新启动选项。但问题是，有可能在现有活动一些开放alertdialog当我preSS重启。

I have a restart option in my game. but the problem is that there may be some open alertdialog in the existing activity when I press restart.

当我preSS重启我想关闭所有打开的Alertdialog（如果有的话）。我没有打通alertdialogs任何引用（可以是0，1个或多个）。

When I press restart I want to dismiss all open Alertdialog(if any). I do not have any reference to opened up alertdialogs(Can be o,1 or more than one).

有没有什么办法可以关闭所有在任何时间活动开辟了alertdialogs无需任何参考​​？

Is there any way I can dismiss all the opened up alertdialogs in the activity at any time without having any reference to it ?

推荐答案

首先，你可以所有的对话分配给一个成员变量，例如

First you could assign all your dialogs to a member variable, e.g.

private Vector<AlertDialog> dialogs = new Vector<AlertDialog>();

@Override
protected Dialog onCreateDialog(int id) {
  switch (id) {
    case DIALOG_ALERT:
      Builder builder = new AlertDialog.Builder(this);
      ...
      AlertDialog dialog = builder.create();
      dialogs.add(dialog);
      dialog.show();
   }
   return super.onCreateDialog(id);
}

之后，您可以测试对话框是否显示或不使用对话框的 isShowing（）办法（检查出从类继承的方法 android.app.Dialog http://developer.android .COM /参考/安卓/应用/ AlertDialog.html ），例如：

Afterwards, you can test whether dialogs are showing or not by using the isShowing() method of your dialogs (check out inherited methods from class android.app.Dialoghttp://developer.android.com/reference/android/app/AlertDialog.html), e.g.

public void closeDialogs() {
   for (AlertDialog dialog : dialogs)
      if (dialog.isShowing()) dialog.dismiss();
}

或者你可以完成并重新启动您的活动为 Pragnani 的说。取决于你在哪里重启按钮...

Or you might finish and start your activity again as Pragnani said. Depends on where your restart button is ...
