显示简单信息的对话框 [英] Showing simple message dialogs

问题描述

在我的活动，我想显示简单信息的对话框，这样的东西：

 新AlertDialog.Builder（上下文）.setMessage（消息）.show（）;
 

如果我这样做，对话框会泄漏，当我在旋转的手机（更不用提它会消失一样，所以用户可能会错过它）。我可以使用托管对话，但我不知道如何理智你使用这些类型的短消息？看起来你必须这样做：

 的ShowDialog（SOME_DLG_ID）;
...
@覆盖
onCreateDialog（INT ID）{
    如果（ID == SOME_DLG_ID）{
        新AlertDialog.Builder（上下文）.setMessage（消息）.show（）;
    }
}
 

有没有办法通过什么样的信息应该是到onCreateDialog，因为它的覆盖方法。我讨厌做父母的活动，只是卖场无论当前消息应该是一个成员变量。你怎么都这样做？

感谢

解决方案

  

如果我这样做，对话框会泄漏   当我转动那个电话（不   何况它会消失一样，所以   用户可能会错过它）

您可以添加

 ＆LT;活动
    机器人：configChanges =方向| keyboardHidden
＆GT;
 

你的Andr​​oidManifest.xml中以prevent重新启动该活动的电话旋转时。我使用它在我的应用程序，我的AlertDialog生存的手机的旋转。

In my activity, I'd like to show simple info dialogs, stuff like:

new AlertDialog.Builder(context).setMessage(message).show();

if I do that, the dialog will leak when I rotate that phone (not to mention it will disappear as well, so the user may miss it). I can use the managed dialogs, but I'm not sure how you use it sensibly for these types of short messages? Looks like you have to do this:

showDialog(SOME_DLG_ID);
...
@Override
onCreateDialog(int id) {
    if (id == SOME_DLG_ID) {
        new AlertDialog.Builder(context).setMessage(message).show();
    }
}

there's no way to pass what the message should be into onCreateDialog since its an override method. I'd hate to make a member variable of the parent activity that just stores whatever the current message should be. How do you all do it?

Thanks

解决方案

if I do that, the dialog will leak when I rotate that phone (not to mention it will disappear as well, so the user may miss it)

You can add

<activity 
    android:configChanges="orientation|keyboardHidden"
>

to your AndroidManifest.xml to prevent restarting the activity when the phone rotates. I am using it in my app and my AlertDialog survives the rotation of phone.
