推荐答案

您可以使用<一个href="http://developer.android.com/intl/fr/reference/android/$p$pference/Dialog$p$pference.html"><$c$c>Dialog$p$pference并创建自己的布局，你需要输入字段。

You can use a DialogPreference and create your own layout for the input fields you require.

对话preference 是摘要所以你需要创建自己的它的子类，添加的实施<一href="http://developer.android.com/reference/android/$p$pference/Dialog$p$pference.html#onDialogClosed%28boolean%29"><$c$c>onDialogClosed()从对话框，preferences保存价值。

DialogPreference is abstract so you'll need to create your own subclass of it, adding an implementation of onDialogClosed() to save the values from the dialog as Preferences.

您仍然可以通过使用类的XML标记参考自己的类以preferences XML文件。例如：

You can still reference your own class in a Preferences XML file by using the class as the XML tag. For example:

<com.yourdomain.YourDialogPreference
    android:title="Title"
    android:summary="Summary"
    android:key="dialog_preference"/>
