推荐答案

刚刚发现这篇文章，同时试图弄清楚如何做同样的事情.以下是我为将来发现此问题的其他人所做的.

Just found this post while trying to figure out how to do the same thing. Here's how I did it for anyone else that finds this in the future.

样式xml如下:

    <?xml version="1.0" encoding="utf-8"?>
    <resources>
        <style name="PauseDialog" parent="@android:style/Theme.Dialog">
            <item name="android:windowTitleStyle">@style/PauseDialogTitle</item>
        </style>

        <style name="PauseDialogTitle" parent="@android:style/TextAppearance.DialogWindowTitle">
            <item name="android:gravity">center_horizontal</item>
        </style>
        <style name="DialogWindowTitle">
        <item name="android:maxLines">1</item>
        <item name="android:scrollHorizontally">true</item>
        <item name="android:textAppearance">@android:style/TextAppearance.DialogWindowTitle</item>
        </style>
    </resources>

在我想要设置样式的对话框的 onCreateDialog 方法的活动中，我创建了这样的对话框:

And in my activities onCreateDialog method for the dialog I want styled I create the dialog like this:

Dialog pauseDialog = new Dialog(this, R.style.PauseDialog);
pauseDialog.setTitle(R.string.pause_menu_label);
pauseDialog.setContentView(R.layout.pause_menu);
