如何设置DialogFragment的主题 [英] How to set the theme for DialogFragment

问题描述

有人可以解释一下为什么这种说法效果很好吗?

Can someone please explain why this statement works perfectly well:

setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme_Holo);

而下一条语句不传递

setStyle(DialogFragment.STYLE_NO_TITLE, R.style.dialog);

这是我在样式部门中拥有的东西:

This is what I have in the style's department:

<style
    name="dialog">
    <!-- title encapsulating main part (backgroud) of custom alertdialog -->
    <item
        name="android:windowFrame">@null</item>
        <!-- turn off any drawable used to draw a frame on the window -->
    <item
        name="android:windowBackground">@null</item>
        <!-- turn off any drawable used to draw a frame on the window -->
    <item
        name="android:windowIsFloating">true</item>
        <!-- float the window so it does not fill the screen -->
    <item
        name="android:windowNoTitle">true</item>
        <!-- remove the title bar we make our own-->
    <item
        name="android:windowContentOverlay">@null</item>
        <!-- remove the shadow from under the title bar -->
</style>

推荐答案

尝试将片段的onCreate中的代码用作

Try using the code in onCreate of the fragment as

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
        
    setStyle(DialogFragment.STYLE_NO_TITLE, R.style.dialog);
}
