不能让我的DialogFragment背景是透明的 [英] Can't get my DialogFragment background to be transparent

问题描述

就像是开发人员指南中所描述我创建了一个自定义的DialogFragment。
现在，我试图做听起来很简单，但我不能得到它的工作。
我已经定义：的android：背景=@机器人：彩色/透明在我的布局XML至极我加载像这样（在我的onCreateDialog）：

I have created a custom DialogFragment like it is described in the developer guide. Now what i am trying to do sounds simple enough, but i cannot get it to work. I have defined: android:background="@android:color/transparent" in my layout xml wich i am loading like this (in my onCreateDialog):

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

LayoutInflater inflater = getActivity().getLayoutInflater();


final View view = inflater.inflate(R.layout.pausedialog, null);
setStyle(STYLE_NO_FRAME, R.style.CustomDialog);

正如你可以看到我也试图设置自定义样式在DialogFragment至极的定义是这样的：

As you can see i also tried to set a custom style in the DialogFragment wich is defined like this:

<style name="CustomDialog" parent="android:style/Theme.Dialog">
    <item name="android:windowBackground">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowIsTranslucent">true</item> 
    <item name="android:alwaysDrawnWithCache">false</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

我也试过 getDialog（）getWindow（）setBackgroundDrawable（新ColorDrawable（0））;
这导致空指针异常。

And i also tried getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(0)); which leads to a null pointer exception.

我使用 android.support.v4.app.DialogFragment 。可这是原因？
还是我在做别的事情了？

I am using android.support.v4.app.DialogFragment. Can this be the cause? Or am i doing something else wrong?

如果您需要在对话框的截图，请让我知道！
谢谢

If you need a screenshot of the dialog please let me know! Thanks

推荐答案

尝试设置的风格和主题在你的dialogFragment类实现的onCreate方法。

Try to set style and theme in onCreate method of your dialogFragment class implementation.

@Override
    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
         int style=DialogFragment.STYLE_NO_TITLE;
         int theme=android.R.style.Theme_Translucent;
         setStyle(style, theme);
    }

或者

如果您正在使用Dialog类，那么你还可以设置样式和主题对话实例。

if you are using Dialog class then you can also set Style and theme on dialog instance.
