DialogFragment在Android 4.4.2中有蓝线 [英] DialogFragment has blue line on top in Android 4.4.2

问题描述

我的对话框片段顶部出现一条蓝线，我无法摆脱（I甚至不知道它为什么会出现在第一位。有没有人知道如何摆脱这个？

There's a blue line appearing on top of my dialog fragment that I can't get rid off(I don't even know why does it appear in the first place. Does anybody know on how to get rid of this?

我在几台设备上测试了它的确有效在以后的Android版本上就好了。

I have tested it on several devices and it works just fine on later Android versions.

我的代码：

    private void setupDialog() {
    final Dialog dialog = getDialog();
    final Window window = dialog.getWindow();

    window.setBackgroundDrawable(new ColorDrawable(0));
    window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
    }

推荐答案

我想当它还有一个标题栏时会出现。我只是隐藏了标题栏，它工作得很好..

I guess it appears when there is still a title bar. I just hid the title bar and it works just fine..

    dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
