带有圆角的Android AlertDialog:在圆角下方看到矩形 [英] Android AlertDialog with rounded corners: rectangle seen below corners

问题描述

我想要一个带有圆角的Dialog，但是当看到Dialog时，在它的下方有一个矩形，它在角的下方可见，就像这样:

I want a Dialog with rounded corners, but when the Dialog is seen there's a rectangle below it that's seen below the corners, like this:

我使用自定义的DialogFragment构建dialog:

public class MyDialogFragment extends DialogFragment{
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    LayoutInflater inflater = getActivity().getLayoutInflater();

    builder.setView(inflater.inflate(R.layout.playdialog, null));
    return builder.create();
}
}

对话框布局(播放对话框)具有以下可绘制背景作为背景:

The dialog layout (playdialog) has the following drawable as background:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >

    <solid
        android:color="#AAAAAAAA" />

    <stroke
        android:width="2dp"
        android:color="#FF000000" />

    <corners android:radius="20dp" />
</shape>

正如我所说，我将此可绘制对象设置为背景:

As I said, I set this drawable as background:

android:background="@drawable/dialog_background"

我不希望看到该矩形.我该怎么办?

I don't want that rectangle to be seen. How can I do it??

在此帖子中，用户遇到了同样的问题.我尝试使用对他有用的解决方案，但对我不起作用.我这样修改了DialogFragment:

In this post the user had the same problem. I tried to use the solution that worked for him but it didn't work for me. I modified my DialogFragment like this:

public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    LayoutInflater inflater = getActivity().getLayoutInflater();

    builder.setView(inflater.inflate(R.layout.playdialog, null));
    Dialog d = builder.create();
    d.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

    return d;
}

结果完全相同.如何删除该矩形?

The result is exactly the same. How can I remove that rectangle?

谢谢！

推荐答案

当我遇到相同的问题时，我感到非常震惊，解决方案也有些奇怪.创建自己的自定义可绘制对象，例如参见下文.

I was shocked when I occured the same problem, the solution is also a little weird. Create your own custom drawable for eg see below.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <solid android:color="@color/text_highlight" />

    <stroke
        android:width="5dp"
        android:color="@color/text_highlight" />

    <corners android:radius="12dp" />

    <stroke
        android:width="1dp"
        android:color="@android:color/transparent" />

</shape>

在对话框中添加以下行:

Add the following lines to your dialog:

 dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

 // This is line that does all the magic
 dialog.getWindow().setBackgroundDrawableResource(                             
 R.drawable.dialog_rounded);
