我想要一个带有圆角的Dialog,但是当看到Dialog时,在它的下面有一个矩形,它在角下是可见的,如下所示:

我使用自定义dialog构建DialogFragment:

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:
<?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>

就像我说的,我将这个可绘制对象设置为背景:
android:background="@drawable/dialog_background"

我不希望看到该矩形。我该怎么做??

this帖子中,用户有同样的问题。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:
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;
}

结果是完全一样的。如何删除该矩形?

谢谢!

最佳答案

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。

<?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>

将以下行添加到对话框中:
 dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

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