我创建了一个对话框，如下所示：

final Dialog dialog = new Dialog( context );
dialog.setContentView( R.layout.item_give_review );
dialog.getWindow().setBackgroundDrawable( new ColorDrawable( Color.TRANSPARENT ) );
dialog.setCancelable( true );
dialog.setCanceledOnTouchOutside(true);
dialog.show();

哪里 item_give_review 是一个 NestedScrollView 包含的对象很少：

现在，当用户在对话框外单击时，我希望对话框关闭，但是我注意到它不能与margin一起工作。
为了让它工作，我不得不删除的边缘和设置的尺寸 nestedScrollView .
有没有什么办法，我将能够使用保证金和解散时，点击外面？
