我正在寻找一种方法来获取自定义对话框的大小。 我经历了这个问题,但唯一给出的答案是无用的,因为如果我尝试mDialog.getWindow().getAttributes().height; 它只返回-2,这是我设置为对话的WRAP_CONTENT属性的常量。 我怎样才能得到它的大小。 我想知道背景图片的siye。
I am looking for a way to get size of a custom dialog. I went through this question, but the only answer given is pretty useless, because if I try mDialog.getWindow().getAttributes().height; it only returns -2, which is a constant for WRAP_CONTENT attribute which I set to dialog. How can I get the size of it. I want to know the siye for the background image.

实际上,在Android中,它不像iOS那样工作 - 但无法获得View本身的大小,但是您可以执行的操作是请求该视图的ROOT布局的大小。
例如:
myDialog.this.findViewById(R.id.dialog_root_layout).getHeight());
Actually, in Android it doesn't work like in iOS - you can't get the size of the View itself, what you can do, though, is to ask for the size of the ROOT layout of that view.
e.g.:
myDialog.this.findViewById(R.id.dialog_root_layout).getHeight());
