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.
推荐答案
实际上,在Android中,它不像iOS那样工作 - 你无法获得 View
本身的大小,但是您可以做的是要求该方面的 ROOT 布局的大小查看。
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.
例如:
myDialog.this.findViewById(R.id。 dialog_root_layout).getHeight());
