如何获得对话框大小?
我正在寻找一种获取自定义对话框大小的方法.我经历了 this 问题，但是唯一给出的答案是没有用的，因为如果我尝试 mDialog.getWindow().getAttributes().height; 它只返回 -2，这是 WRAP_CONTENT 属性的常量我设置为对话框.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.
推荐答案
实际上，在 Android 中它不像在 iOS 中那样工作 - 你无法获取 View 本身的大小，什么不过，您可以询问该视图的 ROOT 布局的大小.
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());
