推荐答案

您现在刚刚创建的视图，以便查看默认值设置为ZERO..after查看贴在窗口，你会得到正确的值..尝试得到这样的值 onWindowFocusChanged（）方法..

You are just now created the view so the View default values are set to be ZERO..after View attached to the window You will get the correct values..try get the values like this in onWindowFocusChanged() method..

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    Button button = (Button) findViewById(R.id.button2);
    System.out.println(button.getLeft());
    System.out.println(button.getRight());
}
