最近开发老遇到莫名其妙的问题，dialog自定义大小，setAttributes这个方法没反应是肿么一回事

DownLoaderDialog dialog=new DownLoaderDialog(MainActivity.this,R.style.dialog);
Window mwindow=dialog.getWindow();
WindowManager.LayoutParams lp=mwindow.getAttributes();
int[] location = new int[2];
button.getLocationOnScreen(location);
WindowManager m = getWindowManager();
Display d = m.getDefaultDisplay();
lp.y=location[1];
lp.height = (int) (d.getHeight() * 0.6);
mwindow.setAttributes(lp);
dialog.show();

<?xml version="1.0" encoding="utf-8"?>
