android设定dialog宽高读：

http://blog.csdn.net/true100/article/details/43982763

mDialog = new Dialog(getActivity(), R.style.IsDelDialog);//自定义的样式，没有贴出代码来  
mDialog.setContentView(view);  
Window dialogWindow = mDialog.getWindow();  
WindowManager m = getActivity().getWindowManager();  
Display d = m.getDefaultDisplay(); // 获取屏幕宽、高度  
WindowManager.LayoutParams p = dialogWindow.getAttributes(); // 获取对话框当前的参数值  
        p.height = (int) (d.getHeight() \* 0.8); // 高度设置为屏幕的0.6，根据实际情况调整  
p.width = (int) (d.getWidth() \* 0.8); // 宽度设置为屏幕的0.65，根据实际情况调整  
dialogWindow.setAttributes(p);  
mDialog.show();
