问题描述

我想提出一个简单的游戏中，我得出了一组位图的上表面观在画布上..
现在我的主要活动，我有我的地方设计了一个按钮的线性布局。

i am making a simple game in which i draw a set of bitmaps on a canvas on surface view.. now in my main activity i have a linear layout where i have designed a button. in the onclick of this button i write:

setContentView(new surfaceviewclass(this));

它工作得很好......它打开surfaceview我玩游戏等。
但我想再次查看我开始从我的意思是，当游戏结束我希望菜单重新出现按钮..
我已经打过电话像虚空

main.menu();

but the app crashes.. please help.

推荐答案

请一个新的活动类和的onCreate写（）的方法就可以了。

Make a new activity class and write this in onCreate() method of it

setContentView(new surfaceviewclass(this));

和在previous活动创建一个Intent并在单击按钮时启动这一新的活动。

and in the previous activity create an Intent and start this new activity when button is clicked

e.g ....// onclick method of btn on old activity
    {
        Intent i=new Intent(OldClass.this, NewClass.class);
        startActivity(i);
    }
    ....
