在android系统加载按钮点击新的一页？ [英] Load new page on button click in android?

问题描述

我在做Android的游戏。我想要有两个按钮，一个开始游戏，一个以显示主菜单画面如何筛选。

I am making a game in android. I want to make a main menu screen that has two buttons, one to start the game and one to display the how to screen.

我班有两个，但是当我启动我的名字和测试按钮，应用程序崩溃。可能有人请告诉我什么是错我的code？

I have classes for both, but when I launch my name and test the buttons, the application crashes. Could someone please tell me what is wrong with my code?

       public void launch()
       {
            Intent i = new Intent();
            i.setClassName("com.testing.blockinvasion", "com.testing.blockinvasion.game");
            startActivity(i);
       }

       public void howto()
       {
            Intent i = new Intent();
            i.setClassName("com.testing.blockinvasion", "com.testing.blockinvasion.howto");
            startActivity(i);
       }

}

我的按钮都在我的定义main.xml中：

My buttons are defined in my main.xml:

 <Button
     android:layout_height="wrap_content"
     android:layout_width="wrap_content"
     android:text="@string/Start"
     android:onClick="launch" />

编辑：最后我只是删除该项目，并开始另一个，一切似乎现在工作得很好。

I ended up just deleting the project and starting another one and everything seems to work fine now.

推荐答案

您需要正确的方法签名。所以，做这种方式：

You need to correct your method signatures. So do it in this way:

public void launch(View v)

和

public void howto(View v)
