Java 在Android中如何在second或其他活动中运行方法？
我正在尝试制作一个游戏，我可以成功地切换到第二个活动，而实际上我的游戏就在第二个活动中，但当我在我的应用程序的第二个活动中单击按钮调用Dicerll方法时，我的应用程序总是崩溃。请帮帮我，我对安卓系统还不熟悉 这是代码，我也在最后附上了我的错误报告Java 在Android中如何在second或其他活动中运行方法？,java,android,android-studio,error-handling,runtime-error,Java,Android,Android Studio,Error Handling,Runtime Error,我正在尝试制作一个游戏，我可以成功地切换到第二个活动，而实际上我的游戏就在第二个活动中，但当我在我的应用程序的第二个活动中单击按钮调用Dicerll方法时，我的应用程序总是崩溃。请帮帮我，我对安卓系统还不熟悉 这是代码，我也在最后附上了我的错误报告 package com.example.ludobyjagtar; import androidx.appcompat.app.AppCompatActivity; import android.content.Intent; import an

掷骰子中）：
它期望整数值表示字符串资源id-因此出现错误：
android.content.res.Resources$NotFoundException: String resource ID #0x5 at
相反，你应该：
text.setText(Integer.toString(x));
查看您所有的setText
s是否存在类似错误。您是否在活动的xml代码中为按钮将方法的名称设置为onclick atribute？请也发布您的xml。我无法发布我的整个xml，但我已重新检查，并且xml中已经提到onclick。
text.setText(Integer.toString(x));
