几乎所有东西都可以在我一直在研究的程序中运行。当我在 中进行更改时UI,一切都设置正确。由于我无法弄清楚的原因,当我按下我的 main 的 enter 按钮时,UI应用程序强制异常关闭。从日志...

java.lang.IllegalStateException:在 id 为“enterButtonID”的视图类 android.widget.Button 上的 onClick 处理程序的活动类 com.loch.meaptracker.MainActivity 中找不到方法 enterMood(View)

这是程序代码。Eclipse 不会标记任何错误或警告。看着这个,我有点茫然,非常疲惫。任何帮助将不胜感激。

请检查 XML 代码。我认为在您的 XML 标记中,您添加了一个属性 android:onClick="enterMood".... 尝试删除它并运行它

利用

android:onClick="dialogPop" 代替

您的点击处理程序格式不正确。它需要包含一个视图参数,以便 XML 单击处理程序正常工作。

public void getMood(View view){

}
