IllegalStateException異常的Android應用程序，而試圖在模擬器中運行

Question

我在我的Android應用程序得到一個錯誤java.lang.IllegalStateException: Could not find a method onClick(View) in the activity class com.example.mysostest.MySOSTestActivity for onClick handler on view class android.widget.Button with id 'button1'它只有一個活動class.The錯誤是沒有顯示在logcat中，當我嘗試點擊應用程序的唯一按鈕（仿真器）

我添加的onClick方法在我的活動課，並與ID的按鈕：按鈕1。在這裏我如下的代碼

package com.example.mysostest;

    @Override

     getMenuInflater().inflate(R.menu.activity_my_sostest, menu); 
     return true; 
    } 

} 

我有在logcat中查看以下錯誤

我將不勝感激任何幫助。

Answer 1

你得到的錯誤，你指定的xml文件onClick財產，也和你也設置偵聽Java代碼相同的按鈕，太。

剛剛從XML文件中刪除onClick。或者只保留onClick並從java文件中移除監聽器。
