       int number=s.nextInt(3); 
       switch (number)

Answer 1

您需要使用

runOnUiThread(new Runnable() { 
    @Override 
    public void run() { 
} 
}); 

避免這種錯誤。

請檢查Android "Only the original thread that created a view hierarchy can touch its views."

您也可以只使用處理程序在指定的時間量後進行點擊按鈕，無需使用定時器。

這是每秒運行更簡單的方法。你不需要觸發按鈕。只是打電話要執行

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main);  

     Handler handler = new Handler(); 

     Runnable runnable = new Runnable(){ 
      @Override 
      public void run() { 
       buttonClick(); 
       if(handler!=null) 
        handler.postDelayed(runnable, 1000); 
      } 
     } 

     handler.postDelayed(runnable, 1000); 

    }
