Answer 1

您需要使用

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

避免这种错误。

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

您也可以只使用处理程序在指定的时间量后进行点击按钮，无需使用定时器。

Answer 2

这是每秒运行更简单的方法。你不需要触发按钮。只是打电话要执行

@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); 

    }
