按住一个按钮，使计数器每次都加1 [英] Keep pressing a button so that a counter keeps adding by 1 every time

问题描述

我在想是否有一种简单的方法可以按住同一个按钮，这样计数器每次都会增加1。因此，如果单击按钮两次，则计数器总计为2，因此允许第二个if语句起作用。

I was thinking if there was a simple way to keep pressing the same button so that the counter keeps adding by 1 every time. So that if the button is clicked two times it will have a counter total of 2 therefore allowing the second if statement to function.

int counter = 0;

if(view.getId()=R.id.Spinbtn){
  counter ++;

  if(counter==2){
     showcalcuation(); 
  }
}

推荐答案

首先，让你的班级全球化：

First, make this global within your class:

int counter = 0;  

然后实施按钮点击事件：

Then implement the button click event:

 final Button button = (Button) findViewById(R.id.Spinbtn);
          button.setOnClickListener(new View.OnClickListener() {
               public void onClick(View view) {
                    if(view.getId() == R.id.Spinbtn){
                         if(counter == 2){
                            showcalcuation();
                         }else if(counter < 2){
                            counter += 1;
                         }
                    }
               }
          });
