Android的工作室 - 上的任何按钮Clicklistener？ [英] Android Studio - Clicklistener on any button?

问题描述

所以我还在学习Android的工作室，我试图通过制作一个简单的捶一个痣类型游戏蒙混过关我的路。 9按钮网格是隐藏的，当点击一个按钮一个随机数生成器设置一个int变量，然后通过设置一个按钮的可视性交换机出现。

So I'm still learning Android Studio and I'm trying to muddle my way through making a simple whack-a-mole type game. A grid of 9 buttons are hidden and when one button is clicked a random number generator set an int variable which then goes through a switch which sets the visibility of the next button.

这一直很好，直到我要添加+1到比分INT。每个按钮都有它自己的clicklistener用if语句检查它是否已经显现等，我不能让他们都来，因为它需要被声明为final，但是当更新同一个变量开关和它自己的（非常低效当然）副本我这样做，只是说不能分配变量。

This has been fine until I want to add +1 to a score int. Each button has it's own clicklistener with it's own (very inefficient of course) copy of the switch and if statement checking whether it's already visible etc and I can't get them all to update the same variable as it needs to be declared final but when I do it just says cannot assign variable.

所以是有可能做一个像上的任何按钮，而不是特定的一个而clicklistener？然后，我可以定义和更新一个方法变量（如果这是正确的术语）。

So is it possible to do a something like a clicklistener on ANY button rather than a specific one? Then I could define and update the variable in that one method (if that's the right terminology).

下面是第一个按钮的外观进行快速复印就像是可见的，直到第一次点击 -

Here's a quick copy of what the first button looks like which is visible until first clicked -

button0.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            button0.setVisibility(View.INVISIBLE);
            Random rand = new Random();
            int n = rand.nextInt(9);

            switch (n) {
                case 0:
                    if(button0.getVisibility() == View.INVISIBLE){
                        button0.setVisibility(View.VISIBLE);
                    }else{
                        button0.setVisibility(View.INVISIBLE);
                    }
                    break; ... and so on

所以想什么，我是这样的（这显然作品） -

And so what I'd like is something like this (that obviously works) -

    button0 or button1 or button2 or button3 or button4.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            int scoreint = 0;
            scoreint++;
            scoreText.setText(""+scoreint);  
        };

就像我说的，我知道这是做事情的最没有效率的和最慢的方式，但我仍然在学习和喜欢做的事情最简单的，愚蠢的方式，使我能得到的核心概念。我看教程太多，但我像一个小方项目要进了。感谢您的帮助！

Like I said, I know this is the most inefficient and slowest way of doing things but I'm still learning and like doing things the simplest, stupidest way so I can get the core concepts. I am watching tutorials too but I like a little side project to get into too. Thanks for any help!

推荐答案

我一跳code这个皮斯帮助您

i hop this pease of code helps you

public class MainActivity extends ActionBarActivity  implements View.OnClickListener{



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


    button0 = (Button)findViewById(R.id.button0);
    button0.setOnClickListener(this);

    button1 = (Button)findViewById(R.id.button1);
    button1.setOnClickListener(this);

    //and on ....
    }

 public void onClick(View view)
{
     switch (view.getId())
     {
         case R.id.button0 :
        // do sum thing 
          break;
         case R.id.button1 :
        // do sum thing 
          break;
     }

}

}
