如何在OnClick View事件中增加计数器 [英] How to increment a Counter inside an OnClick View Event

问题描述

我知道这听起来很基础，但这是我的问题:

I know this might sound very basic but here's my problem:

我有一个onclickevent侦听器，该监听器应该在单击时无限期递增计数器:

I have an onclickevent listener that's supposed to increment the counter indefinitely when it's clicked:

final int counter = 0;
myimageView2.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        counter ++;
    }
});

问题在于，除非将onclick事件设置为 final ，否则我似乎无法从onclick事件中调用该计数器.但是，由于它是最终的，所以我也无法再更改其值.

The problem is that I can't seem to call the counter from inside the onclick event unless it's set to final. However since it's final I can no longer change its value either.

我尝试将计数器放在onclick事件中，即:

I tried placing the counter within the onclick event, i.e.:

myimageView2.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        int counter = 0;
        counter ++;
    }
});

但是，单击它也会将计数器重置为零.

However, clicking it also resets the counter back to zero.

我该如何解决?我想每次点击计数器都会不断增加它的数量， 但是除非最后一次，否则我无法在onclick之外定义计数器，这意味着我无法再对其进行递增.而且我也无法在onclick内定义计数器，因为它只会在每次单击时重置其值.

How do I solve this? I want to continuously increment the counter each time I click it, but I can't define the counter outside of the onclick unless it's final, which means I can no longer increment it. And I can't define the counter inside the onclick either since it will only reset its value each time I click it.

推荐答案

已解决:

myimageView2.setOnClickListener(new OnClickListener() {
    int counter = 0;
    public void onClick(View v) {
        counter ++;
    }
});
