如何在 OnClick 视图事件中增加计数器 [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 监听器，它应该在被点击时无限期地增加计数器:

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 ++;
    }
});

问题是我似乎无法从 onclick 事件内部调用计数器，除非它设置为 final.但是，由于它是最终的，我也无法再更改它的值.

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.

我该如何解决这个问题?我想每次点击它时不断增加计数器，但我不能在 onclick 之外定义计数器，除非它是最终的，这意味着我不能再增加它.而且我也无法在 onclick 中定义计数器，因为它只会在我每次单击它时重置其值.

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 ++;
    }
});
