Android Kotlin onTouchListener希望我覆盖performClick() [英] Android kotlin onTouchListener wants me to override performClick()

问题描述

在Android Studio希望我的onTouchListener覆盖我执行的performClick的情况下，我试图摆脱警告，但该警告仍然存在.

I'm trying to get rid of a warning where Android Studio wants my onTouchListener to override performClick which I do, but the warning remains.

draggableBar!!.setOnTouchListener(View.OnTouchListener { view, motionEvent ->
    when (motionEvent.getAction()) {
        MotionEvent.ACTION_DOWN -> {

        }
        MotionEvent.ACTION_UP -> {
            view.performClick()
        }
    }

    return@OnTouchListener true
})

这可能是Android Studio的错误，还是我做错了什么?

Could this be an Android Studio bug or am I doing something wrong?

推荐答案

好的，我有同样的问题，但是我通过覆盖onTouch侦听器来解决了.

Okay, I have the same problem but i fixed it by overriding the onTouch listener.

默认的onTouch希望我们覆盖performClick()，但是即使通过view.performClick()调用该方法也无法正常工作.

The default onTouch wants us to override performClick(), but this does not work even calling the method by view.performClick().

因此，请像这样覆盖您的onTouch:

So therefore override your onTouch like this:

override fun onTouch(view: View, motionEvent: MotionEvent): Boolean {
    when (view) {
        draggableBar -> {
            when (motionEvent.getAction()) {
                MotionEvent.ACTION_DOWN -> {

                }
                MotionEvent.ACTION_UP -> {
                    view.performClick()
                }
            }
        }
        otherButtonHere -> {
            //your welcome
        }
    }

    return true
}

通过这种方式，您可以在所有可单击的视图中使用单个onTouch().

And in that way, you can use single onTouch() in all clickable views you have.

别忘了实现您的班级:

View.OnTouchListener

并设置监听器:

draggableBar!!.setOnTouchListener(this)
