如何做到这一点?

爱德华·布雷的回答在科特林的使用
view.setOnTouchListener(object: OnSwipeTouchListener(this) {
override fun onSwipeLeft() {
super.onSwipeLeft()
}
override fun onSwipeRight() {
super.onSwipeRight()
}
}

@Edward Brey的方法很有效。如果有人也想复制和粘贴导入的OnSwipeTouchListener,他们是:
import android.content.Context;
import android.view.GestureDetector;
import android.view.GestureDetector.SimpleOnGestureListener;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
使用SwipeListView,让它为你处理手势检测。
If you want to display some buttons with actions when an list item is swipe are a lot of libraries on the internet that have this behavior. I implemented the library that I found on the internet and I am very satisfied. It is very simple to use and very quick. I improved the original library and I added a new click listener for item click. Also I added font awesome library (http://fortawesome.github.io/Font-Awesome/) and now you can simply add a new item title and specify the icon name from font awesome.

这个问题很多年前就有人问过了。现在,有一个更好的解决方案:SmartSwipe: https://github.com/luckybilly/SmartSwipe
代码如下所示:
SmartSwipe.wrap(contentView)
.addConsumer(new StayConsumer()) //contentView stay while swiping with StayConsumer
.enableAllDirections() //enable directions as needed
.addListener(new SimpleSwipeListener() {
@Override
public void onSwipeOpened(SmartSwipeWrapper wrapper, SwipeConsumer consumer, int direction) {
//direction:
// 1: left
// 2: right
// 4: top
// 8: bottom
}
})
;
