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()
      }
    }
 )

OnSwipeTouchListener.java:

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;

public class OnSwipeTouchListener implements OnTouchListener {

    private final GestureDetector gestureDetector;

    public OnSwipeTouchListener (Context ctx){
        gestureDetector = new GestureDetector(ctx, new GestureListener());
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return gestureDetector.onTouchEvent(event);
    }

    private final class GestureListener extends SimpleOnGestureListener {

        private static final int SWIPE_THRESHOLD = 100;
        private static final int SWIPE_VELOCITY_THRESHOLD = 100;

        @Override
        public boolean onDown(MotionEvent e) {
            return true;
        }

        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            boolean result = false;
            try {
                float diffY = e2.getY() - e1.getY();
                float diffX = e2.getX() - e1.getX();
                if (Math.abs(diffX) > Math.abs(diffY)) {
                    if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                        if (diffX > 0) {
                            onSwipeRight();
                        } else {
                            onSwipeLeft();
                        }
                        result = true;
                    }
                }
                else if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffY > 0) {
                        onSwipeBottom();
                    } else {
                        onSwipeTop();
                    }
                    result = true;
                }
            } catch (Exception exception) {
                exception.printStackTrace();
            }
            return result;
        }
    }

    public void onSwipeRight() {
    }

    public void onSwipeLeft() {
    }

    public void onSwipeTop() {
    }

    public void onSwipeBottom() {
    }
}

用法:

imageView.setOnTouchListener(new OnSwipeTouchListener(MyActivity.this) {
    public void onSwipeTop() {
        Toast.makeText(MyActivity.this, "top", Toast.LENGTH_SHORT).show();
    }
    public void onSwipeRight() {
        Toast.makeText(MyActivity.this, "right", Toast.LENGTH_SHORT).show();
    }
    public void onSwipeLeft() {
        Toast.makeText(MyActivity.this, "left", Toast.LENGTH_SHORT).show();
    }
    public void onSwipeBottom() {
        Toast.makeText(MyActivity.this, "bottom", Toast.LENGTH_SHORT).show();
    }

});

如果你还需要处理点击事件，这里做一些修改:

public class OnSwipeTouchListener implements OnTouchListener {

    private final GestureDetector gestureDetector = new GestureDetector(new GestureListener());

    public boolean onTouch(final View v, final MotionEvent event) {
        return gestureDetector.onTouchEvent(event);
    }

    private final class GestureListener extends SimpleOnGestureListener {

        private static final int SWIPE_THRESHOLD = 100;
        private static final int SWIPE_VELOCITY_THRESHOLD = 100;


        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            boolean result = false;
            try {
                float diffY = e2.getY() - e1.getY();
                float diffX = e2.getX() - e1.getX();
                if (Math.abs(diffX) > Math.abs(diffY)) {
                    if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                        if (diffX > 0) {
                            result = onSwipeRight();
                        } else {
                            result = onSwipeLeft();
                        }
                    }
                } else {
                    if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                        if (diffY > 0) {
                            result = onSwipeBottom();
                        } else {
                            result = onSwipeTop();
                        }
                    }
                }
            } catch (Exception exception) {
                exception.printStackTrace();
            }
            return result;
        }
    }

    public boolean onSwipeRight() {
        return false;
    }

    public boolean onSwipeLeft() {
        return false;
    }

    public boolean onSwipeTop() {
        return false;
    }

    public boolean onSwipeBottom() {
        return false;
    }
}

以及示例用法:

    background.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            toggleSomething();
        }
    });
    background.setOnTouchListener(new OnSwipeTouchListener() {
        public boolean onSwipeTop() {
            Toast.makeText(MainActivity.this, "top", Toast.LENGTH_SHORT).show();
            return true;
        }
        public boolean onSwipeRight() {
            Toast.makeText(MainActivity.this, "right", Toast.LENGTH_SHORT).show();
            return true;
        }
        public boolean onSwipeLeft() {
            Toast.makeText(MainActivity.this, "left", Toast.LENGTH_SHORT).show();
            return true;
        }
        public boolean onSwipeBottom() {
            Toast.makeText(MainActivity.this, "bottom", Toast.LENGTH_SHORT).show();
            return true;
        }
    });

这个问题仍然存在。添加以下类:

private class SwipeFirstTouchListener implements View.OnTouchListener {

    private final DirtyOnSwipeTouchListener swipe;
    private final View.OnTouchListener delegate;

    private SwipeFirstTouchListener(DirtyOnSwipeTouchListener swipe, View.OnTouchListener delegate) {
        this.swipe = swipe;
        this.delegate = delegate;
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (!swipe.onTouch(v, event)) {
            // no a swipe, so lets try with the rest of the events
            return delegate.onTouch(v, event);
        }
        return false;
    }
}

and

private class DirtyOnSwipeTouchListener extends OnSwipeTouchListener {
    private boolean dirty = false;
    private OnSwipeTouchListener delegate;

    public DirtyOnSwipeTouchListener(Context ctx, OnSwipeTouchListener delegate) {
        super(ctx);

        this.delegate = delegate;
    }

    private void reset() {
        dirty = false;
    }

    public void onSwipeTop() {
        dirty = true;

        delegate.onSwipeTop();
    }

    public void onSwipeRight() {
        dirty = true;
        delegate.onSwipeRight();
    }

    public void onSwipeLeft() {
        dirty = true;
        delegate.onSwipeLeft();
    }

    public void onSwipeBottom() {
        dirty = true;
        delegate.onSwipeBottom();
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        try {
            super.onTouch(v, event);

            return dirty;
        } finally {
            dirty = false;
        }

    }
};

还有一个在网上找到的课程:

public class OnSwipeTouchListener implements OnTouchListener {
    
    private static final String TAG = OnSwipeTouchListener.class.getName();

    private final GestureDetector gestureDetector;

    public OnSwipeTouchListener(Context ctx) {
        gestureDetector = new GestureDetector(ctx, new GestureListener());
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return gestureDetector.onTouchEvent(event);
    }

    private final class GestureListener extends GestureDetector.SimpleOnGestureListener {

        private static final int SWIPE_THRESHOLD = 100;
        private static final int SWIPE_VELOCITY_THRESHOLD = 100;

        @Override
        public boolean onDown(MotionEvent e) {
            return true;
        }

        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            boolean result = false;
            try {
                float diffY = e2.getY() - e1.getY();
                float diffX = e2.getX() - e1.getX();
                if (Math.abs(diffX) > Math.abs(diffY)) {
                    if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                        if (diffX > 0) {
                            onSwipeRight();
                        } else {
                            onSwipeLeft();
                        }
                        result = true;
                    }
                } else if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffY > 0) {
                        onSwipeBottom();
                    } else {
                        onSwipeTop();
                    }
                    result = true;
                }
            } catch (Exception exception) {
                Log.d(TAG, "Unexpected problem handling swipes, ignoring.", exception);
            }
            return result;
        }
    }

    public void onSwipeRight() {
        // Do nothing
    }

    public void onSwipeLeft() {
        // Do nothing
    }

    public void onSwipeTop() {
        // Do nothing
    }

    public void onSwipeBottom() {
        // Do nothing
    }
}

然后添加你自己的OnTouchListener和OnSwipeTouchListener，如下所示:

    DirtyOnSwipeTouchListener swipe = new DirtyOnSwipeTouchListener(this, new OnSwipeTouchListener(this) {
        public void onSwipeTop() {
            // your code here
        }

        public void onSwipeRight() {
            // your code here
        }

        public void onSwipeLeft() {
            // your code here
        }

        public void onSwipeBottom() {
            // your code here
        }
    });


    View.OnTouchListener toggleListener = new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_UP) {
                // your code here

                return true;
            } else if (event.getAction() == MotionEvent.ACTION_DOWN) {
                // your code here

                return true;
            }
            return false;
        }
    };

    SwipeFirstTouchListener swipeFirstTouchListener = new SwipeFirstTouchListener(swipe, toggleListener);

    myView.setOnTouchListener(swipeFirstTouchListener);

我一直在做类似的事情，但仅限于水平滑动

import android.content.Context
import android.view.GestureDetector
import android.view.MotionEvent
import android.view.View

abstract class OnHorizontalSwipeListener(val context: Context) : View.OnTouchListener {    

    companion object {
         const val SWIPE_MIN = 50
         const val SWIPE_VELOCITY_MIN = 100
    }

    private val detector = GestureDetector(context, GestureListener())

    override fun onTouch(view: View, event: MotionEvent) = detector.onTouchEvent(event)    

    abstract fun onRightSwipe()

    abstract fun onLeftSwipe()

    private inner class GestureListener : GestureDetector.SimpleOnGestureListener() {    

        override fun onDown(e: MotionEvent) = true

        override fun onFling(e1: MotionEvent, e2: MotionEvent, velocityX: Float, velocityY: Float)
            : Boolean {

            val deltaY = e2.y - e1.y
            val deltaX = e2.x - e1.x

            if (Math.abs(deltaX) < Math.abs(deltaY)) return false

            if (Math.abs(deltaX) < SWIPE_MIN
                    && Math.abs(velocityX) < SWIPE_VELOCITY_MIN) return false

            if (deltaX > 0) onRightSwipe() else onLeftSwipe()

            return true
        }
    }
}

然后它可以用于视图组件

private fun listenHorizontalSwipe(view: View) {
    view.setOnTouchListener(object : OnHorizontalSwipeListener(context!!) {
            override fun onRightSwipe() {
                Log.d(TAG, "Swipe right")
            }

            override fun onLeftSwipe() {
                Log.d(TAG, "Swipe left")
            }

        }
    )
}

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.
