onClick、onLongClick 同时滑动

onClick, onLongClick and swipe at the same time

我正在开发具有列表视图的应用程序,并且在此列表的每个单元格上:

问题发生在我尝试滑动时,我也同时打开了对话框。 (onLongClick 和 Swipe 同时激活)

这是我的代码:

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 = 200;

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

        @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();
                        }
                    }
                    Log.e("diffX", String.valueOf(diffX));
                    Log.e("velocityX", String.valueOf(velocityX));
                    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() {
    }
}

点击、长按的代码:

view.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

             Intent intent = new Intent(MainActivity.this, secondActivity.class);

                    startActivity(intent);
                }
            });
           view.setOnLongClickListener(new View.OnLongClickListener() {

                @Override
                public boolean onLongClick(View v) {
                    Log.e("LongClick", "Long click");


                  // code for the dialog
                }
            });

           view.setOnTouchListener(new OnSwipeTouchListener(MainActivity.this) {
                public void onSwipeTop() {
                    Toast.makeText(MainActivity.this, "top", Toast.LENGTH_SHORT).show();
                }

                public void onSwipeRight() {
                    Toast.makeText(MainActivity.this, "right", Toast.LENGTH_SHORT).show();
                }

                public void onSwipeLeft() {
                    Toast.makeText(MainActivity.this, "left", Toast.LENGTH_SHORT).show();
                }

                public void onSwipeBottom() {
                    Toast.makeText(MainActivity.this, "bottom", Toast.LENGTH_SHORT).show();
                }

            });

        }

本质上,您将在 ListView 前面创建一个透明视图,它使用水平运动事件并将非水平运动事件向下传递回 ListView。

为什么要单独设置OnLongClickListener?!? 在 OnSwipeTouchListener class 中覆盖 GestureListeneronLongPress(MotionEvent e) 方法,它应该可以工作。
