Question

我正在尝试移动和成长一个RecyclerView，以便内容占据触摸输入的全屏。我希望RecyclerView能够保持向左和向右滚动的功能。

我无法让GestureDetector与RecyclerView一起正常工作。捕获onScrollChange不起作用，因为它可能无法滚动。我尝试onTouchEvent，但结果相当错误。有没有人有任何建议？

        mListView.setOnTouchListener(new View.OnTouchListener() {
        Float mHistoricX = null;
        Float mHistoricY = null;

        Float mHistoricX2 = null;
        Float mHistoricY2 = null;

        int mScrollDirection = 0;
        //1 = Left Right
        //2 = Up Down

        @Override
        public boolean onTouch(View v, MotionEvent e) {
            Log.d("TAG", "eX: " + e.getX() + " eY: " + e.getY());
            switch (e.getAction()) {

                    case MotionEvent.ACTION_UP:
                        Log.d("TAG", "ACTION_UP");

                        mHistoricX = null;

                            mHistoricX = e.getX();
                            mHistoricY = e.getY();
                        } else {
                            if(mScrollDirection == 0) {
                                float tempX = Math.abs(mHistoricX - e.getX());
                                float tempy = Math.abs(mHistoricY - e.getY());

                                if(tempX >= tempy) {
                                    mScrollDirection = 1;

                                }

                                mHistoricX2 =  mHistoricX - e.getX();
                                mHistoricY2 = mHistoricY - e.getY();

                            } else {
                                mHistoricX2 =  mHistoricX - e.getX();
                                mHistoricY2 = mHistoricY - e.getY();
                                Log.d("TAG", "X: " + mHistoricX2 + " Y: " + mHistoricY2);

                            }

                        }
                        break;
                    default:
                        break;

                }
            if(mScrollDirection == 2){
                mListView.animate().setDuration(0).xBy(-mHistoricX2).yBy(-mHistoricY2);
                return true;
            }

            return false;
        }
    });

在一个班级中移动以下代码。 {

holder.relMainOfRow.setOnTouchListener(new OnSwipeTouchListener(getActivity()) {

                @Override
                public void onClick() {
                    super.onClick();

                }

                @Override
                public void onLongClick() {
                    super.onLongClick();


                }



                public void onSwipeTop() {

                }

                public void onSwipeRight() {

                }

                public void onSwipeLeft() {

                }

                public void onSwipeBottom() {

                }
            });

}

使用此听众如下所述。 将Touch侦听器设置为行文件的父视图。 {

{{1}}

}
