我有为RecyclerVIEw处理singleClickListener的类.我正在使用GestureDetector处理点击.如何将LongPressListener添加到同一类中以同时处理它们？

public class RecyclerVIEwItemClickListener implements RecyclerVIEw.OnItemtouchListener {    private OnItemClickListener mListener;    public interface OnItemClickListener {        public voID onItemClick(VIEw vIEw, int position);    }    GestureDetector mGestureDetector;    public RecyclerVIEwItemClickListener(Context context, OnItemClickListener Listener) {        mListener = Listener;        mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {            @OverrIDe            public boolean onSingleTapUp(MotionEvent e) {                return true;            }            @OverrIDe            public boolean onDown(MotionEvent event) {                // triggers first for both single tap and long press                return true;            }            @OverrIDe            public voID onLongPress(MotionEvent event) {                //...                super.onLongPress(event);            }        });    }    @OverrIDe    public boolean onIntercepttouchEvent(RecyclerVIEw vIEw, MotionEvent e) {        VIEw childVIEw = vIEw.findChildVIEwUnder(e.getX(), e.getY());        if (childVIEw != null && mListener != null && mGestureDetector.ontouchEvent(e)) {            mListener.onItemClick(childVIEw, vIEw.getChildAdapterposition(childVIEw));        }        return false;    }    @OverrIDe    public voID ontouchEvent(RecyclerVIEw vIEw, MotionEvent motionEvent) {    }

我在活动中使用此类的类：

recyclerVIEw.addOnItemtouchListener(                new RecyclerVIEwItemClickListener(this, new RecyclerVIEwItemClickListener.OnItemClickListener() {                    @OverrIDe public voID onItemClick(VIEw vIEw, int position) {                        // Todo Handle item click                        Log.d(TAG, "item clicket position: " + position);                    }                })        );

解决方法:

如果您想在onIntercepttouchEvent上都处理它们,只需像这样使用它.

public class RecyclerItemClickListener implements RecyclerVIEw.OnItemtouchListener {private OnItemClickListener mListener;private VIEw childVIEw;private RecyclerVIEw vIEwRecycle;public interface OnItemClickListener {    voID onItemClick(VIEw vIEw, int position);    voID onLongItemClick(VIEw vIEw, int position);}GestureDetector mGestureDetector;public RecyclerItemClickListener(Context context, OnItemClickListener Listener) {    mListener = Listener;    mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {        @OverrIDe        public boolean onSingleTapUp(MotionEvent e) {            if (childVIEw != null && mListener != null){                mListener.onItemClick(childVIEw, vIEwRecycle.getChildAdapterposition(childVIEw));            }            return true;        }        @OverrIDe        public voID onLongPress(MotionEvent e) {            if (childVIEw != null && mListener != null) {                mListener.onLongItemClick(childVIEw, vIEwRecycle.getChildAdapterposition(childVIEw));            }            super.onLongPress(e);        }    });}@OverrIDepublic boolean onIntercepttouchEvent(RecyclerVIEw vIEw, MotionEvent e) {    AppHelper.AppLogger("insIDe");    childVIEw = vIEw.findChildVIEwUnder(e.getX(), e.getY());    vIEwRecycle = vIEw;    mGestureDetector.ontouchEvent(e);    return false;}@OverrIDepublic voID ontouchEvent(RecyclerVIEw vIEw, MotionEvent motionEvent) {}@OverrIDepublic voID onRequestdisallowIntercepttouchEvent(boolean disallowIntercept) {}
