WearableListView LongClick

Question

我一直在尝试添加一个longClickListener到WearableListView

这是我目前所做的:

listView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View view) {
            Toast.makeText(getActivity(), "Long", Toast.LENGTH_SHORT).show();
            return false;
        }
    });

这里的listView是一个weararabelistview。当我长按时，函数没有被调用。我明白，对于单次点击，我们必须设置listView.setClickListener()而不是listView.setOnClickListener()，是否有类似的方法来长点击?

谢谢!

尝试使用onItemLongClick代替LongClick

listView.setOnItemLongClickListener(new OnItemLongClickListener() {
        public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                int pos, long id) {
            // TODO Auto-generated method stub
            Log.v("long clicked","pos: " + pos);
            return true;
        }
    });

刚刚看到这个。我的破解方案是扩展wearableListView并重写它的onTouch方法来查看是否有一个长触摸被完成。还要确保触摸发生在中心项目上。我必须在项目视图中添加一个居中布尔值。

  @Override
public boolean onTouchEvent(MotionEvent event) {
    if(!this.isEnabled()) {
        return false;
    } else {
        switch (event.getActionMasked()) {
            case MotionEvent.ACTION_DOWN:
                moved = false;
                timestamp = System.currentTimeMillis();
                initialTouch = event.getRawX();
                //handler.postDelayed(mLongPressed, 1000);
                break;
            case MotionEvent.ACTION_UP:
                //handler.removeCallbacks(mLongPressed);
                if (!moved && timestamp + 1000 < System.currentTimeMillis()) {
                    Rect rect;
                    for(int i = 0;i<getChildCount();i++){View v = getChildAt(i);
                        if(v instanceof WearableListItemSensor){
                            if(((WearableListItemSensor) v).isCenter) {
                                rect = new Rect(v.getLeft(), v.getTop(), v.getRight(), v.getBottom());
                                if(rect.contains( (int) event.getX(), (int) event.getY())){
                                    //long pressed center
                                    if (mLongClickListener != null)
                                        mLongClickListener.onLongClick((int)v.getTag());
                                }
                                return true;
                            }
                        }
                    }
                }
                break;
            case MotionEvent.ACTION_MOVE:
                //handler.removeCallbacks(mLongPressed);
                if(Math.abs(event.getRawX() - initialTouch) >= 2)
                    moved=true;
                break;
        }
        return super.onTouchEvent(event);
