Question

我通过Recycler实施了ItemTouchHelper.SimpleCallback滑动效果，并在后视图上放置了一些按钮，这些按钮在翻转后显示。有趣的问题是当我点击按钮时不起作用。我应该按两次，在第三次尝试他们的工作！这是一个gif：

ItemTouchHelper.SimpleCallback simpleItemTouchCallback = new ItemTouchHelper.SimpleCallback(0,
                ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT ) {

            @Override
            public int getMovementFlags(RecyclerView recyclerView,
                                        RecyclerView.ViewHolder viewHolder) {
                int dragFlags = 0;
                int swipeFlags = ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT;
                return makeMovementFlags(dragFlags, swipeFlags);
            }

            @Override
            public boolean isItemViewSwipeEnabled() {
                return true;
            }

            @Override
            public boolean isLongPressDragEnabled() {
                return false;
            }

            @Override
            public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
                return false;
            }

            @Override
            public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
  ((InvoiceItemListAdapter.ViewHolder)viewHolder).lunchSwipeLeftEffect(dX);

            }

            @Override
            public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {

            }
        };

        recentInvoicesItemTouchHelper = new ItemTouchHelper(simpleItemTouchCallback);
        recentInvoicesItemTouchHelper.attachToRecyclerView(recentInvoiceRecyclerView);

这是我的RecyclerView.ViewHolder：

private class RecentInvoiceViewHolder extends RecyclerView.ViewHolder{

    private TextView price;
    private TextView hours;
    private TextView minutes;
    private TextView desc;
    private View color;
    private View sent;
    private View swipeActionsView;
    private View frontView;
    private Button print;
    private Button cancelSwipe;

    boolean swiped = false;

    public RecentInvoiceViewHolder(View view) {
        super(view);
        price    = (TextView) view.findViewById(R.id.invoice_review_in_day_price);
        hours    = (TextView) view.findViewById(R.id.invoice_review_in_day_hours);
        minutes  = (TextView) view.findViewById(R.id.invoice_review_in_day_minutes);
        desc     = (TextView) view.findViewById(R.id.invoice_review_in_day_decs);
        color    =  view.findViewById(R.id.invoice_review_in_day_color);
        sent     =  view.findViewById(R.id.invoice_review_in_day_sent_check);
        swipeActionsView     =  view.findViewById(R.id.swipe_actions);
        frontView     =  view.findViewById(R.id.front_view);
        print     = (Button) view.findViewById(R.id.print_recent_invoice);
        cancelSwipe     = (Button) view.findViewById(R.id.cancel_swipe);

        cancelSwipe.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                frontView.setTranslationX(0);
                frontView.setVisibility(View.VISIBLE);
                swiped = false;
            }
        });
    }

    public void lunchSwipeEffect(float dx){
        if(!swiped)
            frontView.setTranslationX(dx);//TranslationX(dx);
        if(Math.abs(dx)> frontView.getMeasuredWidth()) {
            swiped = true;
            frontView.setVisibility(View.GONE);
        }
    }

}

最后这是我的ViewHolder布局：

并且recyclerView位于NestedScrollView，具有折叠工具栏效果哪个视图消耗两次首次点击？!!

Answer 1

ItemTouchHelper抓住了RecyclerView的压力

Android：点击在转换后对Recycler Item不起作用
