最初にアイテムをスワイプするか、フルスワイプを実行するか、現在のポイントで停止する必要があります。 Yandexメールのように。私はクラスItemTouchHelpersのある時点でスワイプを止めるには？
ItemTouchHelperCallback extends ItemTouchHelper.Callback
と私、私は似た何かをするために必要な方法
@Override
public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
View itemView = viewHolder.itemView;
// not sure why, but this method get's called for viewholder that are already swiped away
if (viewHolder.getAdapterPosition() == -1) {
// not interested in those
return;
}
float height = (float) itemView.getBottom() - (float) itemView.getTop();
float width = height/3;
float temdX=0;
Bitmap icon;
if(dX > 0 || lastdX>0){
//try stop item while back in dx=0, but workin only while i debug
if(lastdX>=100 && dX==0 &&lastdX!=0 &&lastdX!=-720)
{
dX=100;
isCurrentlyActive=true;
}
lastdX=dX;
itemView.setLeft((int) dX);
p.setColor(Color.GREEN);
RectF background = new RectF((float) itemView.getLeft(), (float) itemView.getTop(), dX,(float) itemView.getBottom());
c.drawRect(background,p);
icon = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.ic_y);
RectF icon_dest = new RectF((float) itemView.getLeft() + width ,(float) itemView.getTop() + width, (float) itemView.getLeft()+ 2*width,(float)itemView.getBottom() - width);
c.drawBitmap(icon, null, icon_dest, p);
} else if(lastdX<0 || dX<0) {
if(lastdX<=-100 && dX==0 &&lastdX!=0 &&lastdX!=720)
{
dX=-100;
//itemView.setTranslationX(-200);
isCurrentlyActive=true;
}
lastdX=dX;
itemView.setRight((int)(dX));
p.setColor(Color.RED);
