recyclerview怎么做到侧滑删除

Answer 1

lic boolean onTouchEvent(MotionEvent e) {
mVelocityTracker.addMovement(e);

int x = (int) e.getX();
int y = (int) e.getY();
switch (e.getAction()) {
case MotionEvent.ACTION_DOWN:
if (mDeleteBtnState == 0) {
View view = findChildViewUnder(x, y);
if (view == null) {
return false;
}

MyViewHolder viewHolder = (MyViewHolder) getChildViewHolder(view);

mItemLayout = viewHolder.layout;
mPosition = viewHolder.getAdapterPosition();

mDelete = (TextView) mItemLayout.findViewById(R.id.item_delete);
mMaxLength = mDelete.getWidth();
mDelete.setOnClickListener(new OnClickListener() {
@Override
