Implementation code of recyclerview drag and delete function in Android

No more nonsense. Let's show the effect.

This is the GridView master file implementation.

The code is not difficult to understand, but a lot of initialization things are set in the activity. Recyclerview initialization, setlayoutmanager, additemdecoration, sethasfixedsize, itemtouchhelper, addonitemtouchlistener, setadapter. The key code of drag effect is itemtouchhelper. Startdrag (viewholder). Everything else revolves around it.

Then look at the settings.

DataManager

Dividergriitemdecoration draws the sideline of the item

Recycleradapter adapter to establish connection with UI

Onrecycleritemclicklistener, click the event. We borrow gesture tool class gesturedetectorcompat to operate

RecyitemtouchhelperCallback

The following are the related settings of list

Similarly, listview is also an initialization setting.
