How to refresh tableview with new set of updated data without losing the scrolled horizontal position #342

Closed ashish-d-hh closed 3 years ago

ashish-d-hh commented 3 years ago

I am looking for a way, where I update some value in the cell of a column, then I hit an API to save that change, and then reload data from API and then fill the table view again with it.

Currently what happens is if I am at column 30th, then on refreshing data I am taken back to 0th column

@evrencoskun 

tableview.tableViewListener = clickListener
        tableview.setAdapter(mTableAdapter);
        tableview.setIgnoreSelectionColors(true);
        tableview.rowHeaderRecyclerView.setBackgroundColor(Color.BLACK)
        mTableAdapter?.setAllItems(
            mSelectedColumnHeaderList, mRowHeaderLotDetailsList,
            mCellList
        )
        mTableAdapter.notifyDataSetChanged()

Solved it using following code:

private lateinit var preferencesHandler: PreferencesHandler
    private lateinit var preferencesOfPosition: Preferences

To save current position of scroll, use:

preferencesOfPosition= preferencesHandler.savePreferences()

To revert back to the save scroll, use

preferencesHandler.loadPreferences(preferencesOfPosition)

Thanks @evrencoskun for this great feature. 👍
