Why Recyclerview start scrolling up/down from half of the list?

Actually, I am updating "RecylerView" list adapter based on filter data list. When I update adapter data updated successfully but Scrolling start from half of adapter list. Does anyone face problem like this before?

Things i have already tried - Put Recyclerview inside RelativeLayout - Set Recyclerview height to wrap_content - Use requestLayout method

You can listen to adapter updates and scroll your RecyclerView to starting position when changes are detected.

If you're using Java:

//Initializing your adapter 
MyAdapter myAdapter = new MyAdapter(...);

//Listening to adapter updates
myAdapter.registerAdapterDataObserver(new RecyclerView.AdapterDataObserver() {
    @Override
    public void onChanged() {

        //Scrolling to starting position
        recyclerView.getLayoutManager().scrollToPosition(0);
    }
});

//Setting your adapter on your RecyclerView
myRecyclerView.setAdapter(myAdapter);

...

If you're using Kotlin:

//Initializing your adapter 
var myAdapter = MyAdapter(...)

//Listening to adapter updates
myAdapter.registerAdapterDataObserver(object : 
        RecyclerView.AdapterDataObserver() {
    override fun onChanged() {

        //Scrolling to starting position
        myRecyclerView.layoutManager.scrollToPosition(0)
    }
})

//Setting your adapter on your RecyclerView
myRecyclerView.adapter = myAdapter

...

Hope it helps! =)
