CodePudding user response：

I solved my problem. The problem happens in MainActivity, it is caused by RecyclerView Data that has been modified in different thread. checking all data access and wrapping LinearLayoutManager would be considered as a solution.

I wrote the code gave by @sakiM at first answer: RecyclerView and java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder in Samsung devices Here is the code:

public class WrapContentLinearLayoutManager extends LinearLayoutManager {
    public WrapContentLinearLayoutManager(Context context) {
        super(context);
    }

    public WrapContentLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

    public WrapContentLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
        try {
            super.onLayoutChildren(recycler, state);
        } catch (IndexOutOfBoundsException e) {
            Log.e("TAG", "meet a IOOBE in RecyclerView");
        }
    }
}

Then i matched my RecyclerView to WrapContentLinearLayoutManager

Here is the code:

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view); recyclerView.setLayoutManager(new WrapContentLinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));

Thank you all, have a nice day
