setAdapter() of recyclerview causes crash saying circular dependency cannot exist in Relative Layout

Question

I am using a simple activity to show recyclerview with some data but when i populate adapter and call setAdapter on it, my app crashes with this error and this happens only in Marshmallow and below apis. It is working fine in Nougat and Oreo.

Yes I know what circular references are in relative layout. However i cannot see any circular references in my xml file. It contains only a recyclerview.

My main java class

package com.example.aamishkhan.tablayoutandbottomnavigationviewsample;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.DefaultItemAnimator;
import android.support.v7.widget.DividerItemDecoration;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

import java.util.ArrayList;

public class RecyclerViewActivity extends AppCompatActivity {

private RecyclerView recyclerView;
private StocksRvAdapter adapter;
private ArrayList<StocksBean> stocksIndicesBeanList = new ArrayList<>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_recycler_view);

    recyclerView = findViewById(R.id.recycler);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    recyclerView.setItemAnimator(new DefaultItemAnimator());
    recyclerView.addItemDecoration(new DividerItemDecoration(this, LinearLayoutManager.VERTICAL));
    recyclerView.setHasFixedSize(true);

    for (int i = 0; i < 10; i++) {
        StocksBean stocksBean = new StocksBean("First", "REG", "1.0", "2.0", "3.0",
                "50", "50.0", "60", "abc", "false",
                "100", "110", "0950", "5000", "20",
                "0", "50.0", "80.0", "open", "10000",
                "4000", "12052017", "80");

        stocksIndicesBeanList.add(stocksBean);
    }

    adapter = new StocksRvAdapter(this, stocksIndicesBeanList, "indexes");
    recyclerView.setAdapter(adapter);
}
}

I have been stuck on it for 2 days now and still can't figure out the solution.

Answer 1

Solved it. This line was the problem in my adapter xml android:layout_toRightOf="@+id/mainrl"

<View
android:layout_width="2dp"
android:layout_height="wrap_content"
android:id="@+id/separatorend"
android:background="#ebebeb"
android:layout_toRightOf="@+id/mainrl"
android:layout_alignBottom="@+id/mainseparator"
android:layout_toStartOf="@+id/imagesrl"
android:layout_toLeftOf="@+id/imagesrl"/>

Somehow it was not being detected in Nougat and above API's but on Marshmallow and below it was being detected by the system so making the crash. Removing this line solved the crash.
