recyclerview的setAdapter（）导致崩溃，说相对布局中不存在循环依赖

Question

我正在使用一个简单的活动向Recyclerview显示一些数据，但是当我填充适配器并调用setAdapter时，我的应用程序崩溃时出现此错误，这只发生在Marshmallow和apis下面。它在Nougat和Oreo工作正常。

是的我知道相对布局中的循环引用。但是我在xml文件中看不到任何循环引用。它只包含一个Recyclerview。

我的主要java类

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);
}
}

我现在已经坚持了2天，仍然无法找到解决方案。

Answer 1

解决了它。这行是我的适配器xml android中的问题：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"/>

不知何故，它没有在Nougat和上面的API中被检测到，但是在Marshmallow上面，它被系统检测到，因此导致崩溃。删除此行解决了崩溃问题。
