Question

在下面的行中抛出错误

setContentView(R.layout.activity_main);

android.view.InflateException：二进制XML文件行＃9：错误膨胀类android.support.v7.app.widget.RecycleView

我错过了什么？

代码

MainActivity.java

package com.example.xxx.yyyy;

import android.database.sqlite.SQLiteException;
//import android.support.v7.app.AlertController;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.util.Log;

import java.io.IOException;
import java.sql.SQLException;
import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

private final static String TAG = "MainActivity";
DBHandler dbHandler = null;

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

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?>

<android.support.v7.app.widget.RecycleView
    android:id="@+id/esp_menu"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</android.support.v7.app.widget.RecycleView>

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello World!"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

xml中的错误。 RecycleView而不是RecyclerView（丢失了Recycler末尾的r字母）
