我尝试创建一个游戏来显示图片和角色名称列表。但是当我运行该应用程序时，它一直崩溃并显示错误:

Error inflating class android.support.design.widget.AppBarLayout.

这是日志:

这是activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.user.celebguess.MainActivity">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

</android.support.design.widget.AppBarLayout>

<include layout="@layout/content_main" />
/>

这里还有 styles.xml:

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

这里还有 Java 部分的 main_activity.java:

import android.content.Intent;
import android.content.SharedPreferences;
import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.Toast;

import java.util.ArrayList;
import java.util.Map;

public class MainActivity extends AppCompatActivity {

private GridView gridView;
private SharedPreferences preferences;
private ArrayAdapter<String> names;
private Toast currentToast;
private ImageView img;
private int numberOfChoice;
private ArrayList<String> nameList;
private ArrayList<Integer> photos;
private ArrayList<String> nameForChoose;
private Map<String,Integer> nameMap;
private int currentPicNumber;

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

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

}

@Override
protected void onStart() {
    super.onStart();

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    int orientation = getResources().getConfiguration().orientation;
    if(orientation== Configuration.ORIENTATION_PORTRAIT) {
        getMenuInflater().inflate(R.menu.menu_main, menu);
    }
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();


    if (id == R.id.action_settings) {
        Intent intent = new Intent(this,Settings.class);
        startActivity(intent);
        return true;
    }

    return super.onOptionsItemSelected(item);
}

最佳答案

对于最新版本的android，在build.gradle(app)

implementation 'com.android.support:design:30.0.0'

为了使用，在您的 .xml 中:

<com.google.android.material.appbar.AppBarLayout
