错误：'；未能找到样式'；协调人外展风格'；在当前主题中'；在Android研究3.1.3中

我刚开始使用Android Studio，一直在尝试使用

导航抽屉

布局，但我似乎无法避免错误在当前主题中找不到样式

协调人或超出样式

。我尝试在

style.xml

中的应用程序主题下添加

@style/Widget.Design.CoordinatorLayout

，同时将

实现'com.android.support:appcompat-v7:28.0.0-alpha3'

更改为

alpha1

。这两个都不适合我。下面是代码

MainActivity.java

package com.example.divya.niluv1;

import android.os.Bundle;

import android.support.design.widget.Snackbar;

import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.addDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);
    }

    @Override
    public void onBackPressed() {
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }

    @Override

        // Inflate the menu; this adds items to the action bar if it is present.

        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;

        <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" />

</resources>

任何帮助都将不胜感激。谢谢。

像这样试试

implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'

这项工作对我来说，我也有同样的错误

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.support:design:28.0.0-alpha1'}

编辑： 在这个路径：app>res>layout中，您找到了2个xml，被调用的activity_main在第二行中有：

android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

最后，这个

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

因此，您需要做的是删除它们并粘贴以下内容：

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

---

Lorenzo的答案是可行的，但我个人发现它稍微改变了我的布局，但在values/styles.xml中添加以下内容对我来说是可行的

<style name="AppTheme.NoActionBar">
<item name="coordinatorLayoutStyle">@style/Widget.Design.CoordinatorLayout</item>
</style>

@样式/Widget.Design.CoordinatorLayout

我也有同样的问题。问题在于所使用的编译器版本。我用28换27

此外，我还将appcompat-v7:28.0.0-alpha1替换为appcompat-v7:27.1.1

这是我的工作

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.test.hello"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

我必须点击再试一次，我不知道为什么，但它的工作之后。关于这个主题的问题是存在的，但不是真正的“问题”，只是有一点它确实起了作用。您是对的，它确实会带来渲染问题，但运行良好。谢谢
