Error: Getting AppCompatActivity is not compatible with android:Theme.Material

Question

我正在尝试使用 Material 主题向我的应用添加导航抽屉。关注 this tutorial here to start.

输出应该类似于 this GIF:

看起来 AppCompatActivity 与 android:Theme.Material 不兼容，不明白为什么？

我的res/styles.xml：

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
</style>

<!-- your theme inherits from the material theme -->
<style name="MaterialTheme" parent="android:Theme.Material">
    <!-- theme customizations -->
</style>

我的Activity代码，简单地扩展了AppCompatActivity:

public class MainActivity extends AppCompatActivity {


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

现在，我的清单，不是我要使用的：MaterialTheme:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xxxx.xxxxxxxx.xxx" >

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/MaterialTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

这是我得到的错误：

Looks like AppCompatActivity is not compatible with android:Theme.Material, dont understand why?

appcompat-v7 操作栏向后移植需要使用 Theme.AppCompat 及其子主题（例如，Theme.AppCompat.Light）。这就是那个图书馆的本质。您的选择是：

不使用AppCompatActivity而使用原生操作栏，或者
不使用 Theme.Material 而是使用 Theme.AppCompat
