根据视频说明,我无法在全屏模式下运行Android应用.当它试图运行时,应用程序崩溃并出现错误.

"You need to use a Theme.AppCompat theme (or descendant) with this activity

清单文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.djsg38.hikerswatch">

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<application

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

</manifest>

样式文件

<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>

可能有用的部分MainActivity

public class MainActivity extends AppCompatActivity {
