我一直在开发应用程序,我使用模拟器作为测试人员。当应用程序完成后,我在Android 5和4中测试了它,但Actionbar就不会出现了。模拟器的平台是5.1.1作为我测试它的第一部手机。我脑子里唯一想到的是可能包含错误的清单文件,这里是:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.flexenergy.swapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="22" />
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/myActionBarTheme" >
<activity
android:name="com.flexenergy.swapp.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>
另一件事,我在左侧有一个可绘制的列表视图菜单,按下操作栏(未显示),但如果我从左向右滑动手指,它会出现。
唯一的styles.xml如下(我将它放在values-v22,values-v11等中):
<?xml version="1.0" encoding="utf-8"?>
