onConfigurationChanged 不适用于 API17

onConfigurationChanged is not working for API17

如果 table 从纵向倾斜到横向或反之亦然,我想触发一些东西。
然而 onConfigurationChanged 永远不会被触发。 我读过几年前堆栈溢出粉丝提出的几个问题,但 none 正在工作。
例如,在 Android 中添加 android:configChanges="orientation|screenSize"。 下面是 AndroidManifest.xml、应用和调试日志,
谢谢

您应该将以下字符串放在 "activity" 标记之间,而不是 "application" 之间,尝试像下面这样使用它:

<application
    android:allowBackup="true"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <activity
        android:name=".MainActivity"
        android:configChanges="screenSize|keyboardHidden|orientation" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
