Android 禁止响应屏幕翻转

app安装到手机后，翻转屏幕，页面可能出现变型，弹出框消失等问题，禁止屏幕翻转：

要在androidmanifest.xml 中加入 android:screenOrientation="portrait"

需要在application 标签属性加入，也需要在所有activity标签属性加入

<application
        android:allowBackup="true"
        android:icon="@drawable/ui"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" 
      android:screenOrientation="portrait">
        <activity
            android:name="com.pccw.barcodescanner.MainActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar" 
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            intent-filter>
        activity>
        <activity
            android:name="com.pccw.barcodescanner.ServiceConfigActivity"
            android:label="@string/main_config"
            android:theme="@android:style/Theme.NoTitleBar"
         android:screenOrientation="portrait" >
        activity>
        <activity
            android:name="com.pccw.barcodescanner.OnlineActivity"
            android:label="@string/main_Rbonline"
            android:theme="@android:style/Theme.NoTitleBar"
         android:screenOrientation="portrait" >
        activity>
