Application enables orientation change button is status bar

问题

I use nativescript in my project, also I always disable toggler on status bar menu on my Galaxy Alpha that allows orientation change. When I open my app the button status is set to enabled. How to remove this behaviour?

Here is an example of what button i mean, on this screen it called auto rotation. https://lh4.ggpht.com/LuZ3y6wD4aUBdBvZ8Wxf73BpWdfbfNdxOVcHMuRVgRcyz-dl9rRNUwtpx-L9uPlgJdc=h900

Here is my manifest file:

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

          android:versionName="1.0">

    <supports-screens
            android:smallScreens="true"
            android:normalScreens="true"
            android:largeScreens="true"
            android:xlargeScreens="true"/>

    <uses-sdk
            android:minSdkVersion="17"
            android:targetSdkVersion="25"/>

    <application
            android:name="com.tns.NativeScriptApplication"
            android:allowBackup="true"
            android:icon="@drawable/icon"
            android:label="@string/app_name"
            android:theme="@style/AppTheme">

        <activity
                android:name="com.tns.NativeScriptActivity"
                android:label="@string/title_activity_kimera"
                android:configChanges="keyboardHidden|screenSize"
                android:theme="@style/LaunchScreenTheme"
                android:screenOrientation="portrait">

            <meta-data android:name="SET_THEME_ON_LAUNCH" android:resource="@style/AppTheme"/>

            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <activity android:name="com.tns.ErrorReportActivity"/>
    </application>
</manifest>

UPDATE Ok, I found possible reason but can't find it in nativescript code.

回答1:

Have you tried this out, I used it in my project and it works fine

npm nativescript-screen-orientation

回答2:

This should do the trick for you:

import android.provider.Settings;
public static void setAutoOrientationEnabled(Context context, boolean enabled)
{
      Settings.System.putInt( context.getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, enabled ? 1 : 0);
}

Add permission to the AndroidManifest.xml

I had the excact same problem. What I ended up with was using an OrientationListener to detect when the user had actually tilted the phone to landscape and then setting the orientation to SCREEN_ORIENTATION_SENSOR.

OrientationEventListener orientationEventListener = new OrientationEventListener(getActivity()) {
@Override
public void onOrientationChanged(int orientation) {
    int epsilon = 10;
    int leftLandscape = 90;
    int rightLandscape = 270;
    if(epsilonCheck(orientation, leftLandscape, epsilon) ||
       epsilonCheck(orientation, rightLandscape, epsilon)){
            getMainActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
        }
    }

    private boolean epsilonCheck(int a, int b, int epsilon) {
        return a > b - epsilon && a < b + epsilon;
    }
};
orientationEventListener.enable();

You would also need to add checks for portrait , because you described needing that in your original post.
