应用程序启用方向更改按钮是状态栏 [英] Application enables orientation change button is status bar

问题描述

我在我的项目中使用nativescript，而且我总是在Galaxy Alpha的状态栏菜单上禁用切换器，以允许更改方向.当我打开我的应用程序时，按钮状态设置为启用.如何删除这种行为?

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?

这里是按钮含义的示例，在此屏幕上称为自动旋转. https://lh4.ggpht.com/LuZ3y6wD4aUBdBvZ8Wxf73BpWdfbfNdxOVcHMuRVgRcyz-dl9rRNUwtpx-L9uPlgJdc=h900

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

这是我的清单文件:

                android:theme="@style/LaunchScreenTheme"
                android:screenOrientation="portrait">

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

            <intent-filter>

        </activity>
        <activity android:name="com.tns.ErrorReportActivity"/>
    </application>
</manifest>

更新 好的，我发现了原因，但在本机脚本代码中找不到它.

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

推荐答案

我遇到了同样的问题.最后，我使用了OrientationListener来检测用户何时将手机实际倾斜到横向，然后将方向设置为SCREEN_ORIENTATION_SENSOR.

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();

您还需要添加肖像检查，因为您在原始帖子中描述了需要.

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