POAndroid SensorManager.getOrientation before event triggered
text
Body
copied!<p>I am working on an app for a tablet where the tablet will be in a stand which rotates about a given point. That means <em>very little</em> movement from the tablet when the app is first opened. The app will display various things depending on the rotation of the tablet in the stand. What I cannot seem to find how to do no matter how hard I search is to get the initial orientation in degrees or radians which is comparable to the value of <code>OrientationEventListener.onOrientationChanged(int orientation)</code>. I have an OrientationEventListener configured and my idea was that during the default Activities <code>onCreate</code> method, I would manually call the OrientationEventListener with an updated value.</p> <p>Demo code that doesn't run by itself, but illustrates the point:</p> <pre><code>//No problems at this point in the code, the OrientationManager class //which extends OrientationEventListener properly receives onOrientationChanged //notices OrientationEventListener orientationEventListener; orientationEventListener = new OrientationManager( this, SensorManager.SENSOR_DELAY_NORMAL ); orientationEventListener.enable(); //Here's where the problem is... need to get the current orientation //and "initialize" the OrientationEventListener float[] coords = new float[3]; float[] rotation = new float[16]; SensorManager.getOrientation(rotation, coords); //Test for correct coords values (logs "0.0, -0.0, -0.0") Log.d("DEBUG", Float.toString(coords[0]) + ", " + Float.toString(coords[1]) + ", " + Float.toString(coords[2]) ); //Goal is to be able to call orientationEventListener.onOrientationChanged(??) //with the value that would be sent if the event was called naturally </code></pre> <p>Now, did I submit a question already asked and answered? I've looked at so many SO posts and haven't gotten anywhere.</p>
