    <p>Is there a reliable way to lock screen orientation on all Android devices? The code below works for my Nexus S and other phones, but for some reason ROTATION_90 corresponds to SCREEN_ORIENTATION_REVERSE_PORTRAIT on the Xoom. </p> <p>Is there any way to reliably map rotation to orientation?</p> <pre><code>private void lockScreenOrientation() { if (!mScreenOrientationLocked) { final int orientation = getResources().getConfiguration().orientation; final int rotation = getWindowManager().getDefaultDisplay().getOrientation(); if (rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_90) { if (orientation == Configuration.ORIENTATION_PORTRAIT) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); } else if (orientation == Configuration.ORIENTATION_LANDSCAPE) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); } } else if (rotation == Surface.ROTATION_180 || rotation == Surface.ROTATION_270) { if (orientation == Configuration.ORIENTATION_PORTRAIT) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT); } else if (orientation == Configuration.ORIENTATION_LANDSCAPE) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE); } } mScreenOrientationLocked = true; } } private void unlockScreenOrientation() { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR); mScreenOrientationLocked = false; } </code></pre> <p>EDIT: This code is meant to get the current orientation and lock it. The orientation is locked temporarily, and then released to the user.</p>

    1. COWow, that's a lot of code just to lock orientation. I had one screen that I needed to lock orientation on, and all I needed was `setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE)`

    2. COThe code locks to the current orientation, not some arbitrary orientation. The code works fine for everything except Honeycomb portrait. I could hardcode that case in there, but it's not a permanent solution, because device manufacturers can specify any rotation/orientation combination they desire.

    3. COI'm facing the exact same problem right now, and wrote almost the exact same thing as your code sample and it doesn't work on my Galaxy 10.1. Have you made any progress since posting this?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
