    <p>I have a MenuItem from SherlockActionBar in my Menu that has a checkbox, but when I rotate the device, the checkbox is still active, but the icon on the right of the label is unchecked.</p> <p>What I want to achieve is to show that box checked again after rotating the device.</p> <p>So far I've been trying to fix it with SharedPreferences, flags, storing "Menu" (from onCreateOptionsMenu) to a variable and looking for the id, onPrepareOptionsMenu, but nothing is doing what I want.</p> <p>What I'm doing right now is storing a status flag of the MenuItem on "onOptionsItemSelected", then on "onPrepareOptionsMenu" check the value of the flag and setting the check... But that is causing even more trouble.</p> <p>I no have a clue of what to do. :(</p> <p>The code:</p> <pre><code>private boolean lockFlag; ... @Override public boolean onCreateOptionsMenu(Menu menu) { this.menu = menu; getSupportMenuInflater().inflate(R.menu.activity_main, menu); return super.onCreateOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.menu_lock: if (item.isChecked()) { item.setChecked(false); lockFlag = false; } else { item.setChecked(true); lockFlag = true; } return true; default: return super.onOptionsItemSelected(item); } } @Override public boolean onPrepareOptionsMenu(Menu menu) { super.onPrepareOptionsMenu(menu); if (lockFlag) { menu.findItem(R.id.menu_lock).setChecked(true); } else { menu.findItem(R.id.menu_lock).setChecked(false); } return true; } private void savePrefs() { getSharedPreferences("LOCKBARS", MODE_PRIVATE).edit().putBoolean("lockbars", lockFlag).commit(); } private void loadPrefs() { this.lockFlag = getSharedPreferences("LOCKBARS", MODE_PRIVATE).getBoolean("lockbars", false); } </code></pre> <p>EDIT: Those are the kind of checkbox that I'm using, I'm not setting manually any icon.</p> <p><img src="https://i.stack.imgur.com/Gdo1S.png" alt="enter image description here"> <img src="https://i.stack.imgur.com/nF70T.png" alt="enter image description here"></p> <p>EDIT2:</p> <p>OK, looks like that <code>android:configChanges="orientation|screenSize"</code> does the trick, but it stops using the layout for landscape mode and uses the defalut one instead. And <code>android:configChanges="orientation"</code> without "screenSize" does nothing.</p> <p>Edit3:</p> <p>Shameless auto bump. I'm still stuck. :(</p>

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.
