Update an activity after use of optionsMenu
<p>I have an app with 5 activities. All these activities have settings that can be modified using the menu-button (optionsmenu) and selecting 'Settings'. This will open a dialog where all settings shown and where modification is possible. </p>

<p>When I close this settings-dialog by press the 'ok'-button, I want the activity that called optionsmenu to update its view.</p>

<p>The optionsmenu is activited like this in all activities:</p>

<pre><code>    @Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.firstactivity_options_menu, menu);      
    return true;
}
</code></pre>

<p>And an example of onOptionsItemSelected follows...</p>

<pre><code>    @Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == R.id.settings) {
        class.settingsDialog(this);         
    } else if (item.getItemId() == R.id.about) {
        try {
            alertDialog(getResources().getString(R.string.settings_about), getAssets().open("about"), this);
        } catch (IOException e) {
        }
    }   
    return true;
}
</code></pre>

<p>My problem is updating an activities view after I've had a match for R.id.settings. Is this possible? And if so, please give me some pointers...</p>
