    <p>I have an activity that I normally want to exist in multiple tasks, so that the [Back] button restores a previous state; however, I also want to use a <a href="http://developer.android.com/reference/android/widget/SearchView.html" rel="noreferrer">SearchView</a> with an existing activity, without pushing a new one onto the task stack (since I want to search what's currently displayed). Here's my problem:</p> <ul> <li>If I set the activity's launch mode to "singleTop", the SearchView works with the current activity, but <a href="http://developer.android.com/reference/android/content/Context.html#startActivity(android.content.Intent)" rel="noreferrer">Context.startActivity</a> does not add new activities to the stack.</li> <li>If I set the activity's launch mode to "standard", <em>startActivity</em> adds new activities to the stack, but SearchView also creates a new (empty) activity, instead of searching the existing one.</li> </ul> <p>I can't find any way make SearchView use intent flags (e.g. <a href="http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_SINGLE_TOP" rel="noreferrer">FLAG_ACTIVITY_SINGLE_TOP</a>. I tried going the other way around, setting launch mode to "singleTop" then adding <a href="http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_NEW_TASK" rel="noreferrer">FLAG_ACTIVITY_NEW_TASK</a> to every intent, but that worked only when launching from a different activity class; when I try to launch a new instance of an activity from its own class, Android didn't respect FLAG_ACTIVITY_NEW_TASK and didn't push a new task onto the stack.</p> <p>Perhaps there's something I can do in <a href="http://developer.android.com/reference/android/app/Activity.html#onNewIntent(android.content.Intent)" rel="noreferrer">Activity.onNewIntent</a> to force the activity to clone itself then.</p> <p>I'm on the verge of giving up on SearchView and just writing my own custom widget, despite that fact that <em>"Beginning in Android 3.0, using the SearchView widget as an item in the action bar is the preferred way to provide search in your app"</em> (<a href="http://developer.android.com/training/search/setup.html" rel="noreferrer">Source</a>) — so far, it seems just too inflexible and non-configurable to be useful in non-trivial cases.</p> <p>Has anyone found a solution to this problem?</p>

    1. COFrom the total lack of responses (and low number of views), I'll guess that this is a non-trivial problem. There is another possible work-around (besides just avoiding SearchView): I could design the singleTop Activity to maintain its own state stack and switch states, then intercept the Back button to simulate moving through the task stack. I have a strong aversion, though, to replacing core OS functionality with simulations — if that's the only option, I'll just decide that Google recommended SearchView prematurely for production use, and will create my own search action component.

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.
