    <p>i m just wondering about some android ui aspects where i need some advices! Might be, that my idea so far is not the best...</p> <p>Basically I m working on an app, which plays streams in a player (<strong>main screen</strong>). The user can select streams in a second screen (<strong>tabbar screen</strong>), where he can switch between three different lists, each one is in one of the tabs and each tabbarclick starts a new activity (i m not using an <code>ActionBar</code> or sth, I just created an own UI element which consist of three icons, current one selected and the other two starting a new Activity): </p> <ul> <li><p><code>ListViewActivity1</code>: dynamically created ViewFlipper with nested ListViews (f.e. country->state->city..) from a database </p></li> <li><p><code>ListViewActivity2</code>: simple ListView with favorits from <code>ListViewActivity1</code></p></li> <li><code>ListViewActivity3</code>: simple ListView with UserGenerated content</li> </ul> <p>So far it s working great but I m starting to struggle... Everytime the user enters the <strong>tabbar screen</strong> again, I want him to be exactly at the last <code>ListView</code> where he was. So basically I m looking for a way to store the different screens if the user leaves them. I came across <code>onSaveInstanceState(Bundle savedInstanceState)</code>, but this doesn't really fit my needs. The <code>ListViewActivity 1</code> is a really complex list with up to six levels sometimes, which I really don't want to transport in a <code>savedInstanceState</code>! Is there another way?</p> <p>Actually if I go back in the <code>BackStack</code>, this really saves the different states like I want it to. So it is possible, I just don't find anything like this..</p> <p>So, <strong>question 1</strong>: Is there a way to save a view like the <code>BackStack</code> does?</p> <p><strong>question 2</strong>: Is this whole idea of ui-implementation a good solution to set up an app? </p> <p>thanks for any input!</p>

    1. COso far, I have to admit: no, there s no way... I actually ended up to save all needed states in SharedPreferences, and redraw every view after restart... wasn't thaat hard, but still it would been nicer, if your simple just can use sth. like " getLastViewStateFromBackStack() "...

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.
