Android Studio navigation drawer like Gmail app
<p>We're making an android app, and there is something we want to add.
Which is the effect the Gmail app has.</p>

<p>You can choose which account you want to view (and the rest of the app will behave accordingly).</p>

<p><strong>EDIT:</strong></p>

<p>I now already have a (working) navigation bar, but the things I want are the round icons in the header. I want someone to be able to choose the user they are viewing.</p>
