Tutorial :Using Views in a tabbed application


Alright, so I have an application that has a tabbed interface. What I would like to know is how I can change the currently active View in the tab, and then when I'm done with that View, go back the the original View, exactly as it was.


You may also want to use a ViewFlipper, defined in xml.

<ViewFlipper android:id="@+id/ScreenSwitch"      android:layout_width="fill_parent"      android:layout_height="fill_parent">      <element A>      <element B>      <element C>  </ViewFlipper>  

Usage is simple, just find the ViewFlipper object throught findViewById() and request changing:

viewFlipper.setDisplayedChild( idOfViewToSet );  

It's then completely up to you, how do you build "tabs".


For creating the view, what you probably want is something like this:

import android.view.View;  import android.widget.TabHost;    public class MyViewController implements TabHost.TabContentFactory  {      private View myRootView;        @Override      public View createTabContent(String tag)      {          if (myRootView == null)          {              // TODO: Create your view here by...              //       1) Constructing it yourself              //       2) Inflating a layout.xml with LayoutInflater (better)              myRootView = new View(context);          }          return myRootView;      }  }  

As for changing tabs programmatically, it is as simple as calling setCurrentTab() on your TabHost object.
