ListView and ListActivity, with Layout Animation

In the article Layout Animation, list_layout_controller is included in layout, main.xml. In the last article ListView and ListActivity, ListView is implemented as ListActivity, without XML file for layout. How can apply the LayoutAnimationController.

In this article, the same visual effect of Layout Animation will be applied on ListView and ListActivity.



- Follow the last exercise, ListView and ListActivity.

- Same as Layout Animation, create the folder /res/anim and add the files list_layout_controller.xml and scale.xml.

list_layout_controller.xml

<layoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"

 android:delay="50%"

 android:animation="@anim/scale" />

scale.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"

android:interpolator="@android:anim/accelerate_interpolator">

<scale

 android:fromXScale="0.1"

 android:toXScale="1"

 android:fromYScale="0.1"

 android:toYScale="1.0"

 android:duration="2000"

 android:pivotX="10%"

 android:pivotY="10%"

 android:startOffset="100" />

</set>

- Modify AndroidListActivity.java to add two lines of code in onCreate()

 @Override

 protected void onCreate(Bundle savedInstanceState) {

  // TODO Auto-generated method stub

  super.onCreate(savedInstanceState);

  

  setListAdapter(new ArrayAdapter<String>(this,

            android.R.layout.simple_list_item_1, COUNTRIES));

  getListView().setTextFilterEnabled(true);

  

  LayoutAnimationController controller 

   = AnimationUtils.loadLayoutAnimation(

     this, R.anim.list_layout_controller);

  getListView().setLayoutAnimation(controller);


 }

That's!
