[Android] Textswitcher--What do you do?

Textswitcher 's Java Doc describes itself in this way:

Specialized Viewswitcher that contains only children of type TextView. A textswitcher is useful to animate a label on screen. Whenever SetText (charsequence) is called, Textswitcher animates the current text out and animates the new text in .

So, Textswitcher:
-There is a TextView child View
-When text is updated, the old text fades out and new text fades in, rendering the animated effect of smooth transitions

How to use Textswitcher step 1th: Add Textswitcher controls in Layout

    <TextSwitcher        android:id="@+id/ts"        android:layout_width="wrap_content"        android:layout_height="0dp"        android:layout_marginTop="20dp"        android:layout_weight="1" >    </TextSwitcher>

2nd step: Set up a factory for the Textswitcher control (for production views)

        mTs.setFactory(new TextSwitcher.ViewFactory() {            @Override            publicmakeView() {                final TextView tv = (TextView) LayoutInflater.from(                        null);                return tv;            }        });

3rd step: Setting the Fade animation

        mTs.setInAnimation(AnimationUtils.loadAnimation(                getApplicationContext(), android.R.anim.fade_in));        mTs.setOutAnimation(AnimationUtils.loadAnimation(                getApplicationContext(), android.R.anim.fade_out));

After that, the mTs.setText(txt) following effect is performed when the text is toggled:
