Question

My thinking is a layout with a progressBar( determinate ) will be shown for 5 second when i open my app. After 5sec this layout will be replaced by another layout containing some buttons.
How to do that. Plz help me…

You can define all of the two layouts properties inside one layout under ViewFlipper

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/lah"
    >
    <ViewFlipper 
        android:id="@+id/flipper"
        android:layout_height="fill_parent"
        android:layout_width="fill_parent" 
        >

       <LinearLayout 
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:id="@+id/first_layout">
         .
         .

         .

       </LinearLayout> 

       <LinearLayout 
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:id="@+id/second_layout">
         .
         .

         .

       </LinearLayout> 

   </ViewFlipper 
</LinearLayout> 

Then in your java program create a ViewFlipper object.

    ViewFlipper vf = (ViewFlipper) findViewById( R.id.flipper);

And call

    vf.showNext();

You can also apply animation that seems switching layouts from right to left. Thanks…

    vf.setInAnimation(AnimationUtils.loadAnimation( getApplicationContext(), R.anim.right_in ));
    vf.setOutAnimation( AnimationUtils.loadAnimation( getApplicationContext(), R.anim.left_out ));
    vf.showNext();
