implement Globe-Weis File Folder in android

i want to implement Globe-Weis File Folder like picture below which by clicking on green button it scrolling smoothly up and by clicking on the green button again ,the folder page scrolling down smoothly.

what i try so far was putting three scrollView in a frameLayout , and to open and close it

 if (!underIsOpen) {
     ObjectAnimator
     .ofInt(sv_Under, "scrollY",
     findViewById(R.id.ll_under_botton).getTop())
     .setDuration(1000).start();
     underIsOpen = true;
     } else {

     ObjectAnimator
     .ofInt(sv_Under, "scrollY",
     findViewById(R.id.ll_under_s_part).getTop())
     .setDuration(1000).start();
     underIsOpen = false;

     }

but it just work on the scrollView which is on top

my code is:

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test3);
    ll_under_s_part = (LinearLayout) findViewById(R.id.ll_under_s_part);
     sv_Under = (ScrollView) findViewById(R.id.scrollView1);
     sv_Mid = (ScrollView) findViewById(R.id.scrollView2);
     sv_Top = (ScrollView) findViewById(R.id.scrollView3);

}


public void onClick_under_left(View v) {
    Toast.makeText(getApplicationContext(), "under layout",
            Toast.LENGTH_SHORT).show();


     if (!underIsOpen) {
     ObjectAnimator
     .ofInt(sv_Under, "scrollY",
     findViewById(R.id.ll_under_botton).getTop())
     .setDuration(1000).start();
     underIsOpen = true;
     } else {

     ObjectAnimator
     .ofInt(sv_Under, "scrollY",
     findViewById(R.id.ll_under_s_part).getTop())
     .setDuration(1000).start();
     underIsOpen = false;

     }
}

public void onClick_mid_left(View v) {
    Toast.makeText(getApplicationContext(), "mid layout",
            Toast.LENGTH_SHORT).show();

}

public void onClick_top_left(View v) {

    Toast.makeText(getApplicationContext(), "top layout",
            Toast.LENGTH_SHORT).show();

     if (!topIsOpen) {
     ObjectAnimator
     .ofInt(sv_Top, "scrollY",
     findViewById(R.id.ll_top_botton).getTop())
     .setDuration(1000).start();
     topIsOpen = true;
     } else {

     ObjectAnimator
     .ofInt(sv_Top, "scrollY",
     findViewById(R.id.ll_top_s_part).getTop())
     .setDuration(1000).start();
     topIsOpen = false;

     }
}

            </LinearLayout>
        </ScrollView>
    </FrameLayout>
</LinearLayout>

the second way i tried was using animation but no success to result i am looking for :

    public void SlideUP(View view, Context context) {
    view.startAnimation(AnimationUtils.loadAnimation(context,
            R.anim.slid_up));
}

public void SlideDown(View view, Context context) {
    view.startAnimation(AnimationUtils.loadAnimation(context,
            R.anim.slid_down));
}

any other way that i can implement this?

I don't think adding so may layout on a single screen with scrollbars is a good idea, you can apply simple frame layouts and list them accordingly and when clicking on any of the desired folder icons just animate it towards top, and it will also show the content of the folder.

you could customize this library to do that, I have done a similar kind of app and applied the same library with my custom changes.
