My App has a map fragment . And on clicking marker , an slide up animation shows from bottom to half of screen . And it slide down on clicking marker again .
I want : Slide up menu should be clickable or drag gable so that it can move to top of screen . to be more clear , i mean either on clicking or dragging this slide up menu which is on half of screen , should go to top of screen .
So far i done : On clicking marker, call the slide up animation to half of screen. : 
Animation code : slide_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<objectAnimator
android:interpolator="@android:anim/accelerate_decelerate_interpolator"

</set>
slide_down.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

</set>
The code in Activity which calling this Animation on Marker click :
public void toggleList() {
Fragment f = getFragmentManager().findFragmentByTag(LIST_FRAGMENT_TAG);
if (f != null) {
getFragmentManager().popBackStack();
} else {
getFragmentManager()
.beginTransaction()
.setCustomAnimations(R.anim.slide_up,
R.anim.slide_down,
R.anim.slide_up,
R.anim.slide_down)
.add(R.id.list_fragment_container, BaseMapSlidingFragment
.instantiate(this, BaseMapSlidingFragment.class.getName()),
LIST_FRAGMENT_TAG
)
.addToBackStack(null).commit();
googleMap.getUiSettings().setAllGesturesEnabled(false);
if(animCheck == false){
animCheck = true;
}else
{
animCheck= false;
}
}}
menu_Sliding.up.xml
