android - BottomSheet with ViewPager and Fragments? -

i want view in older version of streetview.

i have tried bottomsheetbehavior viewpager, dynamic height of fragments not working properly.

using customviewpager can set height of fragment

public class custompager extends viewpager {  private view mcurrentview;  public custompager(context context) {     super(context); }  public custompager(context context, attributeset attrs) {     super(context, attrs); }  @override public void onmeasure(int widthmeasurespec, int heightmeasurespec) {     if (mcurrentview == null) {         super.onmeasure(widthmeasurespec, heightmeasurespec);         return;     }     int height = 0;     mcurrentview.measure(widthmeasurespec, measurespec.makemeasurespec(0, measurespec.unspecified));     int h = mcurrentview.getmeasuredheight();     if (h > height) height = h;     heightmeasurespec = measurespec.makemeasurespec(height, measurespec.exactly);      super.onmeasure(widthmeasurespec, heightmeasurespec); }  public void measurecurrentview(view currentview) {     mcurrentview = currentview;     requestlayout(); }  public int measurefragment(view view) {     if (view == null)         return 0;      view.measure(0, 0);     return view.getmeasuredheight(); }} 

and add in adapter add these lines too

private int mcurrentposition = -1;      @override     public void setprimaryitem(viewgroup container, int position, object object) {         super.setprimaryitem(container, position, object);         if (position != mcurrentposition) {             fragment fragment = (fragment) object;             custompager pager = (custompager) container;             if (fragment != null && fragment.getview() != null) {                 mcurrentposition = position;                 pager.measurecurrentview(fragment.getview());             }         }     }
