Implementation of Lollipop+ Dialer and Google Maps.

Add to your layout by using the include tag.

<include layout="@layout/widget_search_bar"/>

This overlays the full activity and shows the fragment which you have assigned by using setExpandedContentFragment.

searchViewLayout.setExpandedContentFragment(this, new SearchStaticFragment());

If you want to animate your Toolbar too like the demo gif, you can enable it by using handleToolbarAnimation.

searchViewLayout.handleToolbarAnimation(toolbar);

Setting Background colors for Transition. Default should also work just fine:

// Create Drawable for collapsed state. Default color is android.R.color.transparent
ColorDrawable collapsed = new ColorDrawable(
    ContextCompat.getColor(this, R.color.colorPrimary));

// Create Drawable for expanded state. Default color is #F0F0F0
ColorDrawable expanded = new ColorDrawable(
    ContextCompat.getColor(this, R.color.default_color_expanded));

// Send both colors to searchViewLayout
searchViewLayout.setTransitionDrawables(collapsed, expanded);

Listen to search complete by:

searchViewLayout.setSearchListener(new SearchViewLayout.SearchListener() {
    @Override
    public void onFinished(String searchKeyword) {
        searchViewLayout.collapse();
        Snackbar.make(searchViewLayout, "Search Done - " + searchKeyword, Snackbar.LENGTH_LONG).show();
    }
});

Listen to collapse/expand animation by using setOnToggleAnimationListener. For eg the FAB in demo hides on expanded and shows on collapse.

searchViewLayout.setOnToggleAnimationListener(new SearchViewLayout.OnToggleAnimationListener() {
    @Override
    public void onStart(boolean expanded) {
        if(expanded) {
            fab.hide();
        } else {
            fab.show();
        }
    }

    @Override
    public void onFinish(boolean expanded) { }
});

Listen to search box complete by:

searchViewLayout.setSearchBoxListener(new SearchViewLayout.SearchBoxListener() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }
    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    }
    @Override
    public void afterTextChanged(Editable s) {
    }
});

Setting Hints

If you want to set hints in the view, there are three APIs. setCollapsedHint would come up in the default/collapsed state. setExpandedHint would work for expanded state i.e. after click the view and the keyboard is up. setHint would set both the hints in one go, use this you want to show the same hint in both the states.

searchViewLayout.setCollapsedHint("Collapsed Hint");
searchViewLayout.setExpandedHint("Expanded Hint");
searchViewLayout.setHint("Global Hint");

Setting Icons Use setCollapsedIcon, setExpandedBackIcon, setExpandedSearchIcon to setup icons according to your choice. The argument should be a DrawableRes

1. If you want to add a scrolling widget in your setExpandedContentFragment, add a onTouchListener and disallow the parent intercept by usingv.getParent().requestDisallowInterceptTouchEvent(true);Check out fragments in sample for the implement of ListView, RecyclerView and ScrollView.

   recyclerView.setOnTouchListener(new View.OnTouchListener() {
       // Setting on Touch Listener for handling the touch inside ScrollView
       @Override
       public boolean onTouch(View v, MotionEvent event) {
           // Disallow the touch request for parent scroll on touch of child view
           v.getParent().requestDisallowInterceptTouchEvent(true);
           return false;
       }
   });

2. The default height of the view is 120dp which is also present in the dimens.xml file as

   <dimen name="search_view_layout_approx_height">120dp</dimen>

   You can use it for adding margin on top of your main content layout.
