Integration

1) Add as a dependency to your build.gradle:

dependencies {
    compile 'com.melnykov:floatingactionbutton:1.3.0'
}

2) Add the com.melnykov.fab.FloatingActionButton to your layout XML file. The button should be placed in the bottom right corner of the screen. The width and height of the floating action button are hardcoded to 56dp for the normal and 40dp for the mini button as specified in the guidelines.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             xmlns:fab="http://schemas.android.com/apk/res-auto"
             android:layout_width="match_parent"
             android:layout_height="match_parent">

    <ListView
            android:id="@android:id/list"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    <com.melnykov.fab.FloatingActionButton
            android:id="@+id/fab"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|right"
            android:layout_margin="16dp"
            android:src="@drawable/ic_action_content_new"
            fab:fab_colorNormal="@color/primary"
            fab:fab_colorPressed="@color/primary_pressed"
            fab:fab_colorRipple="@color/ripple" />
</FrameLayout>

3) Attach the FAB to AbsListView, RecyclerView or ScrollView :

ListView listView = (ListView) findViewById(android.R.id.list);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.attachToListView(listView);

Check the sample project to see how to use custom listeners if you need to track scroll events.

4) Add the namespace xmlns:fab="http://schemas.android.com/apk/res-auto" to your layout file.

5) Set an icon for the FloatingActionButton using android:src xml attribute. Use drawables of size 24dp as specified by guidelines. Icons of desired size can be generated with Android Asset Studio.
