I have this field:

HashMap<String, HashMap> selects = new HashMap<String, HashMap>();

For each Hash<String, HashMap> I need to create a ComboBox, whose items are the value (which happens to be a HashMap itself) of HashMap <String, **HashMap**>.

By way of (non-functioning) demonstration:

for (int i=0; i < selects.size(); i++) {

    HashMap h = selects[i].getValue();

    ComboBox cb = new ComboBox();

    for (int y=0; y < h.size(); i++) {

        cb.items.add(h[y].getValue);

    }

}

 Here's what described in the documentation, by default it uses the color set in styles.xml attribute colorAccent.

The background color of this aspect defaults to your theme's colorAccent. If you want to modify this at runtime then you can do so via setBackgroundTintList(ColorStateList).

If you want to modify the color:

in XML with attribute app:backgroundTint

<android.support.design.widget.FloatingActionButton

    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:src="@drawable/ic_add"

    app:backgroundTint="@color/orange"

    app:borderWidth="0dp"

    app:elevation="6dp"

    app:fabSize="normal" >

if you want to modify the icon color, you can try

android:tint="@color/colorname"
