I have seen different FloatLabel libraries. But, they all look kind of not following material design rule for looks. Monitoring the Accents, colorControlNormal and all and kinda hard to fix. So I decided to do mine for EditText, Spinner and AutoCompleteTextView and buzz me if you need for any other android.view.widget. After reading someone EditText library I decided to do mine too

set the attrs.xml

Create the layouts using the "Merge" Tag

Then create the class for the view Extending Linear Layout

## Test.java
//Adapter for spinner and autocompletetextview
final String[] COUNTRIES = new String[] {
                "Belgium", "France", "Italy", "Germany", "Spain"
        };

        ArrayAdapter<String> adapters = new ArrayAdapter<String>(this,
                android.R.layout.simple_dropdown_item_1line, COUNTRIES);

//To test Spinner
//XML For Spinner
//======================================
/*<com.testapp.FloatLabelSpinnerView
*        android:id="@+id/mSpinns"
*        android:layout_width="match_parent"
*        android:layout_height="80dp"
*        app:editText_color="@color/colorPrimary"
*        app:editText_size="5sp"//Hint Text Size
*        app:editText_hint="Identity">
*/
mSpinns = (FloatLabelSpinnerView) findViewById(R.id.mSpinns);
        mSpinns.setAdatper(adapters);

//=====================================================
//To set autoCompleteTextView
/*<deliveryscience.testapp.FloatLabelAutoCompleteTextView
        android:id="@+id/floatText"
        android:layout_width="match_parent"
        android:layout_height="80dp"
        android:textSize="17sp"
        android:hint="Password"
        app:editText_color="@color/colorPrimary"
        app:editText_size="5sp"
        app:editText_hint="Password"/>
*/
FloatLabelAutoCompleteTextView floatingLabelAutoCompleteTextView = (FloatLabelAutoCompleteTextView) findViewById(R.id.floatText);
        floatingLabelAutoCompleteTextView.setAdapter(adapters);

//Implementing EditText
/*<deliveryscience.testapp.FloatLabelTextView

        android:layout_height="80dp"
