Features

• Aligned text so you vertically align this in the same layout as a MaterialEditText (as shown below in the last screenshot)
  • Make sure that your MaterialEditText uses a text size of 16sp
    • See https://material.io/guidelines/components/text-fields.html#text-fields-states
• Added alwaysShowFloatingLabel
• Set minSdkVersion to 16 to drop the NineOldAndroids animation library dependency

Here is how it looks like when it is aligned with a MaterialEditText embedded in a dialog:

Gradle Dependency

Use this dependency in your build.gradle file to reference this library in your project

compile 'com.github.ganfra:material-spinner:1.1.2'

If you use other libraries requiring appcompat-v7 like MaterialEditText make sure to exclude them if you have issue at compile time :

compile ('com.github.ganfra:material-spinner:1.1.2'){
        exclude group: 'com.nineoldandroids', module: 'library'
        exclude group: 'com.android.support', module: 'appcompat-v7'
}

Thanks

Many thanks to Matías Dumrauf to help me supporting this library!

Usages

In the xml :

<fr.ganfra.materialspinner.MaterialSpinner
        android:id="@+id/spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" 
        app:ms_multiline="false"
        app:ms_dropDownHintView="@layout/my_custom_dropdown_hint_item_layout"
        app:ms_hintView="@layout/my_custom_hint_item_layout"
        app:ms_hint="hint"
        app:ms_enableFloatingLabel="false"
        app:ms_enableErrorLabel="false"
        app:ms_floatingLabelText="floating label"
        app:ms_baseColor="@color/base"
        app:ms_highlightColor="@color/highlight"
        app:ms_errorColor="@color/error"
        app:ms_typeface="typeface.ttf"
        app:ms_thickness="2dp"
        app:ms_hintColor="@color/hint"
        app:ms_arrowColor="@color/arrow"
        app:ms_arrowSize="16dp"
        app:ms_alignLabels="false"
        app:ms_floatingLabelColor="@color/floating_label"/>

You can set a hint and a floating label text. If no floating label text is provided, the hint will be set instead.

Java side, you use it like a regular spinner, setting an adapter to it.

 String[] ITEMS = {"Item 1", "Item 2", "Item 3", "Item 4", "Item 5", "Item 6"};
 ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, ITEMS);
 adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
 spinner = (MaterialSpinner) findViewById(R.id.spinner);
 spinner.setAdapter(adapter);

If you need to set an error message, you can do it the same way than with an EditText :

 //Activate
 spinner.setError("Error");
 //Desactivate
 spinner.setError(null);

You can choose to have a scrolling animation or to set the error message on multiple lines with the "ms_multiline" attribute in xml (default is true).
