android-下拉框Spinner

https://github.com/arcadefire/nice-spinner

Usage

dependencies {
    compile 'com.github.arcadefire:nice-spinner:1.3.1'
}

The usage is pretty straightforward. Add the tag into the XML layout:

 <org.angmarch.views.NiceSpinner
   android:id="@+id/nice_spinner"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_margin="16dp"/>

• Note: change layout_width to at least the width of the largest item on the list to prevent resizing

Then use this snippet to populate with contents:

 NiceSpinner niceSpinner = (NiceSpinner) findViewById(R.id.nice_spinner);
 List<String> dataset = new LinkedList<>(Arrays.asList("One", "Two", "Three", "Four", "Five"));
 niceSpinner.attachDataSource(dataset);
