MaterialNumberPicker

This library intends to give you more flexibility than the Holo NumberPicker that only comes with two themes for customization.

As many Android developers complained about this component since it was released, this library allows you to access some most wanted private attributes through reflection so that you could easily customize your NumberPicker. This lets you get closer from the MaterialDesign guidelines!

Finally, we built on top of it a builder pattern so you can easily create your MaterialNumberPicker from XML or programmatically.

Download

MaterialNumberPicker requires at minimum Android 3.0, same as the native NumberPicker.

Gradle:

compile 'biz.kasual:materialnumberpicker:1.2.1'

Maven:

<dependency>
  <groupId>biz.kasual</groupId>
  <artifactId>materialnumberpicker</artifactId>
  <version>1.2.1</version>
  <type>aar</type>
</dependency>

Eclipse: materialnumberpicker-1.2.1.aar

Usage

You can either define your MaterialNumberPicker via XML or programmatically :

<biz.kasual.materialnumberpicker.MaterialNumberPicker
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:npMinValue="1"
        app:npMaxValue="50"
        app:npDefaultValue="10"
        app:npBackgroundColor="@color/colorAccent"
        app:npSeparatorColor="@color/colorAccent"
        app:npTextColor="@color/colorPrimary"
        app:npTextSize="25sp"/>

MaterialNumberPicker numberPicker = new MaterialNumberPicker.Builder(context)
                .minValue(1)
                .maxValue(10)
                .defaultValue(1)
                .backgroundColor(Color.WHITE)
                .separatorColor(Color.TRANSPARENT)
                .textColor(Color.BLACK)
                .textSize(20)
                .enableFocusability(false)
                .wrapSelectorWheel(true)
                .build();

The latter option only builds the picker for you. It is up to you how you want to display the picker. You can as well insert it in any ViewGroup or inside an AlertDialog as a custom view.

new AlertDialog.Builder(this)
                .setTitle(yourTitle)
                .setView(numberPicker)
                .setPositiveButton(getString(android.R.string.ok), new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Snackbar.make(findViewById(R.id.your_container), "You picked : " + numberPicker.getValue(), Snackbar.LENGTH_LONG).show();
                    }
                })
                .show();
```

By default there is no `NumberPicker.Formatter` when you build your `MaterialNumberPicker` but you can easily attach one to it using the `formatter` builder proprety.
