This is an easy to use custom preference, which opens a dialog with a number picker. The value gets automatically saved and you can set the default-, min- and maxValue conveniently in the XML.

<com.vanniktech.vntnumberpickerpreference.VNTNumberPickerPreference
    xmlns:vntnumberpickerpreference="http://schemas.android.com/apk/res-auto"
    android:defaultValue="@integer/font_size_default_value"
    android:key="preference_font_size"
    android:title="@string/font_size"
    vntnumberpickerpreference:vnt_maxValue="@integer/font_size_max_value"
    vntnumberpickerpreference:vnt_minValue="@integer/font_size_min_value"
    vntnumberpickerpreference:vnt_setWrapSelectorWheel="true"/>

or scan the code on your mobile

    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
}

dependencies {
    compile 'com.vanniktech:vntnumberpickerpreference:0.2.0-SNAPSHOT'
}

Go to your preference XML file and insert the above mentioned XML tag. Afterwards you are good to go and can run your project!

final SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
final int fonftSize = sharedPreferences.getInt("preference_font_size", this.getResources().getInteger(R.integer.font_size_default_value));

No configuration needed.
