Meter Number Picker

The android library that provides a simple and customizable NumberPicker styled as meter. It's based on NumberPicker.

Usage

Make sure you've added maven central to the list of your repositories at the root build.gradle:

repositories {
    mavenCentral()
}

Then add a dependency into your module's build.gradle:

dependencies {
    implementation 'com.alex-zaitsev:meternumberpicker:1.0.2'
}

Content

The library contains 2 views: MeterNumberPicker and MeterView. MeterNumberPicker is a base block for MeterView. On the screenshot above whole view is the MeterView and a single block of it is MeterNumberPicker. They are pretty simple, you can easily create your own meter class based on them.

Usage

Firstly, create a style for your number picker:

<style name="MeterNumberPickerStyle">
    <item name="mnp_min">0</item>
    <item name="mnp_max">9</item>
    <item name="mnp_textColor">@android:color/white</item>
    <item name="mnp_textSize">50sp</item>
    <item name="mnp_paddingHorizontal">5dp</item>
    <item name="mnp_paddingVertical">25dp</item>
</style>

Then, create a style for your meter view and pass the previous style:

<style name="MeterViewStyle">
    <item name="mv_firstColor">@android:color/black</item>
    <item name="mv_numberOfFirst">5</item>
    <item name="mv_numberOfSecond">1</item>
    <item name="mv_pickerStyle">@style/MeterNumberPickerStyle</item>
    <item name="mv_secondColor">@android:color/holo_red_dark</item>
</style>

Almost there! Now create your view and apply the style:

<com.alexzaitsev.meternumberpicker.MeterView
    android:id="@+id/meterView"
    style="@style/MeterViewStyle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

You can use MeterNumberPicke directly without MeterView wrapper. Look at the MeterView sources to catch more details.
