Android Widget

Circular Counter

Circular Counter is an Android Widget I needed to implement for an application I was developing. As it could be useful to more people, I tried to make it generic enough to share and be used by others.

The view shows a value in the center together with 3 bars that grow depending on the values received. Digging into the code you can easily increase or decrease the number of bars.

Usage

Add CircularCounter widget to your layout. Configure the view customization elements using styleable attributes or/and programatically. This is a basic example, explore the code to get to know it in detail.

    <com.db.circularcounter.CircularCounter
        xmlns:counter="http://schemas.android.com/apk/res-auto"
        android:id="@+id/counter"
        android:layout_width="300dp"
        android:layout_height="300dp"
        counter:range="60"
        counter:textSize="100sp"
        counter:textColor="#ffffff"
        counter:metricSize="20sp"
        counter:metricText="metric"
    />

    //First Bar
    counter.setFirstWidth(getResources().getDimension(R.dimen.first))
    counter.setFirstColor(Color.parseColor(colors[0]))

    //Second Bar
    counter.setSecondWidth(getResources().getDimension(R.dimen.second))
    counter.setSecondColor(Color.parseColor(colors[1]))

    //Third Bar
    counter.setThirdWidth(getResources().getDimension(R.dimen.third))
    counter.setThirdColor(Color.parseColor(colors[2]))
            
    counter.setBackgroundColor(Color.parseColor(colors[3]));

To pass values to the view use setValues(value1, value2, value3). First value will be the one shown in text.
