An android custom view to show ratings

Add this to your module build.gradle:

dependencies {
    implementation 'dev.kunaal:ratings_view:0.0.8'
}

• RatingsView
  • Dependency
• Table of Contents
• Usage
  • Basic
  • Rating Number
  • Rating Text Color
  • Rating Arc Color
  • Rating Arc Width Scale
  • Background Color
  • Multiple Arc (Threshold) Colors
  • Loading Animation

<dev.kunaal.ratings_view.RatingsView
        app:textColor="@color/colorAccent"
        app:arcColor="@color/colorAccent"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

val ratingsView = findViewById<RatingsView>(R.id.ratings_view)

ratingsView.rating = 84

This will animate the number to 84, as well as the arc itself.

The rating text size can be changed by:

ratingsView.textScale = 1.5F

Or via XML by:

app:textScale="1.5"

This will increase the text size by 50% of it's normal size. By default this value is set to 1F

The text color can be changed by:

ratingsView.setTextColor(Color.GREEN)

Or via XML by:

app:textColor="@color/green"

By default this value is set to R.attr.colorAccent

The arc color can be changed by:

ratingsView.setArcColor(Color.GREEN)

Or via XML by:

app:arcColor="@color/green"

By default this value is set to R.attr.colorPrimary

The arc width can be changed by:

ratingsView.setArcWidthScale(1.5F)

Or via XML by:

app:arcWidthScale="1.5"

This will increase the text size by 50% of it's normal size. By default this value is set to 1F

The background color can be changed by:

ratingsView.setBgColor(Color.ORANGE)

Or via XML by:

app:bgColor="@color/orange"

To remove the background color, set the background color to android.R.color.transparent

By default there is no background color.

Arc color can be changed depending on the ratings value.

ratingsView.addArcThresholdColor(0, Color.RED)
ratingsView.addArcThresholdColor(50, Color.GREEN)

This will change the arc color to red if the rating number is in-between 0-49, and green if the rating number is in-between 50-100

A more convenient way of adding colors is by adding a map.

private val colorsMap = mapOf<Int, Int>(
            0 to Color.RED,
            25 to Color.ORANGE,
            50 to Color.YELLOW,
            75 to Color.GREEN
    )

ratingsView.addArcThresholdColor(colorsMap)

The following colors will apply:

• 0 - 24 => Red
• 25 - 49 => Orange
• 50 - 74 => Yellow
• 75 - 100 => Green

To replace a color, just set it again:

// 0 - 100 is Red
ratingsView.addArcThresholdColor(0, Color.RED)
// 0 - 100 is Green now
ratingsView.addArcThresholdColor(0, Color.GREEN)

To replace multiple colors, use a map.

All colors can be removed by calling:

ratingsView.removeAllArcThresholdColor()

This will set the arc color to the default color, which is the color defined by app:arcColor in the XML, or the primary color (R.attr.colorPrimary) of the app.

A loading animation can be started by ratingsView.startLoadingAnimation() and stopped by ratingsView.stopLoadingAnimation()

More conveniently, as the view is self-aware of it's loading state, ratingsView.toggleLoadingAnimation() can be called to automatically toggle between start and stop loading states

While in loading state, the outer arc uses the arcColor and the inner arc uses the textColor.
