Combines the TickerView & SparkView libraries to mimic the functionality of the sparkline chart from the Robinhood stock trading application.
Add a RobinhoodChartClone
to your view:
<github.bandrews568.robinhoodchartclone.RobinhoodChartClone
android:id="@+id/robinhood_chart_clone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
<!-- Choices: positive, negative, neutral -->
app:chart_theme="neutral" />
Displaying data is very simple:
- Make a list with your data represented as
DataPoint
objects - call
updateDataPoints(myListOfDataPoints)
with that list
updateDataPoints(dataPoints: List<DataPoint>)
is currently the only way to update the data points
val dataPoints: List<DataPoint> = listOf(DataPoint(34.34, 1527804000L), DataPoint(24.34, 15278044000L))
robinhood_chart_clone.updateDataPoints(dataPoints)
Determine what data to show by implementing the TimePeriodChangeListener
for a callback when a radio button is checked:
class RobinhoodChartCloneSampleActivity : AppCompatActivity(), TimePeriodChangeListener {
override fun onStart() {
super.onStart()
robinhood_chart_clone_sample.timePeriodChangeListener = this
}
override fun timePeriodChange(timePeriod: TimePeriod) {
// Use the TimePeriod to determine the data points to display
}
}
Reset the chart back to its default state:
robinhood_chart_clone.reset()
Add the dependency to your build.gradle.
dependencies {
implementation 'github.bandrews568.robinhoodchartclone:robinhoodchartclone:1.0.0'
}
