final CounterView counterView = new CounterView(context);
counterView.setFormatter(new Formatter() {
@Override
public String format(String prefix, String suffix, float value) {
return prefix
+ NumberFormat.getNumberInstance(Locale.US).format(value)
+ suffix;
}
});
counterView.setAutoStart(false);
counterView.setStartValue(200f);
counterView.setEndValue(1000f);
counterView.setIncrement(5f); // the amount the number increments at each time interval
counterView.setTimeInterval(2); // the time interval (ms) at which the text changes
counterView.setPrefix("You have ");
counterView.setSuffix(" points!");
counterView.start(); // you can start anytime if autostart is set to falseFormatter
You can control the text formatting by providing a Formatter. Simply implement the interface com.github.premnirmal.textcounter.Formatter or use one of the formatters under the com.github.premnirmal.textcounter.formatters package.
