Enhancement: Allow formatted string in NumericWheelAdapter #3

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Current NumericWheelAdapter implementation only takes an integer, then convert 
to string.  It would be nice if it could allow formatted string i.e. 
00,01,02,... as in minutes or even decimal.

It can be easily done by introducing an additional constructor to 
NumericWheelAdapter:

private String format = null;

public NumericWheelAdapter(int minValue, int maxValue, String format) {
    this.minValue = minValue;
    this.maxValue = maxValue;
    this.format = format;
}

// And modification to the getItem method:

public String getItem(int index) {
    if (index >= 0 && index < getItemsCount()) {
        if(this.format != null) {
            return String.format(this.format, minValue+index);
        } else {
            return Integer.toString(minValue + index);
        }
    }
    return null;
}

I'm attaching a new NumericWheelAdapter.java
