android numberpicker for floating point numbers
android, numberpicker, spinner
Solution
`NumberPicker` is not just for integers.. Even you can use `Floats` `String` etc.
see this and read about it.

And I had used `NumberPicker` long ago like this and it might be some use posting here:
NumberPicker np;
String nums[]= {"Select Fraction","1/64","1/32","3/64","1/16","5/64","3/32","7/64","1/8","9/64","5/32","11/64","3/16","13/64","7/32","15/64","1/4","17/64","9/32","19/64","5/16","21/64","11/32","23/64","3/8","25/64","13/32","27/64","7/16","29/64"};
np = (NumberPicker) findViewById(R.id.np);
np.setMaxValue(nums.length-1);
np.setMinValue(0);
np.setWrapSelectorWheel(false);
np.setDisplayedValues(nums);
np.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS);
You can make `ArrayList` of any datatype and assign it.
Problem
The user of our app should be able to adjust a floating point number. At the moment, I filled an ArrayAdapter with all possible values and attached it to a spinner. This solution doesn't really meet our expectations, since the spinner dropdown box is way too tall. Is there a better way? I was looking at Numberpicker - but this seems to work only with Integer values. Any ideas? Thanks!
