DecimalFormat not formatting my numbers correctly

Question

I want to round all of my numbers to 1 decimal place.

For example

22.0
-6.1

I am using:

DecimalFormat decimalFormat = new DecimalFormat("0.0");
middlePanelTextView.setText(decimalFormat.format(score.getElevationAngle()));

But whole numbers don't have a 0 appended to it.

-18 should be -18.0 etc.

instead my value shows up as -18.

Answer 1

My TextView was cutting off the digits. My fault. Shrank font size.

Answer 2

.@ represents a significant digit 0 doesn't.
.# represents and optional digit So try "##@.@"

I'm not sure about the syntax: but the above article should give you all you need.

Answer 3

Try

middlePanelTextView.setText(""+decimalFormat.format(score.getElevationAngle()));

Answer 4

Try using

DecimalFormat decimalFormat = new DecimalFormat("#.#");

as the constructor parameter instead.

Answer 5

Try using the following code:

DecimalFormat decimalFormat = new DecimalFormat("0.0#");
