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.
.@ 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.
尝试
middlePanelTextView.setText(""+decimalFormat.format(score.getElevationAngle()));
My TextView was cutting off the digits. My fault. Shrank font size.
Try using
DecimalFormat decimalFormat = new DecimalFormat("#.#");
as the constructor parameter instead.
尝试使用以下代码:
DecimalFormat decimalFormat = new DecimalFormat("0.0#");
