I'm trying to add a little space between lines to my TextViews using
Extra spacing between lines of text,
as a multiplier.
Must be a floating point value, such
There is a solution:
<resources> <item name="text_line_spacing" format="float" type="dimen">1.0</item> </resources>
In this way, your float number will be under @dimen. Notice that you can use other "format" and/or "type" modifiers, where format stands for:
Format = enclosing data type:
and type stands for:
Type = resource type (referenced with R.XXXXX.name):
To fetch resource from code, you should use this snippet:
TypedValue outValue = new TypedValue(); getResources().getValue(R.dimen.text_line_spacing, outValue, true); float value = outValue.getFloat();
I know that this is confusing (you'd expect call like
getResources().getDimension(R.dimen.text_line_spacing)), but Android
dimensions have special treatment and pure "float" number is not valid dimension.
Additionally, there is small "hack" to put float number into dimension, but be WARNED that this is really hack, and you are risking chance to lose float range and precision.
<resources> <dimen name="text_line_spacing">2.025px</dimen> </resources>
and from code, you can get that float by
float lineSpacing = getResources().getDimension(R.dimen.text_line_spacing);
in this case, value of
2.024993896484375, and not
2.025 as you would expected.
