Android-gettextsize The return value is in pixels (px), settextsize () in SP

When you use the following code, you find that the font size does not grow larger, but it becomes smaller:
size = (int) mtext.gettextsize () + 1;
Mtext.settextsize (size);
It was later found that the GetTextSize return value is in pixels (px), and Settextsize () is in SP, which results from inconsistent units.


Here you can use a different form of settextsize () to specify the unit:
settextsize (int unit, int size)
TypedValue.COMPLEX_UNIT_PX:Pixels
TypedValue.COMPLEX_UNIT_SP:Scaled Pixels
TypedValue.COMPLEX_UNIT_DIP:Device Independent Pixels


The following is normal:
size = (int) mtext.gettextsize () + 1;
Mtext.settextsize (typedvalue.complex_unit_px, size);
