How get a text size in SP (Scaled Pixel) directly from a TextView?

Question

I`ll wish change the text size in run-time based in the old size.

Something like:

textMove.setTextSize(textMove.getTextSPSize()  + sizeFontScale);

What about:

float px = editext.getTextSize();
float sp = px / getResources().getDisplayMetrics().scaledDensity;

Made my day! I was trying to make two buttons with dynamic but equal text size and this was what I was looking for. – Maurici Guell Hernandez Nov 26 '19 at 11:22

So... setTextSize(int) actually assumes Scaled Pixels. getTextSize() returns the actual pixels. If you want to increase by an amount of actual pixels then you can call getTextSize(), add whatever, then call setTextSize(TypedValue.COMPLEX_UNIT_PX, newValue). I guess I'm kind of wondering if you really want to do everything in Scaled Pixels.
