Android - text size on particular resolution - setting programatically

I am programming application, which will be used on various kinds of resolutions, but let's say, we would keep to the density. For medium, high and low I am setting it's own drawables, but it still doesn's solve my problem, so I am wondering, how to set values dependently on actual pixel screen 开发者_JS百科density in Java code?

In this time I have to in XML set smaller letters and smaller textviews to fit it into low resolution screen, on the other hand, high density screen is used from about 60% and text fields are too small. I am wondering if there is some way how to, during the start of the program, in some If loop find out, what the resolution is and then set layout_height and textSize for items I want.

Thanks

well before moving ahead to set the text size programatically, I recommend you to set the Textsize property's value in dip instead of px. it seems that you have marked the textsize value in px.
