Scale textsizes for different screen sizes

Question

I have some layouts and I want to adjust my textsize to the screen size. I used sp for all my sizes, but when I switch to my tablet my text still looks to small.

Is there a common scale formula or something to simply do this ?

Answer 1

try View.getHeight() and View.getWidth() and apply your logic accordingly.

OR

Use this :

Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); 
int width = display.getWidth(); 
int height = display.getHeight();

OR

To get screen size in inches, try :

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
double x = Math.pow(dm.widthPixels/dm.xdpi,2);
double y = Math.pow(dm.heightPixels/dm.ydpi,2);
double screenInches = Math.sqrt(x+y);
Log.d("debug","Screen inches : " + screenInches);

Answer 2

使用dip而不是sp但我确定默认的textsize取决于其容器，例如textView或Button

Answer 3

you can use

android:textSize="dip"

for eg. 10 dip,20 dip
