Give padding with setPadding with dip unit not px unit

Question

The method

public void setPadding (int left, int top, int right, int bottom)

someview.setPadding(1,1,1,1);

this will give padding with 1px in each side. How can I give 1dip instead of 1px ?

the values fro left , top right and bottom are in pixels , how can I give values programatically in code in dip ?

Thanks

Answer 1

Use following code to get pixels from given value in dp.

Resources res = getResources();
float value = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, valueInDP, res.getDisplayMetrics());

where valueInDP is value in dp and this will return corresponding pixel value according to screen density.

or you can use following -

float value = valueInDP * getResources().getDisplayMetrics().density;

Answer 2

What is the difference between "px", "dp", "dip" and "sp" on Android?

float scale = context.getResources().getDisplayMetrics().density;
int dpAsPixels = (int) (your_dp_goes_here * scale + 0.5f);

view.setPadding(dpAsPixels , dpAsPixels , dpAsPixels , dpAsPixels );
view.setPaddingRelative(dpAsPixels , dpAsPixels , dpAsPixels , dpAsPixels );
