SetLayoutParams dip values

Question

I'm trying to use the setLayoutParams method to specify the graphical parameters of my table layout, but I'm not sure if the setLayoutParams method accepts pixel values ​​or dip values, especially in java, the stored values ​​seem to be pixel values, for example, if I declare these two variables:

private int blockDimension = 50; private int blockPadding = 2; 

And then call the method:

 tableRow.setLayoutParams(new LayoutParams( (blockDimension + 2 * blockPadding) * numberOfColumnsInMineField,blockDimension + 2 * blockPadding) ); 

Are they treated like pixels or are they converted after passing to the method? Then if this is not the case, how can I set dip values ​​in java?

Answer 1

Pixel required. To convert dp to pixels, you can use this:

 public int getPx(int dimensionDp) { float density = getResources().getDisplayMetrics().density; return (int) (dimensionDp * density + 0.5f); } 

Answer 2

if you want these values ​​in dip you need to multiply by screen density. You can do this like this:

 float density = getResources().getDisplayMetrics().density
