Programmatically set height on LayoutParams as density-independent pixels

Question

Is there any way to set the height/width of a LayoutParams as density-independent pixels (dp)? It looks like the height/width, when set programmatically, are in pixels and n

Answer 1

 public static int getDPI(int size, DisplayMetrics metrics){
     return (size * metrics.densityDpi) / DisplayMetrics.DENSITY_DEFAULT;        
 }

Call the function like this,

DisplayMetrics metrics;
metrics = new DisplayMetrics();         
getWindowManager().getDefaultDisplay().getMetrics(metrics);

int heigh = getDPI(height or width, metrics);
