Programmatically set height on LayoutParams as density-independent pixels

You need to convert your dip value into pixels:

int height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, <HEIGHT>, getResources().getDisplayMetrics());

For me this does the trick.

 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);
