Android convert int to dp
Raw
.kt
OBS: O var_number_int é a varável que recebera o valor a ser convertido em DP
(int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, var_number_int, getResources().getDisplayMetrics())
##KOTLIN
val Int.dp: Int
get() = (this * Resources.getSystem().displayMetrics.density + 0.5f).toInt()
val Float.dp: Int
get() = (this * Resources.getSystem().displayMetrics.density + 0.5f).toInt()
Usage then would be cleaner, for example:
// before:
view.setPadding(ctx.dip(8), ctx.dip(16), ctx.dip(8), ctx.dp(16))
// after:
view.setPadding(8.dp, 16.dp, 8.dp, 16.dp)
