it is not possible, though You better do it by taking width and height of screen like below in your java code, and
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
then calculate your margin from screen size, and set it by
setmargin(int x) //method of view/layout.
this way you can set margin depending on the screen size not fixed for all screen, and basically it is like setting in percentage but from Java code.

Using getWidth() and getHeight() is deprecated in API level 13+. developer.android.com/reference/android/view/Display.html. Use getSize(point) instead.

@maraci check my another answer for your concern Link >> stackoverflow.com/a/11483404/519718
It became possible with Guidelines introduced in ConstraintLayout.
Here's the example of TextView placed at 60% of screen width and 25% of screen height:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
app:layout_constraintLeft_toLeftOf="@+id/guideline1"
app:layout_constraintTop_toTopOf="@+id/guideline2" />
<android.support.constraint.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/guideline1"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.6" />
<android.support.constraint.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/guideline2"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.25" />
</android.support.constraint.ConstraintLayout>

If you are trying to share sreen width between your controls in percentage. Best way to do that in android is using weight property for them. Check following URL for more details.

Though it is quite late, it can be done with Android percentageRelativeLayout https://developer.android.com/reference/android/support/percent/PercentRelativeLayout.html One can use percentage with some attributes but not all are supported. Like padding is still not supported in percentage whereas margin is.
