setCompoundDrawables on drawable shape with no effect

I'm trying to set an overline to a TextView using Compound Drawables. I've created a line shape in an XML drawable resource which looks like this:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="line">
            <stroke android:width="1dp" android:color="#000000" />
            <solid android:color="#00000000" />
</shape>

Now I'm trying to put it as an overline to my TextView like this:

TextView root=(TextView)findViewById(R.id.root);
Drawable background=getResources().getDrawable(R.drawable.overline);
root.setCompoundDrawables(null,background,null,null);

But it completely ignores the instruction and the overline doesn't appear. I've also considered using CompoundDrawablesWithIntrinsicBounds, but that doesn't work either. Is the XML for the shape wrong or am I using the method in the wrong way? Thank you very much in advance!

EDIT: I tried with the XML android:drawableTop property, but still no luck. At this point I think that there's clearly a problem with the shape itself. Complete code here:

activity_my.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context=".MyActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/hello"
        android:textSize="30sp"
        android:drawableTop="@drawable/overline"
        android:text="Ciao" />

</RelativeLayout>

overline.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="line">
            <stroke android:width="1dp" android:color="#000000" />
            <solid android:color="#00000000" />
</shape>

My java is the exact same one as the "Hello World" default example given in Android Studio:

package tesi.bordengsberiment;

import android.app.Activity;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Rect;
import android.os.Bundle;
import android.util.AttributeSet;
import android.util.Log;
import android.util.TypedValue;
import android.view.Menu;
import android.view.MenuItem;
import android.view.ViewTreeObserver;
import android.widget.TextView;

public class MyActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.my, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

I had experienced the same problem before. You want to use
root.setCompoundDrawablesWithIntrinsicBounds();
