Setting the margin for NavigationDrawer elements

My problem is that I cannot set the margin correctly in my navbox. I tried changing the margin of any kind and element, but it doesn't seem to work. All I get is the space between the ActionBar and the NavigationDrawer (and the start of the page). I think the problem is with my ListItem layout, but I'm not sure. This is a photo of what I get

And these are my layouts and code files.

Main layout

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="@+id/drawer_layout">

<android.support.v4.widget.SwipeRefreshLayout

android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="@+id/refreshSites"
tools:context=".MyActivity">

<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/sitesList"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"/>
</android.support.v4.widget.SwipeRefreshLayout>

<RelativeLayout
    android:layout_width="280dp"
    android:layout_height="fill_parent"
    android:id="@+id/drawerPane"
    android:layout_gravity="start">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:layout_marginTop="15dp">

<ListView android:id="@+id/left_drawer"
    android:layout_width="280dp"

    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:choiceMode="singleChoice"
    android:divider="@android:color/white"
    android:dividerHeight="0dp"
    android:layout_marginLeft="15dp"
    android:background="#FFF">
    </ListView>

    </LinearLayout>
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>

      

        
        
        
      

    

drawer_list_item.xml

<?xml version="1.0" encoding="utf-8"?>
    <TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
    android:layout_marginLeft="50dp"
    android:layout_marginTop="15dp"
    android:layout_marginStart="50dp"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:textColor="#222"/>

      

        
        
        
      

    

My code snippet that works with NavigationDrawer

 mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(R.id.left_drawer);   
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
        R.layout.drawer_list_item, mPlanetTitles)); //mPlanetTitles is String array

      

        
        
        
      

    

So the question is, how do you set these fields correctly?
