Can't Center Navigation Drawer Items Vertically

Main activity layout (removed the irrelevant elements): Copy

then try, it is working for me.

Solution 2:

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

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#eeeeee" >
    </FrameLayout>

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#333333"
        android:choiceMode="singleChoice"
        android:divider="@android:color/darker_gray"
        android:dividerHeight="1dp" />
</android.support.v4.widget.DrawerLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="50dp"
   android:orientation="horizontal" >
<TextView
    android:id="@+id/text"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center|left"
    android:padding="5dp"
    android:text="Medium Text"
    android:textColor="#FB9200" />
</LinearLayout>

Solution 3:

drawer_item.xml:

<RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:text="a" />
    </RelativeLayout>

Solution 4:

Probably you should change the gravity of items to:

android:gravity="center|center_vertical"
