   <?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="match_parent"
        android:orientation="vertical" >

        <TextView

First you need to create main.xml in layout folder in res directory. This is the main layout which is loading in your Activity , take two TextView inside main.xml with id named as lat and longi. main.xml is given below.

<?xml version="1.0" encoding="utf-8"?>

<TextView
    android:id="@+id/lat"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="195dp"
    android:text="Lattitude" />

<TextView
    android:id="@+id/longi"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/textView2"
    android:layout_alignParentTop="true"
    android:layout_marginTop="82dp"
    android:text="Longitude" />
