Location Based Services Part-III (Get Updated Address also with Latitude & Longitude)

" Jai Saraswati Maa"

Please refer Part - II  of LBS

In this example you will also get Address of your new updated location.

In previous example i have added only one Button & one Text View in Layout.

One method which is on onClick of Button.

Changed from previous example are in Bold Italic. 

A. Changed Layout file is activity_main.xml file is as

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

<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:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context="com.exam.ravi.locationbsex1.MainActivity">

    <TextView        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="Ltitude and  Longitude... "

        android:id="@+id/textLocation"

        android:textSize="20dp"/>

    <Button        android:layout_width="wrap_content"

        android:layout_height="wrap_content"        android:text="GetAddress"

        android:onClick="findAddress"

        android:id="@+id/butAdd"

        android:layout_below="@+id/textLocation"

        android:layout_marginTop="10dp"/>

    <TextView        android:layout_width="wrap_content"

        android:layout_height="match_parent"

        android:id="@+id/textAdd"

        android:textSize="15sp"

        android:layout_below="@+id/butAdd"

        android:layout_marginTop="10dp"/>

</RelativeLayout>
