" 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>
