Get Lat and Long through either GPS or Network

latitude and longitude android app





You can Find location either GPS_PROVIDER or NETWORK_PROVIDER 


Here is one example which try to find location using GPS , if your GPS not available then     try to use network for find locationGPS or Network not enable then it will ask user to Enable Gps/network Setting.

       double longitude; // longitude

       // The minimum distance to change Updates in meters

and here is Your Favorite MainActivity :)


package com.itdeveloper.khurram;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends Activity {
       // MyLocation class
       MyLocation myLocation;

       @Override
       protected void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              setContentView(R.layout.activity_main);

              Button mylocationBtn = (Button) findViewById(R.id.MyLatLongBtn);
              mylocationBtn.setOnClickListener(new OnClickListener() {

                     @Override
                     public void onClick(View v) {
                           // TODO Auto-generated method stub

                           TextView latitudeTv = (TextView) findViewById(R.id.latitudeTV);
                           TextView longitudeTv = (TextView) findViewById(R.id.longitudeTv);

                           // create class object
                           myLocation = new MyLocation(MainActivity.this);

                           // check if GPS enabled
                           if (myLocation.isLocationAvailable()) {

                                  Double latitude = myLocation.getLatitude();
                                  Double longitude = myLocation.getLongitude();

                                  latitudeTv.setText(latitude.toString());
                                  longitudeTv.setText(longitude.toString());
                           } else {
                                  // can't get location
                                  // GPS or Network is not enabled
                                  // Ask user to enable GPS/network in settings
                                  myLocation.showSettingsAlert();
                           }

                     }
              });

       }
}




and your activity_main.xml



<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/bgimage" >

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="21dp"
        android:text="Longitude"
        android:textColor="@android:color/white"
        android:textSize="18sp" />

    <TextView

        android:text="00"
        android:textColor="@android:color/white"
        android:textSize="18sp" />

    <Button
        android:id="@+id/MyLatLongBtn"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:text="MyLatLong"
        android:textColor="@android:color/white" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_marginTop="50dp"
        android:text="Latitude"
        android:textColor="@android:color/white"
        android:textSize="18sp" />

</RelativeLayout>


then you must have to add Permition in manifest.xml





<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.itdeveloper.khurram"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <uses-permission android:name="android.permission.INTERNET" />


    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.itdeveloper.khurram.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
