Merhaba arkada\u015flar,<\/p>\n\n\n\n

Bug\u00fcn sizlerle beraber Android telefonunuzdaki GPS servislerini kullanarak konum bilgilerine eri\u015fme konusunu irdeleyece\u011fiz.  \u00d6ncelikle bu konuya ge\u00e7meden \u00f6nce co\u011frafi koordinatlardan bahsetmek isterim.
D\u00fcnyam\u0131z\u0131n kendine has bir \u015fekli vard\u0131r ki bu \u015fekle Geoit denir. D\u00fcnyam\u0131z\u0131n \u00fczerinden ge\u00e7en yatay ve dikey do\u011frular vard\u0131r. Biz bu do\u011frulara s\u0131ras\u0131yla enlem(Latitude) ve boylam(Longitude) deriz. Bu do\u011frulara ait de\u011ferler ise bizim konumumuzu belirler.<\/p>\n\n\n\n

\u00dclkemiz, Kuzey Yar\u0131m K\u00fcre\u2019de, 36-42 derece kuzey enlemleriyle 26-45 derece do\u011fu boylamlar\u0131nda aras\u0131nda yer al\u0131r.<\/p>\n\n\n\n

Gelelim i\u015fin Android k\u0131sm\u0131na. Android i\u015fletim sistemi, y\u00fckl\u00fc oldu\u011fu cihazlara GPS kullan\u0131m\u0131 ve bu bilgilerin kullan\u0131c\u0131 taraf\u0131ndan izin verilmi\u015f uygulamalarla payla\u015f\u0131m\u0131 konusunda imkan sa\u011flar.<\/p>\n\n\n

\"\"<\/a><\/figure>\n<\/div>\n\n\n

1)Gerekli \u0130zinler<\/h3>\n\n\n\n

AndroidManifest.xml<\/strong> dosyan\u0131z\u0131 a\u00e7\u0131n ve a\u015fa\u011f\u0131daki izinleri ekleyin.<\/p>\n\n\n\n

<uses-permission android:name=\"android.permission.ACCESS_FINE_LOCATION\"\/>\n<uses-permission android:name=\"android.permission.ACCESS_COARSE_LOCATION\"\/><\/pre>\n\n\n\n
2)Layout Tasar\u0131m\u0131<\/h3>\n\n\n\n
\u015eimdi ise uygulamam\u0131z\u0131n aray\u00fcz tasar\u0131m\u0131n\u0131 yapaca\u011f\u0131z. Ve bize hayati derecede laz\u0131m olan \u015fey 2 adet textview. \u00c7\u00fcnk\u00fc biz bu textviewlere yazd\u0131raca\u011f\u0131z ald\u0131\u011f\u0131m\u0131z enlem ve boylam de\u011ferlerini. A\u015fa\u011f\u0131daki kodlar kodlar\u0131 layout dosyan\u0131za eklerseniz, bizim i\u00e7in yeterli olur.<\/p>\n\n\n\n
<TextView\n    android:layout_width=\"match_parent\"\n    android:layout_height=\"wrap_content\"\n    android:id=\"@+id\/txtEnlem\"\n    android:textAlignment=\"center\"\n    android:textSize=\"21sp\"\n    android:textColor=\"#ffffff\"\/>\n<TextView\n    android:layout_width=\"match_parent\"\n    android:layout_height=\"wrap_content\"\n    android:id=\"@+id\/txtBoylam\"\n    android:textAlignment=\"center\"\n    android:textSize=\"21sp\"\n    android:textColor=\"#ffffff\"\/><\/pre>\n\n\n\n
3)Kodlama<\/h3>\n\n\n\n
Activity s\u0131n\u0131f\u0131n\u0131z\u0131 a\u00e7\u0131n ve LocationListener<\/strong> s\u0131n\u0131f\u0131n\u0131 implements edin. Hata verecektir ve sizden implemente edilen aray\u00fcze ait methodlar\u0131 eklemenizi isteyecetir. Implement methods diyerek bu hatay\u0131 \u00e7\u00f6zebilirsiniz.
Son durumda \u015fu \u015fekilde.<\/p>\n\n\n\n
public class MainActivity extends Activity implements LocationListener<\/pre>\n\n\n\n
sonras\u0131nda s\u0131n\u0131f\u0131n hemen i\u00e7inde en \u00fcst k\u0131s\u0131mda her yerden eri\u015febilmek i\u00e7in bir global de\u011fi\u015fken tan\u0131ml\u0131yoruz.<\/p>\n\n\n\n
public LocationManager locationManager;\nTextView txtEnlem,txtBoylam;<\/pre>\n\n\n\n
Sonra ise onCreate<\/strong> methodunun i\u00e7ine geliyoruz ve uygulama a\u00e7\u0131l\u0131r a\u00e7\u0131lmaz locationManager<\/strong> nesnemizin bir \u00f6rne\u011fini yarat\u0131yoruz. Ayr\u0131ca enlem ve boylam de\u011ferlerini yazd\u0131raca\u011f\u0131m\u0131z TextViewlerimizin de \u00f6rneklerini yarat\u0131yoruz.<\/p>\n\n\n\n
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);\ntxtEnlem=(TextView)findViewById(R.id.txtEnlem);\ntxtBoylam=(TextView)findViewById(R.id.txtBoylam);<\/pre>\n\n\n\n
Ard\u0131ndan da AndroidManifest<\/strong> dosyas\u0131nda ekledi\u011fimiz izinlerin bir de RunTime s\u0131ras\u0131nda istenmesini sa\u011flamak amac\u0131yla a\u015fa\u011f\u0131daki kodu ekliyoruz.<\/p>\n\n\n\n
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);<\/pre>\n\n\n\n
Bir sonraki ad\u0131mda ise LocationManager<\/strong> nesnemizin g\u00fcncel konumlardan haberdar olabilmesi i\u00e7in a\u015fa\u011f\u0131daki kodu ekliyoruz. 3000 de\u011ferinin girildi\u011fi parametre saniyeyi ifade eder ve 3 saniyede bir g\u00fcncelleme al\u0131nacak anlam\u0131na gelir.<\/p>\n\n\n\n
try\n{\n    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3000, 10, this);\n}\ncatch (SecurityException ex)\n{\n    Toast.makeText(getApplicationContext(),ex.getMessage().toString(),Toast.LENGTH_LONG).show();\n}<\/pre>\n\n\n\n
art\u0131k onCreate<\/strong> methoduyla i\u015fimiz tamamlanm\u0131\u015f oluyor ve b\u00fct\u00fcn ayarlamalar\u0131 da yapm\u0131\u015f oluyoruz. \u015eimdi herhangi bir konum de\u011fi\u015fikli\u011fi oldu\u011funda bir \u015fey olmas\u0131n\u0131 sa\u011flamak i\u00e7in LocationListener<\/strong> aray\u00fcz\u00fcn\u00fc implemente etti\u011fimizde eklenen 4 methoddan 1’i olan onLocationChanged<\/strong> methodunun i\u00e7ini doldurmaya geldi s\u0131ra. A\u015fa\u011f\u0131daki kod ile her konum de\u011fi\u015fikli\u011fi oldu\u011funda yeni konumun enlem ve boylam de\u011ferlerini al\u0131p ekrana yazd\u0131raca\u011f\u0131z.<\/p>\n\n\n\n
txtEnlem.setText(\"Enlem:\"+location.getLatitude());\ntxtBoylam.setText(\"Boylam:\"+location.getLongitude());<\/pre>\n\n\n\n
Evet Arkdada\u015flar bug\u00fcnde Android ve Konum servisleriyle ilgili konumuzu i\u015fledik. Umar\u0131m faydal\u0131 bir yaz\u0131 olmu\u015ftur.<\/p>\n\n\n\n
