Android GPS获取当前经纬度坐标

APP中可能会遇到一种需求,就是将当前所在位置的坐标传到server上,今天我提供三种途径去获取经纬度坐标信息,第一种是通过Android API来实现,另外一种通过百度地图API来实现,第三种通过天地图API来实现。

第一种方法(Android API实现),废话不多说,上代码。

MainActivity代码例如以下:

public class MainActivity extends Activity {
	private static final String TAG = MainActivity.class.getSimpleName();
	private double latitude = 0.0;
	private double longitude = 0.0;
	private TextView info;
	private LocationManager locationManager;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		info = (TextView) findViewById(R.id.tv);
		locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
		if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
			getLocation();
			//gps已打开
		} else {
			toggleGPS();
			new Handler() {
			}.postDelayed(new Runnable() {
				@Override
				public void run() {
					getLocation();
				}
			}, 2000);

		}
	}

	private void toggleGPS() {
		Intent gpsIntent = new Intent();
		gpsIntent.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
		gpsIntent.addCategory("android.intent.category.ALTERNATIVE");
		gpsIntent.setData(Uri.parse("custom:3"));
		try {
			PendingIntent.getBroadcast(this, 0, gpsIntent, 0).send();
		} catch (CanceledException e) {
			e.printStackTrace();
			locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 0, locationListener);
			Location location1 = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
			if (location1 != null) {
				latitude = location1.getLatitude(); // 经度
				longitude = location1.getLongitude(); // 纬度
			}
		}
	}

	private void getLocation() {
		Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
		if (location != null) {
			latitude = location.getLatitude();
			longitude = location.getLongitude();
		} else {

			locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, locationListener);
		}
		info.setText("纬度:" + latitude + "\n" + "经度:" + longitude);
	}

	LocationListener locationListener = new LocationListener() {
		// Provider的状态在可用、临时不可用和无服务三个状态直接切换时触发此函数
		@Override
		public void onStatusChanged(String provider, int status, Bundle extras) {
		}

		// Provider被enable时触发此函数,比方GPS被打开
		@Override
		public void onProviderEnabled(String provider) {
			Log.e(TAG, provider);
		}

		// Provider被disable时触发此函数,比方GPS被关闭
		@Override
		public void onProviderDisabled(String provider) {
			Log.e(TAG, provider);
		}

		// 当坐标改变时触发此函数,假设Provider传进同样的坐标,它就不会被触发
		@Override
		public void onLocationChanged(Location location) {
			if (location != null) {
				Log.e("Map", "Location changed : Lat: " + location.getLatitude() + " Lng: " + location.getLongitude());
				latitude = location.getLatitude(); // 经度
				longitude = location.getLongitude(); // 纬度
			}
		}
	};

	/*
	 * 
	 * 打开和关闭gps另外一种方法
	 * private void openGPSSettings() {
		//获取GPS如今的状态(打开或是关闭状态)
		boolean gpsEnabled = Settings.Secure.isLocationProviderEnabled(getContentResolver(), LocationManager.GPS_PROVIDER);
		if (gpsEnabled) {
			//关闭GPS
			Settings.Secure.setLocationProviderEnabled(getContentResolver(), LocationManager.GPS_PROVIDER, false);
		} else {
			//打开GPS  
			Settings.Secure.setLocationProviderEnabled(getContentResolver(), LocationManager.GPS_PROVIDER, true);
		}
	}*/
}
main.xml布局例如以下

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="经纬度信息:"
        android:textColor="#660000"
        android:textSize="20sp" />

</LinearLayout>
清单文件例如以下:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.tqmapdemo"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />
  
    <!-- 连接互联网Internet权限 -->
    <uses-permission android:name="android.permission.INTERNET" />
    <!-- GPS定位权限 -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Black" >
        <activity
            android:name="com.example.tqmapdemo.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>
执行结果例如以下
