Android设置GPS及获取经纬度坐标

设置部分：

/** * 设置GPS开启或关闭，入口参数为true时开启GPS，为false时关闭GPS * */public void setGPS(boolean on_off) {    boolean gpsEnabled = android.provider.Settings.Secure.isLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER);    Intent gpsIntent = new Intent();        gpsIntent.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");        gpsIntent.addCategory("android.intent.category.ALTERNATIVE");            if(on_off == true)        {    if(!gpsEnabled) {                gpsIntent.setData(Uri.parse("custom:3"));            try {                    PendingIntent.getBroadcast(this, 0, gpsIntent, 0).send();            } catch (CanceledException e) {                    e.printStackTrace();            }    }        }        else {        if(gpsEnabled) {                gpsIntent.setData(Uri.parse("custom:3"));            try {                    PendingIntent.getBroadcast(this, 0, gpsIntent, 0).send();            } catch (CanceledException e) {                    e.printStackTrace();            }    }        }    }

以上代码需要添加如下权限：

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

获取部分：

/** * 获得经纬度函数 * */public void getLongitudeAndLatitude() {setGPS(true);LocationManager loctionManager;String contextService=Context.LOCATION_SERVICE;//通过系统服务，取得LocationManager对象loctionManager=(LocationManager) getSystemService(contextService);String provider=LocationManager.GPS_PROVIDER;Location location = loctionManager.getLastKnownLocation(provider);if(location != null) {longitude = location.getLongitude(); latitude = location.getLatitude();Toast.makeText(getApplicationContext(), String.valueOf(longitude)+ "," + String.valueOf(latitude),Toast.LENGTH_LONG).show();}}

以上代码需要添加如下权限：

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