一般来讲，通过gps获取到经纬度坐标以后，要继续深入的获取该经纬度坐标的城市、街道与精度（误差）等信息。

private String getAddressbyGeoPoint() {
		// 自经纬度取得地址
		StringBuilder sb = new StringBuilder();
		Geocoder gc = new Geocoder(getBaseContext(), Locale.getDefault());
		List<Address> lstAddr = null;
		try {
			lstAddr = gc.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
		} catch (IOException e) {
			Log.e("HangzhouBike", e.getMessage());
		}
		if (lstAddr != null && lstAddr.size() > 0) {
			Address addr = lstAddr.get(0);
			if (addr.getAddressLine(1) != null)
				sb.append(addr.getAddressLine(1)).append(" ");
			if (addr.getAddressLine(2) != null)
				sb.append(addr.getAddressLine(2)).append(" ");
			sb.append(" ±" + location.getAccuracy() + "米");
		}
		return sb.toString();
	}
