Android 在服务中使用地理编码器获取位置地址

Question

我跟随this获取了位置坐标和地址

所以这里它每 10 秒更新一次位置坐标纬度和经度

我正在尝试与他们一起获取位置地址

在这里获取我正在使用的地址 Const class

public class Const {

public static String getCompleteAddressString(Context m_context, double LATITUDE, double LONGITUDE) {
    String strAdd = "";
    Geocoder geocoder = new Geocoder(m_context, Locale.getDefault());
    try {
        List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
        if (addresses != null) {
            Address returnedAddress = addresses.get(0);
            StringBuilder strReturnedAddress = new StringBuilder("");

            for (int i = 0; i < returnedAddress.getMaxAddressLineIndex(); i++) {
                strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
            }
            strAdd = strReturnedAddress.toString();
            Log.v("My Current location add", "" + strAdd.toString());
        }
    } catch (Exception e) {
        e.printStackTrace();
        Toast.makeText(m_context, "Sorry, Your location cannot be retrieved !" + e.getMessage(), Toast.LENGTH_SHORT).show();

    }
    return strAdd;
}
}

现在 Main Activity 要获取我正在使用的地址

private void updateUI() {
mLatitudeTextView.setText(String.format("%s: %f", mLatitudeLabel,
        mCurrentLocation.getLatitude()));
mLongitudeTextView.setText(String.format("%s: %f", mLongitudeLabel,
        mCurrentLocation.getLongitude()));
mLastUpdateTimeTextView.setText(String.format("%s: %s", mLastUpdateTimeLabel,
        mLastUpdateTime));

//For Address

mLocAddTextView.setText(String.format("%s: %s", mLocAddressLabel,
Const.getCompleteAddressString(this, mCurrentLocation.getLatitude(), mCurrentLocation.getLongitude())));
 }

但是这里没有任何显示，任何人都可以告诉我这有什么问题

你的代码很完美

在您的 Const class

中试试这个

strReturnedAddress .append(returnedAddress.getAddressLine(0)).append("\n");

如果您想使用邮政编码、地区和国家...等等...使用

List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
if (addresses != null) {
    Address returnedAddress = addresses.get(0);
    StringBuilder strReturnedAddress = new StringBuilder("");
    for (int i = 0; i < returnedAddress.getMaxAddressLineIndex(); i++) {
                  strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
    }
        strReturnedAddress .append(returnedAddress.getAddressLine(0)).append("\n");
        strReturnedAddress .append(returnedAddress.getLocality()).append("\n");
        strReturnedAddress .append(returnedAddress.getPostalCode()).append("\n");
        strReturnedAddress .append(returnedAddress.getCountryName());
    strAdd  = strReturnedAddress.toString();
    Log.v("My Current location add", "" + streturnedAddressd.toString());
}

要获取 Geocoder 地址，请遵循 Android GeoCode Location
