誰能告訴我如何使用android studio將地址解析器地址存儲在android數據庫中？

Question

我可以看到從GeoCoder代碼獲取的地址（用於單擊偵聽器），並且可以在日志文件中顯示，但無法將該地址存儲在本地DataBase 。

誰能幫我解決這個問題。

提前致謝。

package com.example.raghotham.androidgeocodelocation;


import java.util.List;

public class MainActivity extends Activity {

Button btnGPSShowLocation;
Button btnShowAddress;
TextView tvAddress;
final DatabaseHandler1 db = new DatabaseHandler1(this);

AppLocationService appLocationService;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);




    tvAddress = (TextView) findViewById(R.id.tvAddress);
    appLocationService = new AppLocationService(
            MainActivity.this);

    btnGPSShowLocation = (Button) findViewById(R.id.btnGPSShowLocation);

        @Override
        public void onClick(View arg0) {
            Location gpsLocation = appLocationService
                    .getLocation(LocationManager.GPS_PROVIDER);
            if (gpsLocation != null) {
                double latitude = gpsLocation.getLatitude();
                double longitude = gpsLocation.getLongitude();
                String result = "Latitude: " + gpsLocation.getLatitude() +
                        " Longitude: " + gpsLocation.getLongitude();

                tvAddress.setText(result);

                locationAddress.getAddressFromLocation(latitude, longitude,

            } else {

        String locationAddress;
        switch (message.what) {

                Bundle bundle = message.getData();
                locationAddress = bundle.getString("address");

                Log.d("testing: ", locationAddress);
                break;

        }
        tvAddress.setText(locationAddress);
    }

}

我能夠存儲latitude and longitude但不能存儲地址部分。

只需以String形式返回您的地址，然后使用SQlite將其存儲在本地數據庫中即可。 在SQLite中存儲字符串很容易。 下面是獲取地址的代碼。

 public static String getAddressFromLocation(Context context,
                double latitude, double longitude) {
            String address = "";
            Geocoder geocoder;
            List<Address> listAddresses;

            try {
                geocoder = new Geocoder(context, Locale.getDefault());
                if (isNetworkAvailable(context)) {
                    listAddresses = geocoder
                            .getFromLocation(latitude, longitude, 1);
                    for (Address addrss : listAddresses) {
                        String adminArea = addrss.getAdminArea();
                        Logging(SHOW_LOG, TAG, "adminArea = " + adminArea);

                        String locality = addrss.getLocality();
                        Logging(SHOW_LOG, TAG, "locality = " + locality);

                        String postalCode = addrss.getPostalCode();
                        Logging(SHOW_LOG, TAG, "postalCode = " + postalCode);

                        String address1 = addrss.getAddressLine(0);
                        Logging(SHOW_LOG, TAG, "address1 = " + address1);

                        String cityState = addrss.getAddressLine(1);
                        Logging(SHOW_LOG, TAG, "cityState = " + cityState);

                        String countryName = addrss.getCountryName();
                        Logging(SHOW_LOG, TAG, "countryName = " + countryName);

                    }
                    address = listAddresses.get(0).getAddressLine(0) + " "
                            + listAddresses.get(0).getAddressLine(1) + " "
                            + listAddresses.get(0).getCountryName();
                } else {
                    address = "";
                }
            } catch (Exception e) {
                address = "";
            }

            Log.i(TAG, "address : " + address);
            return address;
        }
