How to pass value from fragment button to another activity

How to pass value from fragment button to another activity - android

So I have a map fragment for my application for Google maps. I want to pass the value from the marker (lat/lng) to the String holding the location and then I want to pass that value to the TextField in another application. That textfield will then be stored to the SQLite database that I have built.
My current map activity is as follows
public class MapActivity extends FragmentActivity
implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener,
LocationListener,
Serializable {
GoogleMap mMap;
private GoogleApiClient mGoogleApiClient;
private Location mCurrentLocation;
private static final int ERROR_DIALOG_REQUEST = 9001;
private static final int EDITOR_REQUEST_CODE = 1001;
public static final String LOCAT_KEY = "location";
private GoogleApiClient mLocationClient;
private Marker marker;
Bundle bundle;
String value;
private static final double
CITY_LAT = 53.3478,
CITY_LNG = -6.2597;
Circle shape;
public String lat;
public String lng;
public String location;
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
LocationManager service = (LocationManager) getSystemService(LOCATION_SERVICE);
boolean enabled = service
.isProviderEnabled(LocationManager.GPS_PROVIDER);
// check if enabled and if not send user to the GSP settings
if (!enabled) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
// Getting reference to Button
Button btnDraw = (Button) findViewById(R.id.btn_draw);
if (servicesOK()) {
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
if (initMap()) {
gotoLocation(CITY_LAT, CITY_LNG, 12);
mMap.setMyLocationEnabled(true);
mLocationClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
mLocationClient.connect();
} else {
Toast.makeText(this, "Map not connected!", Toast.LENGTH_SHORT).show();
}
} else {
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
}
bundle = new Bundle();
btnDraw.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String location = lat + "," + lng;
// Checks, whether location is captured
((TextView) findViewById(R.id.editLocation)).setText(location);
}
});
}
Note I have only added code down to the actual button that is activated.
My code for the button that is clicked in my XML file is as follows:
<Button
android:id="#+id/btn_draw"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/save_location_btn"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:onClick="mapLocationClick"/>
And finally my code for the editor class is as follows:
public class EditorActivity extends AppCompatActivity {
public static final String KEY_ID = "id";
public static final String KEY_TIME = "time" ;
public static final String KEY_LOCAT = "location";
private String action;
private EditText editor;
private EditText editorDate;
private EditText editorTime;
private EditText editorLocation;
private ImageButton dateButton;
private ImageButton timeButton;
private ImageButton locationButton;
private String noteFilter;
private String oldText;
private String oldDate;
private String oldTime;
private String oldLocation;
String value = null;
#Override

dateButton = (ImageButton) findViewById(R.id.imgButtonCal);
timeButton = (ImageButton) findViewById(R.id.imgButtonClock);
locationButton = (ImageButton) findViewById(R.id.imgButtonMap);
//enableEdit = (FloatingActionButton) findViewById(R.id.fabEdit);
Intent intent = getIntent();
Bundle extras = intent.getExtras();
if (extras == null) {
action = Intent.ACTION_INSERT;

}
else {

if (id == 0){
action = Intent.ACTION_INSERT;
setTitle(getString(R.string.new_note));
long time = intent.getLongExtra(KEY_TIME, 0);
if (time != 0) {
Date d = new Date(time);
String dateString= DateFormat.format("yyyy-MM-dd", `d).toString();`
editorDate.setText(dateString);
}
}
else {
action = Intent.ACTION_EDIT;

Uri uri = Uri.parse(NotesProvider.CONTENT_URI + "/" + id);
noteFilter = DBOpenHelper.NOTE_ID + "=" + uri.getLastPathSegment();
Cursor cursor;
cursor = getContentResolver().query(uri,
DBOpenHelper.ALL_COLUMNS, noteFilter, null, null);
cursor.moveToFirst();
oldText = cursor.getString(cursor.getColumnIndex(NOTE_TEXT));

newFragment.show(getSupportFragmentManager(), "datePicker");
}
public void openMapFragment(View v) {
Intent intent = new Intent(this, MapActivity.class);
startActivity(intent);
}
Anybody help me so when I click on the button it will take the value from the location and save it in the previous class that was loaded up before.

I found the answer. I created the following in my map class
btnDraw.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Checks, whether location is captured
Intent intent = MapActivity.this.getIntent();
intent.putExtra(LATITUDE_EXTRA, lat);
intent.putExtra(LONGITUDE_EXTRA, lng);
MapActivity.this.setResult(RESULT_OK, intent);
MapActivity.this.finish();
}
});
Then I added it to the Editor class by the following.
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MAP_REQUEST_CODE && resultCode == RESULT_OK) {
String lat = data.getStringExtra(MapActivity.LATITUDE_EXTRA);
String lng = data.getStringExtra(MapActivity.LONGITUDE_EXTRA);
editorLocation.setText(lat + ", " + lng);
}
else {
Toast.makeText(this, "Error!", Toast.LENGTH_LONG).show();
}
}
Seems I needed to add a new intent and use the onActivityResult.

LocalBroadcastManager sends data more than once

I have a fragment where when a User inputs a link and hits the button, a service is initiated which processes the link and grabs image or videos if there are any on the url...
But my problem is that the same is downloaded more than once like 2 to 3 times..
here is the fragment -
public class FragmentTwo extends Fragment {

here's the Downloader Service -
public class DownloaderService extends IntentService {
private static final String ACTION_FOO = "com.parrotainment.media.downloader.action.FOO";
private static final String EXTRA_URL = "com.parrotainment.media.downloader.extra.URL";

} else {

}
Intent intent = new Intent(Constants.BROADCAST_ACTION);
intent.putExtra(Constants.MEDIA_INFO, mediaInfo);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
} catch (IOException e) {
e.printStackTrace();
}
}
}
& the Constants -
public final class Constants {
public static final String BROADCAST_ACTION = "com.parrotainment.media.downloader.BROADCAST";
public static final String MEDIA_INFO = "com.parrotainment.media.downloader.MEDIA_INFO";
public static final String MEDIA_NAME = "com.parrotainment.media.downloader.MEDIA_NAME";
public static final String MEDIA_URL = "com.parrotainment.media.downloader.MEDIA_URL";
}

just checking data in your oReceive may help. like this:
if(intent.getAction() != null && intent.getAction().equals("your_constant_item")){
//

Why dialog for enabling dangerous android permissions is shown 2 times?

I am developing an app where I am using android's dialog for granting dangerous permissions. And when I click button for login on LoginActivity I go to Main activity and dialog is show. But when I press BACK button, again this dialog appears! This is my MainActivity(Just to say that my launcher activity is MAinActivity, not LoginActivity):

Google Maps makes the app stop Unfortunately

We are working with an Android Application the first page is Splash screen and the later page is google map .

To ensure that you are using a non-null instance of GoogleMap you should implement OnMapReadyCallback. From the documentation https://developers.google.com/android/reference/com/google/android/gms/maps/OnMapReadyCallback
Once an instance of this interface is set on a MapFragment or MapView object, the onMapReady(GoogleMap) method is triggered when the map is ready to be used and provides a non-null instance of GoogleMap.:
So, your GoogleMapsActivity needs to implement OnMapReadyCallback and you have to move the call your populateMap(); method to the onMapReady method:
public class GoogleMapsActivity extends FragmentActivity implements OnMapReadyCallback {
// ...
#Override
protected void onCreate(Bundle savedInstanceState) {
// Remove populateMap(); and change it for
((MapFragment) getFragmentManager()
.findFragmentById(R.id.map)).getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
populateMap();
}
}

Rerouting in Here Map Android SDK

from my understanding when your position strays off the calculated route, it should trigger a route (re)calculation. I have tried it and I received both onRerouteBegin and onReRouteEnd callbacks. From my observation staying on route does not trigger any re-routing.

Android contact picker returning nulll (resultCode == 0)

I'm new to Android and I'm trying to attach a contact picker to a form. This "contact picker code" works well when I test it with other forms but with this form, the resultCode = RESULT_CANCELED. I have checked other examples, but it doesn't work with this from but still works with other forms.

Finally found a solution, the problem was with the android:launchMode in the manifest.
