Implementing the location aware apps on Android

Android provide the platform to build the location aware applications. You can implement the location based application using the android.location package classes. The core of the android location framework is Location Manager. You can request the location manager service from system using the getSystemService API call. See below the implementation for the activity requesting the location of the user from GPS location provider. //create the object for the location manager private LocationManager mLocationManager; //create the object for the GPS location private Location gpsLocation; //frequency for location determination private static final int TEN_SECONDS = 10000; //distance for location determination private static final int TEN_METERS = 10; // Get a reference to the LocationManager object. mLocationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Now implement a check for the location services are enabled on the device or not. protected void onStart() { super.onStart(); // Check if the GPS setting is currently enabled on the device. // This check should be implement in onStart Method as the system calls this method every time the activity resume LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); final boolean gpsProvider = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); if (!gpsProvider) { // Create an alert dialog to request user to enable the location services new EnableGpsDialogFragment().show(getSupportFragmentManager(), "enableGpsDialog"); } } Now add the following method to call the settings interface using the intents (Start another activity) // Method to launch Settings interface private void enableLocationSettings() { Intent settingsIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivity(settingsIntent); } Now implement the dialog interface for user to choose the option to enable the location services /** * Dialog to prompt users to enable GPS on the device. */ private class EnableGpsDialogFragment extends DialogFragment { @Override public Dialog onCreateDialog(Bundle savedInstanceState) { return new AlertDialog.Builder(getActivity()) .setTitle(R.string.enable_gps) .setMessage(R.string.enable_gps_dialog) .setPositiveButton(R.string.enable_gps, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { enableLocationSettings(); } }) .create(); } } Now request the location provider from location manager requestUpdatesFromProvider( LocationManager.GPS_PROVIDER, R.string.not_support_gps); Call this method upon the activity resume by the user. @Override protected void onResume() { super.onResume(); gpsLocation = requestUpdatesFromProvider(); } Now implement the above method to register the provider private Location requestUpdatesFromProvider(final String provider, final int errorResId) { Location location = null; if (mLocationManager.isProviderEnabled(provider)) { mLocationManager.requestLocationUpdates(provider, TEN_SECONDS, TEN_METERS, listener); location = mLocationManager.getLastKnownLocation(provider); } else { Toast.makeText(this, errorResId, Toast.LENGTH_LONG).show(); } return location; } Now create the location listener with the handler methods private final LocationListener listener = new LocationListener() { @Override public void onLocationChanged(Location location) { // A new location update is received. Do something useful with it. Update the UI with // here you will get the location update which you can update in UI } @Override public void onProviderDisabled(String provider) { } @Override public void onProviderEnabled(String provider) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } }; Make sure that you will remove the location updates from activity on onStop method // Stop receiving location updates whenever the Activity becomes invisible. @Override protected void onStop() { super.onStop(); mLocationManager.removeUpdates(listener); } Create your first app to get your location and enjoy with Android.

Using Fragments in Android

You can use the fragments to display the multiple user-interface panes in single screen. The fragments can be create by creating a subclass of the Fragment class. You can use the standard class also to create your own fragments. The standard fragment classes are as follows DialogFragment - displays the floating dialog windowListFragment - display the list of items managed by the adapterPreferencesFragment - displays a hierarchy of objects (settings)The fragment class provide the similar methods like activity to implement its lifecycle. The methods which you must implement while designing the fragment are as follows OnCreate() - The system calls this when the system is creating the fragment. OnCreateView() - The system calls this when first time the fragment is drawing its user interface. OnPause() - The system calls this when user is leaving the fragment and the fragment is moving to back-stack. For Example the SampleFragment extending the Fragment class. The onCreateView method provides the UI for the fragment. getFragmentManager() FragmentTransaction fragmentTransaction = fragmentManager.

Use Dialog Fragments in Honeycomb

Using Dialog Fragments in Honeycomb

Honeycomb (Android 3.x) introduced the Fragments to better utilize the UI areas and logic across the multiple activities of the in an application. The showDialog/dismissDialog methods in Activity are being deprecated to promote the DialogFragments This post shows a simple DialogFragment example. The example layout file for the dialog is as follows               Create the Dialog Class The dialog class extends the DialogFragment (to support the DialogFragment on other devices I included the DialogFragment from version 4)import android.support.v4.app.DialogFragment; // ... public class SampleDialog extends DialogFragment {     private EditText mEditText;     public SampleDialog() {         // Empty constructor required for DialogFragment     }     @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container,             Bundle savedInstanceState) {         View view = inflater.inflate(R.layout.fragment_edit_name, container);         mEditText = (EditText) view.findViewById(R.id.txt_your_name);         getDialog().setTitle("Hello!CreativeAndroidApps");         return view;     } }Showing the Dialog Box in a Fragment Activityimport android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentManager; // ... public class FragmentDialogDemo extends FragmentActivity implements SampleDialogListener {     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);         showSampleDialog();     }     private void showSampleDialog() {         FragmentManager fm = getSupportFragmentManager();         SampleDialog sampleDialog = new SampleDialog();         sampleDialog.show(fm, "fragment_edit_name");     }     @Override     public void onFinishEditDialog(String inputText) {         Toast.makeText(this, "Hi, " + inputText, Toast.LENGTH_SHORT).show();     } } Please provide your most valuable comments to improve this post.

Parcerable つよい Array100 てがる AlertDialog DialogFragmentどうするの？

Im Banne des blonden Satans (OT: La Môme vert-de-gris) | Frankreich 1953 | Regie: Bernard Borderie

Die Frauen schmachten Lemmy Caution an. Unten: Eddie Constantine und Jacqueline Noëlle.

Dialogfragment:

Lemmy Caution (flirtet mit der Barfrau im Flughafen): „Meine Mutter hat gesagt, daß es zwei Sorten Frauen gibt: die einen verderben uns und die anderen nicht. Mir sind die lieber, die uns verderben.“

Barfrau: „Und warum?“

Lemmy Caution (nach unten blickend): „Ja, die haben meist viel hübschere Beine.“

Barfrau: „Und Sie? Sie sind wohl aus dem heißen Süden Amerikas?“

Honeycomb introduced Fragments to support reusing portions of UI and logic across multiple activities in an app. In parallel, the showDialog / dismissDialog methods in Activity are being deprecated in favor of DialogFragments. In this post, I’ll show how to use DialogFragments with the v4 support library (for backward compatibility on pre-Honeycomb devices) to show a simple edit dialog and return a result to the calling Activity using an interface. For design guidelines around Dialogs, see the Android Design site....
