我正在开发一个名为Location Alarm的基于android的应用程序，如果它进入特定位置，将触发警报并显示通知。但现在我想让它在通知中显示用户输入的注释。任何人都可以帮助我。？
以下是MainActivity的代码
public void onMapClick(LatLng point) {
locationCount++;
// Drawing marker on the map
drawMarker(point);
drawCircle(point);
// Creating an instance of ContentValues
ContentValues contentValues = new ContentValues();
// Setting latitude in ContentValues
contentValues.put(LocationsDB.FIELD_LAT, point.latitude );
// Setting longitude in ContentValues
contentValues.put(LocationsDB.FIELD_LNG, point.longitude);
// Setting zoom in ContentValues
contentValues.put(LocationsDB.FIELD_ZOOM, googlemap.getCameraPosition().zoom);
// Creating an instance of LocationInsertTask
LocationInsertTask insertTask = new LocationInsertTask();
// Storing the latitude, longitude and zoom level to SQLite database
insertTask.execute(contentValues);
Toast.makeText(getBaseContext(), "Marker is added to the Map", Toast.LENGTH_SHORT).show();
// This intent will call the activity ProximityActivity
Intent contentValues1 = new Intent("com.example.locationdetectormechanism.activity.alert");
// Passing latitude to the PendingActivity
contentValues1.putExtra("lat",point.latitude);
// Passing longitude to the PendingActivity
contentValues1.putExtra("lng", point.longitude);
contentValues1.putExtra("note",R.id.et1);
// Creating a pending intent which will be invoked by LocationManager when the specified region is
// entered or exited
pendingIntent = PendingIntent.getActivity(getBaseContext(), 0, contentValues1,Intent.FLAG_ACTIVITY_NEW_TASK);
// Setting proximity alert
// The pending intent will be invoked when the device enters or exits the region 20 meters
// away from the marked point
// The -1 indicates that, the monitor will not be expired
locationManager.addProximityAlert(point.latitude, point.longitude, 20, -1, pendingIntent);
/** Opening the editor object to write data to sharedPreferences */
SharedPreferences.Editor editor = sharedPreferences.edit();
// Storing the latitude for the i-th location
editor.putString("lat"+ Integer.toString((locationCount-1)), Double.toString(point.latitude));
// Storing the longitude for the i-th location
editor.putString("lng"+ Integer.toString((locationCount-1)), Double.toString(point.longitude));
// Storing the count of locations or marker count
editor.putInt("locationCount", locationCount);
/** Storing the zoom level to the shared preferences */
editor.putString("zoom", Float.toString(googlemap.getCameraPosition().zoom));
/** Saving the values stored in the shared preferences */
editor.commit();
//Toast.makeText(getBaseContext(), "Proximity Alert is added", Toast.LENGTH_SHORT).show();
}
以下是我的AlertActivity
public class AlertActivity extends Activity {
String notificationTitle;
String notificationContent;
String tickerMessage;
String tickerMessage1;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
boolean proximity_entering = getIntent().getBooleanExtra(LocationManager.KEY_PROXIMITY_ENTERING, true);
double lat = getIntent().getDoubleExtra("lat", 0);
double lng = getIntent().getDoubleExtra("lng", 0);
String note = getIntent().getStringExtra("note");
String strLocation = Double.toString(lat)+","+Double.toString(lng);
if(proximity_entering){
Toast.makeText(getBaseContext(),"Entering the region" ,Toast.LENGTH_LONG).show();
notificationTitle = "Proximity - Entry";
notificationContent = "Entered the region: " + strLocation;
tickerMessage = "Entered the region: " + strLocation;
tickerMessage1 = "Note :" + R.id.et1;
}else{
Toast.makeText(getBaseContext(),"Exiting the region" ,Toast.LENGTH_LONG).show();
notificationTitle = "Proximity - Exit";
notificationContent = "Exited the region: " + strLocation;
tickerMessage = "Exited the region :" + strLocation;
}
Intent notificationIntent = new Intent(getApplicationContext(),NotificationView.class);
/** Adding content to the notificationIntent, which will be displayed on
* viewing the notification
*/
notificationIntent.putExtra("content", notificationContent );
/** This is needed to make this intent different from its previous intents */
notificationIntent.setData(Uri.parse("tel:/"+ (int)System.currentTimeMillis()));
/** Creating different tasks for each notification. See the flag Intent.FLAG_ACTIVITY_NEW_TASK */
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK);
/** Getting the System service NotificationManager */
NotificationManager nManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
/** Configuring notification builder to create a notification */
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(getApplicationContext())
.setWhen(System.currentTimeMillis())
.setContentText(notificationContent)
.setContentTitle(notificationTitle)
.setSmallIcon(R.drawable.ic_launcher)
.setAutoCancel(true)
.setTicker(tickerMessage)
.setContentIntent(pendingIntent)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 });
/** Creating a notification from the notification builder */
Notification notification = notificationBuilder.build();
/** Sending the notification to system.
* The first argument ensures that each notification is having a unique id
* If two notifications share same notification id, then the last notification replaces the first notification
* */
nManager.notify((int)System.currentTimeMillis(), notification);
/** Finishes the execution of this activity */
finish();
