Hi I am developing an android app where in I am using an AutoCompleteTextView for searching Names using SimpleCursorAdapter as in below code.
autoCompleteNamadtxt = (AutoCompleteTextView) findViewById(R.id.namadtxt);
dbHelper = new DBHelper(this);
dbHelper.open();
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_dropdown_item_1line,
null,
new String[] { "Namad" },
new int[] {android.R.id.text1});
autoCompleteNamadtxt.setAdapter(adapter);
adapter.setCursorToStringConverter(new SimpleCursorAdapter.CursorToStringConverter() {
#Override
public CharSequence convertToString(Cursor cursor) {
final int colIndex = cursor.getColumnIndexOrThrow("Namad");
return cursor.getString(colIndex);
}
});
adapter.setFilterQueryProvider(new FilterQueryProvider() {
public Cursor runQuery(CharSequence constraint) {
String partial = null;
if (constraint != null)
partial = constraint.toString();
Cursor cursor = dbHelper.getAllNamad(new String[]{partial.trim() + "%"});
startManagingCursor(cursor);
cursor.moveToFirst();
return cursor;
}
});
dbHelper.close();
dbHelper :
public Cursor getAllNamad(String[] param, SQLiteDatabase sqLite) {
Cursor cursor = sqLite.rawQuery("select Id as _id,Namad from Namad Where Namad LIKE ؟", param);
return cursor;
}
when I start to type in AutoCompleteTextView , I face with the following ecxeption, I wonder if someone can help me out.
07-23 09:00:56.209 2398-2419/? W/Filter﹕ An exception occured during performFiltering()!

found the way myself, I have to put "dbHelper.open()" at the begining of "setFilterQueryProvider" function
adapter.setFilterQueryProvider(new FilterQueryProvider() {
public Cursor runQuery(CharSequence constraint) {
dbHelper.open();
Cursor cursor = dbHelper.getAllNamad(
(constraint != null ? constraint.toString() : null));
startManagingCursor(cursor);
cursor.moveToFirst();
return cursor;
}
});

I have been working on an app that requires me to get information such as a Place Name and a PLace Photo from google PLaces Api and set it into a RecyclerView. I am stuck because I managed to get the code to work with no errors but the RecyclerView is empty. What is wrong with my code?
I am stuck because I don't know where the problem is. When I run the code, all the fetchs work and the tags show up in the Log so I am completely lost. My first thought is that I am displaying the code wrong but then I have no recourse to step forward and change it to something else because I am not sure if it would be better or worse.
This is the Fragment for the RecyclerView Item:
public class VenueList extends Fragment{
ArrayList<VenueItem> vIL = new ArrayList<>();
private PlacesClient placesClient;
private Context contextForPlaces;
place ids for the places I am currently using
String[] clubs = {"ChIJO_uSYKNZwokRAC7RLeB0oZ8", "ChIJAQBEylJYwokRLbnrAchQImk",
"ChIJU_26rfpYwokRTNf2K1-7p8E", "ChIJ38hxfnhZwokRx1HSFLj790w", "ChIJBwnlGrdZwokRpf61pMm860c"

"ChIJ6bU_E4ZZwokR2ZDbY_IhhrI"};
#Override
public void onAttach(Context context) {
super.onAttach(context);
contextForPlaces = context;
}
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.menu_venue, container, false);
RecyclerView vRV = view.findViewById(R.id.view_venue);
List<Place.Field> placeFields = Arrays.asList(Place.Field.NAME, Place.Field.PHOTO_METADATAS);
if (!Places.isInitialized()) {
Places.initialize(contextForPlaces, "AIzaSyCKGd3fqmtsDklRGMhnkuIy1GS-j6gRBh8");}
placesClient = Places.createClient(contextForPlaces);
vRV.setHasFixedSize(true);
RecyclerView.LayoutManager vLM = new LinearLayoutManager(this.getActivity());
RecyclerView.Adapter vAdapter = new VenueAdapter(vIL);
// run through each photo to make sure it has a place attached to it then insert each photo and place into the vIL
//createBitmap for fetchPhoto
for (String club : clubs) {
FetchPlaceRequest request = FetchPlaceRequest.newInstance(club, placeFields);
placesClient.fetchPlace(request).addOnSuccessListener((response) -> {
Place place = response.getPlace();
PhotoMetadata photoMetadata = place.getPhotoMetadatas().get(0);
String attributions = photoMetadata.getAttributions();
FetchPhotoRequest photoRequest = FetchPhotoRequest.builder(photoMetadata).setMaxHeight(200).build();
placesClient.fetchPhoto(photoRequest).addOnSuccessListener((fetchPhotoResponse) -> {
Bitmap bitmap = fetchPhotoResponse.getBitmap();
vIL.add(new VenueItem(/*Photo*/bitmap, place/*Name*/));
Log.i(TAG, "Photo Should Be Up: ");
}).addOnFailureListener((exception) -> {
if (exception instanceof ApiException) {
ApiException apiException = (ApiException) exception;
int statusCode = apiException.getStatusCode();
// Handle error with given status code.
Log.e(TAG, "Place not found: " + exception.getMessage());
}
});
Log.i(TAG, "Place found: " + place.getName());
}).addOnFailureListener((exception) -> {
if (exception instanceof ApiException) {
ApiException apiException = (ApiException) exception;
int statusCode = apiException.getStatusCode();
// Handle error with given status code.
Log.e(TAG, "Place not found: " + exception.getMessage());
}
});
}
vRV.setLayoutManager(vLM);
vRV.setAdapter(vAdapter);
return view;
}
This is the part of the RecyclerView Adapter I changed. I used to be a getResourse for the image because the image was from the drawable folder
public void onBindViewHolder(#NonNull VenueViewHolder venueViewHolder, int i) {
VenueItem currentItem = vIAL.get(i);
if(currentItem.getVenueImageResource() == null){
venueViewHolder.vIV.setImageResource(R.drawable.ic_android);
}else
venueViewHolder.vIV.setImageBitmap(currentItem.getVenueImageResource());
venueViewHolder.vTV.setText((CharSequence) currentItem.getVenueDescription());
}
The Item itself which I also had to change a bit from its original. I made the string a Place and the int a Bitmap. I thought that would work.
public class VenueItem {
private Bitmap venueImageResource;
private Place venueDescription;
public VenueItem(Bitmap vIR, Place description) {
venueImageResource = vIR;
venueDescription = description;
}
public Bitmap getVenueImageResource() {
return venueImageResource;
}
public Place getVenueDescription() {
return venueDescription;
}
}
I want to be able to request a place name and a photo of the place using the placesClient and precent it in the for of a RecyclerView. I know the place Ids are correct because the Log returns the names of all the places. But they do not show up on the RecyclerView
I figured out the answer myself.
vRV.setLayoutManager(vLM);
vRV.setAdapter(vAdapter);
I just had to put these two lines into the for loop under the list item so that each item could escape before meing erased
I am building an android application that shows autocomplete feature and fetches autocomplete predictions in google maps using - GeoDataApi.getAutocompletePredictions. I followed this tutorial - https://github.com/googlesamples/android-play-places/blob/master/PlaceComplete/Application/src/main/java/com/example/google/playservices/placecomplete/PlaceAutocompleteAdapter.java
But somehow this is not working fine for me.
My class is this -
public class GooglePlacesAutoCompleteAdapter extends ArrayAdapter implements Filterable {
private ArrayList<PlaceAutocomplete> mResultList;
GoogleApiClient mGoogleApiClient;
private LatLngBounds mBounds;
private AutocompleteFilter mPlaceFilter;
int radius = 500;
public GooglePlacesAutoCompleteAdapter(Context context, int textViewResourceId, GoogleApiClient googleApiClient,
Location lastLocation, AutocompleteFilter filter) {
super(context, textViewResourceId);
LatLng currentLatLng = new LatLng(lastLocation.getLatitude(), lastLocation.getLongitude());
mBounds = Utility.boundsWithCenterAndLatLngDistance(currentLatLng, 500, 500);
mGoogleApiClient = googleApiClient;
mPlaceFilter = filter;
}
#Override
public int getCount() {
return mResultList.size();
}
#Override
public PlaceAutocomplete getItem(int index) {
return mResultList.get(index);
}
#Override
public android.widget.Filter getFilter() {
Filter filter = new Filter() {
#Override
public FilterResults performFiltering(CharSequence constraint) {
FilterResults filterResults = new FilterResults();
if (constraint != null && constraint.length() > 3 && constraint.length()%3 == 1) {
// Retrieve the autocomplete results.
mResultList = autocomplete(constraint.toString());
// Assign the data to the FilterResults
filterResults.values = mResultList;
filterResults.count = mResultList.size();
}
return filterResults;
}
#Override
public void publishResults(CharSequence constraint, FilterResults results) {
if (results != null && results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
};
return filter;
}
public ArrayList<PlaceAutocomplete> autocomplete(String input) {
if (mGoogleApiClient.isConnected()) {
// Submit the query to the autocomplete API and retrieve a PendingResult that will
// contain the results when the query completes.
PendingResult results = Places.GeoDataApi.getAutocompletePredictions(mGoogleApiClient, input.toString(),
mBounds, mPlaceFilter);
// This method should have been called off the main UI thread. Block and wait for at most 60s
// for a result from the API.
AutocompletePredictionBuffer autocompletePredictions = (AutocompletePredictionBuffer)results.await(60, TimeUnit.SECONDS);
// Confirm that the query completed successfully, otherwise return null
final Status status = autocompletePredictions.getStatus();
if (!status.isSuccess()) {
//Toast.makeText(getContext(), "Error contacting API: " + status.toString(),Toast.LENGTH_SHORT).show();
//Log.e(TAG, "Error getting autocomplete prediction API call: " + status.toString());
autocompletePredictions.release();
return null;
}
// Copy the results into our own data structure, because we can't hold onto the buffer.
// AutocompletePrediction objects encapsulate the API response (place ID and description).
Iterator<AutocompletePrediction> iterator = autocompletePredictions.iterator();
ArrayList resultList = new ArrayList<>(autocompletePredictions.getCount());
while (iterator.hasNext()) {
AutocompletePrediction prediction = iterator.next();
// Get the details of this prediction and copy it into a new PlaceAutocomplete object.
resultList.add(new PlaceAutocomplete(prediction.getPlaceId(), prediction.getDescription()));
}
// Release the buffer now that all data has been copied.
autocompletePredictions.release();
return resultList;
}
//Log.e(TAG, "Google API client is not connected for autocomplete query.");
return null;
}
class PlaceAutocomplete {
public CharSequence placeId;
public CharSequence description;
PlaceAutocomplete(CharSequence placeId, CharSequence description) {
this.placeId = placeId;
this.description = description;
}
#Override
public String toString() {
return description.toString();
}
}
}
The line on which GeoDataApi.getAutocompletePredictions is called, goes into an internal classes called - Filter.java, Log.java, handler.java and then Looper.java and loops there indefinetly on line 121 of Looper.java (I am sure studio sdk will show the code for Looper.java).
It is not even throwing an error, or going to the next line, it just does not work. Plus, I am not able to see the stack trace of an error.
This is the code snippet which is calling this -
if (mLastLocation != null) {
GooglePlacesAutoCompleteAdapter placesAdapter = new GooglePlacesAutoCompleteAdapter(this, R.layout.item_list, mGoogleApiClient, mLastLocation, null);
autoCompView.setAdapter(placesAdapter);
autoCompView.setOnItemClickListener(this);
}
Can someone please tell me what I am doing wrong here? Please any help will be greatly appreciated. I need to get this working as soon as I could.
PS - I am passing mPlaceFilter as null here.

i want to create some highchart widget by Eclipse RAP ,and i follow the official guide like this

}
// //////////////////
// overwrite methods
#Override
public void setLayout(Layout layout) {
throw new UnsupportedOperationException("Cannot change internal layout of CkEditor");
}
}
the error is occur:
Uncaught Error: Operation "create" on target "r6" of type "null" failed:

Properties:

and i have a question about this , what differents from extends Canvas and Composite;
You forget to implement setters in your javascript code.
The created object is stored by the framework under its object id. This object has to implement setter methods that match the properties defined in the handler, which will then be called when the server sends a set operation for a given property.
I am using Google cloud end point for my rest service. I am consuming this data in a GWT web client using RestyGWT.
I noticed that cloud end point is automatically enclosing a long datatype in double quotes which is causing an exception in RestyGWT when I try to convert JSON to POJO.
Here is my sample code.
#Api(name = "test")
public class EndpointAPI {
#ApiMethod(httpMethod = HttpMethod.GET, path = "test")
public Container test() {
Container container = new Container();
container.testLong = (long)3234345;
container.testDate = new Date();
container.testString = "sathya";
container.testDouble = 123.98;
container.testInt = 123;
return container;
}
public class Container {
public long testLong;
public Date testDate;
public String testString;
public double testDouble;
public int testInt;
}
}
This is what is returned as JSON by cloud end point. You can see that testLong is serialized as "3234345" rather than 3234345.
I have the following questions.
(1) How can I remove double quotes in long values ?
(2) How can I change the string format to "yyyy-MMM-dd hh:mm:ss" ?
Regards,
Sathya
What version of restyGWT are you using ? Did you try 1.4 snapshot ?
I think this is the code (1.4) responsible for parsing a long in restygwt, it might help you :
public static final AbstractJsonEncoderDecoder<Long> LONG = new AbstractJsonEncoderDecoder<Long>() {
public Long decode(JSONValue value) throws DecodingException {
if (value == null || value.isNull() != null) {
return null;
}
return (long) toDouble(value);
}
public JSONValue encode(Long value) throws EncodingException {
return (value == null) ? getNullType() : new JSONNumber(value);
}
};
static public double toDouble(JSONValue value) {
JSONNumber number = value.isNumber();
if (number == null) {
JSONString val = value.isString();
if (val != null){
try {
return Double.parseDouble(val.stringValue());
}
catch(NumberFormatException e){
// just through exception below
}
}
throw new DecodingException("Expected a json number, but was given: " + value);
}
return number.doubleValue();
}
Got it working - Posted My solution below but will like to know if there is better way
Hello All
I am trying to create Domain Event for a newly created (after migration) domain object in my database.
for Objects without any internal child objects it worked fine by using Script Component. The problem is in how to get the child rows to add information to event object.
Ex. Customer-> Customer Locations.
I am creating Event in Script Component- as tranformation- (have reference to my Domain event module) and then creating sending serialized information about event as a column value. The input rows currently provide data for the parent object.
Please advise.
Regards,
The Mar
Edit 1
I would like to add that current I am doing processsing in
public override void Input0_ProcessInputRow(Input0Buffer Row)
I am looking for something like create a a data reader in this function
loop through data rows -> create child objecta nd add it to parent colelction
Still on google and PreExecute and ProcessInput Seems something to look at .
This is my solution. I am a total newbie in SSIS , so this may not be the best solution.

}
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
Collection<CustomerLocation> locations = new Collection<CustomerLocation>();
cmd.Parameters["CustId"].Value = Row.id;
// Any error always saw that reader reamians open on connection

}

// }
//}
reader.Close();
}
public override void ReleaseConnections()
{
base.ReleaseConnections();
connectionManager.ReleaseConnection(conn);
}
}
One thing to note is that a different approach to create connection is to
get the connection string from connectionManager and use it to create OLEDB connection.
