Inserting a row with Android Content Provider


I have the next Content Provider To insert a row in Table AGENDA, I do:

 ContentValues values = new ContentValues(1);
 values.put("MSG", "test");
  context.getContentResolver().insert(DataProvider.CONTENT_URI_AGENDA, values);

and all works well.

But now, I´d like to use the uri with AGENDA_INSERTWITHCONFLICT to insert a row. Please, How can I modify the line :

context.getContentResolver().insert(DataProvider.CONTENT_URI_AGENDA, values);

to do it?

Here is my Provider:

public class DataProvider extends ContentProvider {
    public static final String TAGPROVIDER = "net.techabout.medappointment.provider";
    public static final Uri CONTENT_URI_AGENDA = Uri.parse("content://"+TAGPROVIDER+"/agenda");

    public static final String TABLE_AGENDA = "agenda";

    private DbHelper dbHelper;

    private static final int AGENDA_ALLROWS = 5;
    private static final int AGENDA_INSERTWITHCONFLICT=7;

    private static final UriMatcher uriMatcher;

    static {
        uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
        uriMatcher.addURI(TAGPROVIDER, "agenda", AGENDA_ALLROWS);
        uriMatcher.addURI(TAGPROVIDER, "agenda", AGENDA_INSERTWITHCONFLICT);
    }

    @Override
    public Uri insert(Uri uri, ContentValues values) {
        SQLiteDatabase db = dbHelper.getWritableDatabase();

        long id;
        switch (uriMatcher.match(uri)) {
            case AGENDA_ALLROWS:
                id = db.insertOrThrow(TABLE_AGENDA, null, values);
                break;
            case AGENDA_INSERTWITHCONFLICT:
                  id=db.insertWithOnConflict(TABLE_AGENDA, BaseColumns._ID, values, SQLiteDatabase.CONFLICT_REPLACE);
                  break;

            default:
                throw new IllegalArgumentException("Unsupported URI: " + uri);
        }

        Uri insertUri = ContentUris.withAppendedId(uri, id);
        getContext().getContentResolver().notifyChange(insertUri, null);
        return insertUri;
    }

}

Solution

  • make following changes, Please use naming convetions as required.

    // content provider
    static {
        uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
        uriMatcher.addURI(TAGPROVIDER, "agenda", AGENDA_ALLROWS);
        uriMatcher.addURI(TAGPROVIDER, "agenda_insert_conflicts", AGENDA_INSERTWITHCONFLICT);
    }
    

    calling mechanism

     String URL = "net.techabout.medappointment.provider/agenda_insert_conflicts";
    
      Uri uri = Uri.parse(URL);
    context.getContentResolver().insert(uri , values);
