用Android Content Provider插入一行

Question

我有下一个内容提供者要在表AGENDA中插入一行，执行以下命令:

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

，一切都很好。

但是现在，我想使用带有议程insertwithconflict的uri来插入一行。请问，我怎样修改线路?

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

去做?

这是我的提供商:

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;
    }
}

Answer 1

做如下修改，请根据需要使用命名约定。

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

调用机制

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