How do I get the URI of my SQLite database in my Android app?

I开发者_运维知识库 have an Android app with a database called "myTestDB" with a table called "list_items". I want to use the Cursor getContentResolver().query() method to get a cursor to add to a SimpleCursorAdapter. The first argument of the query() method is a URI and I'm not sure what the URI should look like.

You do not use getContentResolver() to access a SQLite database directly. You use getContentResolver() when working with content providers. You call query() on a SQLiteDatabase object to get a Cursor for use with SimpleCursorAdapter.

A database doesn't have a Uri (other than the file where it's located). Data managed through a content provider has one. If you want to use the content resolver to perform a query, you need to write a content provider first.

If you don't want to do that, simply use SQLiteDatabase's query function - it returns a Cursor that you can pass to the SimpleCursorAdapter.

it is fairly straightforward Method call looks like this

mDataBase.query(TABLE_NAME, columns, null, null, null, null, null);

where, TABLE_NAME = your SQLite table name and columns is a string array like

String columns[] = new String[] { "Column1" };

If you want all columns, you can pass null for second argument.

Correction: As mentioned by a few others, there is no URI.
