Answer 1

If anyone is like me trying (and failing) to get this working with getContentResolver().query here how I managed it:

*Updated thanks to comments from @CL and @Wolfram Rittmeyer, as they said this is the same as for rawQuery *

Correct way:

  public static String SELECTION_LIKE_EMP_NAME = Columns.EMPLOYEE_NAME
            + " like ?";            

  Cursor c = context.getContentResolver().query(contentUri,
                PROJECTION, SELECTION_LIKE_EMP_NAME, new String[] { "%" + query + "%" }, null);

Previous answer that was open to SQL injection attack:

public static String SELECTION_LIKE_EMP_NAME = Columns.EMPLOYEE_NAME
            + " like '%?%'";

String selection = SELECTION_LIKE_EMP_NAME.replace("?", query);

Cursor c = context.getContentResolver().query(contentUri,
            PROJECTION, selection, null, null);
