    <p>I wrote a method in my database manager that is suppose to return the total amount of rows in a table called homeIcons; but i noticed that it returns 0 when there are 0, 1 there is 1, and then 10 when there are 3? so something is wrong with my method.. please see below:</p> <pre><code>public int getHomeScreenTotal (){ SQLiteDatabase db=this.getReadableDatabase(); Cursor c = db.rawQuery("select count(*) as count from "+ homeIcons,null); c.moveToFirst(); int total = c.getInt(0); return total; } </code></pre> <p><em>EDIT</em> so i edited my code.. and i have rewritten this method in just about every way possible.. The problem is not that it isn't returning the right amount of rows, because it is.. it is just that it is returning the number in binary.. instead of 3, it returns 11 instead of 5 it returns 101 .. UHG!!!! i just want an int! I can't tell if this is a bug in the adroid/java method for accessing a SQLite DB or if i am missing something.. I have even tried duck punching it to an int, but to no avail.. :(</p> <p><em>EDIT</em> ok i just tried to force the binary to an int using the following method:</p> <pre><code>public int getHomeScreenTotal (){ SQLiteDatabase db=this.getReadableDatabase(); int rows; String bin = ""+ db.compileStatement("SELECT COUNT(*) FROM " + homeIcons).simpleQueryForLong(); rows = Integer.parseInt(bin, 2); return rows; } </code></pre> <p>this throws an Error of </p> <p><em>java.lang.NumberFormatException: Invalid int: "7"</em></p> <p>where the "7" is, is actually the number it is suppose to return.. if i have 5 rows i get an error of Invalid int "5"; ect..</p>

    2. COI should close my cursor correct.. The problem seems to be that the count is long and i need an int.. I tried forcing it as an int but im still getting binary returns like 1, 10,11, 100,101 instead of 1,2, 3,4

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
