    <p>I have a database and I am doing a query to it using</p> <p><code>Cursor mCursor = mapDb.query(MY_TABLE, new String[] {KEY_ONEID, KEY_TWOID}, "trim("+KEY_TWOID + ") != '' ", null, null, null, null);</code></p> <p>which in SQL terms literally means: <code>SELECT OneId, TwoId FROM auth WHERE trim(TwoId) != ''</code></p> <p>Using the raw SQL query this works in my SQLite browser to show me the rows in question, so the Cursor object should contain the same results.</p> <p>Secondly in my java method I am using a condition to check if this result has anything</p> <pre><code> if(mCursor.getColumnIndex(KEY_ONEID) &gt; -1) //if &gt; -1 then the mCursor returned a row { if(mCursor.getString(mCursor.getColumnIndex(KEY_ONEID)).contains(id)) //breaks here return mCursor.getString(mCursor.getColumnIndex(KEY_TWOID)); else return ""; } </code></pre> <p>But for some reason, even though the mCursor hashmap should have all the values returned, this next conditional statement</p> <p><code>mCursor.getString(mCursor.getColumnIndex(KEY_ONEID)).contains(id)</code></p> <p>still returns: <code>An exception occurred: android.database.CursorIndexOutOfBoundsException</code></p> <p>this is the line that throws the exception: <code>mCursor.getString(mCursor.getColumnIndex(KEY_ONEID))</code> and so does my next item in the return statement</p> <p>I'm baffled at how to retrieve a particular row value then! because I have pulled the database and run the same query and can clearly see that both of the values I want, do in fact exist!</p> <p>the Cursor function doesn't provide many other ways to retrieve values, so insight appreciated!</p>

    1. COby the way I have coded a lightweight ORM framework for Android. https://github.com/ahmetalpbalkan/orman you can use it for such things. It handles all the cursor cases and you don't see any cursors or SQLs at all. It can give you desired column_name:row pair. let me know if you want to use.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
