    <p>I want to show the month i have chosen in a textview. To do this i have a spinner, and when i select a month in the spinner this should find all the data i have for this specific month. I am not sure of how to filter the query with a variable, or how to pass the variable from my Start.java class to my KilometerSQL.java class.</p> <p>Since I'm not using a intent to go to the Kilometer.java class i don't know how i can pass the variable.</p> <p>Here is my Start.java class</p> <pre><code>@Override public void onItemSelected(AdapterView&lt;?&gt; parent, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub String month = parent.getSelectedItem().toString(); //This is my month variable KilometerSQL spinner = new KilometerSQL(this); spinner.open(); String dataSpinner = KilometerSQL.spinnerData(); spinner.close(); logbog.setText(dataSpinner); } </code></pre> <p>And here is my KilometerSQL.java class</p> <pre><code>public static String spinnerData() { // TODO Auto-generated method stub String [] columns = new String []{ KEY_DAY, KEY_MONTH, KEY_YEAR, KEY_KILOMETER, KEY_LOCATIONS}; Cursor c = ourDatabase.query(DATABASE_TABLE, columns, KEY_MONTH, null, null, null, null); String result = ""; int iDay = c.getColumnIndex(KEY_DAY); int iMonth = c.getColumnIndex(KEY_MONTH); int iYear = c.getColumnIndex(KEY_YEAR); int iKilometer = c.getColumnIndex(KEY_KILOMETER); int iLocations = c.getColumnIndex(KEY_LOCATIONS); for (c.moveToFirst();!c.isAfterLast();c.moveToNext()){ result = result + c.getString(iDay) + "-" + c.getString(iMonth) + "-" + c.getString(iYear) + " " + c.getString(iKilometer) + " " + c.getString(iLocations) + "\n"; } return result; } </code></pre> <p>I haven't had any luck using answers similar to mine from other users.</p> <p>All help is appreciated.</p>

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.
