    data
    text
    <p>I have two elements:</p> <ol> <li>Spinner INSIDE THE ACTIONBAR (HoloEverywhere (support.v7)) of my Activity set with an <code>onItemSelectedListener()</code>.</li> <li>Listview in my Activity which is filled with an ArrayAdapter</li> </ol> <p>When I choose an Item from the Spinner, the ListView should be updated. But somehow there is a problem with my Spinner I guess. The ListView first updates when I clicked in a TextField of my Activity after I choose a SpinnerItem.</p> <p>My code:</p> <pre><code>// Get a databaseConnection and fills the history variable with the data of // the selected spinnerItem "history" is right filled with all Strings for // the chosen Spinner from the database -&gt; works correct public void updateHistory() { sqlLightDatabase database = new sqlLightDatabase(this); ArrayList&lt;String&gt; history = database.getArrayList( mySpinner.getSelectedItem().toString()); // set the adapter to the ListView ArrayAdapter&lt;String&gt; listenAdapter = new ArrayAdapter&lt;String&gt;(this, R.layout.list_item, history); myListView.setAdapter(listenAdapter); // the code works through, but the ListView is not shown the update // instantly. But now, when I click a TextField in my Activity, myListView // shows the new data } // Is instantly called when an Item is selected in mySpinner (in my ActionBar) @Override public void onItemSelected(AdapterView&lt;?&gt; parent, View view, int position, long id) { // the updateHistory function is called but myLitstView doesn't get // updated with new Data updateHistory(); //Just for testing. The following is working instantly fine. drivenDistance_TF.setText("History changed"); } </code></pre> <p>I tried the last two days to fix this issue, but I have absolute no idea what I could else try to get the ListView instantly updated.</p> <p>There is no ErrorLog, because there are no errors.</p>

    2. COHey. Sorry, this is also not working. What I found out is that this problem just occurs on older SDK's.

Guidance
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.

SQuiL has stopped working due to an internal error.

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