    <p>To save selections make a method saveSelections and call it in <code>onPause()</code> and <code>onDestroy()</code>, or create a Button to do the same for you... Edit: </p> <p>Since you are using a <code>ListView</code> which is MultipleChoice I suppose you can do this in onCreate...</p> <pre><code>listView = (ListView) findViewById(R.id.list); listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); listView.setAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_multiple_choice, android.R.id.text1, names)); </code></pre> <p>Create these three methods outside onCreate()</p> <pre><code>private void LoadSelections() { SharedPreferences sp = getPreferences(MODE_PRIVATE); if (sp.contains(LOAD_LIST)) { String savedItems = sp.getString(LOAD_LIST, ""); this.selectedItems.addAll(Arrays.asList(savedItems.split(","))); int count = this.listView.getAdapter().getCount(); for (int i = 0; i &lt; count; i++) { String currentItem = (String) listView.getAdapter().getItem(i); if (this.selectedItems.contains(currentItem)) { this.listView.setItemChecked(i, true); } } } } public void SaveSelections() { SharedPreferences sp = getPreferences(MODE_PRIVATE); SharedPreferences.Editor prefEditor = sp.edit(); String savedItems = getSavedItems(); prefEditor.putString(LOAD_LIST, savedItems); prefEditor.commit(); } private String getSavedItems() { String savedItems = ""; int count = listView.getAdapter().getCount(); for (int i = 0; i &lt; count; i++) { if (listView.isItemChecked(i)) { if (savedItems.length() &gt; 0) { savedItems += "," + listView.getItemAtPosition(i); } else { savedItems += listView.getItemAtPosition(i); } } } return savedItems; } </code></pre> <p>Then in onPause(), do this:</p> <pre><code>@Override protected void onPause() { SaveSelections(); super.onPause(); } </code></pre> <p>Then finally in onCreate call this..</p> <pre><code>LoadSelections(); </code></pre>

    2. COI gave you an abstract idea as to what you can do, you will have to do every thing I said in an Activity where you set the Adapter, follow this approach, it will solve your problem.

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).
