    <p>My issue today is related to a custom <code>SimpleCursorAdapter</code> I've implemented. Here are my activities <code>onCreate()</code> and the custom <code>SimpleCursorAdapter</code> :</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); customSharedPreference = getSharedPreferences("myCustomSharedPrefs", Activity.MODE_PRIVATE); editor = customSharedPreference.edit(); setContentView(R.layout.activity_1); op = new OperationsClass(getApplicationContext()); op.open(); Cursor cursor = op.getList(); startManagingCursor(cursor); String[] columns = new String[] { "AAA", "BBB", "CCC"}; int[] to = new int[] { R.id.entry_aaa,R.id.entry_bbb, R.id.entry_ccc}; MyCursorAdapter mAdapter = new MyCursorAdapter(this, R.layout.custom_entry, cursor, columns, to); this.setListAdapter(mAdapter); op.close(); } </code></pre> <p><code>OperationsClass</code> manages a database and the <code>getList(</code>) function returns a cursor of the entries.</p> <pre><code>public class MyCursorAdapter extends SimpleCursorAdapter{ private Context context; private MyCursorAdapter here = this; private int layout; public MyCursorAdapter (Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout; } @Override public View newView(final Context context, Cursor cursor, ViewGroup parent) { Cursor c = getCursor(); final LayoutInflater inflater = LayoutInflater.from(context); View v = inflater.inflate(layout, parent, false); int col1 = c.getColumnIndex("aaa"); String name1 = c.getString(col1 ); int col2 = c.getColumnIndex("bbb"); String name2 = c.getString(col2 ); int col3 = c.getColumnIndex("ccc"); int name3 = c.getInt(col3 ); final TextView text1 = (TextView) v.findViewById(R.id.entry_aaa); final TextView text2 = (TextView) v.findViewById(R.id.entry_bbb); final TextView text3 = (TextView) v.findViewById(R.id.entry_ccc); text1.setText(name); text2.setText(name2); if (name3 == 0) text3.setText("Not checked"); else { text3.setText("Checked"); text3.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { text3.setText("Not checked"); // Here I would like to update my DB using // OperationsClass and the SharedPrefs, // and refresh the ListView with the new // text value. } }); } } return v; } @Override public void bindView(View v, final Context context, Cursor c) { // Same operations as higher } } </code></pre> <p>Basically what I want to achieve is to refresh the <code>ListView</code> when the users clicks on the third column, which means its value changes (has been clicked or has not been). In the same time I wish to update the DB and the <code>SharedPreferences</code>(I could create a new object of both classes and recover from the application context, but that seems pretty heavy).</p> <hr> <p>I also wish to know if there is a way to trigger one of the implemented methods in one activity when an <code>AlertDialog</code> has been opened (in the same app, I actually want to add an element to my database through an <code>AlertDialog</code> and make the Activity that popped it up retrieve a new cursor and refresh its List).</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.

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