Here is my code:
public class TasksList extends ListActivity {
...
private static final int COLUMNS_DIALOG = 7;
private static final int ORDER_DIALOG = 8;
...
/**
* @see android.app.Activity#onCreateDialog(int)
*/
@Override
protected Dialog onCreateDialog(int id) {
Dialog dialog;
final String[] columns;
Cursor c = managedQuery(Tasks.CONTENT_URI, null, null, null, null);
columns = c.getColumnNames();
final String[] order = { "Ascending", "Descending" };
switch (id) {
case COLUMNS_DIALOG:
AlertDialog.Builder columnDialog = new AlertDialog.Builder(this);
columnDialog.setSingleChoiceItems(columns, -1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
bundle.putString("column", columns[which]);
}
});
dialog = columnDialog.create();
case ORDER_DIALOG:
AlertDialog.Builder orderDialog = new AlertDialog.Builder(this);
orderDialog.setSingleChoiceItems(order, -1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String orderS;
if (order[which].equalsIgnoreCase("Ascending"))
orderS = "ASC";
else
orderS = "DESC";
bundle.putString("order", orderS);
}
});
dialog = orderDialog.create();
default:
dialog = null;
}
return dialog;
}
/**
* @see android.app.Activity#onOptionsItemSelected(android.view.MenuItem)
*/
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case SORT_MENU:
showDialog(COLUMNS_DIALOG);
showDialog(ORDER_DIALOG);
String orderBy = bundle.getString("column") + bundle.getString("order");
Cursor tasks = managedQuery(Tasks.CONTENT_URI, projection, null, null, orderBy);
adapter = new TasksAdapter(this, tasks);
getListView().setAdapter(adapter);
break;
case FILTER_MENU:
break;
}
return false;
}
The showDialog doesn't display the dialog. I used the Debugger and it does executes these statements, but the dialog doesn't show.
}
