    <p>I have created an <em>DialogFragment</em> which is building and returning <em>AlertDialog</em> from <em>onCreateDialog</em> method. The AlertDialog contains two EditText views. </p> <p>I'm setting the initial values of these two edit texts in the <em>onCreateDialog</em> method which works great until I rotate the phone and all changes get lost/restored to initial values because the <em>onCreateDialog</em> is recalled. </p> <p>So my question is where should I place the initial values so they are only set the very first time you open the dialog and if you have done changes and you rotate your phone, the last state i retained and retached?</p> <p>Below I have pasted simplified version of my code. One solution could be initializing the class attributes at newInstance() method, but then I need to make them static. Other solution could be passing the values through the Bundle, but no put-methods take Calendar as parameter type. </p> <p>What is best practice?</p> <pre><code>public class MyDialogFragment extends DialogFragment implements OnClickListener, OnDateSetListener, OnQuantitySetListener { private EditText editText1, editText2 private MyObject myObject; public static MyDialogFragment newInstance() { return new MyDialogFragment (); } @Override public Dialog onCreateDialog(Bundle savedInstanceState) { LayoutInflater factory = LayoutInflater.from(getActivity()); final View v = factory.inflate(R.layout.my_layout, null); editText1 = (EditText) v.findViewById(R.id.text1); editText2 = (EditText) v.findViewById(R.id.text2); myObject = &lt;get the object from database&gt;; editText1.setText(myObject.attribute1); editText2.setText(myObject.attribute2); bindDataToViews(); return new AlertDialog.Builder(getActivity()) .setIconAttribute(R.drawable.add) .setTitle("Title of the dialog") .setView(v)).create(); } ... other methods using getting the values from EditText and putting them back to MyObject </code></pre> <p>}</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.
