    <p>I'm developing an Android 2.2 app.</p> <p>I use a dialog to ask user for his nickname. This is my source code:</p> <pre><code>private void showDialog() { //set up dialog final Dialog dialog = new Dialog(UserStatsActivity.this); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.setContentView(R.layout.createuserrow); dialog.setOnDismissListener(this); //set up button Button button = (Button) dialog.findViewById(R.id.saveUser); button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { TextView nameTextView = (TextView)dialog.findViewById(R.id.userName); userNickName = nameTextView.getText().toString().trim(); if ((userNickName.length() &gt; 0) &amp;&amp; (userNickName.length() &lt; 9)){ saveUser = true; dialog.dismiss(); } } }); //now that the dialog is set up, it's time to show it dialog.show(); } public void onDismiss(DialogInterface arg0) { try { if (saveUser) { SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext()); User.saveUser(getApplicationContext(), userNickName); Editor editor = prefs.edit(); editor.putString(USER_NAME, userNickName); editor.putBoolean(FIRST_TIME_RUN, false); editor.commit(); loadPreferences(); } } catch (Exception ex){ Log.e(Constants.APP_TAG, "UActivity: " + ex.getMessage()); showAlert(this.getString(R.string.errorClose)); } } </code></pre> <p>If I press home key while dialog is shown. When I start app again, and I click on save button, dialog is shown again.</p> <p>I've debug my code and it is working perfectly, but the dialog is still open.</p> <p>What's happening?</p> <p>Thanks.</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.
