Whenever I push ok button without giving any inputs, the program crashes.I tried to print the values as well, but it didnt display in logcat.Am i doing anything wrong?</p> <pre><code> private void add() { LayoutInflater inflater=LayoutInflater.from(this); final View addView=inflater.inflate(R.layout.add_country, null); new AlertDialog.Builder(this) .setTitle("Add new country/year") .setView(addView) .setPositiveButton("OK", new DialogInterface.OnClickListener() { public void onClickDialogInterface dialog,int whichButton) { /* Read alert input */ EditText editCountry =(EditText)addView.findViewById(R.id.editCountry); String country = editCountry.getText().toString(); EditText editYear =(EditText)addView.findViewById(R.id.editYear); int year = Integer.parseInt( editYear.getText().toString() ); if(editCountry.getText().toString().trim().length()&gt;0 &amp;&amp; editYear.getText().toString().trim().length()&gt;0){ /* Open DB and add new entry */ db.open(); db.insertEntry(country,year); /* Create new cursor to update list. Must be possible to handle * in a better way. */ entryCursor = db.fetchAllEntries(); // all country/year pairs adapter = new SimpleCursorAdapter(CountryEditor.this, R.layout.country_row,entryCursor, new String[] {"country", "year"}, new int[] {R.id.country, R.id.year}); setListAdapter(adapter); db.close(); } else{ Toast.makeText(CountryEditor.this, "You need to enter Country AND Year.", Toast.LENGTH_LONG).show(); } } }) .setNegativeButton("Cancel", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog,int whichButton) { // ignore, just dismiss } }) .show(); } </code></pre>

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.
