    <p>i am using the developer.android Notepad tutorial (<a href="http://developer.android.com/training/notepad/notepad-ex2.html" rel="nofollow">http://developer.android.com/training/notepad/notepad-ex2.html</a>) to create a Noteapp, but i have problems with the onItemClick and i cant figure out, where the problem lies.</p> <p>My Code</p> <pre><code>public class MainActivity extends ListActivity { private static final int ACTIVITY_CREATE=0; private static final int ACTIVITY_EDIT=1; public static final int INSERT_ID = Menu.FIRST; private static final int DELETE_ID = Menu.FIRST + 1; private int mNoteNumber = 1; private NotesDbAdapter mDbHelper; public static String notesstring; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mDbHelper = new NotesDbAdapter(this); mDbHelper.open(); fillData(); registerForContextMenu(getListView()); ImageButton b = (ImageButton) findViewById(R.id.add); b.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { //Intent i = new Intent(MainActivity.this, NoteScreen.class); //startActivity(i); createNote(); } }); } private void fillData() { Cursor c = mDbHelper.fetchAllNotes(); startManagingCursor(c); String[] from = new String[] { NotesDbAdapter.KEY_TITLE }; int[] to = new int[] { R.id.text1 }; SimpleCursorAdapter notes = new SimpleCursorAdapter(this, R.layout.notes_row, c, from, to); setListAdapter(notes); } @Override public boolean onCreateOptionsMenu(Menu menu) { boolean result = super.onCreateOptionsMenu(menu); menu.add(0, INSERT_ID, 0, R.string.menu_insert); MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.mainactivitymenu, menu); return result; } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId() ) { case INSERT_ID: createNote(); return true; } switch (item.getItemId()) { case R.id.action_settings: Intent i = new Intent(MainActivity.this, Settings.class); startActivity(i); return true; /*case R.id.action_new: Intent e = new Intent(MainActivity.this, NoteScreen.class); startActivity(e); return true; */ default: return super.onOptionsItemSelected(item); } } @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); menu.add(0, DELETE_ID, 0, R.string.menu_delete); } @Override public boolean onContextItemSelected(MenuItem item) { switch(item.getItemId()) { case DELETE_ID: AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); mDbHelper.deleteNote(info.id); fillData(); return true; } return super.onContextItemSelected(item); } private void createNote() { Intent i = new Intent (this, NoteScreen.class); startActivityForResult(i, ACTIVITY_CREATE); /*String noteName = "Note " + mNoteNumber++; mDbHelper.createNote(noteName, ""); fillData();*/ } </code></pre> <p>And this is the part where the Errors are:</p> <pre><code>@Override protected void onListItemClick(ListView list, View v, int position, long id) { super.onListItemClick(list, v, position, id); Cursor c = mNotesCurser; c.moveToPosition(position); Intent i = new Intent(this, NoteScreen.class); i.putExtra(NotesDbAdapter.KEY_ROWID, id); i.putExtra(NotesDbAdapter.KEY_TITLE, c.getString( c.getColumnIndexOrThrow(NotesDbAdapter.KEY_TITLE))); i.putExtra(NotesDbAdapter.KEY_BODY, c.getString( c.getColumnIndexOrThrow(NotesDbAdapter.KEY_BODY))); startActivityForResult(i, ACTIVITY_EDIT); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent intent) { super.onActivityResult(requestCode, resultCode, intent); Bundle extras = intent.getExtras(); switch(requestCode) { case ACTIVITY_CREATE: String title = extras.getString(NotesDbAdapter.KEY_TITLE); String body = extras.getString(NotesDbAdapter.KEY_BODY); mDbHelper.createNote(title, body); fillData(); break; case ACTIVITY_EDIT: Long rowId = extras.getLong(NotesDbAdapter.KEY_ROWID); if (rowId != null) { String editTitle = extras.getString(NotesDbAdapter.KEY_TITLE); String editBody = extras.getString(NotesDbAdapter.KEY_BODY); mDbHelper.updateNote(rowId, editTitle, editBody); } fillData(); break; } } </code></pre> <p>}</p> <p>mNotesCurser cannot be resolved to a variable</p> <p>Any idea how to fix this?</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.

SQuiL has stopped working due to an internal error.

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