    <p>In my Navigation Drawer I have a problem, when it loads anything in the first spot will crash the app, so my solution to this is to set it to a string that changes to say "(appname) Free" or " (appname) Premium", depending on if the premium upgrade was purchased. </p> <p>I would like this unclickable as it is currently able to be clicked but nothing happens. Ideally this would be a submenu, or title, but I could not figure out how to implement that. Here is a excerpt of my code:</p> <pre><code>public class myClass extends SherlockActivity implements OnItemSelectedListener { private DrawerLayout mDrawerLayout; private ListView mDrawerList; private ActionBarDrawerToggle mDrawerToggle; private CharSequence mDrawerTitle; private CharSequence mTitle; private String[] mPlanetTitles; @SuppressLint("NewApi") @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.mylayout); mTitle = mDrawerTitle = getTitle(); if (mIsPremium == true) { mPlanetTitles = getResources().getStringArray( R.array.planets_array_prem); } else { mPlanetTitles = getResources() .getStringArray(R.array.planets_array); } mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mDrawerList = (ListView) findViewById(R.id.left_drawer); // set a custom shadow that overlays the main content when the drawer // opens mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); // set up the drawer's list view with items and click listener mDrawerList.setAdapter(new ArrayAdapter&lt;String&gt;(this, R.layout.drawer_list_item, mPlanetTitles)); mDrawerList.setOnItemClickListener(new DrawerItemClickListener()); // enable ActionBar app icon to behave as action to toggle nav drawer getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setHomeButtonEnabled(true); // ActionBarDrawerToggle ties together the the proper interactions // between the sliding drawer and the action bar app icon mDrawerToggle = new ActionBarDrawerToggle(this, /* host Activity */ mDrawerLayout, /* DrawerLayout object */ R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */ R.string.drawer_open, /* "open drawer" description for accessibility */ R.string.drawer_close /* "close drawer" description for accessibility */ ) { public void onDrawerClosed(View view) { getSupportActionBar().setTitle(mTitle); supportInvalidateOptionsMenu(); // creates call to // onPrepareOptionsMenu() } public void onDrawerOpened(View drawerView) { getSupportActionBar().setTitle(mDrawerTitle); supportInvalidateOptionsMenu(); // creates call to // onPrepareOptionsMenu() } }; mDrawerLayout.setDrawerListener(mDrawerToggle); if (savedInstanceState == null) { selectItem(0); } } /* The click listener for ListView in the navigation drawer */ private class DrawerItemClickListener implements ListView.OnItemClickListener { public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { switch (position) { case 0: /* * Toast.makeText( getApplicationContext(), * "case 0 - A Activity.", Toast.LENGTH_LONG).show(); Intent * c0 = new Intent(getBaseContext(), * activity.class); startActivity(c0); */break; case 1: Toast.makeText(getApplicationContext(), "case 1 - B Activity", Toast.LENGTH_LONG).show(); Intent c1 = new Intent(getBaseContext(), ActivityB.class); startActivity(c1); break; default: } } } public void selectItem(int position) { switch (position) { case 0: // setContentView(R.layout.main); break; case 1: setContentView(R.layout.main); break; default: } } @Override public void setTitle(CharSequence title) { mTitle = title; getSupportActionBar().setTitle(mTitle); } /** * When using the ActionBarDrawerToggle, you must call it during * onPostCreate() and onConfigurationChanged()... */ @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); // Sync the toggle state after onRestoreInstanceState has occurred. mDrawerToggle.syncState(); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); // Pass any configuration change to the drawer toggls mDrawerToggle.onConfigurationChanged(newConfig); } </code></pre> <p>I do not use fragments, I was going to implement the navigation drawer by doing on click and moving to new activities. I am looking for a solution to my primary problem but would welcome any design tips.</p> <p>Thank you</p> <p><em>Edit</em></p> <p>With CommonsWare's help I developed this: but nothing is different in my application. I want the first time (case 0 (position 0)) to be disabled. </p> <pre><code>public class MyArrayAdapter extends ArrayAdapter&lt;String&gt; { public MyArrayAdapter(Context context, int position) { super(context, 0); } public boolean areAllItemsEnabled() { return false; } public boolean isEnabled(int position) { if (position == 0) { return false; } else { return true; } } } </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.
