    <p>I am trying to call "body" and "address" from content://sms/inbox and add them to a ListView.</p> <p>"address" going to the Item1 in the ListView, "body" going to SubItem in same ListView.</p> <p>To do this, I am implementing a Cursor to add these items to the ListView.</p> <p>When running the code how I have it now, I get no errors or crashes, but there is nothing added to my ListView at all. I have all of the permissions needed in the manifest.</p> <p>Not sure where I went wrong :( But thanks in advance!</p> <p>My XML layout:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/header__root" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/black" android:orientation="vertical" &gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@color/burntorange" android:orientation="horizontal" &gt; &lt;TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="147dp" android:layout_height="wrap_content" android:layout_weight="0.13" android:background="@color/burntorange" android:padding="10dp" android:text="Messages" android:textSize="20dp" /&gt; &lt;Button android:id="@+id/bNewMessage" android:layout_width="120dp" android:layout_height="35dp" android:layout_gravity="center" android:layout_margin="4dp" android:background="@color/gray" android:gravity="center" android:onClick="handleClick" android:padding="4dp" android:text="New Thread" android:textColor="@color/white" android:textSize="15dp" /&gt; &lt;/LinearLayout&gt; &lt;ListView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" &gt; &lt;/ListView&gt; &lt;/LinearLayout&gt; </code></pre> <p>My Menu.java:</p> <pre><code>public class Menu extends ListActivity { ListView itemList; @SuppressWarnings("deprecation") @Override public void onCreate(Bundle biscuits) { super.onCreate(biscuits); setContentView(R.layout.header); itemList = (ListView) findViewById(android.R.id.list); Uri uri = Uri.parse("content://sms/inbox"); Cursor c = getContentResolver().query(uri, null, null, null, null); startManagingCursor(c); String[] number = new String [c.getCount()]; String[] body = new String [c.getCount()]; if(c.moveToFirst()){ for (int i=0; i&lt;c.getCount();i++) { body[i]=c.getString(c.getColumnIndexOrThrow("body")).toString(); number[i] =c.getString(c.getColumnIndexOrThrow("address")).toString(); c.moveToNext(); List&lt;Map&lt;String, String&gt;&gt; data = new ArrayList&lt;Map&lt;String, String&gt;&gt;(); Map&lt;String, String&gt; datum = new HashMap&lt;String, String&gt;(2); datum.put("contactNumber", number[i]); datum.put("messagePreview", body[i]); SimpleAdapter adapter = new SimpleAdapter(this, data, android.R.layout.simple_list_item_1, new String[] {"contactNumber", "messagePreview"}, new int [] {android.R.id.text1, android.R.id.text2}); itemList.setAdapter(adapter); } } } public void handleClick(View v) { Intent intent = new Intent(); intent.setClass(this, TextActivity.class); startActivity(intent); } protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); String cheese = (String) l.getItemAtPosition(position); Toast.makeText(this, cheese + " Selected", Toast.LENGTH_SHORT).show(); try { Class ourClass = Class.forName("com.example.mytexts." + cheese); Intent ourIntent = new Intent(Menu.this, ourClass); startActivity(ourIntent); } catch (ClassNotFoundException e) { e.printStackTrace(); } } } </code></pre>

    3. COlog the c.getCount(). you are doing setAdapter inside for loop. You need to do it outside after you have filled the map

Guidance
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).
