    <p>I'm getting a NullPointerException while attempting to create a Spinner within a dialog and can't seem to debug it because the code looks solid. Wonder if anyone else has any idea. Any help is greatly appreciated.</p> <pre><code> protected Dialog onCreateDialog(int id) { Dialog dialog; switch(id) { case DIALOG_SEND_PM: Spinner spinner = (Spinner)findViewById(R.id.pm_server); ArrayAdapter&lt;CharSequence&gt; adapter = ArrayAdapter.createFromResource(this, R.array.server_array, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); spinner.setOnItemSelectedListener(new MyOnItemSelectedListener()); dialog = new Dialog(PM.this); dialog.setContentView(R.layout.send_pm_dialog); dialog.setTitle(R.string.send_pm); pmMessage = (EditText) dialog.findViewById(R.id.send_pm_box); Button sendPm = (Button) dialog.findViewById(R.id.send_pm_button); sendPm.setOnClickListener(PM.this); break; default: dialog = null; } </code></pre> <p>I get the exception at adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); I changed the context to MyClass.this and the exception moved down to the next line, which confuses me. I'm wondering if it is the adapter having a null value but I call everything the same way I have before while not in a dialog.</p> <p>Relevant XML data:</p> <pre><code>&lt;LinearLayout&gt; &lt;TextView/&gt; &lt;LinearLayout&gt; &lt;TextView/&gt; &lt;EditText/&gt; &lt;TextView/&gt; &lt;Spinner android:id="@+id/pm_server" android:layout_height="fill_parent" android:layout_width="wrap_content" android:background="@drawable/yblueborder" android:textColor="#ABABAB"/&gt; &lt;/LinearLayout&gt; &lt;Button/&gt; &lt;/LinearLayout&gt; </code></pre> <p>Edited out the rest of the data so it wouldn't take up too much space.</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.
