    <p>So this is related to a question I asked earlier. I am trying to display an alert using a specified layout. My layout is:</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/layout_root" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"&gt; &lt;TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="fill_parent" android:textColor="#FFF" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>And the code to call and show the alert dialog is:</p> <pre><code> Context mContext = getApplicationContext(); AlertDialog.Builder builder = new AlertDialog.Builder(mContext); // use a custom View defined in xml View view = LayoutInflater.from(mContext).inflate(R.layout.sell_dialog, (ViewGroup) findViewById(R.id.layout_root)); builder.setView(view); builder.setPositiveButton(android.R.string.ok, new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // do whatever you want with the input } }); AlertDialog alertDialog = builder.create(); alertDialog.show(); </code></pre> <p>When I run it I get an error saying:</p> <p>Uncaught handler: thread main exiting due to uncaught exception android.view.WindowManager$NadTokenException: Unable to add window -- token null is not for an application</p> <p>I've looked through the android development site and can't figure it out. I think I'm just missing something obvious but the fix isn't jumping out at me. How can I get this alert dialog to display?</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.

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