    <p>I am using a custom title view and would like to show/hide a progressbar in the title view when a thread is working.</p> <p>This is my title view's XML</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" &gt; &lt;Button android:id="@+id/image_left_btn" android:layout_width="75dip" android:layout_height="wrap_content" android:text="Back" /&gt; &lt;TextView android:id="@+id/image_title_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:textSize="20dip" android:textStyle="bold" android:textColor="#fff" android:layout_gravity="center" android:gravity="center" android:paddingLeft="8dip" android:paddingRight="8dip" /&gt; &lt;ProgressBar android:id="@+android:id/progress_small_title" style="?android:attr/progressBarStyleSmall" android:layout_width="75dip" android:layout_height="wrap_content" android:paddingRight="8dip"/&gt; &lt;/LinearLayout&gt; </code></pre> <p>In my Activity, after setting this as the custom title bar, I do this</p> <pre><code>titleProgress = (ProgressBar)findViewById(R.id.progress_small_title); titleProgress.setVisibility(View.INVISIBLE); </code></pre> <p>where titleProgress is ProgressBar object.</p> <p>This is what I do in my thread</p> <pre><code>runOnUiThread(new Runnable() { public void run() { titleProgress.setVisibility(View.VISIBLE); } }); //long operation here runOnUiThread(new Runnable() { public void run() { titleProgress.setVisibility(View.INVISIBLE); } }); </code></pre> <p>But there is no change to the progress bar. It is never displayed. Can someone please tell me what is wrong with the code?</p> <p>Is it possible to display the title progressbar in a custom title?</p> <p>Thanks.</p>

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.
