Here is my code.....

```
<ImageView
    android:id="@+id/ImageShow"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" /> 

 <EditText
android:id="@+id/postal_address"

```

Answer: 
by using data-target you can achieve this as

```
<a data-toggle="collapse" data-target="#id_to_expand">click</a>

```

hope this will help you
you have set panel-group id=accordion twice. Thats not good.
Wrap your two panels into one panel-group-block with one id:

```
   <div class="panel-group" id="accordion">
    <div class="panel panel-default">
        <div class="panel-heading">
            <h3 class="panel-title">
                <a class="accordion-toggle collapsed" data-parent="#accordion" href="#collapseOne" data-toggle="collapse">Heading 1</a>
            </h3>
        </div>
        <div class="panel-collapse collapse" id="collapseOne">
            <div class="panel-body">
                <p><a href="#SubTitle2">Test</a></p>
            </div>
        </div>
    </div>
    <!-- SNIP
    </div>
    <div class="panel-group" id="accordion">
    SNAP -->
    <div class="panel panel-default">
        <div class="panel-heading">
            <h3 class="panel-title">
                <a class="accordion-toggle collapsed" data-parent="#accordion" href="#collapseTwo" data-toggle="collapse">Heading 2</a>
            </h3>
        </div>
        <div class="panel-collapse collapse" id="collapseTwo">
            <div class="panel-body">
                <p id="SubTitle2">Content</p>
            </div>
        </div>
    </div>
    </div>

```
