Custom Dialog Boxes to show image, text and setTit

Question

I have a little glitch in my program I've been trying to figure out what it is I'm missing. In my .java file, I have a gridview of images where I setOnItemsClickListener on items in the gridview. I have 2 xml files, one for the .java and the other is set as contentview to popup window on click on any of the gridview items. I want it that whenever user clicks on item in gridview, the custom dialog box pops up, to show the image clicked, plus a brief description on the image.

So far, the dialog pops out quite alright, but no details are passed unto this dialog box.

THis is my activity_first.xml code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/background"
    >

<GridView
    android:id="@+id/gridView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:numColumns="3" 
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:columnWidth="90dp"
    android:gravity="center" >

</GridView>

</LinearLayout>

This is my activity_custom_dialog.xml file

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/background">
    <TableLayout    
        android:id="@+id/tableLayout1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <!-- 2 columns -->
        <TableRow
            android:id="@+id/tableRow1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="5dip" >

            <ImageView
                android:id="@+id/imageView1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginRight="5dp" />
            <TextView
                android:id="@+id/textView1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textAppearance="?android:attr/textAppearanceLarge" />

        </TableRow>

        <!-- Button span 2 column -->
        <TableRow
            android:id="@+id/tableRow2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="5dip" >

    <Button
                android:id="@+id/button1"
                android:text="Ok" />
        </TableRow>
    </TableLayout>

</LinearLayout>

Finally, this is how my Image.Java file looks like:

I'd really appreciate it should I get a guide asap on how to get around this lil glitch my lil programmer eyes cannot see. :-)

Thanks in advance.
