Question

I created a TableLayout for my application. Everything is working fine, but once I add the button image at the bottom of the page the alignment breaks. Here is an image before entering the button image code:

After entering the code for the button images:

My xml layout:

</TableLayout>

Answer 1

The layout breaks because the ImageViews that you add at the end stretch the columns where they are placed(for example the second ImageView that you add will stretch the TextView that holds the :). You don’t say how you want them placed but one simple thing that you could do is to wrap them in another layout, like LinearLayout like this:

 <TableRow android:id="@+id/tableRow15" >

        <LinearLayout
            android:layout_span="6"
            android:gravity="center" >

            <ImageView
                android:id="@+id/imbutt1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/ic_launcher" />

            <ImageView
                android:id="@+id/imbutt2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/ic_launcher" />

            <ImageView
                android:id="@+id/imbutt3"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/ic_launcher" />
        </LinearLayout>
    </TableRow>

Of course you could spread them if you want, with the layout_weight attribute.

As a side note, do you really have 6 columns in your layout(you set the layout_span to 6)? Also , do you use those empty singular TextViews or you just use them as dividers(if this is what you want, then you could consider a simple View element outside the TableRows with the desired height)?
