Question: I am being passed inconsistent data. The problem is the individual rows of `$data_array` are not consistently in the same sequence but each has a reliable "text:" preceding the value. 

Each row contains about 120 elements of data. I only need 24 of those elements.

It's also possible one of the elements I need could be missing, such as "cost".

(I'm using php version 5.4)  

-- Task: 

Using $order\_array, create a new $data\_array\_new by reordering the data in each "row" into the same sequence as $order\_array.

If an elements is missing from a row insert "NA".

Once the elements are in the correct sequence the "text" is no longer required.

```
$order_array = array("price", "cost", "vol", "eps")
$data_array = Array (
    $one = Array ("cost":43.40, "vol":44000,   "eps":1.27,   "price":65.00),
    $two = Array ("eps":5.14,   "price":33.14, "vol":657000),
    $thr = Array ("vol":650000, "cost":66.67,  "eps":1.33,   "price":44.31),
);

```

The resulting ouput should appear with the data in this order: ("price", "cost", "vol", "eps")

```
$data_array_new = Array (
    $one = Array (65.00,43.40,44000,1.27),
    $two = Array (33.14,"NA",657000,5.14),
    $thr = Array (44.31,66.67,650000,1.33),
);

```

Answer: 
Yes you can, but you have to add more logic to your fragments and add some interfaces for each activity.
I don't recommend to do that, maybe you could reuse your layouts.
Your activities have different logic, you can define the button logic in each of them and share the views in this way. You can use a fragment to accomplish this however you can be more direct by sharing a partial layout.

Create a partial layout called three\_buttons.xml

three\_buttons.xml

```
<LinearLayout>
<BUtton android:text="button 1"/>
<BUtton android:text="button 2"/>
<BUtton android:text="button 3"/>
</LinearLayout>

```

activity\_a.xml 

```
<LinearLayout>
<TextView android:text="I am A"/>
<include
            android:id="@+id/three_buttons"
            layout="@layout/three_buttons"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
</LinearLayout>

```

activity\_b.xml 

```
<LinearLayout>
<TextView android:text="I am B"/>
<include
            android:id="@+id/three_buttons"
            layout="@layout/three_buttons"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
</LinearLayout>

```
