Accepted Answer

Then use your view's object to initialize it:

```
Button mButton = (Button)your_view_object.findViewById(R.id.contact);
mButton.setText("number");
```

When you try to identify a view other than your Activity's layout, you have to pass the reference of that view like this. If not Android will keep looking for this element from the layout which you provided in the `setContentView()`.

For example, consider you have inflated a view like this:

```
View View = mInflater.inflate(R.layout.gridelement, null);
```

Then use this View's object for the Button present in that inflated layout:

```
  Button mButton = (Button)View.findViewById(R.id.contact);
```
