Android: Can a view (not a viewgroup) contain another view?

Question

I mean something like this

public class ConditionalEditText extends EditText implements TextWatcher
{
    TextView tv;
    ....
}

The TextView is supposed to be displayed only when the EditText satisfies some user specified condition.

I tried to do it like this

public class ConditionalEditText extends LinearLayout implements TextWatcher
{
    EditText edt;
    TextView tv;
    ....
}

but then I cannot specify different XML attributes for edt for different instances of the view in my main layout.

Answer 1

不，只有ViewGroup可以有子视图

Answer 2

Turns out there is a way to do this after all. You can anchor a PopupWindow containing any view(s) you want to another View, which is just what I wanted. I got the code to do so from this link and modified it for my needs.
