get parent's view from a layout

Question

I have a FragmentActivity with this layout:

Answer 1

If you are trying to find a View from your Fragment then try doing it like this:

int w = ((EditText)getActivity().findViewById(R.id.editText1)).getLayoutParams().width;

Answer 2

The RelativeLayout (i.e. the ViewParent) should have a resource Id defined in the layout file (for example, android:id=@+id/myParentViewId). If you don't do that, the call to getId will return null. Look at this answer for more info.

Answer 3

The use of Layout Inspector tool can be very convenient when you have a complex view or you are using a third party library where you can't add an id to a view

Answer 4

This also works:

this.getCurrentFocus()

It gets the view so I can use it.

Answer 5

Just write

this.getRootView();

Answer 6

You can get ANY view by using the code below

view.rootView.findViewById(R.id.*name_of_the_view*)

EDIT: This works on Kotlin. In Java, you may need to do something like this=

this.getCurrentFocus().getRootView().findViewById(R.id.*name_of_the_view*);

I learned getCurrentFocus() function from: @JFreeman 's answer
