Android get layout height and width in a fragment


There's a cleaner solution to this, just use the View.post() method on your fragment's root view, and you can call getMeasuredHeight()/getMeasuredWidth() and get the actual values.

E.g.

public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {    View root = inflater.inflate(R.layout.myfragment, container, false);    root.post(new Runnable() {        @Override        public void run() {            // for instance            int height = root.getMeasuredHeight();         }    });    return root;}

Very neat and tidy and no messy mucking about with the ViewTreeObserver.

I've only tested this with android-23 devices, but the API has had this method since level 1.

Anyway, WFM.


The addOnGlobalLayoutListener will be called whenever small change of the view happened. So you need to remove this listener from the view.

Simple usage:

public static void removeOnGlobalLayoutListener(View v, ViewTreeObserver.OnGlobalLayoutListener listener){if (Build.VERSION.SDK_INT < 16) {    v.getViewTreeObserver().removeGlobalOnLayoutListener(listener);} else {    v.getViewTreeObserver().removeOnGlobalLayoutListener(listener);}

}

I would suggest you to check :

if (myLayout.getHeight()>0 && myLayout.getWidth()>0) {// Do some code...removeOnGlobalLayoutListener(..)}


In onActivityCreated, the view hasn't been measured yet.

So no, you can't get the measurements from there. onGlobalLayout is a good place to do it. Layouts happen directly after measurement.

You can remove your listener afterwards, if you only want to do it once. Note that layouts can change size though (soft keyboards appearing, for example)
