getmeasuredheight() and getmeasuredwidth() returns 0 after View.measure()

Question

After measuring a View with a constant dimensions with view.measure(), the getMeasuredHeight() and getMeasureWidth() is returning 0.

layout_view.xml, layout which is inflated to create the view

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="100dp"
    android:layout_height="100dp">
</FrameLayout>

function which measures the dimensions

public void measureView(Context context){
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.layout_view,null,false);

    view.measure( View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);

    Log.d(TAG,"Error width : " + view.getMeasuredWidth());
    Log.d(TAG,"Error height : " + view.getMeasuredHeight());

}

@GiruBhai i tried using ViewTreeObserver, its also not working — SathMK, Jun 26 '14 at 12:30
`View.MeasureSpec.*` can't be used directly, check my answer below. — M-Wajeeh, Jul 09 '15 at 12:47

When you call view.getMeasuredWidth() in onCreate() or onCreateView(), the view has not been drawn yet. So you need to add a listener and will get a callback when the view is being drawn. Just like this in my code:

final ViewTreeObserver vto = view.getViewTreeObserver();
if (vto.isAlive()) {
    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            int viewWidth = view.getMeasuredWidth();
            // handle viewWidth here...

            if (Build.VERSION.SDK_INT < 16) {
                vto.removeGlobalOnLayoutListener(this);
            } else {
                vto.removeOnGlobalLayoutListener(this);
            }
        }
    });
}

NOTE: Remove the listener for better performance!

Don't call vto.removeOnGlobalLayoutListener(this) to remove the listener. Call it like this:

vto.getViewTreeObserver()

I tried this and it seemed to work in all tested cases but now I see the getMeasuredWidth() returning 0 in production for some users :( – Sebas LG Sep 12 '16 at 09:33
Thank you! I was using ```OnPreDrawListener``` before (but seems it is not compatible with some devices 4.4.4 and 6.0.1). Using ```onGlobalLayout``` and removing the listener just when ```height > 0``` it works perfectly. – JCarlosR Nov 16 '16 at 22:18

What is `v`? It came out of nowhere. – Damn Vegetables Mar 06 '18 at 14:45
For some reason `getMeasuredWidth`only returns the "right" value after scrolling take place. Is there another way to trigger a correct measurement? – rraallvv Apr 04 '18 at 11:42

Are you measuring the view in onCreate(). The view isn't drawn yet. You have to wait until a time after the view is drawn before you can measure it.

Simple solution for this is to post a runnable to the layout. The runnable will be executed after the layout has happened.

For more info See this post

Edit try to change

view.measure( View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);

to

view.measure( View.MeasureSpec.EXACTLY, View.MeasureSpec.EXACTLY);

i am measuring the the view in in onclick method. To avoid the issue you pointed out i am explicitly measuring the view with `view.measure()` – SathMK Jun 26 '14 at 12:39
i tried this may also, but still the result is zero – SathMK Jun 26 '14 at 13:16

Try this way,hope this will help you to solve your problem.

view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
   @Override
   public void onGlobalLayout() {
     int width = view.getMeasuredWidth();
     int height = view.getMeasuredHeight();

   }
});

if your measured view has visibility set to gone, measuring will return 0. You can set it to visible, measure, and then set back to gone, all from code.

You can not use View.MeasureSpec.* directly in measure call. Instead first makeMeasureSpec() and then use it to invoke measure():

final int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(ViewGroup.LayoutParams.WRAP_CONTENT/*can be match_parent or some exact value*/, View.MeasureSpec.UNSPECIFIED);
final int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(ViewGroup.LayoutParams.WRAP_CONTENT/*can be match_parent or some exact value*/, View.MeasureSpec.UNSPECIFIED);
view.measure(widthMeasureSpec, heightMeasureSpec);

Thanks, but currently Kotling restricts passing this value (WRAP_CONTENT = -2 < 0). In my case https://stackoverflow.com/a/53739033/2914140 helped in `onCreateView()`, simply called view.measure(0, 0). In other events you should use `getViewTreeObserver()`, see https://stackoverflow.com/questions/14592930/getwidth-returns-0-if-set-by-androidlayout-width-match-parent. – CoolMind May 28 '19 at 11:50
```View.MeasureSpec.makeMeasureSpec(ViewGroup.LayoutParams.WRAP_CONTENT, View.MeasureSpec.UNSPECIFIED);```not work, it says ```Value must be ≥ 0 (was -2)``` – DawnYu May 25 '21 at 01:42

Just in case someone was experiencing this problem with ImageView:

I noticed that if your ImageView doesn't have "android:src" set (i.e. you change it dynamically) it will always return zero from getMeasuredWidth/Height.

A simple workaround would be to set a placeholder for view.

getHeight/getMeasuredHeight still gives 0, after setting placeholder – Zulqurnain Jutt Apr 16 '19 at 11:24

You can use getViewTreeObserver in onCreate/onCreateView and other events.

fun setGlobalLayoutListener(view: View, method: () -> Unit) {
    val vto1 = view.viewTreeObserver
    if (vto1.isAlive) {
        vto1.addOnGlobalLayoutListener(object : ViewTreeObserver.OnGlobalLayoutListener {
            override fun onGlobalLayout() {
                val vto2 = view.viewTreeObserver
                if (vto2.isAlive) {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                        vto2.removeOnGlobalLayoutListener(this)
                    } else {
                        @Suppress("DEPRECATION")
                        vto2.removeGlobalOnLayoutListener(this)
                    }
                    // Your actions are here:
                    method()
                }
            }
        })
    }
}

And call it: setGlobalLayoutListener(view) {updateUI(view)}.

I also tried

view.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED)

and then called view.control.measuredWidth in onCreateView()/onViewCreated(). But in some emulators (API 19) it returned wrong results.

getmeasuredheight() and getmeasuredwidth() returns 0 after View.measure()
