If you get -1 or -2 it could also be the numeric value of LayoutParams WRAP CONTENT  -2  or LayoutParams MATCH PARENT  -1

I had same issue but didn t want to draw on screen before measuring so I used this method of measuring the view before trying to get the height and width   Example of use   layoutView view   int height   view getHeight            void layoutView View view        view setDrawingCacheEnabled true       int wrapContentSpec            MeasureSpec makeMeasureSpec MeasureSpec UNSPECIFIED  MeasureSpec UNSPECIFIED       view measure wrapContentSpec  wrapContentSpec       view layout 0  0  view getMeasuredWidth    view getMeasuredHeight

I used DisplayMetrics to get the screen size and then i can assign the width height to an element in  age  It will be like this  DisplayMetrics dmetrics   new DisplayMetrics    int widthPixels dmetrics widthPixels  int heightPixels dmetrics heightPixels            setting the height of the button  button nextPuzzle setMinHeight  int    heightPixels 3   30      Worked for me very well

you can use coroutines as well  like this one    CoroutineScope Dispatchers Main  launch           delay 10          val width   view width           val height  view height              do your job

The view itself  has it s own life cycle which is basically as follows    Attached Measured Layout Draw   So  depending on when are you trying to get the width height you might not see what you expect to see  for example  if you are doing it during onCreate  the view might not even been measured by that time  on the other hand if you do so during onClick method of a button  chances are that by far that view has been attached  measured  layout  and drawn  so  you will see the expected value  you should implement a ViewTreeObserver to make sure you are getting the values at the proper moment   LinearLayout layout    LinearLayout findViewById R id YOUD VIEW ID   ViewTreeObserver vto   layout getViewTreeObserver     vto addOnGlobalLayoutListener new OnGlobalLayoutListener           Override      public void onGlobalLayout              if  Build VERSION SDK INT  lt  Build VERSION CODES JELLY BEAN                    this layout getViewTreeObserver   removeGlobalOnLayoutListener this                 else                   this layout getViewTreeObserver   removeOnGlobalLayoutListener this                          int width    layout getMeasuredWidth            int height   layout getMeasuredHeight

As I just ran into this problem thought I would write it for kotlin   my view viewTreeObserver addOnGlobalLayoutListener             here your view is measured           get height using my view height           get width using my view width         or  my view post             here your view is measured           get height using my view height           get width using my view width

just give your height and You will get height or even width if wanted              Get the view height before the view will render         param view the view to measure         return the height of the view          public static int getViewHeight View view        WindowManager wm                WindowManager  view getContext   getSystemService Context WINDOW SERVICE       Display display   wm getDefaultDisplay         int deviceWidth       if android os Build VERSION SDK INT  gt   Build VERSION CODES HONEYCOMB MR2           Point size   new Point            display getSize size           deviceWidth   size x        else           deviceWidth   display getWidth               int widthMeasureSpec   View MeasureSpec makeMeasureSpec deviceWidth  View MeasureSpec AT MOST       int heightMeasureSpec   View MeasureSpec makeMeasureSpec 0  View MeasureSpec UNSPECIFIED       view measure widthMeasureSpec  heightMeasureSpec       return view getMeasuredHeight              view getMeasuredWidth

try something like this code from this link  ViewTreeObserver viewTreeObserver   view getViewTreeObserver    if  viewTreeObserver isAlive       viewTreeObserver addOnGlobalLayoutListener new OnGlobalLayoutListener      Override public void onGlobalLayout       view getViewTreeObserver   removeGlobalOnLayoutListener this     viewWidth   view getWidth      viewHeight   view getHeight               hope this helps

As CapDroid say  you are trying to get the size before the view drawn  another possible solution could be to do a Post with a runnable on the View       mView post new Runnable              Override         public void run                 int width   mView getWidth                int height   mView getHeight

I think you are getting Height and Width in OnCreate    method that s why you getting always 0 values because at that time your view still not created   Try to get height and width on some button click or else

Most easiest way is to use ViewTreeObserver  if you directly use  height or  width you get values as 0  due to views are not have size until they draw on our screen  Following example will show how to use ViewTreeObserver  ViewTreeObserver viewTreeObserver   YOUR VIEW TO MEASURE getViewTreeObserver            if  viewTreeObserver isAlive                  viewTreeObserver addOnGlobalLayoutListener new ViewTreeObserver OnGlobalLayoutListener                      Override                 public void onGlobalLayout                          YOUR VIEW TO MEASURE getViewTreeObserver   removeOnGlobalLayoutListener this                       int viewHeight   YOUR VIEW TO MEASURE getHeight                        int viewWeight   YOUR VIEW TO MEASURE getWidth                                                   if you need to use this on method  use like this and to save the values you can use globle variables

Just wanted to add an answer here  since Koltin has some convenience methods to do this  which are a lot less ugly than adding and removing a onGlobalLayoutListener   view doOnLayout       it measuredWidth     it measuredHeight     You can see more of the convinience methods here

try with this metods   int width   mView getMeasuredWidth     int height   mView getMeasuredHeight      Or  int width   mTextView getMeasuredWidth     int height   mTextView getMeasuredHeight

User · Answer

The first snippet is correct  but you need to call it after onMeasure   gets executed  Otherwise the size is not yet measured for the view
