在fragement获取view宽高

在onCreateView（）里调用

ViewTreeObserverobserver=imageViewPicture.getViewTreeObserver();observer.addOnGlobalLayoutListener(newOnGlobalLayoutListener(){@OverridepublicvoidonGlobalLayout(){imageViewPicture.getViewTreeObserver().removeGlobalOnLayoutListener(this);}});

而不是

finalViewTreeObserverobserver=imageViewPicture.getViewTreeObserver();observer.addOnGlobalLayoutListener(newOnGlobalLayoutListener(){@OverridepublicvoidonGlobalLayout(){observer.removeGlobalOnLayoutListener(this);}});

后者有可能会出现问题
