在onCreate初中获取View中的宽、高

int finalHeight, finalWidth; final ImageView iv = (ImageView)findViewById(R.id.scaled_image); final TextView tv = (TextView)findViewById(R.id.size_label); ViewTreeObserver vto = iv.getViewTreeObserver(); vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() { public boolean onPreDraw() { finalHeight = iv.getMeasuredHeight(); finalWidth = iv.getMeasuredWidth(); tv.setText("Height: " + finalHeight + " Width: " + finalWidth); return true; } });

在群里获取的。不知道对不对。。没测试过
