推荐答案

您可以通过，而这不会给你图片的确切宽度和高度使用的getWidth（）和getHeight（）得到高度和宽度的ImageView的，对于第一次获得图像的宽度高度，你需要获得绘制背景，然后绘制转换为BitmapDrawable来获得图像从位图，你可以得到的宽度和高度喜欢这里

You can get height and width of ImageView by using getWidth() and getHeight() through while this will not give you the exact width and height of the image, for getting the Image width height first you need to get the drawable as background then convert drawable to BitmapDrawable to get the image as Bitmap from that you can get the width and height like here

Bitmap b = ((BitmapDrawable)imageView.getBackground()).getBitmap();
int w = b.getWidth();
int h = b.getHeight();

或不喜欢这里。

or do like here

imageView.setDrawingCacheEnabled(true);
Bitmap b = imageView.getDrawingCache();
int w = b.getWidth();
int h = b.getHeight();

以上code会给你当前的ImageView大小的位图就像截屏装置的

the above code will give you current imageview sized bitmap like screen shot of device

只有ImageView的大小

for only ImageView size

imageView.getWidth(); 
imageView.getHeight(); 

如果您有绘制的图像，并且希望的大小，你可以得到像这样

If you have drawable image and you want that size you can get like this way

Drawable d = getResources().getDrawable(R.drawable.yourimage);
int h = d.getIntrinsicHeight(); 
int w = d.getIntrinsicWidth();
