Android获得图片宽高的三种方法

1、// //获取图片真正的宽高,不读入内存

// BitmapFactory.Options options = new BitmapFactory.Options();

// options.inJustDecodeBounds = true;

// Bitmap bitmap = BitmapFactory.decodeFile(path, options);

// options.inSampleSize = 1;

// options.inJustDecodeBounds = false;

//

// int width = options.outWidth;

// int height = options.outHeight;

 

 

第二种

// Glide.with(BottomDialogFragment.this.getContext())

// .load(p.getImgUrl())

// .asBitmap()//强制Glide返回一个Bitmap对象

// .into(new SimpleTarget<Bitmap>() {

// @Override

// public void onResourceReady(Bitmap bitmap, GlideAnimation<? super Bitmap> glideAnimation) {

// int width = bitmap.getWidth();

// int height = bitmap.getHeight();

// Log.e("xudong3","====================");

// Log.e("xudong3",p.getImgUrl());

// Log.e("xudong3", "width " + width); //200px

// Log.e("xudong3", "height " + height); //200px

// }

// });

 

第三种

ExifInterface exifInterface = new ExifInterface(path);

int rotation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

int width = exifInterface.getAttributeInt(ExifInterface.TAG_IMAGE_WIDTH, 0);

int height = exifInterface.getAttributeInt(ExifInterface.TAG_IMAGE_LENGTH, 0);

 

if (rotation == ExifInterface.ORIENTATION_ROTATE_90 || rotation == ExifInterface.ORIENTATION_ROTATE_270) {

 

// 图片被旋转90或者270，使用时候将width、height换下

int temp = height;

height = width;

width = temp;

 

}else {

 

 

// 宽高对应

}
