Android的 - ImageView的显示图像从画廊＆QUOT;景观＆QUOT; [英] Android - ImageView showing image from Gallery in "landscape"

问题描述

首先，在所有的，也许风景是不是更好的词来形容，但我想不出另外一个在当下。

First at all, maybe "landscape" isn't the better word to describe, but i can't think another one in the moment.

我用下面的code，显示在ImageView的图像，但我认为在纵向采取与设备的图像（头抬起）是显示瞟。

I'm using the following code to show an image in an ImageView, but my image that was taken with the device in "portrait" (head up) is showing sidelong.

我的code：

mImageView  = (ImageView) findViewById(R.id.iv_photo);

Uri u = Uri.parse("content://media/external/images/media/7");
mImageView.setImageURI(u);

XML：

<ImageView
    android:id="@+id/iv_photo"
    android:layout_width="wrap_content"          
    android:layout_height="wrap_content"/>

是的，内容：//媒体/外部/图像/媒体/ 7是一个有效的路径。

And yes, "content://media/external/images/media/7" is a valid path.

任何想法？

推荐答案

只需查看图像的尺寸，如果它长得比它更宽，那么你可以旋转：结果

Just check the image's dimensions, if it's taller than it is wider, then you can rotate it:

相关位是：

  bitmap = BitmapFactory.decodeFile(imageInSD);
  bmpWidth = bitmap.getWidth();
  bmpHeight = bitmap.getHeight();

  Matrix matrix = new Matrix();
  matrix.postScale(curScale, curScale);
  matrix.postRotate(curRotate);

  Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bmpWidth, bmpHeight, matrix, true);
  myImageView.setImageBitmap(resizedBitmap);
