我想裁剪图像，但我希望能够将裁剪区域设置为完全640px x 640px。我想prevent从裁剪到一个非常小的区域中的用户。所以基本上我会preFER有对种植面积固定的高度和宽度。我已经看过成几个第三方库，但没有看到解决这个问题。我怎样才能做到这一点？

I am trying to crop an image but I want to be able to set the cropped area to exactly 640px x 640px. I want to prevent a user from cropping down to a really small area. So basically I would prefer to have a fixed height and width for the cropping area. I have looked into several third party libraries but don't see solving this problem. How can I do this?

推荐答案

我会使用这些解决方案之一：

I'd use one of these solutions:

https://github.com/jdamcd/android-crop https://github.com/edmodo/cropper https://github.com/jdamcd/android-crop https://github.com/edmodo/cropper

这两个似乎是适当的为您解决问题和确保覆盖更多优势的情况下，设备和其他Android的东西只是为了更加稳定可靠。

Both seems to be appropriate to solve your problem and for sure cover more edge cases, devices and other Android stuff just to be more stable and reliable.

编辑： 我已经介绍了一些更改，以 Android的作物，现在你可以使用 withFixedSize（INT宽度，诠释高）来以像素为单位设置固定种植面积。 看起来是这样的：

I have introduced a few changes to android-crop and now you can use withFixedSize(int width, int height) to set fixed cropping area in pixels. Looks like this:

 private void beginCrop(Uri source) {
        Uri outputUri = Uri.fromFile(new File(getCacheDir(), "cropped"));
        new Crop(source).output(outputUri).withFixedSize(640, 640).start(this);
    }
