拍照、相册及裁剪的终极实现（一）——拍照及裁剪功能实现- http://blog.csdn.net/harvic880925/article/details/43163175
看似简单的问题，在各个厂商手机上有不同的问题，请广而测之，
> 方案如下：将中间数据先暂存一下，然后再调裁剪Intent，最后把结果存在Uri中。

//裁剪图

// 裁剪图片意图

intent.setDataAndType(uri, "image/*");
intent.putExtra("crop", "true");
// 裁剪框的比例，1：1

// 裁剪后输出图片的尺寸大小
intent.putExtra("outputX", 250);
intent.putExtra("outputY", 250);
// 图片格式
intent.putExtra("outputFormat", "JPEG");
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
intent.putExtra("noFaceDetection", true);// 取消人脸识别
