Android：拍照，然后立即做作物，无需从画廊中选择

我有完整的工作代码拍照，剪裁，发送带图像附件的电子邮件。Android：拍照，然后立即做作物，无需从画廊中选择

以下是代码流程：拍照>查找并选择我们从图库中删除的图片>裁剪>电子邮件附件。

我想知道如何跳过整个“查找并选择我们刚从图片库中拿出的图片”，拍摄照片后立即直接进入裁剪。

有没有可以做我要求的意图？

我试过这个教程，但它仍然使用户进入画廊寻找他们只是把 http://www.londatiga.net/featured-articles/how-to-select-and-crop-image-on-android/

编辑图片我还要提到的是我有一个自定义视图，当我走图片所以我不知道我是否可以使用意图MediaStore.ACTION_IMAGE_CAPTURE

这是执行裁剪的代码，也让你选择通过查看库中选择的图像。

Intent crop_pic = new Intent(Intent.ACTION_PICK, uriTarget); // used to be ACTION_GET_CONTENT /ACTION_PICK crop_pic.putExtra("crop", "true"); // this enables crop feature //crop_pic.putExtra("aspectX", 200); // this defines the aspect ration //crop_pic.putExtra("aspectY", 150); //crop_pic.putExtra("outputX", 500); // this defines the output bitmap size //crop_pic.putExtra("outputY", 500); //crop_pic.putExtra("scale", true); try { crop_pic.putExtra("return-data", false); // true to return a Bitmap, false to directly save the cropped iamge crop_pic.putExtra(MediaStore.EXTRA_OUTPUT, uriTarget); // save output image in uri //crop_pic.setDataAndType(uriTarget, "image/*"); // this will open all images in the Galery startActivityForResult(crop_pic, EMAIL_PIC); overridePendingTransition(R.anim.fadein, R.anim.fadeout); } catch (ActivityNotFoundException e) { toast.showToastDialog(getApplicationContext(), e.toString()); } LOGCAT.DEBUG(TAG, "Cropping Picture"); }

有没有一个意图im没有意识到，只要开始裁剪，如果我提供一个uri目标？

下面是完整的代码：

任何想法，家伙？ –

您有'myPictureCallback.onPictureTaken（）'它可以处理** byte [] arg0 **中的Jpeg流。没有'MediaStore。ACTION_IMAGE_CAPTURE'的意图，据我所知，因此[@whizzle]（http://stackoverflow.com/users/1687169/whizzle）的解决方案是不适用的。 –

谢谢你的宝贵意见亚历克斯！你对我应该如何处理这个问题有任何意见吗？ –
