拍照后在onActivityResult中获取图像Uri？

发布于 2024-10-18 10:32:28 字数 265 浏览 1 评论 0原文

我有这个代码：

startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE), CAMERA_IMAGE);

允许该用户拍照。现在我如何在 onActivityResult 中获取该照片的 Uri ？这是一个额外的Intent吗？是通过Intent.getData()吗？

I have this code:

startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE), CAMERA_IMAGE);

That allows that user to take a photo. Now how would I get the Uri of that photo in onActivityResult? Is it an Intent extra? Is it through Intent.getData()?

protected void onActivityResult(int requestCode, int resultCode, Intent intent){
    Uri u = intent.getData();
}

顺便说一句......在某些设备中存在一个与此意图相关的错误。查看此答案了解如何解决该问题。

protected void onActivityResult(int requestCode, int resultCode, Intent intent){
    Uri u = intent.getData();
}

By the way... there's a bug with that intent in some devices. Take a look at this answer to know how to workaround it.

不要只是启动意图，还要确保告诉意图您想要照片的位置。

Uri uri = Uri.parse("file://somewhere_that_you_choose");
Intent photoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
photoIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(photoIntent, CAMERA_IMAGE);

然后，当您调用 onActivityResult() 方法时，如果成功，只需打开一个到 URI 的流，并且应该全部设置完毕。

Instead of just launching the intent, also make sure to tell the intent where you want the photo.

Uri uri = Uri.parse("file://somewhere_that_you_choose");
Intent photoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
photoIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(photoIntent, CAMERA_IMAGE);

Then when you get your onActivityResult() method called, if it was a success just open a stream to the URI and it should all be set.

Uri uri = null;
if(requestCode == GALLERY_INTENT && resultCode == RESULT_OK){
  uri = data.getData();
}

Uri uri = null;
if(requestCode == GALLERY_INTENT && resultCode == RESULT_OK){
  uri = data.getData();
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {

          Bitmap photo = (Bitmap) data.getExtras().get("data");
          Uri fileUri = Utils.getUri(getActivity(), photo);
    }  
}

    String path = null;

    Cursor cursor = getActivity().getContentResolver().query(contentUri, proj, null, null, null);
    if (cursor.moveToFirst()) {
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
        path = cursor.getString(column_index);
    }
    cursor.close();
