Question

我知道人们会抱怨以前曾经问过这个问题。我发布它的原因是我看不出我的不同，它不起作用。我花了两天多时间查看其他帖子，但我只是没有看到它。

预期行为：我想启动相机，拍照，然后返回我发起的活动。

实际行为：相机启动并允许我拍照，但之后它只给我重新拍照，取消照片和复选标记的选项。当我按下复选标记时没有任何反应。它没有被冻结，但它不允许我说“是的我拍了照片，还给结果。”

进入我之前活动的唯一方法是按回或取消。如果我按重拍照片，它会返回图片模式并允许我拍摄另一张照片。

导致这种情况的原因是什么？

public void addPhotoEvent(View v) {
        IMAGEID = ((View) ((View) v.getParent()).getParent()).getId();
        holder = ((LinearLayout) ((View) v.getParent()).getParent());
        updated = false;


        Log.v(this.getClass().getSimpleName(), "Photo Event Launch");


        File folder=new File(getFilesDir(),"RedMango");
        File file = new File(folder,"photo"+IMAGEID+".PNG");

        if(!file.exists())
        {
            file.mkdir();
        }
        Uri uri= Uri.fromFile(file);

        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
        startActivityForResult(intent, REQUEST_CODE);
    }
