Demo中根据Uri去获取拍照的图片路径报错

vivian688 commented 7 years ago

从图库选择的没问题，但是拍照返回的Uri再调用PhotoMetadataUtils.getPath()获取路径报错。cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA)总返回-1。

jklwan commented 7 years ago

自己拍照的图片需要通知系统进行对该图片进行信息收集，否则数据库是没有数据的。例如sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(file));); 当然还有其他方式

vivian688 commented 7 years ago

建议添加获取绝对路径的方法。

拍照返回的uri，我根本显示不了啊，怎么解决的

jaysonShao commented 7 years ago

花了，半天时间找到的 http://www.jianshu.com/p/f9a63fcc0b91

fuyoutianxia commented 7 years ago

我选择图片返回的uri是正常的： content://media/external/images/media/190403 但是拍照之后返回的uri是这种格式的： content://com.example.yangqi.zhihuphoto.fileprovider/my_images/PicturesJPEG_20170712091444.jpg 以.jpg结尾的

jaysonShao commented 7 years ago

/storage/emulated/0/DCIM/Camera/IMG_20170625_154426R.jpg 这种格式才是可以给 file的。 content://media/external/images/media/198609 这种事 file 无法获取的格式。

大家复制粘贴就可以

fuyoutianxia commented 7 years ago

感谢你回答的这么详细，我选择的图片能够转成路径： /storage/emulated/0/DCIM/Camera/20170629_135631.jpg 但是拍照之后获取的uri是 content://com.example.yangqi.zhihuphoto.fileprovider/my_images/PicturesJPEG_20170712155600.jpg 按照你的方法也无法转换成路径，还有拍照的照片是存在根目录的，如何改变存储路径呢

拍照之后返回的uri是这种格式的： content://com.example.yangqi.zhihuphoto.fileprovider/my_images/PicturesJPEG_20170712091444.jpg 以.jpg结尾上面方法按照上面的方法还是ursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA)总返回-1。

            Cursor cursor = App.getAppContext().getContentResolver().query(uri, new String[]{MediaStore.Images.ImageColumns.DATA}, null, null, null);
            if (null != cursor) {
                if (cursor.moveToFirst()) {
                    int index = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
                    if (index > -1) {

        if (data == null) {
            data = uri2path(uri);
        }
        return data;
    }

通过getRealFilePath()方法去获取uri ，然后cursor数据获取空的时候另外拼接处理，此方法是我自己暴力写的，暂时还没发现其他手机有bug。如果出现问题可以艾特我。

忘了说一点，CaptureStrategy 要设置为true. 开放的。

@qdxxxx 相册照片可获取，但是照相机的无法获取，小米3

vihuela commented 7 years ago

可以这样了，拍照的uri有回调，fileProvider的主机名，可以这样判断，拍照相册都没有问题 https://gist.github.com/vihuela/ee973db7b43e085a1c197a4621847b65

xuwiller commented 6 years ago

针对这个问题，特意的去翻了下源码，发现拍照生成的图片文件是固定的，所以我们可以根据uri 自己拼凑出路径直接上代码。当你通过其他方法拿不到路径时可以这样 if (TextUtils.isEmpty(realFilePath)) { if(uri != null) { String uriString = uri.toString(); int index = uriString.lastIndexOf("/"); String imageName = uriString.substring(index); File storageDir;

                storageDir = Environment.getExternalStoragePublicDirectory(
                            Environment.DIRECTORY_PICTURES);
                File file = new File(storageDir, imageName);
                if(file.exists()) {
                    realFilePath = file.getAbsolutePath();
                } else {
                    storageDir = mContext.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
                    File file1 = new File(storageDir, imageName);
                    realFilePath = file1.getAbsolutePath();
                }
                //
            }
        }
