android-如何从uri获取视频文件路径

概述我正在尝试从视频uri获取文件路径.我浏览了以下链接,但仍然遇到此问题：get-filename-and-path-from-uri-from-mediastoreget-file-path-from-uri-from-video-chooser以下是我的代码：UriimageUri=data.getData();String[]proj={MediaStore.Audio.Media.

我正在尝试从视频uri获取文件路径.

我浏览了以下链接,但仍然遇到此问题：

get-filename-and-path-from-uri-from-mediastore

get-file-path-from-uri-from-video-chooser

以下是我的代码：

        Uri imageUri = data.getData();        String[] proj = { MediaStore.Audio.Media.DATA };        Cursor cursor = PreferenceHelper.getContext().getContentResolver().query(imageUri, proj, null, null, null);        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);        cursor.movetoFirst();        String filePath = cursor.getString(column_index);        sendVIDeo(activity, filePath, windowID, isChatroom);

内容：//com.androID.provIDers.media.documents/document/vIDeo：1142

但始终将文件路径获取为空.

以下是我的日志：

解决方法:

您好我也遇到了同样的问题,但这是方法

 public static String getPath(final Context context, final Uri uri) {    if (DEBUG)        Log.d(TAG + " file -",                "Authority: " + uri.getAuthority() +                        ", Fragment: " + uri.getFragment() +                        ", Port: " + uri.getPort() +                        ", query: " + uri.getquery() +                        ", Scheme: " + uri.getScheme() +                        ", Host: " + uri.getHost() +                        ", Segments: " + uri.getPathSegments().toString()                );    final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;    // documentProvIDer    if (isKitKat && documentsContract.isdocumentUri(context, uri)) {        // ExternalStorageProvIDer        else if (isExternalStoragedocument(uri)) {            final String docID = documentsContract.getdocumentID(uri);            final String[] split = docID.split(":");            final String type = split[0];            if ("primary".equalsIgnoreCase(type)) {                return Environment.getExternalStorageDirectory() + "/" + split[1];            }            // Todo handle non-primary volumes        }        // MediaProvIDer        else if (isMediadocument(uri)) {            final String docID = documentsContract.getdocumentID(uri);            final String[] split = docID.split(":");            final String type = split[0];            Uri contentUri = null;            if ("image".equals(type)) {                contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;            } else if ("vIDeo".equals(type)) {                contentUri = MediaStore.VIDeo.Media.EXTERNAL_CONTENT_URI;            } else if ("audio".equals(type)) {                contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;            }            final String selection = "_ID=?";            final String[] selectionArgs = new String[] {                    split[1]            };            return getDataColumn(context, contentUri, selection, selectionArgs);        }    }    // MediaStore (and general)    else if ("content".equalsIgnoreCase(uri.getScheme())) {        // Return the remote address        if (isGooglePhotosUri(uri))            return uri.getLastPathSegment();        return getDataColumn(context, uri, null, null);    }    // file    else if ("file".equalsIgnoreCase(uri.getScheme())) {        return uri.getPath();    }    return null;}

我从this url得到

->可以从此file UTILS文件中获取其他方法,进行编码：)
->从uri那里获得了我完整的视频路径,希望对您有所帮助:)
