【中文标题】获取 Uri Android 的真实路径【英文标题】：Get Real Path For Uri Android 【发布时间】：2013-07-06 22:25:23 【问题描述】：我正在开发VideoPlayer。我将启动意图的URI 转换为字符串，它给了我content://media/external.....。但我需要找到真正的路径。
例如： /storage/extSdcard....。
我该怎么做？
如果需要，这是我的代码：
videoURI = getIntent().getData();
vv.setVideoURI(videoURI);
videoName = videoURI.toString();
tvTitle.setText(videoName);
【问题讨论】：
【参考方案1】：使用此代码。这适用于所有 android 版本。这是经过测试的代码。这支持所有设备

【讨论】：
当DocumentsContract 本身仅在 API 级别 19 KitKat 之后可用时，这如何在所有 Android 版本上运行？ developer.android.com/reference/android/provider/…
应该已经提到了原答案：***.com/a/27271131/1567541
@SANJAYGUPTA getPathFromUri() 将为外部 sdcard 文件返回 null。有什么解决方案吗？？
如果存储是存储卡会怎样？如果在 Android L 中使用此方法，非主 get 为 null
它不能在 android 7 上运行。停止并出现此错误：列 '_data' 不存在【参考方案2】：
您可以将此代码用于选定的视频路径。
Uri uri = data.getData();
String[] filePathColumn = MediaStore.Images.Media.DATA;
Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
if(cursor.moveToFirst())
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String yourRealPath = cursor.getString(columnIndex);
else
//boooo, cursor doesn't have rows ...
cursor.close();

在您的活动或片段中获取绕过 URI 到 getRealPathFromURI 函数的真实路径：
val fileRealPath = getRealPathFromURI(context!!, fileURI) ?: ""
【讨论】：
你好，在我的例子中，它进入 isDownloadDocument 路径，但 _id 是 msf:24，而不是 raw: & 不是数字。你能帮忙吗？ @SanskarDahiya 如果id.startsWith("msf:") ***.com/a/62154537/2462531 试试这个方法
您好，我已经检查过了，但是内存有问题。因此，从 Andorid 文档中创建一些解决方案： if (isAndroid10 && id.startsWith("msf:")) final String[] split = id.split(":");最终字符串选择 = "_id=?"; final String[] selectionArgs = new String[] split[1] ;返回 getDataColumn(context, MediaStore.Downloads.EXTERNAL_CONTENT_URI, selection, selectionArgs); 【参考方案4】：
这是我以前用过的东西：
public String getRealPathFromURI (Uri contentUri)
String path = null;
String[] proj = MediaStore.MediaColumns.DATA ;
Cursor cursor = 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();
return path;
【讨论】：
光标为空。 这适用于媒体内容（来自媒体内容提供商），但不适用于存储访问框架文件。 @PriyankaSingh 你已经接受了一个答案。如果您已经走得更远了，现在遇到了稍微不同的问题，请发布一个新的具体问题 @KenWolf 接受的答案不适用于所有版本。【参考方案5】：大多数答案不适用于图库和相机图像。这对我有用。
public static String getPath(final Context context, final Uri uri)
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
Log.i("URI",uri+"");
String result = uri+"";
// DocumentProvider
// if (isKitKat && DocumentsContract.isDocumentUri(context, uri))
if (isKitKat && (result.contains("media.documents")))

int length = ary.length;
String imgary = ary[length-1];
final String[] dat = imgary.split("%3A");
final String docId = dat[1];
final String type = dat[0];
Uri contentUri = null;

if (cursor != null && cursor.moveToFirst())
final int column_index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(column_index);
finally
if (cursor != null)
cursor.close();
return null;
【讨论】：
【参考方案6】：试试这个：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data)
Uri selectedImage = data.getData();
String[] filePathColumn = MediaStore.Images.Media.DATA ;
Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
System.out.println("picturePath +"+ picturePath ); //path of sdcard
【讨论】：
【参考方案7】：在这里我从 onActivityResult() 获取 uri
Uri selectedImageURI = data.getData();
String realPath = getRealPathFromURI(selectedImageURI);
1) 在片段中你可以像这样使用函数..
private String getRealPathFromURI(Uri contentURI)
String filePath;
Cursor cursor = getActivity().getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null)
filePath = contentURI.getPath();
else
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
filePath = cursor.getString(idx);
cursor.close();
return filePath;
2) 你可以使用这样的功能。
private String getRealPathFromURI(Uri contentURI)
String filePath;
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null)
filePath = contentURI.getPath();
else
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
filePath = cursor.getString(idx);
cursor.close();
return filePath;
【讨论】：
【参考方案8】：这里是如何通过 MediaStore 从 Uri 获取文件的真实路径::
private String getRealPathFromURI(Context context, Uri contentUri)
Cursor cursor = null;
try
String[] proj = MediaStore.Images.Media.DATA ;
cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
catch (Exception e)
Log.e(TAG, "getRealPathFromURI Exception : " + e.toString());
return "";
finally
if (cursor != null)
cursor.close();
【讨论】：
这不适用于 Android 10 或更高版本，因为无法再访问DATA。它在早期版本的 Android 上不可靠。
这是否适用于其他文件类型，例如音频？正如@CommonsWare 所说，DATA 已被弃用
MediaStore.Images.Media.DATA 已弃用【参考方案9】：
这样称呼
Uri selectedImageURI = data.getData(); //where data is intent return by onActivityResult
imageFile = new File(getRealPathFromURI(selectedImageURI));
以及获取路径的代码..
private String getRealPathFromURI(Uri contentURI)
String result = null;
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null)
// Source is Dropbox or other similar local file path
result = contentURI.getPath();
else
if(cursor.moveToFirst())
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
result = cursor.getString(idx);
cursor.close();
return result;
【讨论】：
java.lang.IllegalStateException: 无法从 CursorWindow 读取第 0 行 col -1。确保在从光标访问数据之前正确初始化光标。【参考方案10】：我找到了更优雅的解决方案：
Uri file_uri = Uri.parse(videoURI); // parse to Uri if your videoURI is string
String real_path = file_uri.getPath(); // will return real file path
【讨论】：
【参考方案11】：对于 Kotlin 人来说，这段代码对我有用
fun getPath(context: Context, uri: Uri): String?
val isKitKatorAbove = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT
// DocumentProvider
if (isKitKatorAbove && DocumentsContract.isDocumentUri(context, uri))

您可以在 utils 类中添加这些方法

【参考方案12】：我试图解决这个问题 2/3 天，但我找到的所有可能的解决方案都没有帮助。我不断收到空游标和类似错误。
我需要文件路径的原因是为了获取 Exif 数据，以便我可以以正确的方向显示图像。 （见A final answer on how to get Exif data from URI）
我找到了这个开源项目-
https://github.com/ArthurHub/Android-Image-Cropper/blob/master/cropper/src/main/java/com/theartofdev/edmodo/cropper/BitmapUtils.java
有一种方法可以从 InputStream 中获取 Exif 数据，这解决了我的问题 -
ExifInterface ei = null;
try
InputStream is = context.getContentResolver().openInputStream(uri);
if (is != null)
ei = new ExifInterface(is);
is.close();
catch (Exception ignored)
我知道这不是直接回答问题，但由于我通过尝试解决这个问题找到了这个帖子，我认为我的回答可能对其他人有所帮助。

【讨论】：
以上代码在 android 所有设备以及所有类型的文件路径都可以在内部和外部打开，谷歌驱动器，gallery 等。请注意，请记住在 android 清单中添加文件提供程序。 它在来自设备外部存储的文件的情况下提供 NPE，uriString 为 content://media/external/file...。我已经修复了它以获取 pdf 文档。【参考方案14】：

【讨论】：
您好，在我的情况下，它进入 isDownloadDocument 路径，但 _id 是 msf:24，而不是原始：& 不是数字。因此在使用 Long.valueOf 时会抛出错误，您能帮忙吗？【参考方案15】：我在 Android 10 中遇到了同样的问题，
因为我的文件 URI 包含 msf: 格式。
大多数解决方案都说将文件复制到缓存路径中，然后使用该路径。
因此，这里是获取路径的解决方案，无需复制。
if (isAndroid10 && id.startsWith("msf:"))
final String[] split = id.split(":");
final String selection = "_id=?";
final String[] selectionArgs = new String[] split[1] ;
return getDataColumn(context, MediaStore.Downloads.EXTERNAL_CONTENT_URI, selection, selectionArgs);
尝试实现这一点。
MediaStore.Downloads.EXTERNAL_CONTENT_URI -- ONLY PRESENT FROM ANDROID 10

这行不通。 您好，由于我不是 Android 开发人员，这适用于我的应用程序。这就是我在此处发布此解决方案的原因。以上是关于获取 Uri Android 的真实路径的主要内容，如果未能解决你的问题，请参考以下文章
