在Android中将文件path转换为Uri

我有一个应用程序,使用相机捕捉video。 我可以得到video的文件path,但我需要它作为一个Uri。

我得到的文件path:

/storage/emulated/0/DCIM/Camera/20141219_133139.mp4 

我需要的是这样的:

 content//media/external/video/media/18576. 

这是我的代码。

 protected void onActivityResult(int requestCode, int resultCode, Intent data) { // if the result is capturing Image if (requestCode == CAMERA_CAPTURE_VIDEO_REQUEST_CODE) { if (resultCode == RESULT_OK) { // video successfully recorded // preview the recorded video // selectedImageUri = data.getData(); // Uri selectedImage = data.getData(); previewVideo(); tv1.setText(String.valueOf((fileUri.getPath()))); String bedroom=String.valueOf((fileUri.getPath())); Intent i = new Intent(); i.putExtra(bhk1.BEDROOM2, bedroom); setResult(RESULT_OK,i); btnRecordVideo.setText("ReTake Video"); } else if (resultCode == RESULT_CANCELED) { // user cancelled recording Toast.makeText(getApplicationContext(), "User cancelled video recording", Toast.LENGTH_SHORT) .show(); } else { // failed to record video Toast.makeText(getApplicationContext(), "Sorry! Failed to record video", Toast.LENGTH_SHORT) .show(); } } } 

我需要一个来自stringvariablesbedroom的Uri。 谢谢!

请尝试下面的代码

 Uri.fromFile(new File("/sdcard/sample.jpg")) 

下面的代码在18 API之前工作正常: –

 public String getRealPathFromURI(Uri contentUri) { // can post image String [] proj={MediaStore.Images.Media.DATA}; Cursor cursor = managedQuery( contentUri, proj, // Which columns to return null, // WHERE clause; which rows to return (all rows) null, // WHERE clause selection arguments (none) null); // Order-by clause (ascending by name) int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToFirst(); return cursor.getString(column_index); } 

以下代码在kitkat上使用: –

 public static String getPath(final Context context, final Uri uri) { final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT; // DocumentProvider if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) { // ExternalStorageProvider 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 } // DownloadsProvider else if (isDownloadsDocument(uri)) { final String id = DocumentsContract.getDocumentId(uri); final Uri contentUri = ContentUris.withAppendedId( Uri.parse("content://downloads/public_downloads"), Long.valueOf(id)); return getDataColumn(context, contentUri, null, null); } // 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 getDataColumn(context, uri, null, null); } // File else if ("file".equalsIgnoreCase(uri.getScheme())) { return uri.getPath(); } return null; } /** * Get the value of the data column for this Uri. This is useful for * MediaStore Uris, and other file-based ContentProviders. * * @param context The context. * @param uri The Uri to query. * @param selection (Optional) Filter used in the query. * @param selectionArgs (Optional) Selection arguments used in the query. * @return The value of the _data column, which is typically a file path. */ public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) { Cursor cursor = null; final String column = "_data"; final String[] projection = { column }; try { cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, 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; } /** * @param uri The Uri to check. * @return Whether the Uri authority is ExternalStorageProvider. */ public static boolean isExternalStorageDocument(Uri uri) { return "com.android.externalstorage.documents".equals(uri.getAuthority()); } /** * @param uri The Uri to check. * @return Whether the Uri authority is DownloadsProvider. */ public static boolean isDownloadsDocument(Uri uri) { return "com.android.providers.downloads.documents".equals(uri.getAuthority()); } /** * @param uri The Uri to check. * @return Whether the Uri authority is MediaProvider. */ public static boolean isMediaDocument(Uri uri) { return "com.android.providers.media.documents".equals(uri.getAuthority()); }
