在这里,这个 renameFile(..) 函数在 Android API 30 中工作。但是,它在 Android API 29 中不起作用,并显示如下错误:
java.lang.IllegalArgumentException:不允许移动不属于明确定义的集合的内容://media/external/file/116
更新说明:
---开始---
为了使用 sdk-29,我们必须使用 Uri 作为 extUri = MediaStore.Downloads.getContentUri(MediaStore.VOLUME_EXTERNAL),例如:
private static Uri extUri = MediaStore.Downloads.getContentUri(MediaStore.VOLUME_EXTERNAL);
代替下面的代码。并更新 MediaStore.Files.FileColumns 至 MediaStore.Downloads ---结束---
Uri extUri = MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL);
String relativeLocation = Environment.DIRECTORY_DOWNLOADS + File.separator + "AppFolder";
函数重命名文件(...) boolean renameFile(Context context, String newName, String displayName) {
try {
Long id = getIdFromDisplayName(displayName);
ContentResolver contentResolver = context.getContentResolver();
Uri mUri = ContentUris.withAppendedId(extUri, id);
ContentValues contentValues = new ContentValues();
contentValues.put(MediaStore.Files.FileColumns.IS_PENDING, 1);
contentResolver.update(mUri, contentValues, null, null);
contentValues.clear();
contentValues.put(MediaStore.Files.FileColumns.DISPLAY_NAME, newName);
// contentValues.put(MediaStore.Files.FileColumns.MIME_TYPE, "files/pdf");
// contentValues.put(MediaStore.Files.FileColumns.RELATIVE_PATH, relativeLocation);
// contentValues.put(MediaStore.Files.FileColumns.TITLE, "SomeName");
// contentValues.put(MediaStore.Files.FileColumns.DATE_ADDED, System.currentTimeMillis() / 1000);
// contentValues.put(MediaStore.Files.FileColumns.DATE_TAKEN, System.currentTimeMillis());
contentValues.put(MediaStore.Files.FileColumns.IS_PENDING, 0);
contentResolver.update(mUri, contentValues, null, null);
return true;
} catch (Exception ex) {
ex.printStackTrace();
}
return false;
}
函数 getIdFromDisplayName(...) @RequiresApi(api = Build.VERSION_CODES.Q)
Long getIdFromDisplayName(String displayName) {
String[] projection;
projection = new String[]{MediaStore.Files.FileColumns._ID};
// TODO This will break if we have no matching item in the MediaStore.
Cursor cursor = getContentResolver().query(extUri, projection,
MediaStore.Files.FileColumns.DISPLAY_NAME + " LIKE ?", new String[]{displayName}, null);
assert cursor != null;
cursor.moveToFirst();
if (cursor.getCount() > 0) {
int columnIndex = cursor.getColumnIndex(projection[0]);
long fileId = cursor.getLong(columnIndex);
cursor.close();
return fileId;
}
return null;
}
最佳答案
java.lang.IllegalArgumentException: Movement of content://media/external/file/116 which isn't part of well-defined collection not allowed
因此,如果您使用该集合,则对于 Android Q 是不允许的;但是对于“定义明确的集合”是允许的,例如:Uri extUri = MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL);
我留给你去寻找其他定义明确的集合。Uri extUri = MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL); // Use "Pictures/MyFolder" for RELATIVE_PATH
为什么这仅适用于我不知道的 Android Q。

引用:如果重命名失败,请使用 SAF(如前所述)。 How to rename a file in Android knowing only its media content Uri// We only support movement under well-defined collections switch (match) { case AUDIO_MEDIA_ID: case VIDEO_MEDIA_ID: case IMAGES_MEDIA_ID: case DOWNLOADS_ID: break; default: throw new IllegalArgumentException("Movement of " + uri + " which isn't part of well-defined collection not allowed"); }
关于java - 重命名由应用程序在 android 10 中创建的 Mediastore 文件。在 Android API 30 上工作,但在 API 29 中显示错误,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/63543414/
