Android 获取图库图片 Uri 路径
问题描述：
在一个活动中，我可以从图库中选择一个图像，我需要它的 Uri 路径(在日志中，我的测试图像的 Uri 路径是 /content:/media/external/images/media/1).
In an Activity, I can choose an image from the Gallery, and I need its Uri path (in the log, the Uri path for my test image is /content:/media/external/images/media/1).
我收到了这个错误:
08-04 02:14:21.912: DEBUG/PHOTOUPLOADER(576): java.io.FileNotFoundException: /content:/media/external/images/media/1 (No such file or directory)
08-04 02:14:32.124: WARN/System.err(576): java.io.FileNotFoundException: /content:/media/external/images/media/1 (No such file or directory)
这是文件路径的正确格式吗?或者我应该让它像 sdcard...image.png 之类的东西?
Is this the correct format of a file path? Or should I make it to be something like sdcard...image.png?
答
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
startManagingCursor(cursor);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
