android file转换,Android 将Uri转换成File

今天在项目中遇到将返回的Uri类型转换成File。将其写成一个方法：

private File uri2File(Uri uri) {

String img_path;

String[] proj = {MediaStore.Images.Media.DATA};

Cursor actualimagecursor = managedQuery(uri, proj, null,

null, null);

if (actualimagecursor == null) {

img_path = uri.getPath();

} else {

int actual_image_column_index = actualimagecursor

.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);

actualimagecursor.moveToFirst();

img_path = actualimagecursor

.getString(actual_image_column_index);

}

File file = new File(img_path);

return file;

}
