Android获取Uri的正确文件路径的办法

public String getImagePathFromUri(final Context context, Uri picUri) {        // 选择的图片路径        String selectPicPath = null;        Uri selectPicUri = picUri;        final String scheme = picUri.getScheme();        if (picUri != null && scheme != null) {            if (scheme.equals(ContentResolver.SCHEME_CONTENT)) {                // content://开头的uri                Cursor cursor = context.getContentResolver().query(picUri, null, null, null, null);                if (cursor != null && cursor.moveToFirst()) {                    int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);                    // 取出文件路径                    selectPicPath = cursor.getString(columnIndex);                    // Android 4.1 更改了SD的目录，sdcard映射到/storage/sdcard0                    if (!selectPicPath.startsWith("/storage") && !selectPicPath.startsWith("/mnt")) {                        // 检查是否有"/mnt"前缀                        selectPicPath = "/mnt" + selectPicPath;                    }                    //关闭游标                    cursor.close();                }            } else if (scheme.equals(ContentResolver.SCHEME_FILE)) {// file:///开头的uri                // 替换file://                selectPicPath = selectPicUri.toString().replace("file://", "");                int index = selectPicPath.indexOf("/sdcard");                selectPicPath = index == -1 ? selectPicPath : selectPicPath.substring(index);                if (!selectPicPath.startsWith("/mnt")) {                    // 加上"/mnt"头                    selectPicPath = "/mnt" + selectPicPath;                }            }        }        return selectPicPath;    }
