android把视频文件添加到相册

//是否添加到相册
    ContentResolver localContentResolver = this.getContentResolver();
    ContentValues localContentValues = getVideoContentValues(this, file, System.currentTimeMillis());
    Uri localUri = localContentResolver.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, localContentValues);
    sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, localUri));
    public static ContentValues getVideoContentValues(Context paramContext, File paramFile, long paramLong)
    {
    　　ContentValues localContentValues = new ContentValues();
    　　localContentValues.put("title", paramFile.getName());
    　　localContentValues.put("_display_name", paramFile.getName());
    　　localContentValues.put("mime_type", "video/mp4");
    　　localContentValues.put("datetaken", Long.valueOf(paramLong));
    　　localContentValues.put("date_modified", Long.valueOf(paramLong));
    　　localContentValues.put("date_added", Long.valueOf(paramLong));
    　　localContentValues.put("_data", paramFile.getAbsolutePath());
    　　localContentValues.put("_size", Long.valueOf(paramFile.length()));
    　　return localContentValues;
    }
