android - 在android kitkat中刷新画廊

Question

如何在 android kitkat 中刷新图库？

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory())));

我尝试了上面的方法，但它在 android 4.4 中没有刷新。以编程方式添加/删除图像时如何刷新图库？

这对我有用:)

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File("folderPATH", "fileName");
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    appContext.sendBroadcast(mediaScanIntent);
} else {
    appContext.sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory() + "/" + "FOLDER_TO_REFRESH")));
}

希望对您有所帮助:)
