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，但在安卓4.4中并没有让人耳目一新。以编程方式添加/删除图像时如何刷新库？

尝试以下操作：

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"); //OR  File f = new File(YourCurrentPhotoPath);
    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")));
}

就是这样…
