Does that help You don't want your ViewHolder to be a global variable. Remove that and it's instantiation from the constructor. Instead you only ever want it to be a local variable to the getView method. Eg:
code :
public View getView(final int position, View convertView, ViewGroup parent) {
    ViewHolder holder;
    if(convertView==null) {
        holder = new ViewHolder();
        //Continue with handling view creation
    } else {
        holder = (ViewHolder) convertView.getTag();

GridView shuffles views after updating

GridView shuffles views after updating

I hope this helps . It comes from inner realization of BaseAdapter. It seems it stores views in stack or something like that so after the screen updating it places the views in the reverse order. The solution is to speed up data refreshing as much as possible. And remember that you shouldn't use async data refreshing: it will cause blinking.

I wish did fix the issue. You're comparing iPad's RAM and your machine's RAM.It's not fair though.
code :
[NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(reloadGrid123) userInfo:nil repeats:NO];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

//  Do something taking a long time in background.

    [NSThread sleepForTimeInterval:0.2];

    //  Background thread has finished it's work.
    //  Call another block on main thread to do UI stuff like updating etc..
    dispatch_async(dispatch_get_main_queue(), ^{
        //  Here you are in the main thread again
        //  You can do whatever you want

With these it helps I am working with Custom GridView where I am having 2 columns of images. When I scroll the Grid down to the next records and returns to the first row of records, my records got shuffle with in a row from its position. , The viewholder pattern works this way, in getView :
code :
ViewHolder holder = null;
if (convertView == null) {
    convertView = inflater.inflate(R.layout.myLayout, null);
    holder = new ViewHolder();
    // Populate the holder
    holder.textView = (TextView) convertView.findViewById(R.id.myTextView);
    holder.imageView = (ImageView) convertView.findViewById(R.id.myImageView);
} else {
    holder = (ViewHolder) convertView.getTag();
// Now, populate the views referenced by the viewHolder:
holder.textView.setText("Hello World");

it fixes the issue I've got a view that has a GridView with Image Buttons and Textviews but whenever the textviews that are multi line the items are not lining up as shown below. I could set the TextView as , The solution is as below

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:scaleType="fitCenter" />

ListViewAdapter shuffles items

wish of those help When you scroll the ListView recycles old views. But you are only updating the value only when a new row is inflated. Inflation of a new row does not occur all the time, it reuses an old row. This this the reason you are seeing old values again. Move the line viewHolder.cityUid.setText(); below the if-else block as below.
code :
public View getView(int position, View convertView, ViewGroup parent) {
    // Get the data item for this position
    LivingCity city = getItem(position);
    ViewHolder viewHolder; 

    if (convertView == null) {
        viewHolder = new ViewHolder();
        LayoutInflater inflater = LayoutInflater.from(getContext());
        convertView = inflater.inflate(R.layout.object_main_citydetailsrow, parent, false);

        viewHolder.cityUid  = (TextView) convertView.findViewById(R.id.cityrow_uid);
    } else {
        viewHolder = (ViewHolder) convertView.getTag();

    //city.getUid() returns an int
    viewHolder.cityUid.setText(String.format(Locale.ENGLISH,"#%d", city.getUid()));

    // Return the completed view to render on screen
    return convertView;
