        @Override
        public void onCheckedChanged(final CompoundButton buttonView, boolean isChecked) {
            if (isChecked) {
                new AlertDialog.Builder(mContext, R.style.AppCompatAlertDialogStyle).setTitle("Warning").setMessage("You want to whiteList this application?").setPositiveButton("YES", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {

                        //retrieve data from shared preference
                        String jsonScore = sharedPreference.getAppsArrayListData();
                        Type type = new TypeToken<ArrayList<WhiteListModel>>() {
                        }.getType();
                        existingDataSet = gson.fromJson(jsonScore, type);

                        //Adding items in Dataset
                        AllAppList appList = listStorage.get(position);
                        whiteListModel.setName(appList.getName());
                        whiteListModel.setPackName(appList.getPackName());


                        if (existingDataSet != null) {
                            existingDataSet.add(whiteListModel);
                            saveScoreListToSharedpreference(existingDataSet);
                        } else {
                            newDataSet.add(whiteListModel);
                            saveScoreListToSharedpreference(newDataSet);
                        }

                        //Notifying adapter data has been changed.....
                        notifyDataSetChanged();
                        listViewHolder.switchCompat.setChecked(false);


                    }
                }).setNegativeButton("No", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        listViewHolder.switchCompat.setChecked(false);
                    }
                }).show();

            }

        }
    });

code of listview click:-

private List<AllAppList> getInstalledApps() {
    List<AllAppList> res = new ArrayList<AllAppList>();
    List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
    for (int i = 0; i < packs.size(); i++) {
        PackageInfo p = packs.get(i);
        if ((!isSystemPackage(p))) {
            if (p.applicationInfo.packageName.equalsIgnoreCase("com.soopermo.batterybooster")){
                continue;
            }
            boolean isWhiteList = false;
            if (whiteListModels != null) {
                for (int j = 0; j < whiteListModels.size(); j++) {
                    model = whiteListModels.get(j);
                    Log.e(TAG, "p*****" + model.getPackName());
                    if (p.applicationInfo.packageName.equalsIgnoreCase(model.getPackName())) {
                        // This package is whitlist package
                        isWhiteList = true;
                        //Here is want to enable/disable switch

                    }
                }
            }

Do it via a model class.

Item.java

public class Item{
    private String appName;
    private boolean isEnable;
    public String getAppName(){
        return this.appName;
    }
    public void setAppName(String name){
        this.appName = name;
    }
    public boolean isEnabled(){
        return this.isEnabled;
    } 
    public void setEnabled(boolean value){
        this.isEnabled = value;
    }
}

MainActivity.java

List<Item> myItems = new ArrayList<>();
...
..onCreate(Bundle savedInstance){
 ...//your code
YourAdapter adapter = new YourAdapter(MainActivity.this, myItems);//pass the list of items.
yourListView.setAdapter(adapter);

//your action call when you want to trigger the change suppose 2nd item has to be enabled.
myItems.get(1).setEnabled(true);

//and after that notify this change to your adapter
adapter.notifyDataSetChanged();

}

YourAdapter.java

List<Items> itemList;
Context context;

public YourAdapter(Context context, List<Items> itemList){
    this.context = context;
    this. itemList = itemList;
}

public View getView(int position, View convertView, ViewGroup parent){
    ...//you code to inflate your view
    Items item = itemList.get(position);

    if(item.isEnabled()){
        //toggle your switch.
    }

}

my Item.java is same as your AllApplist.java, simply put a boolean in it and do it as it is done in the code..
