Ideally an adapter is an object to adapt a particular dataset to render a view within a listview. So you should have a data structure (class object) for every row visible in that list view and put it in an array list. Based on the position in getView method, retrieve the data for the row and initialize views from this data. Now this data set can be saved on server or in local memory in any format preferably in JSON and can be retrieved back in future.

RecyclerView lags on scrolling

I'm having an issue where when the RecyclerView has a big amount of items (say 2000) the scrolling is really laggy.
I would be really really thankful if someone helps me improving it. Thanks in advance.
EDIT: The lag may be caused when using this FastScroll library. If someone is able to do some pull requests to improve it, I'm sure the dev will be really thankful. https://github.com/plusCubed/recycler-fast-scroll

From your comment you have mentioned that, you are not using any library for loading images, that's might be the issue, since libraries like Picasso ,glide... Use an asynctask to load images load on the main that is refused. You can do the same by writing it yourself but you will end up re-inventing the wheel again

How big are the images? Try to downscale them (for example resize through Picasso)

How to add a listview item to a whole other listview

So in my android app, I have two scrollable tabs which each contain Listview using a Fragment. One a list of apps and the other is blank. What I am aiming to do is add a plus button in place of where my checkbox is and duplicate that item in the other listview which is blank.
I have done research on this, but I have not found any successful examples on how to implement this.

}
#Override

if (convertView == null) {

.findViewById(R.id.appname);
holder.ck1 = (CheckBox) convertView
.findViewById(R.id.checkBox1);
convertView.setTag(holder);
//holder.ck1.setTag(packageList.get(position));
} else {

}
// ViewHolder holder = (ViewHolder) convertView.getTag();
PackageInfo packageInfo = (PackageInfo) getItem(position);
Drawable appIcon = packageManager
.getApplicationIcon(packageInfo.applicationInfo);
String appName = packageManager.getApplicationLabel(
packageInfo.applicationInfo).toString();
appIcon.setBounds(0, 0, 75, 75);
holder.apkName.setCompoundDrawables(appIcon, null, null, null);
holder.apkName.setCompoundDrawablePadding(15);
holder.apkName.setText(appName);
holder.ck1.setChecked(false);
if (itemChecked[position])
holder.ck1.setChecked(true);
else
holder.ck1.setChecked(false);
holder.ck1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (holder.ck1.isChecked())

}
});
return convertView;
}
}
How would I go about achieving this?

So what you are doing is, you are populating a listview of installed apps using package manager. Add a plus button in place of the checkbox. Now get installed apps similar to this -
List<PackageInfo> packageList1 = packageManager.getInstalledPackages(0);
final PackageItemInfo.DisplayNameComparator comparator = new PackageItemInfo.DisplayNameComparator(packageManager);
Collections.sort(packageList1, new Comparator<PackageInfo>() {
#Override
public int compare(PackageInfo lhs, PackageInfo rhs) {
return comparator.compare(lhs.applicationInfo, rhs.applicationInfo);
}
});
for (int i = 0; i < packageList1.size(); i++) {
PackageInfo PackInfo = packageList1.get(i);
if (((PackInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) != true) {
//Add to adapter
}
}
}
Now, create a public string array in the activity which is holding the tabs. When you click on the plus button add the packagename to the array.
Now on the other tab use the same adapter, but here before adding it to the adapter check if it is found in the string array using the index. Something like -
List<PackageInfo> packageList1 = packageManager.getInstalledPackages(0);
final PackageItemInfo.DisplayNameComparator comparator = new PackageItemInfo.DisplayNameComparator(packageManager);
Collections.sort(packageList1, new Comparator<PackageInfo>() {
#Override
public int compare(PackageInfo lhs, PackageInfo rhs) {
return comparator.compare(lhs.applicationInfo, rhs.applicationInfo);
}
});
for (int i = 0; i < packageList1.size(); i++) {
PackageInfo PackInfo = packageList1.get(i);
if (((PackInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) != true) {
if (Mainactivity.array contains String PackageName= PackInfo.packageName)
{
//Add to adapter
}
}
}
}
To persist the selected apps, add their package name to shared_preferences.
edit :
In your fragment's LoadApplications class, you retrieve a list of installed apps. On the second fragment use the same code, but just add one more condition
for(PackageInfo pi : packageList) {
boolean b = isSystemPackage(pi);
boolean c = isSystemPackage1(pi);
if(!b || !c ) {
if (array contains packagename){
packageList1.add(pi);
}
}

List<UserApps> packageListBlocked = new ArrayList<UserApps>();
holder.ck1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (holder.ck1.isChecked())
itemChecked[position] = true;
packageListBlocked.add(packageList.get(position));
else
itemChecked[position] = false;
}
});
ArrayList can hold duplicate data, so be cautious while adding.
Now you have all checkedItems in packageListBlocked pass it on to next tab and set data, make sure you call adapter.notifyDataSetChanged();

ApplicationAdapter error when trying to get installed apps

I am have scrollable tabs in my action bar and in one of those tabs I am trying to get a list of user installed apps and used system apps, like Flipoard, youtube, messaging etc. (eventually in alphabetical order)
I am trying to follow these, but I am having some errors implementing it because I am using fragments.

This is the current error I am getting.
I am not sure what I should do to resolve this error and successfully get a list of user installed and used system apps in alphabetical order in all in a fragment.
What can be done about my approach and how can I achieve this?

One of the arguments you're passing to the constructor of the super class, that is an ArrayAdapter, does not match with any of the ArrayAdapter's constructors.
I believe that argument is the the PackageManager appsList, you should instead pass a List<T> appsList to match the constructor defined here.

Android Beginner: ListView with Images and CheckBoxes

I am a beginner programmer so please bear with me. I have been able to create a listview with images in it and thought I could modify it to add a checkbox. However, this setup does not work. Any suggestions to how I may fix my code to create a listview with both an image and checkbox?
