ListView with alphabets on the right like Sony Xperia Contacts, is it possible?
I searched for one day to find an example or library that can do this for me, see below:
If you are a Sony Xperia user, you know exactly what I am asking for, as you can see in the picture, the user can touch the alphabets and move them to the left. Moving on, the alphabets will be larger.
I have seen several questions on stackoverflow, but none of them matched my requirement. And what I have tried is the same as usual.
Here is a question about StackOverFlow: ListView with alphabet .... And there are many other links I read, I can provide one too.

To do this you need a ListView
custom header with support.
If you don't want your hand to be messy and look like a much simpler solution, try this library called SuperSLIM.
See example below,
You can check out the default sample application that demonstrates the use of a custom title, especially in alphabetical order.
https://github.com/TonicArtos/SuperSLiM/tree/early_release_4/example
See an example from the demo app for implementing the title in alphabetical order,
public CountryNamesAdapter(Context context, int headerMode) {
mContext = context;
final String[] countryNames = context.getResources().getStringArray(R.array.country_names);
mHeaderDisplay = headerMode;
mItems = new ArrayList<>();
//Insert headers into list of items.
String lastHeader = "";
int sectionManager = -1;
int headerCount = 0;
int sectionFirstPosition = 0;
for (int i = 0; i < countryNames.length; i++) {
String header = countryNames[i].substring(0, 1);
if (!TextUtils.equals(lastHeader, header)) {
// Insert new header view and update section data.
sectionManager = (sectionManager + 1) % 2;
sectionFirstPosition = i + headerCount;
lastHeader = header;
headerCount += 1;
mItems.add(new LineItem(header, true, sectionManager, sectionFirstPosition));
}
mItems.add(new LineItem(countryNames[i], false, sectionManager, sectionFirstPosition));
}
}
