Core

Write SocialTextView or SocialEditText in xml.

<com.hendraanggrian.appcompat.widget.SocialTextView
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="#hashtag and @mention."
    app:socialFlags="hashtag|mention"
    app:hashtagColor="@color/blue"
    app:mentionColor="@color/red"/>

See attrs.xml for full list of available attributes.

Modify its state and set listeners programmatically.

textView.setMentionEnabled(false);
textView.setHashtagColor(Color.RED);
textView.setOnHashtagClickListener(new Function2<SocialView, String, Unit>() {
    @Override
    public Unit invoke(SocialView socialView, String s) {
        // do something
        return null;
    }
});

Any TextView or subclasses of TextView can be made social, see SocialTextView.kt for example.

Commons

NOTE: Custom adapters are experimental, see demo for example.

Write SocialAutoCompleteTextView in xml.

<com.hendraanggrian.appcompat.widget.SocialAutoCompleteTextView
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="What's on your mind?"
    app:socialFlags="hyperlink"
    app:hyperlinkColor="@color/green"/>

To display suggestions, it is required to setHashtagAdapter() and setMentionAdapter().

ArrayAdapter<Hashtag> hashtagAdapter = new HashtagAdapter(getContext());
hashtagAdapter.add(new Hashtag("follow"));
hashtagAdapter.add(new Hashtag("followme", 1000));
hashtagAdapter.add(new Hashtag("followmeorillkillyou", 500));
textView.setHashtagAdapter(hashtagAdapter);

ArrayAdapter<Mention> mentionAdapter = new MentionAdapter(getContext());
mentionAdapter.add(new Mention("dirtyhobo"));
mentionAdapter.add(new Mention("hobo", "Regular Hobo", R.mipmap.ic_launcher));
mentionAdapter.add(new Mention("hendraanggrian", "Hendra Anggrian", "https://avatars0.githubusercontent.com/u/11507430?v=3&s=460"));
textView.setMentionAdapter(mentionAdapter);

To customize hashtag or mention adapter, create a custom adapter using customized SocialAdapter or write your own ArrayAdapter.

public class Person {
    public final String name;

    public Person(String name) {
        this.name = name;
    }
}

// easier
public class PersonAdapter extends SocialAdapter<Person> {

    public PersonAdapter(@NonNull Context context) {
        super(context, R.layout.item_person, R.id.textview_person);
    }

    @Override
    public String convertToString(Person $receiver) {
        return $receiver.name;
    }

    @Override
    public View getView(int position, View convertView, @NonNull ViewGroup parent) {
        ...
    }
}

// this works too
public class PersonAdapter extends ArrayAdapter<Person> {
    // your own adapter layout, view holder, data binding
    // and of course, filtering logic
}

Then, use the custom adapter.

ArrayAdapter<Person> adapter = new PersonAdapter(getContext());
adapter.add(personA);
adapter.add(personB);
textView.setMentionAdapter(adapter);
