TextView의 일부 문자를 만들어 주위의 편의류를 클릭했다.

편의류

import java.util.regex.Matcher;
import java.util.regex.Pattern;

import android.text.SpannableString;
import android.text.Spanned;
import android.text.style.ClickableSpan;
import android.util.SparseArray;
import android.view.View;

public class TextLinker {

    public interface OnLinkClickListener{
        public void onLinkClick(int textId);
    }

    private static class TextClickSpan extends ClickableSpan{

        private OnLinkClickListener mListener;
        private int mTextId;

        public TextClickSpan(int textId , OnLinkClickListener listener){
            mTextId = textId;
            mListener = listener;
        }

        @Override
        public void onClick(View widget) {
            if(mListener != null)mListener.onLinkClick(mTextId);
        }
    }

    public static SpannableString getLinkableText(String text , SparseArray<String> links , OnLinkClickListener listener){
        SpannableString spannable = new SpannableString(text);

        int size = links.size();
        for(int i = 0 ; i < size ; i++){
            int key = links.keyAt(i);
            String link = links.get(key);
            Pattern p = Pattern.compile(link);
            Matcher m = p.matcher(text);
            while(m.find()){
                TextClickSpan span = new TextClickSpan(key , listener);
                spannable.setSpan(span, m.start(), m.end(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            }
        }
        return spannable;
    }
}

사용법

    String text ="testhogehogeeeeeeehogefugaaaaagugapiyo";
    SparseArray<String> links = new SparseArray<String>();
    links.append(0, "hoge");
    links.append(1, "fuga");

    OnLinkClickListener listener = new OnLinkClickListener() {
        @Override
        public void onLinkClick(int textId) {
            // hogeをクリックするとtextIdは0、
            // fugaをクリックするとtextIdは1。
        }
    };

    TextView textView = (TextView)findViewById(R.id.text);
    textView.setText(TextLinker.getLinkableText(text, links, listener));
    textView.setMovementMethod(LinkMovementMethod.getInstance());

링크 색상을 변경할 때

<TextView
            android:id="@+id/text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textColor="@android:color/black"
            android:textColorLink="@android:color/holo_purple"
            />
