Question

Is there a way to highlight a word in a TextView, so you can click it and an other Activity starts? I want to make a kind of dictionary App and some Word in the definitions aren’t self-explaining, so i thought when i highlight them and the user could click them, an other activity should start with an other definition.

Thanks.

Give you a demo：

public class TextViewDemo extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            TextView txtInfo = new TextView(this);
            SpannableString ss = new SpannableString("helloworldandroid:.");
            ss.setSpan(new ForegroundColorSpan(Color.RED), 0, 2,
                            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            ss.setSpan(new URLSpan("tel:[phone]"), 2, 5,
                            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            ss.setSpan(new StyleSpan(Typeface.BOLD_ITALIC), 5, 7,
                            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            ss.setSpan(new StrikethroughSpan(), 7, 10,
                            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            ss.setSpan(new UnderlineSpan(), 10, 16,
                            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            ss.setSpan(new ForegroundColorSpan(Color.GREEN), 10, 15,
                            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            Drawable d = getResources().getDrawable(R.drawable.ic_launcher);
            d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
            ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE);
            ss.setSpan(span, 18, 19, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
            txtInfo.setText(ss);
            txtInfo.setMovementMethod(LinkMovementMethod.getInstance());
            setContentView(txtInfo);
    }

}
