Android Development: How To Replace Part of an EditText with a Spannable

Question

I\'m trying to replace part of an Editable returned from getText() with a span.

I\'ve tried getText().replace() but that\'s on

Answer 1

This minimal size example makes the word 'first' large:

public class SpanTest extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        String dispStr = "I'm the first line\nI'm the second line";
        TextView tv = (TextView) findViewById(R.id.textView1);
        int startSpan = dispStr.indexOf("first");
        int endSpan = dispStr.indexOf("line");
        Spannable spanRange = new SpannableString(dispStr);
        TextAppearanceSpan tas = new TextAppearanceSpan(this, android.R.style.TextAppearance_Large);
        spanRange.setSpan(tas, startSpan, endSpan, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        tv.setText(spanRange);
    }
}

You can adapt it to your needs
