SpannableString with Image example

Question

I am looking for an example of how to build and display Android SpannableString with ImageSpan. Something like inline display of smileys.

Thanks a lot.

Solution 1

Found the following and it seems to do the job:

public class TestActivity extends Activity { 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    TextView textView  = (TextView) findViewById(R.id.textview); 
    SpannableString ss = new SpannableString("abc"); 
    Drawable d = ContextCompat.getDrawable(this, R.drawable.icon32);
    d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight()); 
    ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE); 
    ss.setSpan(span, 0, 3, Spannable.SPAN_INCLUSIVE_EXCLUSIVE); 
    textView.setText(ss); 
} 

Solution 2

SpannableString + ImageSpan don't work in Android API 21 & 22 (I tested in Android Studio 1.2.1.1 in emulator), but if you do this:

TextView textView  = (TextView) findViewById(R.id.textview);
textView.setTransformationMethod(null);
...
textView.setText(ss); 

SpannableString + ImageSpan will work.
