Android: ClickableSpan in clickable TextView

I have a textview that can contain clickable links. When one of this links is clicked, I want to start an activity. This works fine, but it should also be possible to click the whole textview and start another activity.

So that's my current solution:

    TextView tv = (TextView)findViewById(R.id.textview01);      
    Spannable span = Spannable.Factory.getInstance().newSpannable("test link span");   
    span.setSpan(new ClickableSpan() {  
        @Override
        public void onClick(View v) {  
            Log.d("main", "link clicked");
            Toast.makeText(Main.this, "link clicked", Toast.LENGTH_SHORT).show(); 
        } }, 5, 9, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    tv.setText(span); 

    tv.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d("main", "textview clicked");
            Toast.makeText(Main.this, "textview clicked", Toast.LENGTH_SHORT).show();               
        }
    });

    tv.setMovementMethod(LinkMovementMethod.getInstance());

The problem is, that when I set an OnClickListener, everytime I click on a link first the listener for the whole textview and then the one for the ClickableSpan is called.

Is there a way to prevent android from calling the listener for the whole textview, when a link is clicked? Or to decide in the listener for the whole view, if a link was clicked or not?

Found a workaround that is quite straight forward. Define ClickableSpan on all the text areas that are not part of the links and handle the click on them as if the text view was clicked:

TextView tv = (TextView)findViewById(R.id.textview01);      
Spannable span = Spannable.Factory.getInstance().newSpannable("test link span");   
span.setSpan(new ClickableSpan() {  
    @Override
    public void onClick(View v) {  
        Log.d("main", "link clicked");
        Toast.makeText(Main.this, "link clicked", Toast.LENGTH_SHORT).show(); 
    } }, 5, 9, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

// All the rest will have the same spannable.
ClickableSpan cs = new ClickableSpan() {  
    @Override
    public void onClick(View v) {  
        Log.d("main", "textview clicked");
        Toast.makeText(Main.this, "textview clicked", Toast.LENGTH_SHORT).show(); 
    } };

// set the "test " spannable.
span.setSpan(cs, 0, 5, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

// set the " span" spannable
span.setSpan(cs, 6, span.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

tv.setText(span);

tv.setMovementMethod(LinkMovementMethod.getInstance());

Hope this helps (I know this thread is old, but in case anyone sees it now...).
