Detect whether TextView in ListView is ellipsized

Question

I have a custom Adapter that renders some items in a ListView. I need to show an icon on the ListView's items, if the item's text is ellipsized, and hide it if there's enough room for the text to finish. I have access to the button in getView method of my adapter (where I set the text) but the ellipses are not added immediately upon setting the text.

Is there any way I can do this?

Here's my TextView markup:

<TextView android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:ellipsize="end"
          android:singleLine="true"
          android:id="@+id/list_item_description"/>

Answer 1

public int getEllipsisCount (int line):

Returns the number of characters to be ellipsized away, or 0 if no ellipsis is to take place.

So, simply call :

if(textview1.getLayout().getEllipsisCount() > 0) {
   // Do anything here..
}

Since the getLayout() cant be called before the layout is set, use ViewTreeObserver to find when the textview is loaded:

ViewTreeObserver vto = textview.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
       Layout l = textview.getLayout();
       if ( l != null){
          int lines = l.getLineCount();
          if ( lines > 0)
              if ( l.getEllipsisCount(lines-1) > 0)
                Log.d(TAG, "Text is ellipsized");
       }  
    }
});

And finally do not forget to remove removeOnGlobalLayoutListener when you need it nomore.
