android - 如何在Android上省略活动标题

Question

我正在尝试省略活动的标题，有人可以告诉我该怎么做吗？

setTitle("My Title");
//when the text of the title gets too long, how can I use setEllipsize() here? how can I get the view Id of that title?

// make the title scroll!
         // find the title TextView
         TextView title = (TextView) findViewById(android.R.id.title);
         // set the ellipsize mode to MARQUEE and make it scroll only once

         title.setEllipsize(TruncateAt.MARQUEE);
         title.setMarqueeRepeatLimit(1);
         // in order to start strolling, it has to be focusable and focused
         title.setFocusable(true);
         title.setFocusableInTouchMode(true);
         title.requestFocus();
