试试这个：

TextView Timer;
int i ;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_player);

    Timer = (TextView)findViewById(R.id.textView1);

    final int length = 50;
    Thread t = new Thread(new Runnable() {

        @Override
        public void run() {
            for (  i = 0; i < length; i++) {
                runOnUiThread(new Runnable() {

                    @Override
                    public void run() {
                        Timer.setText(new Integer(i).toString());
                    }
                });

                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }
    });
    t.start();
    }
