Question

有没有办法在动作栏中设置倒数计时器的进度条？
我可以通过

在操作栏中启用进度条

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setContentView(...);
setProgressBarIndeterminateVisibility(true);

我可以通过

在MenuItem中设置倒数计时器（TextView）

private void startTimer(long duration, long interval) {

    timer = new CountDownTimer(duration, interval) {

        @Override
        public void onFinish() {
            //Kills current Activity        
            finish();
        }

        @Override
        public void onTick(long millisecondsLeft) {
            int secondsLeft = (int) Math.round((millisecondsLeft / (double) 1000));
            MenuItem timerItem = mMenu.findItem(R.id.timer_item);//Where mMenu is the menu inflated
            timerItem.setTitle(secondsLeft+"");

        }
    };

    timer.start();
}

menu.xml文件

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:compatibility="http://schemas.android.com/apk/res-auto" >

<item
    android:id="@+id/timer_item"
    name="android:actionMenuTextAppearance"
    android:showAsAction="always"
    compatibility:actionViewClass="android.widget.TextView"/>

</menu>

任何人都可以建议我如何整合这两个一个带倒数计时器的进度条（在操作栏上）??
