Question

我的一个应用程序活动是幻灯片放映，许多动画取决于用户选择，如果用户取消选中它将打开寻呼机活动，下面的代码工作完美，但我必须用（if和if else）方法重复代码很多次对于每个冗余的动画，有没有办法设置一个方法并为每个动画调用它，如果未选中，则所有动画都将打开寻呼机活动，

任何帮助将不胜感激。

SlideShow.java

public class SlideShow extends Activity {

public int currentimageindex=0;

        public void run() {

            AnimateandSlideShow();              
        }
    };

    int delay = 1000; // delay for 1 sec.

    int period = 8000; // repeat every 4 sec.

    Timer timer = new Timer();

    timer.scheduleAtFixedRate(new TimerTask() {

    public void run() {

我会尝试这样的事情......

{
    ...
    boolean noPager = true;
    noPager = doAnim(R.anim.custom_anim, animation, noPager);
    noPager = doAnim(R.anim.fade_in, animation_one, noPager);
    noPager = doAnim(R.anim.fade_out, animation_two, noPager);
    noPager = doAnim(R.anim.bounce, animation_three, noPager);
    noPager = doAnim(R.anim.fade_in_2, animation_four, noPager);
    noPager = doAnim(R.anim.flip, animation_five, noPager);
    if(!noPager){
        Intent intent = new Intent(SlideShow.this, ImagePager.class);                                     
        startActivity(intent);
    }
}

private boolean doAnim(int anim, boolean yes_no, boolean notDone){
    if(!yes_no || !notDone){
        return true;
    }
    slidingimage = (ImageView)findViewById(R.id.ImageView_slide);
    slidingimage.setImageResource(IMAGE_IDS[currentimageindex%IMAGE_IDS.length]);       
    currentimageindex++;
    Animation rotateimage = AnimationUtils.loadAnimation(this, anim);       
    slidingimage.startAnimation(rotateimage);
    return false;
}
