如何使图像同时闪烁？

Question

我有5张图片，我想要img1＆amp; img2同时闪烁3秒，然后img3＆amp; img4同时闪烁3秒。但是，我希望img5保持静态3秒，然后整个过程从头再次开始。

我的部分代码：

public class MainActivity extends Activity
{

 ...
    img1=(ImageView) findViewById(R.id.imageView1);
    img2=(ImageView) findViewById(R.id.imageView2);
    img3=(ImageView) findViewById(R.id.imageView3);
    img4=(ImageView) findViewById(R.id.imageView4);
    img5=(ImageView) findViewById(R.id.imageView5);


    img2.setVisibility(View.GONE);
    img3.setVisibility(View.GONE);
    ....

    anim = new AlphaAnimation(0.0f, 1.0f);
    anim.setDuration(500); //You can manage the time of the blink with this parameter
    anim.setStartOffset(30);
    anim.setRepeatMode(Animation.REVERSE);
    anim.setRepeatCount(20);

    ...

   img1.startAnimation(anim);

    AnimationListener animListener = new AnimationListener()
    {

        @Override
        public void onAnimationEnd(Animation arg0) {
            // TODO Auto-generated method stub
            img1.setVisibility(View.GONE);
            img2.setVisibility(View.VISIBLE);
            img2.startAnimation(anim2);
        }

        @Override
        public void onAnimationRepeat(Animation animation) {

        }

        @Override
        public void onAnimationStart(Animation animation) {

        }

    }; 
}

使用Handler将img5静态保持3秒钟，然后开始动画。

final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
    @Override
    public void run() {
        // animateImg5();
    }
}, 3000);
