Question

我想创建一个想要使用imageviewer显示多个图像的应用程序，但一次只能在屏幕上显示一个图像＆amp;第二个图像来点击按钮，我想要这个因为想要在图像进入屏幕时放动画。在这里，我尝试了轻扫图像的viewpager。是否有可能在使用viewpager时我们可以在屏幕上显示每个图像时放置动画。

这是我的完整活动代码

public class Numbers extends Activity {
    MediaPlayer mp;
    MediaPlayer BG;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_numbers);
        ViewPagerAdapter adapter = new ViewPagerAdapter(this, imageArra);
        ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager);
        myPager.setOnPageChangeListener(player);
        myPager.setAdapter(adapter);
        myPager.setCurrentItem(0);
        BG = MediaPlayer.create(this, R.raw.jingle);
        BG.setLooping(true);
        BG.setVolume(100, 100);
        BG.start();
        mp = MediaPlayer.create(Numbers.this, mAudio[0]);
        mp.start();
    }

    @Override
    protected void onPause() {
        super.onPause();
        BG.pause();
        }

    @Override
    protected void onResume() {
    super.onResume();
    BG.start();
    }

    private int[] mAudio = new int[]{R.raw.one,
                                     R.raw.two,
                                     R.raw.three,
                                     R.raw.four,
                                     R.raw.five,
                                     R.raw.six,
                                     R.raw.seven,
                                     R.raw.eight,
                                     R.raw.nine,
                                     R.raw.ten};

    private int imageArra[] =  {R.drawable.no1,
                                R.drawable.no2,
                                R.drawable.no3,
                                R.drawable.no4,
                                R.drawable.no5,
                                R.drawable.no6,
                                R.drawable.no7,
                                R.drawable.no8,
                                R.drawable.no9,
                                R.drawable.no10};

    public  OnPageChangeListener player = new OnPageChangeListener()
    {

        @Override
        public void onPageSelected(int arg1)
        {
        mp = MediaPlayer.create(Numbers.this, mAudio[arg1]);
        mp.start();
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2)
        {
        }

        @Override
        public void onPageScrollStateChanged(int arg0)
        {
        }
    };

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.numbers, menu);
        return true;
    }

}

请为我推荐教程或解决方案..

尝试使用以下代码在ViewPager

上提供动画

Timer timer = new Timer();

public void pageSwitcher(int seconds) {
    timer = new Timer(); // At this line a new Thread will be created
    timer.schedule(new RemindTask(), 6000, seconds * 1000); // delay
                                                    // in milliseconds
}

// this is an inner class...
class RemindTask extends TimerTask {

    @Override
    public void run() {

        // As the TimerTask run on a seprate thread from UI thread we have
        // to call runOnUiThread to do work on UI thread.
        runOnUiThread(new Runnable() {
            public void run() {

            myPager.setCurrentItem(myPager.getCurrentItem() + 1);

            }
        });

    }
}

 myPager.setOnPageChangeListener(new OnPageChangeListener() {

        @Override
        public void onPageSelected(int arg0) {
            Log.e("pageselectrd", "selected:" + String.valueOf(arg0));
            timer.cancel();
            pageSwitcher(5);
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {
        }

        @Override
        public void onPageScrollStateChanged(int arg0) {
        }
    });

屏幕上有多个ImageView
