The application’s PagerAdapter changed the adapter’s contents without calling PagerA

ATAL EXCEPTION: main java.lang.IllegalStateException: The application’s PagerAdapter changed the adapter’s contents without calling PagerAdapter#notifyDataSetChanged! 

出错原因：数据更新必须在main thread进行更新！！结束前还得调用 notifyDataSetChanged() ！！

我的具体做法即：

final MyPagerAdapter adpater = new MyPagerAdapter(getSupportFragmentManager());

final ViewPager viewFlipper = (ViewPager) findViewById(R.id.pager);

runOnUiThread(new Runnable() {//在主线程里面设置adpater

@Override

public void run() { 

// TODO Auto-generated method stub

viewFlipper.setAdapter(adpater);

}

});

adpater.notifyDataSetChanged();//然后再通知数据改变，与setAdapter（）一起放在runOnUiThread（）里面亦可
