java.lang.IllegalStateException: Recursive entry to executePendingTransactions

在Fragment里面添加Viewpager，Viewpager由多个Fragment组成

java.lang.IllegalStateException: Recursive entry to executePendingTransactions

找到发送错误的地方是viewpager.setAdapter()处。

我的应用场景是： 嵌套使用Fragment使用，最外层使用了一个第三方的库，里面使用FragmentActivity，每个Fragment中又使用ViewPager再嵌套Fragment

解决方法：嵌套Fragment设置PageAdapter时要使用getChildFragmentManager。

New version of Support Library v4 (or Android 4.2, ofcourse) resolve this problem much simply. For do this, simply do constructor of your custom FragmentPagerAdapter like this:

public CustomFragmentPagerAdapter(android.support.v4.app.Fragment fragment){    super(fragment.getChildFragmentManager());    // write your code here}

This work because new Android version approve using nested Fragments

我这里没有修改CustomFragmentPagerAdapter，而是新建CustomFragmentPagerAdapter对象时使用参数改为this.getChildFragmentManager();

adapter = new TabPageIndicatorAdapter(this.getChildFragmentManager()); 

TabPageIndicatorAdapter类内容不变：
 /** * ViewPager * @author liwenjin * */    class TabPageIndicatorAdapter extends FragmentPagerAdapter {           public TabPageIndicatorAdapter(FragmentManager  fm) {            super(fm);                    }        @Override        public Fragment getItem(int position) {            Fragment fragment = new ItemFragment();              Bundle args = new Bundle();              args.putString("arg", TITLE[position]);              fragment.setArguments(args);              return fragment;        }        @Override        public CharSequence getPageTitle(int position) {            return TITLE[position % TITLE.length];        }        @Override        public int getCount() {            return TITLE.length;        }    }


在查找资料是看到网上，这里先记下解决方案：
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
adapter = new MainFragmentPagerAdapter(getFragmentManager(), fragments);
viewPager.setAdapter(adapter); 
switchPager(0);
}
}, 100);
