动态刷新fragment的方法

//动态刷新fragment的方法

//将FragmentTransaction中的fragment全部清除
public void addFragment() {
	if(fragment_list != null){
		FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
		for(Fragment f: fragment_list){
			ft.remove(f);
		}
		ft.commitAllowingStateLoss();
		ft=null;
		getSupportFragmentManager().executePendingTransactions();
	}
	fragment_list.clear();
	Fragment1 f1=new Fragment1();
	f1.setOnJumpListener(new OnJumpListener() {
		
		@Override
		public void jumpToDetail() {
			// TODO Auto-generated method stub
			home_pager.setCurrentItem(1, true);
		}
	});
	fragment_list.add(f1);
	fragment_list.add(new Fragment2());
}

//刷新
adapter.notifyDataSetChanged();

//同样可以在adapter里面这边使用
public void setFragments(ArrayList<Fragment> fragments) {
	if(this.fragment_list != null){
		FragmentTransaction ft = fm.beginTransaction();
		for(Fragment f:this.fragment_list){
			ft.remove(f);
		}
		ft.commit();
		ft=null;
		fm.executePendingTransactions();
	}
	this.fragment_list = fragments;
	notifyDataSetChanged();
}
