android bundle的判断

通过bundle传递参数的时候，在新的页面接收参数，可以通过

发送页面传递参数：

Bundle todetailBundle = new Bundle();
     todetailBundle.putString("inter_id", inter_id);
     WeihuEditDetail weihuEditDetail = new WeihuEditDetail();
     FragmentManager fm1 = getFragmentManager();
     FragmentTransaction ft1 = fm1.beginTransaction();
     weihuEditDetail.setArguments(todetailBundle);   
     ft1.replace(R.id.frag_container_linearyout,
       weihuEditDetail, "weihueditdetail");

     ft1.commit();

接收方判断bundle是否含有所传的值，如果有值对值进行读取和赋值操作：

private String  inter_id_tobeedit;

if(bundle!=null&&bundle.containsKey("inter_id")){
   inter_id_tobeedit = bundle.getString("inter_id");
  }
