Activity 跳转到 Fragment



主要学习了activity跳转到fragment：

例如：

--------到----》

财富页面 属于一级页面，收货地址--->管理 属于二级页面

现需求从二级页面即DesActivity 跳转到 三级页面 

代码如下：

DescActivity.java

Public class DescActivity extends FragmentActitvity{

   public void onCreate(Bundle saveInstance){

      super.onCreate(saveInstanceState);

      fm=getFragmentManager();//初始化Fragment对象

      setContentView(R.layout.activity_two);//加载二级页面

      des_framelayout=(FrameLayout)findViewById(R.id.des_framelayout);//获取activity_two的framelayout

      Intent intent=getIntent();//获取Intent传来的数据

      String ex=intent.getStringExtra("key");//设置“标志值”

      Utils.showToast(getApplicationContext(),ex);//????

      switch(ex){

          case "GoodsFragment":

             if(null==goodsTwoFragment){

                 goodsTwoFragment=new GoodsTwoFragment();

             }

             ft=getSupportFragmentMannager().beginTransaction();

             ft.replace(R.id.des_framelayout,goodsTwoFragment,"GoodTwo");

             ft.commit();

             break;

              ……

           case "wealth_address":

             if(null==wealthAddfragment){

                 wealthAddFragment=new WealthAddFragment();

             }

             ft=getSupportFragmentManager().beginTransaction();

             ft.replace(R.id.des_framelayout,wealthAddFragment,"wealthFragment");

             ft.commit();

             break;

      }

   }

}

代码如下：

WealthFragment.java

public class WealthFragment extends Fragment{

    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState){

       view=inflater.inflate(R.layout.frag_wealth,container,false);

       address();

       return view();

    }

    private void address(){

      wealth_address=(RelativeLayout)view.findViewById(R.id.wealth_address);

      wealth_address.setOnClickListener(new View.OnClickListener()){

         public void onClick(View v){

            Intent intent=new Intent(getContext(),DesActivity.class);

            intent.putExtra("key","wealth_address");

            startActivity(intent);

         }

     });

   }

}

代码如下：

WealthAddFragment.java

public class WealthAddFragment extends Fragment{

    public View onCreate(LayoutInflater inflater,ViewGroup container,Bundle saveInstanceState){

      view=view.inflate(getActivity(),R.layout.item_addressmanager,null);

     

}

}
