Fragment 与Activity

一个Activity 对应 多个Fragment;

每一个类 extends Fragment ,

一个Activity 可以同时显示多个 Fragment;

Fragment是依赖于Activity的，而且生命周期也跟Activity绑定一起。

调用Activity:

Intent intent = new Intent(MainActivity.this, MainView.class); startActivity(intent);

Activity 调用xml 文件：

public class MainView extends Fragment { public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.wificonfig,container,false); } }

 调用Fragment:

getSupportFragmentManager().beginTransaction().replace(R.id.drawer_layout, new Robotview()).commit();Fragment 调用 xml layout： public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment return inflater.inflate(R.layout.fragment_robotview, container, false); }
