android 抽取BaseFragment

一、抽取 BaseFragment

**

* @类名 BaseFragment

* @创建者 ppa

* @创建时间 2016-3-21

* @描述 TODO

*/

public abstract class BaseFragment extends Fragment {

public Activity mActivity;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

mActivity = getActivity();
//通过fragment的Activity实例化mActivity

}

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

return initView();
//通过继承者重载initView实例化view

}

@Override

public void onActivityCreated(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onActivityCreated(savedInstanceState);

initData();

}

public abstract View initView();

public abstract void initData();

}

二、继承 BaseFragment类

/**

* @类名 LeftMenuFragment

* @创建者 ppa

* @创建时间 2016-3-21

* @描述 TODO

*/

public class LeftMenuFragment extends BaseFragment {

private ListView lvLeftMemu;

private NewsData mNewsData;

private ArrayList<NewsMenuData> myMenulist;

private int mCurrentPos;

private myMenuAdapter myMenuAdapter;

@Override

public View initView() {

View view=View.inflate(mActivity,R.layout.fragment_left_menu, null);

lvLeftMemu=(ListView) view.findViewById(R.id.lv_left_menu);

return view;

}

@Override

public void initData() {

}

/**

* 获取到contentFragment中展示NewsPager

* @param position

*/

protected void setMenuCurrentPager(int position) {

Main2Activity activity = (Main2Activity) mActivity; //获取Activity

ContentFragment contentFragment = activity.getContentFragment();

NewsPager newsPager = contentFragment.getNewsPager();

newsPager.setCurrentMenuDetailPager(position);

}

}
