android BaseFragment 工具类

一、定义
/**
 * @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();
    }

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return initView();
}


    @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

   /**
 * @类名    LeftMenuFragment
 * @创建者   ppa
 * @创建时间 2016-3-21
 * @描述   TODO
 */
public class ContentFragment extends BaseFragment {


@Override
public View initView() {
View view=View.inflate(mActivity,R.layout.fragment_content, null);
return view;
}


@Override
public void initData() {
// TODO Auto-generated method stub
}


}

三、使用（import android.support.v4.app.FragmentManager;）

    FragmentManager fm = getSupportFragmentManager();
FragmentTransaction bt = fm.beginTransaction();
bt.replace(R.id.fl_content,new ContentFragment());
bt.replace(R.id.fl_left_menu,new LeftMenuFragment());
bt.commit();
