Fragement的使用

1. 创建class继承自Fragement，实现Fragement的三个方法

public abstract class BaseFragement extends Fragment {
    public Activity activity;

    //fragement创建
    @Override
    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        activity = getActivity();
    }
    //创建Fragement布局
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        return initview();
    }
    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onActivityCreated(savedInstanceState);
        initdate();
    }
    public abstract View initview();
    public void initdate(){

    }
}

2.创建Class继承自BaseFragement

public class ContentFragment extends BaseFragement {

    @Override
    public View initview() {
        View view = View.inflate(activity, R.layout.content_frament, null);
        return view;
    }

}

3.通过开启事务，填充Fragement

FragmentManager manager = getSupportFragmentManager();
        FragmentTransaction transaction = manager.beginTransaction();
        transaction.replace(R.id.fl_content, new ContentFragment());
        transaction.replace(R.id.fl_left, new LeftmenuFragement());
        transaction.commit();
