android 代码生成fragment,Android开发笔记——侧滑Menu+Fragment框架代码(有些代码为AS自动生成) ... .....

3.MainActivity 布局代码：VS 生成

android:id="@+id/drawer_layout"

android:layout_width="match_parent"

android:layout_height="match_parent"

tools:context=".MainActivity">

android:id="@+id/container"

android:layout_width="match_parent"

android:layout_height="match_parent" />

5.FragmentMenu1 测试代码：public class FragmentMenu1 extends Fragment {

public static FragmentMenu1 newInstance() {

return new FragmentMenu1();

}

@Override

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

View rootView = inflater.inflate(R.layout.fragment_menu1, container, false);

return rootView;

}

}
