DrawerLayout 在supportV4 Lib中，類似開源slidemenu一樣，DrawerLayout父類為ViewGroup，自訂群組件基本都是擴充這個類。
android.support.v4.widget.DrawerLayout

下面是個簡單的用法示範。點左上方的按鈕 開啟抽屜菜單。

點擊對應的ITEM 切換對應的內容，內容顯示使用Fragment，這裡沒用到ActionBar來做切換<喎?http://www.bkjia.com/kf/ware/vc/" target="_blank" class="keylink">vcD4NCjxwcmUgY2xhc3M9"brush:java;"> <framelayout android:id="@+id/fragment_container" android:layout_height="match_parent" android:layout_width="match_parent"> </framelayout>

這裡唯寫HomeFragment代碼，其它幾個內容都是一樣的。

public class HomeFragment extends Fragment {    public HomeFragment() {    }    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container,            Bundle savedInstanceState) {        return inflater.inflate(R.layout.home_fg, container,false);    }    @Override    public void onViewCreated(View view, Bundle savedInstanceState) {        super.onViewCreated(view, savedInstanceState);        TextView textView = (TextView) view.findViewById(R.id.text);        textView.setText("Home");    }}
