Android drawerlayout Drawer

Drawerlayout in SupportV4 Lib, like the open source Slidemenu, the Drawerlayout parent class is ViewGroup, and the custom component basically extends the class.
Android.support.v4.widget.DrawerLayout

The following is a simple usage demonstration. Click the button on the top left corner to open the drawer menu.

Click on the corresponding item to toggle the corresponding content, the content is displayed using fragment, here is useless to Actionbar to do the switch

There is only homefragment code written here, and several other things are the same.

 Public  class homefragment extends Fragment {     Public homefragment() {    }@Override     PublicViewOncreateview(Layoutinflater inflater, ViewGroup container, Bundle savedinstancestate) {returnInflater.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"); }}
