Android导航抽屉BaseActivity示例

Question

Can someone suggest me a tutorial how to create a BaseActivity for the Android Navigation Drawer ?

Or can anyone post a sample BaseActivity for the Navigation Drawer including the layout ?

Answer 2

Download sample Code from Google ni have edited that code as basic navigation drawer with fragment no imageview

public class MainActivity extends Activity {

    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;
    private ActionBarDrawerToggle mDrawerToggle;

    private CharSequence mDrawerTitle;
    private CharSequence mTitle;
    private String[] mPlanetTitles;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.navigation_drawer);

        Fragment fragment = new PlanetFragment();
        FragmentManager fragmentManager = getFragmentManager();
        fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();

     //   mTitle = mDrawerTitle = getTitle();
      //  mPlanetTitles = getResources().getStringArray(R.array.planets_array);
       // mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        //mDrawerList = (ListView) findViewById(R.id.right_drawer);

        // set a custom shadow that overlays the main content when the drawer opens
       // mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
   /*     // set up the drawer's list view with items and click listener
       // mDrawerList.setAdapter(new ArrayAdapter<String>(this,
                R.layout.drawer_list_item, mPlanetTitles));
        mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

        // enable ActionBar app icon to behave as action to toggle nav drawer
      //  getActionBar().setDisplayHomeAsUpEnabled(true);
       // getActionBar().setHomeButtonEnabled(true);

        // ActionBarDrawerToggle ties together the the proper interactions
        // between the sliding drawer and the action bar app icon
        mDrawerToggle = new ActionBarDrawerToggle(
                this,                   host Activity
