如何在導航抽屜中使用OnItemClickListener？

Question

我的App中有一個Navigation Drawer中有項目，但是我不知道如何從每個項目中打開新的Activity。

我已經嘗試了一些方法並對其進行了評論...

謝謝你的幫助 ...

主要活動

public class MainActivity extends ActionBarActivity
{
    private ListView mDrawerList;
    protected DrawerLayout mDrawer;
    private CustomActionBarDrawerToggle mDrawerToggle;
    private String[] menuItems;

    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // getSupportActionBar().hide();
        setContentView(R.layout.activity_main_drawer);

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

        mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);

        // set a custom shadow that overlays the main content when the drawer
        // opens
        mDrawer.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);

        _initMenu();
        mDrawerToggle = new CustomActionBarDrawerToggle(this, mDrawer);
        mDrawer.setDrawerListener(mDrawerToggle);
        // if (savedInstanceState == null)
        // {
        // selectItem(0);
        // }

    }

    private void _initMenu()

        NsMenuAdapter mAdapter = new NsMenuAdapter(this);

        // Add Header
        mAdapter.addHeader(R.string.ns_menu_main_header);

        // Add first block

        menuItems = getResources().getStringArray(R.array.ns_menu_items);

            // Highlight the selected item, update the title, and close the
            // drawer

            // Toast.makeText(MainActivity.this, text,
            // Toast.LENGTH_LONG).show();
            // // You should reset item counter
            //mDrawer.closeDrawer(mDrawerList);
            Intent intent = new Intent(MainActivity.this, Tutorial.class);
            startActivity(intent);

        }
    }

}

注意
我需要它來處理活動，而不是用於Fragments。

Answer 1

如果你希望你的NavigationDrawer在所有的活動，你可以從NavigationDrawer推出來處理，最好的辦法就是不推出新的Activity ，但更換Fragment 。

因為如果每次啟動新的Activity時，都需要在所有子Activity中實現NavigationDrawer 。 （不過很容易繼承）。

這里有一個不錯的教程，可以通過NavigationDrawer來“替換”片段：
