导航抽屉不显示在主页中

Question

我正在使用棒棒糖（api 21 级）。我已经实现了导航我 application.Everything 的抽屉正好是 fine.But 我没看到输出末尾的导航抽屉。
我在 runtime.My 没有收到任何错误，唯一的问题是，我不知道为什么我最后没有得到导航抽屉
下面贴出相关代码。

ChapterActivity.java:

public class ChapterActivity extends ActionBarActivity implements OnItemClickListener {

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

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

        mTitle = mDrawerTitle = getTitle();
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                R.drawable.ic_drawer,
                R.string.app_name, 

                R.string.app_name 
        ) {
            public void onDrawerClosed(View view) {
                setTitle(mTitle);
                // calling onPrepareOptionsMenu() to show action bar icons
                invalidateOptionsMenu();
            }

            public void onDrawerOpened(View drawerView) {
                setTitle(mDrawerTitle);
                // calling onPrepareOptionsMenu() to hide action bar icons
                invalidateOptionsMenu();
            }
        };  

        mDrawerLayout.setDrawerListener(mDrawerToggle);
        initialize();
        listChapter.setOnItemClickListener(this);
        mDrawerList.setOnItemClickListener(this);
    }

     private void initialize() {

     actionBar();

     public void actionBar() {

                .parseColor("#FFFFFF")));

        actionBar.setDisplayShowTitleEnabled(false);

        actionBar.setCustomView(mCustomView);
        actionBar.setDisplayShowCustomEnabled(true);

            listChapter.setAdapter(ac); 
            mDrawerList.setAdapter(ac);

终于没看到家里的导航抽屉page.Anyone可以帮我this.Where我有wrong.Thank你

Answer 1

您似乎在使用 android.support.v4.app.ActionBarDrawerToggle 。 class 已弃用，您应该使用 android.support.v7.app.ActionBarDrawerToggle，它也有不同的 constructor.

public ActionBarDrawerToggle (Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)
public ActionBarDrawerToggle (Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

第一个联系你实际行动吧。您只需要删除对 ic_launcher 的引用，并在导入中将 v4.app.ActionBarDrawerToggle 切换为 v7.app.ActionBarDrawerToggle。

第二个与 Toolbar 视图有关，我认为您没有实现。

我看到的第二个问题是覆盖 onDrawerOpened() 和 onDrawerClosed() 方法时缺少调用。你应该总是调用 super class:

        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
            // other stuff
        }

onDrawerOpened()也是如此。
