Android - 构造函数 ActionBarDrawerToggle 未定义

Question

我在我的 oncreate 函数中使用了这段代码，通过按应用程序图标打开抽屉导航。

ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                (DrawerLayout) findViewById(R.id.left_drawer), /* DrawerLayout object */
                getResources().getDrawable(R.drawable.ic_drawer),  /* nav drawer icon to replace 'Up' caret */
                getString(R.string.drawer_open),  /* "open drawer" description */
                getString(R.string.drawer_close)  /* "close drawer" description */
                ) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                getActionBar().setTitle(R.string.title_activity_add);
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                getActionBar().setTitle(R.string.drawer_title);
            }
        };

现在它说“构造函数 ActionBarDrawerToggle(AddActivity, DrawerLayout, Drawable, String, String) 未定义”。我已经导入了 android.support.v4.app.ActionBarDrawerToggle。问题出在哪里？

构造函数不是ActionBarDrawerToggle(AddActivity, DrawerLayout, Drawable, String, String)。它是 ActionBarDrawerToggle(Activity, DrawerLayout, int, int, int)。将最后三个参数更改为资源 ID，而不是引用资源 ID 的结果。
