我有一个使用抽屉导航的应用程序。在我的应用程序中，第一个 fragment (默认)包含谷歌地图和谷歌地图 api Activity 。我面临的问题是当我用另一个 fragment 替换默认 fragment 时它工作正常但是当我再次回到我的默认页面时应用程序崩溃并向我展示错误

android.view.InflateException:二进制 XML 文件第 6 行:膨胀类 fragment 时出错这是我的代码

public class MainActivity extends FragmentActivity {

        }
        fragmentManager = getFragmentManager();
        fragmentTransaction = fragmentManager.beginTransaction();
        HomeFragment homefragment = new HomeFragment();
        fragmentTransaction.add(R.id.mainContent, homefragment).commit();
        flag = true;
    }

                selectItemFromDrawer(position);
            }

Answer 1

你需要</android.support.v4.widget.DrawerLayout>在你的 activity_main.xml 的末尾
