我在AbstractActivity.class中创建了一个导航抽屉，我想在我的所有活动中使用该抽屉，所以我创建了另一个抽屉类并在另一个活动中扩展该类但它不起作用，任何人都可以告诉我什么是错的我的代码？

我正在扩展NavigationActivity类
的类public class Welcome extends NavigationActivity implements View.OnClickListener{
private CardView mAstro,mMatch,mPanch,mAsk,mContact;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getLayoutInflater().inflate(R.layout.activity_welcome,mFrameLayout_ContentFrame);
答案 0 :(得分：0)
这是一个相当常见的问题，一直在博客上发表。实际上，您希望使用包含导航抽屉的布局创建BaseActivity，然后让其他活动扩展BaseActivity并在BaseActivity的布局中扩展其布局。这样您就可以在所有活动中使用导航抽屉，并重复使用代码来设置抽屉（因为该代码位于BaseActivity中）。
您可以在此处找到示例实现以及更详细的说明：http://lucas-dev.com/blog/entry/base-activities-sliding-menu.html
