Question

我是android app开发者的初学者，我见过很多使用@bind和@inject的开源应用程序，也默认@override

我想知道那些是什么，有什么不同。@ Inject LessonCatalogActivityPresenter lessonCatalogActivityPresenter;

@Inject
MarketService marketService;

@Inject
ShareService shareService;

@Bind(R.id.toolbar)
Toolbar toolbar;

@Bind(R.id.sliding_tabs)
TabLayout tabLayout;

@Bind(R.id.view_pager)
ViewPager viewPager;

@BindString(R.string.title_activity_lesson_catalog)
String title;

@Bind(R.id.fab)
FloatingActionButton floatingActionButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_lesson_catalog);
    ButterKnife.bind(this);
    initToolbar();
    initTabs();
    initTitle();
    lessonCatalogActivityPresenter.setView(this);
    lessonCatalogActivityPresenter.initialize();
}

private void initToolbar() {
    setSupportActionBar(toolbar);
}


private void initTabs() {
    viewPager.setAdapter(new LessonsPageAdapter(getFragmentManager()));
    viewPager.setOffscreenPageLimit(OFF_SCREEN_PAGE_LIMIT);
    tabLayout.setupWithViewPager(viewPager);
    viewPager.addOnPageChangeListener(this);
}

private void initTitle() {
    getSupportActionBar().setTitle(title);
}

@Override
public void injectActivity(ActivityComponent component) {
    component.inject(this);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;`

@Override注释表示此方法存在于其超类之一中，请参阅此javadoc
在您的示例中，ButterKnife使用@Bind注释将您的实例变量viewPager，tabLayout ..映射到各自的UI组件
我认为@Inject是Dagger用于在您的服务中应用依赖注入的var buff = new Buffer(_msg.content); _msg.content = AES.decrypt(clients.getKeyOf(_msg.clientID), '', buff).toString('utf8');但我们无法确定如何不查看顶部的导入类

@ bind，@ inject和@override
