butterknife使用，相当于findviewById

导入包

compile 'com.jakewharton:butterknife:7.0.1'

代码如下

@Bind(R.id.tab)TabLayout tabLayout;@Bind(R.id.viewpager)ViewPager viewPager;@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    ButterKnife.bind(this);    initData();    setAdapter();}
