创建时受保护的void(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager=(viewPager)findViewById(R.id.viewPager);
设置viewPager(viewPager);
tabLayout=(tabLayout)findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
TextView tabOne=(TextView)LayoutInflater.from(this).flate(R.layout.custom_tab,null);
tabOne.setText(“一”);
tabOne.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.ic_tab_调用,0,0);
tabLayout.getTabAt(0.setCustomView(tabOne);
TextView tabTwo=(TextView)LayoutInflater.from(this).flate(R.layout.custom_tab,null);
tabTwo.setText(“两个”);
tabTwo.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.iconos,0,0);
tabLayout.getTabAt(1).setCustomView(tabTwo);
}
专用无效设置ViewPager(ViewPager ViewPager){
ViewPagerAdapter适配器=新的ViewPagerAdapter(getSupportFragmentManager());
addFrag(新的OneFragment(),“”);
addFrag(新的TwoFragment(),“”);
addFrag(新的ThreeFragment(),“”);
viewPager.setAdapter(适配器);
}
类ViewPagerAdapter扩展了FragmentPagerAdapter{
私有最终列表MFFragmentList=new ArrayList();
私有最终列表MFFragmentTitleList=new ArrayList();
公共视图页面编辑器(碎片管理器){
高级经理;
}
@凌驾
公共片段getItem(int位置){
返回MFFragmentList.get(位置);
}
@凌驾
public int getCount(){
返回MFFragmentList.size();
}
public void addFrag(片段、字符串标题){
添加(片段);
MFFragmentTitleList.add(标题);
}
@凌驾
公共字符序列getPageTitle(int位置){
返回MFFragmentTitleList.get(位置);
}
}
有什么想法吗?
谢谢。我的表格布局在线性布局内,如下图所示,给出了线性布局的“底部”tp重力,这就是我在课堂上使用它的方式
