实现滑动效果的控件 使用：可以添加多个Fragment 适配器：viewPagerAdapter 作用：可以添加Fragment和TabLayout 用法： 自定义类继承viewPagerAdapter 重写四个方法 构造（调用父类构造） getItem（int i）{Fragment集合 .get（i）} getcount（）{Fragment集合.size（）} getpageTitle（int i）{title集合.get(i)} TabLayout：实现选项卡效果，配合viewPager搭配使用 用法： 导依赖 加标签 设置常用属性 tableColor:设置文字颜色； tabSelectTextColor：设置选中时的颜色 tabIndicatorColor：设置横线颜色 tabIndicatorHeight：设置横线高度 tabMode=“scrollable” 支持翻页
写Fragment
// An highlighted block public class Fragment3 extends Fragment { @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { return inflater.inflate(R.layout.view3,container,false); } }主类
// An highlighted block ArrayList<Fragment> fragments =new ArrayList<>(); Fragment1 fragment1=new Fragment1(); Fragment2 fragment2=new Fragment2(); Fragment3 fragment3=new Fragment3(); Fragment4 fragment4=new Fragment4(); Fragment5 fragment5=new Fragment5(); fragments.add(fragment1); fragments.add(fragment2); fragments.add(fragment3); fragments.add(fragment4); fragments.add(fragment5); MyAdapter myAdapter=new MyAdapter(getSupportFragmentManager(),fragments); viewPager.setAdapter(myAdapter);适配器
// An highlighted block public class MyAdapter extends FragmentPagerAdapter { ArrayList<Fragment> fragments; public MyAdapter(FragmentManager fm, ArrayList<Fragment> fragments) { super(fm); this.fragments=fragments; }同时添加Fragment和Tablayout的适配器
// An highlighted block public class MyAdapter2 extends FragmentPagerAdapter { ArrayList<Fragment> fragments; ArrayList<String> title; public MyAdapter2(FragmentManager fm, ArrayList<Fragment> fragments, ArrayList<String> title) { super(fm); this.fragments=fragments; this.title=title; } @Override public Fragment getItem(int i) { return fragments.get(i); } @Override public int getCount() { return fragments.size(); } @Nullable @Override public CharSequence getPageTitle(int position) { return title.get(position); } }
