Android design包自定义tablayout的底部导航栏的实现方法

以前做项目大多用的radiobutton,今天用tablayout来做一个tab切换页面的的效果.

实现的效果就是类似QQ.微信的页面间(也就是Fragment间)的切换.如图:

布局只要一个tablayout

然后就是activity了

public class MainActivity extends baseActivity implements TabLayout.OnTabSelectedListener{
  @BindView(R.id.main_container)
  LinearLayout mainContainer;
  @BindView(R.id.nav_tl)
  TabLayout navTl;
  //Tab 文字
  private final int[] TAB_TITLES = new int[]{R.string.nav_home,R.string.nav_order,R.string.nav_my};
  //Tab 图片
  private final int[] TAB_IMGS = new int[]{R.drawable.nav_home_bg,R.drawable.nav_order_bg,R.drawable.nav_my_bg};
//贴出一个R.drawable.nav_home_bg的文件,其他类似:`

  private FirstPagerFragment firstPagerFragment;
  private PersonalFragment personalFragment;
  private SeekOrderFragment seekOrderFragment;
  private android.support.v4.app.FragmentManager manager;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);
    iniView();
    iniData();
  }
  private void iniData() {
  }
  private void iniView() {
    LayoutInflater inflater = LayoutInflater.from(this);
    manager = getSupportFragmentManager();
    getTab(R.id.main_container,manager,0);
    setTabs(navTl,inflater,TAB_TITLES,TAB_IMGS);
    navTl.setonTabSelectedListener(this);
  }
  
  private void setTabs(TabLayout tabLayout, LayoutInflater inflater, int[] tabTitlees, int[] tabImgs) {
    for (int i = 0; i < tabImgs.length; i++) {
      TabLayout.Tab tab = tabLayout.newTab();
      View view = inflater.inflate(R.layout.customer_layout, null);
      tab.setCustomView(view);
      TextView tvTitle = (TextView) view.findViewById(R.id.tv_tab);
      tvTitle.setText(tabTitlees[i]);
      ImageView imgTab = (ImageView) view.findViewById(R.id.img_tab);
      imgTab.setImageResource(tabImgs[i]);
      tabLayout.addTab(tab);
    }
  }
  @Override
  public void onTabSelected(TabLayout.Tab tab) {
    getTab(R.id.main_container,manager,tab.getPosition());
  }
  @Override
  public void onTabUnselected(TabLayout.Tab tab) {
  }
  @Override
  public void onTabReselected(TabLayout.Tab tab) {
  }
  //设置tab的监听,选中某一个tab对应的Fragment要及时切换,相信大家看代码能看明白
  private void getTab(int container, android.support.v4.app.FragmentManager manager, int position){
    FragmentTransaction ft = manager.beginTransaction();
    hideAll(ft);
    switch (position){
      case 0:
 if(firstPagerFragment==null){
   firstPagerFragment=new FirstPagerFragment();
   ft.add(container,firstPagerFragment);
 }else {
   ft.show(firstPagerFragment);
 }
 break;
      case 1:
 if(seekOrderFragment==null){
   seekOrderFragment=new SeekOrderFragment();
   ft.add(container,seekOrderFragment);
 }else {
   ft.show(seekOrderFragment);
 }
 break;
      case 2:
 if(personalFragment==null){
   personalFragment=new PersonalFragment();
   ft.add(container,personalFragment);
 }else {
   ft.show(personalFragment);
 }
 break;
    }
    ft.commit();
  }
  private void hideAll(FragmentTransaction ft) {
    if(firstPagerFragment!=null){
      ft.hide(firstPagerFragment);
    }
    if(personalFragment!=null){
      ft.hide(personalFragment);
    }
    if(seekOrderFragment!=null){
      ft.hide(seekOrderFragment);
    }
  }
}
