Question

为什么没有人帮助我？

在我的应用程序中，我希望在tabs中创建动态 tabLayout，我希望从服务器获取数据并且此数据计数＆GT; 0 然后创建tab 对于TabLayout，我使用此库：https://github.com/egemenmede/etiyabadgetab

对于这项工作，我写下以下代码：

public class FullSearch extends AppCompatActivity {

    @BindView(R.id.fullSearch_tabLayout)
    BadgeTabLayout fullSearch_tabLayout;
    @BindView(R.id.fullSearch_ViewPager)
    ViewPager fullSearch_ViewPager;
    @BindView(R.id.toolbarTitleTxt)
    TextView toolbarTitleTxt;
    @BindView(R.id.fullSearch_LoadLay)
    RelativeLayout fullSearch_LoadLay;
    @BindView(R.id.fullSearch_ReloadLay)
    RelativeLayout fullSearch_ReloadLay;
    @BindView(R.id.fullSearch_NoNet)
    RelativeLayout fullSearch_NoNet;
    private Context context;
    private Bundle bundle;
    private String fullSearchText;
    private final String[] tabsName = {"Movies", "Series", "Episodes", "Celebrities", "Users"};
    private List<Movie> movieList = new ArrayList<>();
    private List<Series> seriesList = new ArrayList<>();
    private List<Celebrity> celebrityList = new ArrayList<>();
    private List<User> userList = new ArrayList<>();
    private int movieCount, serieCount, episodesCount, celebritiesCount, usersCount;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_full_search);

        // Initialize
        ButterKnife.bind(this);
        context = this;
        bundle = getIntent().getExtras();
        fullSearchText = bundle.getString(ExtraContains.FULL_SEARCH_TEXT.name());

        toolbarTitleTxt.setText(fullSearchText);

        // set viewPager to tabLayout
        fullSearch_tabLayout.setupWithViewPager(fullSearch_ViewPager);

        // customize tab layout
        fullSearch_tabLayout.setSelectedTabIndicatorColor(context.getResources().getColor(R.color.colorAccent));
        fullSearch_tabLayout.setSelectedTabIndicatorHeight(5);
        fullSearch_tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
        fullSearch_tabLayout.setTabGravity(TabLayout.GRAVITY_CENTER);

        fullSearch_LoadLay.setVisibility(View.GONE);

        getData();
    }

    @Override
    protected void onResume() {
        super.onResume();
        //checkNet();
        //fullSearch_LoadLay.setVisibility(View.GONE);
    }

    private void getData() {
        FullSearchSendData sendData = new FullSearchSendData();
        sendData.setKey(fullSearchText);
        sendData.setLoadImages(true);
        sendData.setSearchInCelebrities(true);
        sendData.setSearchInMovies(true);
        sendData.setSearchInSeries(true);
        sendData.setSearchInEpisodes(true);
        sendData.setSearchInUsers(true);
        sendData.setPageIndex(1);
        sendData.setPageSize(10);
        sendData.setMaxDistance(1);

        fullSearch_LoadLay.setVisibility(View.VISIBLE);

        InterfaceApi api = ApiClient.getClient().create(InterfaceApi.class);
        Call<FullSearchResponse> call = api.getFullSearch(sendData);

        call.enqueue(new Callback<FullSearchResponse>() {

单击错误消息中的第一个链接时，请转到以下代码：

public EtiyaBadgeTabBuilder selectEtiyaBadgeTab(int position) {
    Tab tab = getTabAt(position);

    if (tab == null) throw new IllegalArgumentException("Tab null olmamali.");

    EtiyaBadgeTabBuilder builder = mTabBuilders.get(tab.getPosition());
    if (builder == null) {
        builder = new EtiyaBadgeTabBuilder(this, tab);
        mTabBuilders.put(tab.getPosition(), builder);
    }

    return builder;

如何解决此问题并在tabs中创建动态 tabLayout？

请帮助我，我真的需要你的帮助。谢谢所有＆lt; 3

试试这个。

 private void setupTabs() {
        if (movieCount > 0) {
            fullSearch_tabLayout.addTab(fullSearch_tabLayout.newTab());
            fullSearch_tabLayout.selectEtiyaBadgeTab(fullSearch_tabLayout.getTabCount()-1)
                    .tabTitle("Movies")

            fullSearch_tabLayout.selectEtiyaBadgeTab(fullSearch_tabLayout.getTabCount()-1)
                    .tabTitle("Celebrities")
                    .tabTitleColor(R.color.white)
                    .tabBadge(true)
                    .tabBadgeCount(celebritiesCount)
                    .tabBadgeCountMore(false)
                    .tabBadgeBgColor(R.color.colorAccent)

        if (usersCount > 0) {
          fullSearch_tabLayout.addTab(fullSearch_tabLayout.newTab());
            fullSearch_tabLayout.selectEtiyaBadgeTab(fullSearch_tabLayout.getTabCount()-1)
                    .tabTitle("Users")
                    .tabTitleColor(R.color.white)
                    .tabBadge(true)
                    .tabBadgeCount(usersCount)

                    .createEtiyaBadgeTab();
        }
    }

和我的测试代码：

   EtiyaBadgeTab tab = (EtiyaBadgeTab) findViewById(R.id.tabbadgelayout);
    tab.addTab(tab.newTab());
    tab.addTab(tab.newTab());
    tab.addTab(tab.newTab());
    tab.selectEtiyaBadgeTab(0)
            .tabTitle("11111")
            .tabBadge(true)
            .tabBadgeCount(22)
            .tabBadgeCountMore(false)
            .tabBadgeCornerRadius(15)
            .createEtiyaBadgeTab();

    tab.selectEtiyaBadgeTab(1)
            .tabTitle("22222")
            .tabBadge(true)
            .tabBadgeCount(22)
            .tabBadgeCountMore(false)
            .tabBadgeCornerRadius(15)
            .createEtiyaBadgeTab();
    tab.selectEtiyaBadgeTab(2)
            .tabTitle("33333")
            .tabBadge(true)
            .tabBadgeCount(22)
            .tabBadgeCountMore(false)
            .tabBadgeCornerRadius(15)
            .createEtiyaBadgeTab();
