Android 如何在 TabLayout 中以编程方式创建选项卡
How to create programmatically Tabs in TabLayout on Android
为什么没有人帮助我？
在我的应用程序中，我想在 tabLayout 中动态创建 tabs 并且我希望在从服务器 获取数据时 和此数据 count > 0 然后创建 tab.
对于 TabLayout，我使用这个库：https://github.com/egemenmede/etiyabadgetab
为了这个工作我写了下面的代码：
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>() {
@Override
public void onResponse(Call<FullSearchResponse> call, Response<FullSearchResponse> response) {
FullSearchResponse searchResponse = response.body();
if (searchResponse.getData().getMoviesCount() > 0) {
movieCount = searchResponse.getData().getMoviesCount();
movieList.clear();
movieList.addAll(searchResponse.getData().getMovies());
}
if (searchResponse.getData().getSeriesCount() > 0) {
serieCount = searchResponse.getData().getSeriesCount();
seriesList.clear();
seriesList.addAll(searchResponse.getData().getSeries());
}
if (searchResponse.getData().getEpisodesCount() > 0) {
episodesCount = searchResponse.getData().getEpisodesCount();
}
if (searchResponse.getData().getCelebritiesCount() > 0) {
celebritiesCount = searchResponse.getData().getCelebritiesCount();
celebrityList.clear();
celebrityList.addAll(searchResponse.getData().getCelebrities());
}
if (searchResponse.getData().getUsersCount() > 0) {
usersCount = searchResponse.getData().getUsersCount();

userList.addAll(searchResponse.getData().getUsers());
}
setupViewPager(fullSearch_ViewPager);
setupTabs();

if (tab == null) throw new IllegalArgumentException("Tab null olmamali.");
EtiyaBadgeTabBuilder builder = mTabBuilders.get(tab.getPosition());
