在我的应用程序中,我想在tabLayout
中动态创建tabs
,我想当从服务器获得数据时,该数据计数〉0**,然后创建tab
。
对于TabLayout,我使用以下库:https://github.com/egemenmede/etiyabadgetab
对于此工作,我编写以下代码:
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().getCelebritiesCount() > 0) {
celebritiesCount = searchResponse.getData().getCelebritiesCount();
celebrityList.clear();
celebrityList.addAll(searchResponse.getData().getCelebrities());
}
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().getUsersCount() > 0) {
usersCount = searchResponse.getData().getUsersCount();
userList.clear();
userList.addAll(searchResponse.getData().getUsers());
}
setupViewPager(fullSearch_ViewPager);
setupTabs();
fullSearch_LoadLay.setVisibility(View.GONE);
//fullSearch_Swipe.setRefreshing(false);
}
@Override
public void onFailure(Call<FullSearchResponse> call, Throwable t) {
fullSearch_LoadLay.setVisibility(View.GONE);
fullSearch_ReloadLay.setVisibility(View.VISIBLE);
}
});
}
private void setupTabs() {
if (celebritiesCount > 0) {
fullSearch_tabLayout.addTab(new TabLayout(context).newTab());
fullSearch_tabLayout.selectEtiyaBadgeTab(0)
.tabTitle("Celebrities")
.tabTitleColor(R.color.white)
.tabBadge(true)
.tabBadgeCount(celebritiesCount)
.tabBadgeCountMore(false)
.tabBadgeBgColor(R.color.colorAccent)
.tabBadgeTextColor(R.color.white)
.tabBadgeStroke(2, R.color.white)
.tabBadgeCornerRadius(15)
.createEtiyaBadgeTab();
}
if (movieCount > 0) {
fullSearch_tabLayout.addTab(new TabLayout(context).newTab());
fullSearch_tabLayout.selectEtiyaBadgeTab(1)
.tabTitle("Movies")
.tabTitleColor(R.color.white)
.tabBadge(true)
.tabBadgeCount(movieCount)
.tabBadgeCountMore(false)
.tabBadgeBgColor(R.color.colorAccent)
.tabBadgeTextColor(R.color.white)
.tabBadgeStroke(2, R.color.white)
.tabBadgeCornerRadius(15)
.createEtiyaBadgeTab();
}
if (serieCount > 0) {
fullSearch_tabLayout.addTab(new TabLayout(context).newTab());
fullSearch_tabLayout.selectEtiyaBadgeTab(2)
.tabTitle("Series")
.tabTitleColor(R.color.white)
.tabBadge(true)
.tabBadgeCount(serieCount)
.tabBadgeCountMore(false)
.tabBadgeBgColor(R.color.colorAccent)
.tabBadgeTextColor(R.color.white)
.tabBadgeStroke(2, R.color.white)
.tabBadgeCornerRadius(15)
.createEtiyaBadgeTab();
}
if (usersCount > 0) {
fullSearch_tabLayout.addTab(new TabLayout(context).newTab());
fullSearch_tabLayout.selectEtiyaBadgeTab(3)
.tabTitle("Users")
.tabTitleColor(R.color.white)
.tabBadge(true)
.tabBadgeCount(usersCount)
.tabBadgeCountMore(false)
.tabBadgeBgColor(R.color.colorAccent)
.tabBadgeTextColor(R.color.white)
.tabBadgeStroke(2, R.color.white)
.tabBadgeCornerRadius(15)
.createEtiyaBadgeTab();
}
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
if (celebritiesCount > 0) {
adapter.addFrag(FullSearchCelebritiesFragment.getInstance(celebrityList, celebritiesCount, fullSearchText), "Celebrities");
}
if (movieCount > 0) {
adapter.addFrag(FullSearchMovieFragment.getInstance(movieList, movieCount, fullSearchText), "Movies");
}
if (serieCount > 0) {
adapter.addFrag(FullSearchSeriesFragment.getInstance(seriesList, serieCount, fullSearchText), "Series");
}
if (usersCount > 0) {
adapter.addFrag(FullSearchUsersFragment.getInstance(userList, usersCount, fullSearchText), "Users");
}
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
但在运行应用程序时显示此错误:

java.lang.IllegalArgumentException: Tab belongs to a different TabLayout.

单击错误消息中的第一个链接时,转到此代码:
fullSearch_tabLayout.addTab(new TabLayout(context).newTab());
如何修复此问题并在tabLayout
中动态创建tabs
?
请帮助我,我真的需要你的帮助。谢谢所有〈3

在TabLayout示例上调用newTab()函数。
new
关键字是问题所在,因为您正在为每个新标签创建TabLayout的新示例,并试图将其添加到现有示例中。
