Хорошо, у меня есть Json, я хочу проанализировать его на вкладках (если у меня 6 строк, значит, 6 вкладок), я получаю данные, но не могу их проанализировать ..
кто-нибудь может помочь ???
public class WallpaperPageActivity extends BaseActivity {
private ViewPager mViewPager;
private TabLayout mTabLayout;
private WallpaperActivityFragmentAdapter wallpaperActivityFragmentAdapter;
private CategoryList resultCategories;
private ArrayList<Category> categoriesTab = new ArrayList<>();
protected ApiInterface service;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_wallpaper);
service = RestApiClient.getClient();
mViewPager = (ViewPager) findViewById(R.id.activity_wallpapers_content_viewpager);
mTabLayout = (TabLayout) findViewById(R.id.activity_wallpapers_content_tablayout);
getCategoryNames();
mViewPager.setAdapter(new WallpaperActivityFragmentAdapter(getSupportFragmentManager(), this, categoriesTab));
mViewPager.getAdapter().notifyDataSetChanged();
setTablayoutItemsMode(mTabLayout, categoriesTab);
mTabLayout.setupWithViewPager(mViewPager);
setupTabLayout(mTabLayout, categoriesTab);
}
public void getCategoryNames() {
Call<CategoryList> call = service.requestCategoryList("get_categories_wallpaper");
call.enqueue(new Callback<CategoryList>() {
@Override
public void onResponse(Response<CategoryList> response) {
Log.d("wow", "Status Code = " + response.code());
if (response.isSuccess()) {
// request successful (status code 200, 201)
resultCategories = response.body();
for (int i = 0; i < resultCategories.getCategories().size(); i++) {
categoriesTab.add(resultCategories.getCategories().get(i));
}
} else {
Log.d("wow", "error = ");
}
}
@Override
public void onFailure(Throwable t) {
}
});
}
public void setTablayoutItemsMode(TabLayout tabLayout, List<Category> categories) {
if (categories.size() > 3)
tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
else {
tabLayout.setTabMode(TabLayout.MODE_FIXED);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
}
}
}
это адаптер фрагмента.
public class WallpaperActivityFragmentAdapter extends FragmentPagerAdapter {
private int PAGE_COUNT = 1;
private ArrayList<Category> categoriesTab;
private Context context;
private Bundle bundle;
private WallpaperActivityFragment fragment;
public WallpaperActivityFragmentAdapter(FragmentManager fm, Context context, ArrayList<Category> categoriesTab) {
super(fm);
this.context = context;
this.categoriesTab = categoriesTab;
PAGE_COUNT = categoriesTab.size();
}
@Override
public int getCount() {
return PAGE_COUNT;
}
@Override
public Fragment getItem(int position) {
fragment = new WallpaperActivityFragment();
bundle = new Bundle();
bundle.putInt("position", position);
fragment.setArguments(bundle);
return fragment;
}
@Override
public CharSequence getPageTitle(int position) {
return categoriesTab.get(position).getCategoryName();
}
@Override
public int getItemPosition(Object object) {
return super.getItemPosition(object);
}
}
а это фрагмент
public class WallpaperActivityFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.wallpaper_content_fragment,container,false);
}
}
и это xml, который содержит viewpager и tablayout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/tablayout_linear"
android:orientation="horizontal" >
<include layout="@layout/category_btn"/>
<android.support.design.widget.TabLayout
android:id="@+id/activity_wallpapers_content_tablayout"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#FFFFFF"
app:tabGravity="fill"
app:tabMaxWidth="0dp"
app:tabMode="fixed" />
</LinearLayout>
<android.support.v4.view.ViewPager
android:id="@+id/activity_wallpapers_content_viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:layout_below="@+id/tablayout_linear"
android:background="#FFF123" />
Я уже включил его в файл activity_wallpaper ............ Теперь я не могу получить данные с помощью модернизации, но как это сделать (setTabText что-то вроде этого)
конечно, это в BaseActivity
public void setupTabLayout(TabLayout tabLayout, ArrayList<Category> categoriesTab) {
for (int i = 0; i < tabLayout.getTabCount(); i++) {
RelativeLayout customTab = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.page_content_custom_tab, null);
TextView tabTitle = (TextView) customTab.findViewById(R.id.activity_music_page_content_tab_title);
tabTitle.setTextSize(15);
tabTitle.setText(categoriesTab.get(i).getCategoryName());
tabTitle.setTextColor(ContextCompat.getColor(this, 0));
tabLayout.getTabAt(i).setCustomView(customTab);
}
}
json, который я получаю, содержит идентификатор и название вкладки

"ID": "18",
"CategoryName": "Inside Yerevan"
