Android如何使用viewpager从json动态添加标签

// 解析JSON数据获取标签信息
String json = "your_json_data";
JSONArray jsonArray = new JSONArray(json);
List<String> tags = new ArrayList<>();
for (int i = 0; i < jsonArray.length(); i++) {
    JSONObject jsonObject = jsonArray.getJSONObject(i);
    String tagName = jsonObject.getString("name");
    tags.add(tagName);
}

// 创建自定义的FragmentPagerAdapter类
public class MyPagerAdapter extends FragmentPagerAdapter {
    private List<String> tags;

    public MyPagerAdapter(FragmentManager fm, List<String> tags) {
        super(fm);
        this.tags = tags;
    }

    @Override
    public Fragment getItem(int position) {
        String tagName = tags.get(position);
        return MyFragment.newInstance(tagName);
    }

    @Override
    public int getCount() {
        return tags.size();
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return tags.get(position);
    }
}

// 创建自定义的Fragment类
public class MyFragment extends Fragment {
    private String tagName;

    public static MyFragment newInstance(String tagName) {
        MyFragment fragment = new MyFragment();
        Bundle args = new Bundle();
        args.putString("tag", tagName);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            tagName = getArguments().getString("tag");
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_layout, container, false);
        // 根据tagName加载对应的标签内容
        // ...
        return view;
    }
}

// 在Activity中设置ViewPager和TabLayout
ViewPager viewPager = findViewById(R.id.viewPager);
TabLayout tabLayout = findViewById(R.id.tabLayout);
List<String> tags = getTagsFromJson(json); // 解析JSON数据获取标签信息
MyPagerAdapter pagerAdapter = new MyPagerAdapter(getSupportFragmentManager(), tags);
viewPager.setAdapter(pagerAdapter);
tabLayout.setupWithViewPager(viewPager);
