public class Article {
    private int id;
    private String title;
    private String author;
    private String publishDate;
    private String content; // 存储HTML片段或富文本
    private String imageUrl;

    // Getter和Setter方法
    // ...
}

// 1. 定义API接口
public interface ArticleApiService {
    @GET("articles/{id}")
    Call<Article> getArticle(@Path("id") int articleId);
}

// 2. 在Activity/Fragment中
public class ArticleDetailActivity extends AppCompatActivity {

    private TextView titleTextView;
    private TextView authorTextView;
    private TextView contentTextView; // 用于显示富文本
    private ImageView headerImageView;

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

        titleTextView = findViewById(R.id.article_title);
        authorTextView = findViewById(R.id.article_author);
        contentTextView = findViewById(R.id.article_content);
        headerImageView = findViewById(R.id.article_header_image);

        // 初始化Retrofit
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("https://api.example.com/")
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        ArticleApiService service = retrofit.create(ArticleApiService.class);

        // 假设文章ID从Intent获取
        int articleId = getIntent().getIntExtra("article_id", 0);

        // 发起网络请求
        service.getArticle(articleId).enqueue(new Callback<Article>() {
            @Override
            public void onResponse(Call<Article> call, Response<Article> response) {
                if (response.isSuccessful() && response.body() != null) {
                    Article article = response.body();
                    titleTextView.setText(article.getTitle());
                    authorTextView.setText("作者: " + article.getAuthor());

                    // 处理富文本内容（如HTML）
                    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
                        contentTextView.setText(Html.fromHtml(article.getContent(), Html.FROM_HTML_MODE_COMPACT));
                    } else {
                        contentTextView.setText(Html.fromHtml(article.getContent()));
                    }

                    // 加载图片 (使用Glide或Picasso等图片加载库)
                    // Glide.with(ArticleDetailActivity.this).load(article.getImageUrl()).into(headerImageView);
                } else {
                    // 处理API错误
                }
            }

            @Override
            public void onFailure(Call<Article> call, Throwable t) {
                // 处理网络请求失败
            }
        });
    }
}

public class WebContentActivity extends AppCompatActivity {

    private WebView webView;

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

        webView = findViewById(R.id.web_view);

        // 启用JavaScript支持 (如果网页需要)
        webView.getSettings().setJavaScriptEnabled(true);

        // 设置WebViewClient，处理页面导航和加载事件
        webView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
                // 允许WebView加载所有URL，而不是打开外部浏览器
                view.loadUrl(request.getUrl().toString());
                return true;
            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
                // 页面开始加载时显示加载动画
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                // 页面加载完成时隐藏加载动画
            }

            @Override
            public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
                super.onReceivedError(view, request, error);
                // 处理加载错误
            }
        });

        // 加载网页
        String urlToLoad = "https://www.geeksforgeeks.org/some-article/"; // 示例URL
        webView.loadUrl(urlToLoad);

        // 如果需要加载本地HTML文件
        // webView.loadUrl("file:///android_asset/my_local_page.html");
    }

    // 处理后退按钮，使WebView返回上一页而不是退出Activity
    @Override
    public void onBackPressed() {
        if (webView.canGoBack()) {
            webView.goBack();
        } else {
