当前代码：

package com.example.murarilal.volley;

import android.content.Intent;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class ArticleActivity extends AppCompatActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_article);
        String url="https://newsapi.org/v1/articles?source=techcrunch&apiKey=59b308aec9f242fe98b527ab9ba93199";


        WebView webView=(WebView)findViewById(R.id.webView);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.setWebViewClient(new WebViewClient());

        Intent intent=getIntent();
        webView.loadDataWithBaseURL(url,null,intent.getStringExtra("description"),"text/html","UTF-8");
        webView.loadUrl(url);



    }

}

改变这个：

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Hero hero = heroList.get(i);
                Intent intent=new Intent(getApplicationContext(),ArticleActivity.class);
                intent.putExtra("description",hero.getDescription());
                startActivity(intent);

            }
        });
