public class PoliticaTratamientoDatos extends AppCompatActivity
private ImageView imgBotonVolver;
private WebView webViewPolitica;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_politica_tratamiento_datos);
imgBotonVolver = (ImageView) findViewById(R.id.imgBotonVolver);
imgBotonVolver.setOnClickListener(this);
webViewPolitica = (WebView) findViewById(R.id.webViewPolitica);
webViewPolitica.getSettings().setjavascriptEnabled(true);
String pdf = "https://www.bancoagrario.gov.co/canales/Seguridad/Documents/DocTratamientoDatosPersonales.pdf";
webViewPolitica.loadUrl("https://docs.google.com/viewer?url=" + pdf);
//webViewPolitica.loadUrl("https://docs.google.com/viewer?url=" + pdf + "&embedded=true");
这是我的 XML

我不知道我做错了什么，请帮忙！
【问题讨论】：
【参考方案1】：您的 .pdf 来自 Google 文档，Google 正在将您重定向到另一个 URL。
使用下面的代码作为WebView：
webViewPolitica.setWebViewClient(new WebViewClient()
public boolean shouldOverrideUrlLoading(WebView view, String url)
view.loadUrl(url);
return false;
);
编辑：
link 有时在我的浏览器中不起作用，所以我认为 .pdf 链接会导致问题。有时mybrowser在打开it时会出现ERR_CONNECTION_REFUSED。
希望对您有所帮助。
【讨论】：
您检查过我编辑的答案吗？好像是URL连接问题 我建议你下载pdf文件并从本地资源加载它以上是关于如何显示包含 pdf 的 url 并将其显示在 Webview Android Java 中的主要内容，如果未能解决你的问题，请参考以下文章
