Question

我想在模拟器中显示pdf。我使用以下代码。

public class PdfActivity extends Activity 
{

public void onCreate(Bundle savedInstanceState) 
{
    URL url;
    Button btn;
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    System.setProperty("http.proxyHost","192.168.0.2");
    System.setProperty("http.proxyPort","8080");

    btn=(Button)findViewById(R.id.press);

    try
    {
      //url=new URL("http://litofinter.es.milfoil.arvixe.com/PDF/Book6.pdf");



    }catch(Exception e)
    {
        e.printStackTrace();
    }

    btn.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) 
        {
            Uri uri = Uri.parse("http://litofinter.es.milfoil.arvixe.com/PDF/Book6.pdf");
             Intent intent = new Intent(Intent.ACTION_VIEW, uri);
             startActivity(intent);

        }
    });

}
}

但它告诉我错误是我的logcat -

Answer 1

没有简单的方法可以做到：

Render a PDF file using Java on Android

Answer 2

您想要打开此位置上显示的pdf http://litofinter.es.milfoil.arvixe.com/PDF/Book6.pdf 所以基本上你想要显示一个html页面，所以使用webview。

Answer 3

如果你想在Android应用程序中打开pdf，请尝试使用谷歌文档 -

   String pdfurl = "http://www.example.com/yourfile.pdf";
   String googleDocsUrl = "http://docs.google.com/viewer?url="+pdfurl;
   Intent intent = new Intent(Intent.ACTION_VIEW);
   intent.setDataAndType(Uri.parse(googleDocsUrl ), "text/html");
