问题使用意向过滤器从XML获取数据

Question

我需要，当我点击XML文件，将数据从文件传递到应用程序...如果我通过文件的路径静态它的工作...但如果我使用intent filter所以我动态传递数据这是行不通的。我告诉你两个代码：

没有意图过滤器：

File file = new File(Environment.getExternalStorageDirectory() 
         .getAbsolutePath() + "/ordinazioni/26:Maggio:2017-15:02:40 PM.xml"); 


       FileInputStream is = new FileInputStream(file); 

       . . . 

意图过滤器：

Intent intentt = getActivity().getIntent(); 
      String intenttt=intentt.getData().toString(); 
      System.out.println("INTENT:"+intenttt); 
      //File filee = new File(intenttt); 
      File file = new File(Environment.getExternalStorageDirectory() 
        .getAbsolutePath() +intenttt); 
      System.out.println("FILE:"+file); 

      FileInputStream is = new FileInputStream(file); 


      . . . 

谁可以帮我？

的OnCreate：

@Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 





     try { 
      int a=0; 
      String status=""; 
      boolean statuss = false; 
     /* File file = new File(Environment.getExternalStorageDirectory() 
        .getAbsolutePath() + "/ordinazioni/26:Maggio:2017-15:02:40 PM.xml");*/ 

      Intent intentt = getActivity().getIntent(); 

      String intenttt=intentt.getData().toString(); 
      System.out.println("INTENT:"+intenttt); 
      //File filee = new File(intenttt); 
      File file = new File(Environment.getExternalStorageDirectory() 
        .getAbsolutePath() +intenttt); 
      System.out.println("FILE:"+file); 

      FileInputStream is = new FileInputStream(file); 

      DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); 
      DocumentBuilder dBuilder = dbFactory.newDocumentBuilder(); 
      Document doc = dBuilder.parse(is); 

      Element element = doc.getDocumentElement(); 
      element.normalize(); 

      NodeList nList = doc.getElementsByTagName("checkboxes_pizza"); 

      for (int i = 0; i < nList.getLength(); i++) { 
       Node node = nList.item(i); 
       if (node.getNodeType() == Node.ELEMENT_NODE) { 
        Element element2 = (Element) node; 
        //tv1.setText(tv1.getText()+"\nName : " + getValue("name", element2)+"\n"); 
        String id = getValue("id", element2); 
        a = Integer.parseInt(id); 
        status = getValue("status", element2); 

        statuss= Boolean.parseBoolean(status); 

        System.out.println("XML:" + a); 

        hm.add(a); 




        } 

       } 


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





} 




    private static String getValue(String tag, Element element) { 
     NodeList nodeList = element.getElementsByTagName(tag).item(0).getChildNodes(); 
     Node node = nodeList.item(0); 
     return node.getNodeValue();

Answer 1

尝试使用此：

当传递数据，其中filepath是包含您的动态文件路径的字符串：

intent.putExtra("filename",filepath); 

虽然得到它：

String intenttt=intentt.getExtras().getString("filename");
