Android应用程序崩溃时，我只在Android 4.4的ListView上使用FeedListAdapter

Question

这是feedlist适配器。当我从活动中调用该应用程序时，应用程序在Android 4.4上崩溃，但代码在5.0和更高版本上正常工作。请帮忙。一直试图解决这个问题大约一周，没有运气。此关联的应用程序崩溃 view.setOnClickListener（新View.OnClickListener（）{

public class FeedListAdapter extends BaseAdapter { 
     private Activity activity; 
     private LayoutInflater inflater; 
     private List<FeedItem> feedItems; 
     private SharedPreferences mAdminPreferences; 


     public FeedListAdapter(Activity activity, List<FeedItem> feedItems) { 
      this.activity = activity; 
      this.feedItems = feedItems; 
     } 

     @Override 
     public int getCount() { 
      return feedItems.size(); 
     } 

     @Override 
     public Object getItem(int location) { 
      return feedItems.get(location); 
     } 

     @Override 
     public long getItemId(int position) { 
      return position; 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 

      if (inflater == null) 
       inflater = (LayoutInflater) activity 
         .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      if (convertView == null) 
       convertView = inflater.inflate(R.layout.feed_item, null); 

      final TextView name = (TextView) convertView.findViewById(R.id.name); 
      final TextView projectid = (TextView) convertView.findViewById(R.id.project_id); 
      TextView timestamp = (TextView) convertView 
        .findViewById(R.id.timestamp); 
      final TextView statusMsg = (TextView) convertView 
        .findViewById(R.id.txtStatusMsg); 
      final TextView url = (TextView) convertView.findViewById(R.id.txtUrl); 
      // final TextView usertype = (TextView) convertView.findViewById(R.id.usertype); 



      FeedItem item = feedItems.get(position); 


      name.setText(item.getName()); 
      projectid.setText(item.getId()); 
      url.setText(item.getUrl()); 

      final String userid = (item.getUserid()); 
      final String story = (item.getStory()); 
      final String coursename = (item.getCourseName()); 
      final String courseduration = (item.getCourseDuration()); 
      final String amount = (item.getAmount()); 
      final String extradetails = (item.getExtraDetails()); 
      final String videourl = (item.getVideoUrl()); 
      final String school = (item.getSchool()); 



      // My code to instantiate buttonclick and get name of item being clicked 

      View view = convertView.findViewById(R.id.layoutclick); 

      view.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        String namegotten = name.getText().toString(); 
        String projectidgotten = projectid.getText().toString(); 
        String msg = statusMsg.getText().toString(); 
        String urlgotten = url.getText().toString(); 


        Toast.makeText(v.getContext(), namegotten + projectidgotten, Toast.LENGTH_SHORT).show(); 


          Collect.getInstance().getActivityLogger() 
            .logAction(this, "downloadBlankForms", "click"); 

        Intent i = new Intent(v.getContext(), Activity_AllForms_Download.class); 

        i.putExtra("id", projectidgotten); 
        v.getContext().startActivity(i); 

       } 
      }); 


      // Chcek for empty status message 
      if (!TextUtils.isEmpty(item.getStatus())) { 
       statusMsg.setText(item.getStatus()); 
       statusMsg.setVisibility(View.VISIBLE); 
      } else { 
       // status is empty, remove from view 
       statusMsg.setVisibility(View.GONE); 
      } 

      // Checking for null feed url 
      if (item.getUrl() != null) { 
       url.setText(Html.fromHtml("<a href=\"" + item.getUrl() + "\">" 
         + item.getUrl() + "</a> ")); 

       // Making url clickable 
       url.setMovementMethod(LinkMovementMethod.getInstance()); 
       url.setVisibility(View.VISIBLE); 
      } else { 
       // url is null, remove from the view 
       url.setVisibility(View.GONE); 
      } 


      return convertView; 
     } 

    }

     convertView.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       String namegotten = name.getText().toString(); 
       String projectidgotten = projectid.getText().toString(); 
       String msg = statusMsg.getText().toString(); 
       String urlgotten = url.getText().toString(); 


       Toast.makeText(v.getContext(), namegotten + projectidgotten, Toast.LENGTH_SHORT).show(); 


         Collect.getInstance().getActivityLogger() 
           .logAction(this, "downloadBlankForms", "click"); 

       Intent i = new Intent(v.getContext(), Activity_AllForms_Download.class); 

       i.putExtra("id", projectidgotten); 
       v.getContext().startActivity(i); 

      } 
     });
