滑块菜单查看问题

Question

我曾经在一个单独的项目实施的ListView用头从源码是这样的：

当我在滑块菜单的位置来实现onClick()，它显示在滑块菜单，而不是在后台View

onCreate()代码片断

if(position == 3) 
{ 
    mAdapter = new MyCustomAdapter(); 
    mAdapter.addSeparatorItem(q.get(0).getA_name()); 
    mAdapter.addItem(q.get(0).getAS_name()); 
    for (int i = 1; i < 460; i++) { 
     if (!(q.get(i).getA_name().trim().equals(q.get(i-1).getA_name().trim()))) { 
      mAdapter.addSeparatorItem(q.get(i).getA_name()); 
      c++; 
     } 
     mAdapter.addItem(q.get(i).getAS_name()); 
    } 
    setListAdapter(mAdapter); 
    toggleMenu(arg1); 
} 

适配器类

//Adapter Class 
private class MyCustomAdapter extends BaseAdapter { 

     private static final int TYPE_ITEM = 0; 
     private static final int TYPE_SEPARATOR = 1; 
     private static final int TYPE_MAX_COUNT = TYPE_SEPARATOR + 1; 

     private ArrayList<String> mData = new ArrayList<String>(); 
     private LayoutInflater mInflater; 

     private TreeSet<Integer> mSeparatorsSet = new TreeSet<Integer>(); 

     public MyCustomAdapter() { 
      mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     } 

     public void addItem(final String item) { 
      mData.add(item); 
      notifyDataSetChanged(); 
     } 

     public void addSeparatorItem(final String item) { 
      mData.add(item); 
      // save separator position 
      mSeparatorsSet.add(mData.size() - 1); 
      notifyDataSetChanged(); 
     } 

     @Override 
     public int getItemViewType(int position) { 
      return mSeparatorsSet.contains(position) ? TYPE_SEPARATOR : TYPE_ITEM; 
     } 

     @Override 
     public int getViewTypeCount() { 
      return TYPE_MAX_COUNT; 
     } 

     public int getCount() { 
      return mData.size(); 
     } 

     public String getItem(int position) { 
      return mData.get(position); 
     } 

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

     public View getView(final int position, View convertView, ViewGroup parent) { 
      ViewHolder holder = null; 
      int type = getItemViewType(position); 
      System.out.println("getView " + position + " " + convertView + " type = " + type); 
      if (convertView == null) { 
       holder = new ViewHolder(); 
       switch (type) { 
        case TYPE_ITEM: 
         convertView = mInflater.inflate(R.layout.activity_main1, null); 
         holder.textView = (TextView)convertView.findViewById(R.id.text); 
         holder.textView.setOnClickListener(new View.OnClickListener() { 
          @Override 
          public void onClick(View v) { 
           AlertDialog.Builder nointernetconnection = new AlertDialog.Builder(
             temp); 
           nointernetconnection 
             .setIcon(R.drawable.ic_launcher) 
             .setTitle(q.get(position-1).getAS_name()) 
             .setMessage(q.get(position-1).getDesc_art()) 
             .setCancelable(true) 
             .setPositiveButton("OK", 
               new DialogInterface.OnClickListener() { 
                @Override 
                public void onClick(DialogInterface arg, 
                  int arg1) { 

                } 
               }); 
           AlertDialog a = nointernetconnection.create(); 
           a.show(); 
          } 
         }); 
         break; 
        case TYPE_SEPARATOR: 
         convertView = mInflater.inflate(R.layout.activity_main2, null); 
         holder.textView = (TextView)convertView.findViewById(R.id.textSeparator); 
         break; 
       } 
       convertView.setTag(holder); 
      } else { 
       holder = (ViewHolder)convertView.getTag(); 
      } 
      holder.textView.setText(mData.get(position)); 
      return convertView; 
     } 

    } 

    public static class ViewHolder { 
     public TextView textView; 
    } 

所以，MyCustomAdapter类dispalying在滑动菜单列表。但是这个列表不应该显示在滑动菜单中，而应该显示在滑动菜单的后面。我希望问题清楚。请告诉我的错误。

您调用的setlistadapter方法是针对滑块调用的，而不是您在背景中的活动/片段上的列表视图。 做一个ListView list = (ListView) getactivity().findViewById(R.id.yourListViewName)或类似的东西，然后设置列表适配器。
