unter Code versucht

MyAdapter

public class ExListAdapter extends BaseExpandableListAdapter { 

     private Activity context; 
     private Map<String, List<String>> collections; 
     private ArrayList<ListDetails> listItem; 
     private TextView txtOk; 

     public ExListAdapter(Activity context, ArrayList<ListDetails> listItem, 
            Map<String, List<String>> collections, TextView txtOk) { 
      this.context = context; 
      this.collections = collections; 
      this.listItem = listItem; 
      this.txtOk = txtOk; 
     } 

     public Object getChild(int groupPosition, int childPosition) { 
      return 1; 
     } 

     public long getChildId(int groupPosition, int childPosition) { 
      return childPosition; 
     } 

     @Nullable 
     public View getChildView(final int groupPosition, final int childPosition, 
           boolean isLastChild, @Nullable View convertView, ViewGroup parent) { 

      LayoutInflater inflater = context.getLayoutInflater(); 

      if (convertView == null) { 
       convertView = inflater.inflate(R.layout.list_child, null); 
      } 

      etChild = (EditText) convertView.findViewById(R.id.etChild); 
txtOk.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 

        etChild.addTextChangedListener(new TextWatcher() { 

       @Override 
       public void onTextChanged(CharSequence s, int start, int before, int count) { 
        // TODO Auto-generated method stub 

       } 

       @Override 
       public void beforeTextChanged(CharSequence s, int start, int count, 
               int after) { 
        // TODO Auto-generated method stub 

       } 

       @Override 
       public void afterTextChanged(Editable s) { 
        // TODO Auto-generated method stub 
        System.out.println("Value : " + childPosition + etChild.getText().toString()); 
        Toast.makeText(context, etChild.getText().toString() + "...", Toast.LENGTH_SHORT).show(); 
       } 
      }); 

      etChild.setOnTouchListener(new View.OnTouchListener() { 
       @Override 
       public boolean onTouch(View v, MotionEvent event) { 
        v.getParent().requestDisallowInterceptTouchEvent(true); 
        switch (event.getAction() & MotionEvent.ACTION_MASK) { 
         case MotionEvent.ACTION_UP: 
          v.getParent().requestDisallowInterceptTouchEvent(false); 
          break; 
        } 
        return false; 
       } 
      }); 
      etChild.addTextChangedListener(new TextWatcher() { 

       @Override 
       public void onTextChanged(CharSequence s, int start, int before, int count) { 
        // TODO Auto-generated method stub 

       } 

       @Override 
       public void beforeTextChanged(CharSequence s, int start, int count,

        System.out.println("Value : " + childPosition + etChild.getText().toString()); 
        Toast.makeText(context, etChild.getText().toString() + "...", Toast.LENGTH_SHORT).show(); 
       } 
      }); 

      return convertView; 
     } 

     public int getChildrenCount(int groupPosition) { 
      return 1; 
     } 

     public Object getGroup(int groupPosition) { 
      return listItem.get(groupPosition).getValue(); 
     } 

     public int getGroupCount() { 
      return listItem.size(); 
     } 

     public long getGroupId(int groupPosition) { 
      return groupPosition; 
     } 

     @Nullable 
     public View getGroupView(final int groupPosition, boolean isExpanded, 
           @Nullable View convertView, ViewGroup parent) { 
      try { 
       if (convertView == null) { 
        LayoutInflater infalInflater = (LayoutInflater) context 
          .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
        convertView = infalInflater.inflate(R.layout.list_group, 
          null); 
       } 

       TextView txtName = (TextView) convertView.findViewById(R.id.txtName); 
       RelativeLayout rlList = (RelativeLayout) convertView.findViewById(R.id.rlList); 

       txtName.setText(mArr.get(groupPosition).getValue()); 
      } catch (Exception e) { 
       Logs.d("view- ExListAdapter", e, getClass().getSimpleName()); 
      } 

      return convertView; 
     } 

     public boolean hasStableIds() { 
      return true; 
     } 

     public boolean isChildSelectable(int groupPosition, int childPosition) { 
      return true; 
     } 

     @Override 
     public void onGroupCollapsed(int groupPosition) { 
      try { 

      } catch (Exception e) { 
      } 

      super.onGroupCollapsed(groupPosition); 
     } 
    } 

aber alle Zeit wird es immer leer, bitte guyz Hilfe, um es zu lösen !!!

Answer 1

Sie können den Text direkt über EditText erhalten wie knapp unter

txtOk.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View v) { 


         String text= etChild.getText().toString(); 

         if(!text.isEmpty()) 
         Toast.makeText(context,text + "...",Toast.LENGTH_SHORT).show(); 


       });
