android - Cannot Type EditText in ExpandableListView Child

Question

i am using expandableList and each child has its edittext to enter a number... when the child is pressed, the edittext shows. if it is not, the edittext stays invisible.. but when i tap on the edittext, the keyboard shows in number (because i set type input : number) only 1 second. after that it turns to common keyboard. even it backs to common keyboard, still, i cant type on the edittext... here is my code

 public View getChildView(int groupPosition, int childPosition,
            boolean isLastChild, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        final String childText = (String) getChild(groupPosition, childPosition);
        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) this.context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(
                    R.layout.konsumsi_user_expand_listchild, null);
        }
        final TextView listChild = (TextView) convertView
                .findViewById(R.id.lblListItemKonsumsi);
        listChild.setText(childText);
        final EditText kolomTakaran = (EditText) convertView
                .findViewById(R.id.kolomTakaran);
        listChild.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                kolomTakaran.setVisibility(View.VISIBLE);

                if (childText == "kol") {
                    takaran = 50;
                } else {
                    takaran = 0;
                }
                kolomTakaran.addTextChangedListener(new TextWatcher() {

                    @Override
                    public void onTextChanged(CharSequence s, int start,
                            int before, int count) {
                        // TODO Auto-generated method stub
                        Toast.makeText(context, "a", Toast.LENGTH_LONG).show();
                    }

                    @Override
                    public void beforeTextChanged(CharSequence s, int start,
                            int count, int after) {
                        Toast.makeText(context, "b", Toast.LENGTH_LONG).show();
                        // TODO Auto-generated method stub

                    }

                    @Override
                    public void afterTextChanged(Editable s) {
                        // TODO Auto-generated method stub
                        Toast.makeText(context, "c", Toast.LENGTH_LONG).show();
                        takaran = Integer.parseInt(s.toString());
                    }
                });
            }
        });

        return convertView;
    }

These settings are required:

In the UI code:

expListView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);

In the AndroidManifest.xml for the Activity:

activity android:name=".YourActivity" android:windowSoftInputMode="adjustPan"
