How to put string in edittext from expandable listView?

Question

I have an expandable list of contact numbers and also an editText. I want to set editText with the item that user click from expandable list.I can get the value of item via toast.But I can not setText to editText. I don't find any right way to do that. Here is code:

public class MyExpandableListAdapter extends BaseExpandableListAdapter {

    private final SparseArray<Group> groups;
    public LayoutInflater inflater;
    public Activity activity;
    FormEditText recip;

    public MyExpandableListAdapter(Activity act, SparseArray<Group> groups) {
        activity = act;
        this.groups = groups;
        inflater = act.getLayoutInflater();
    }

    @Override
    public Object getChild(int groupPosition, int childPosition) {
        return groups.get(groupPosition).children.get(childPosition);
    }

    @Override
    public long getChildId(int groupPosition, int childPosition) {
        return 0;
    }

    @Override
    public View getChildView(int groupPosition, final int childPosition,
                             boolean isLastChild, View convertView, ViewGroup parent) {
        final String children = (String) getChild(groupPosition, childPosition);
        TextView text = null;
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.listrow_details, null);
        }

        text = (TextView) convertView.findViewById(R.id.textView1);
        text.setText(children);
        convertView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d("children",children);
                //TODO
                Toast.makeText(activity, children,
                        Toast.LENGTH_SHORT).show();
            }
        });
        return convertView;
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        return groups.get(groupPosition).children.size();
    }

    @Override
    public Object getGroup(int groupPosition) {
        return groups.get(groupPosition);
    }

    @Override
    public int getGroupCount() {
        return groups.size();
    }

    @Override
    public void onGroupCollapsed(int groupPosition) {
        super.onGroupCollapsed(groupPosition);
    }

    @Override
    public void onGroupExpanded(int groupPosition) {
        super.onGroupExpanded(groupPosition);
    }

    @Override
    public long getGroupId(int groupPosition) {
        return 0;
    }

    @Override
    public View getGroupView(int groupPosition, boolean isExpanded,
                             View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.listrow_group, null);
        }
        Group group = (Group) getGroup(groupPosition);
        ((CheckedTextView) convertView).setText(group.string);
        ((CheckedTextView) convertView).setChecked(isExpanded);
        return convertView;
    }

    @Override
    public boolean hasStableIds() {
        return false;
    }

    @Override
    public boolean isChildSelectable(int groupPosition, int childPosition) {
        return false;
    }
}

((SelfSms)activity).runOnUiThread(new Runnable() {
        @Override
        public void run() {
            text.setText(children);
        }
    });

Use this,

        ExpandableListView listView = (ExpandableListView) findViewById(R.id.listView);
        MyExpandableListAdapter adapter = new MyExpandableListAdapter(this,groups);
        listView.setAdapter(adapter);
        listView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
            @Override
            public boolean onChildClick(ExpandableListView parent, View v,
                                        int groupPosition, int childPosition, long id) {

                String children = groups.get(groupPosition).children.get(childPosition);

                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        phone.setText(children );
                    }
                });

                return false;
            }
        });

Also add

      android:focusable="false"; 
      android:clickable="false"; 

To your textview in child layout
