Android: Access TextView inside Child of ExpandableListViewActivity

Question

I am using an ExpandableList via ExpandableListViewActivity.

Now, I would like to change the text colour of a certain TextView inside each ChildView. I don't want them all to be the same, rather something like "ok" in green and "error" in red etc.

I did stumble across getExpandableListAdapter().getChildView(...), but I'm unsure what the last parameters (View convertView, ViewGroup parent) are supposed to be. Also I don't quite know if I need to cast the return value (View) into something?

TextView tv = (TextView)this.getExpandableListAdapter().getChildView(0, 0, false, ???, ???).findViewById(R.id.xlist_child_tv);

Kind regards, jellyfish

Solution summary

SimpleExpandableListAdapter expListAdapter = new SimpleExpandableListAdapter(...parameters...){
    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent)
    {
        final View itemRenderer = super.getChildView(groupPosition, childPosition, isLastChild, convertView, parent);
        final TextView tv = (TextView) itemRenderer.findViewById(R.id.kd_child_value);

        if (tv.getText().toString().contentEquals(getString(R.string.true)))
        {
            tv.setTextColor(getResources().getColor(R.color.myred));
        }
        else if (tv.getText().toString().contentEquals(getString(R.string.false)))
        {
            tv.setTextColor(getResources().getColor(R.color.mygreen));
        }
        else
        {
            tv.setTextColor(getResources().getColor(R.color.white));
        }

        return itemRenderer;

    }
};

color resource:

<resources>
    <color name="white">#ffffffff</color>
    <color name="myred">#FFFF3523</color>
    <color name="mygreen">#FFA2CD5A</color>
</resources>
