this is my adapter:
@SuppressWarnings("unchecked")

groupItem = grList;
this.Childtem = childItem;
}
public void setInflater(LayoutInflater mInflater, Activity act) {
this.minflater = mInflater;
activity = act;
}
public Object getChild(int groupPosition, int childPosition) {
return null;

if (convertView == null) {

}
text = (TextView) convertView.findViewById(R.id.textView1);
text.setText(tempChild.get(childPosition));
//typeface
text.setTypeface(G.typeFacePrs);
//************

TextView text = (TextView) view.findViewById(android.R.id.message);
//text.setText("balabalalalalalal");
//here you can do anything with text

toast.show();

first thing that i can say to you is that you must use tag to each view that make you easy work with your view, and then you don't needed to check the key, like bellow code:
convertView.setTag(groupPosition*100 + childPosition);
with this code you have one unique tag for each child item, then in onClick method you can get you tag like v.getTag(). this get to you your unique tag and you can get your child position easily.
second thing that i see in your code and not true is when you want check your String you use ==. you must use .equal() in String check.
// Edit
you must put seTag() into getChildView().
for the getting your child use following code:
int chiledposClicked = v.getTag() % 100;
int groupPosClicked = v.getTag() / 100;
then you can get your child with
Childtem.get(groupPosClicked).get(chiledposClicked);
Result
public View getChildView(int groupPosition, final int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
final int myGroupPos = groupPosition;
final DisplayMetrics dm = new DisplayMetrics();
activity.getWindowManager().getDefaultDisplay().getMetrics(dm);
previousGroup = myGroupPos;
tempChild = (ArrayList<String>) Childtem.get(groupPosition);
TextView text = null;
if (convertView == null) {
convertView = minflater.inflate(R.layout.childrow, null);
}
convertView.setTag(groupPosition*100 + childPosition);
/*
text = (TextView) convertView.findViewById(R.id.textView1);
text.setText(tempChild.get(childPosition));
//typeface
text.setTypeface(G.typeFacePrs);
*/
//************
convertView.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
int chiledposClicked = v.getTag() % 100;
int groupPosClicked = v.getTag() / 100;
log.d("Group pos and child pos",""+groupPosClicked +" "+ chiledposClicked);
Childtem.get(groupPosClicked).get(chiledposClicked);
log.d("chiled is",Childtem.get(groupPosClicked).get(chiledposClicked));
ReportActivity.mahdiCustomToast(Childtem.get(groupPosClicked).get(chiledposClicked)
, 1);
loadContent(Childtem.get(groupPosClicked).get(chiledposClicked));
}
private void loadContent(String key) {
}
});
return convertView;
}
