当一个lsitView中每个ietm有多个控件的时候想获得其中的位置，其实主要是item的位置

@Override
public View getView(int position, View convertView, ViewGroup parent) {

// grab view
View v = convertView;
// set view layout
if (v == null) {
LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.layout_inbox_item, null);

CheckBox box = (CheckBox)v.findViewById(R.id.inbox_itemcheck);
if (box != null) {
box.setTag(position); //<-- sets the tag by its position
box.setOnCheckedChangeListener(new CheckBox.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int position = (Integer)buttonView.getTag(); //<-- get the position
}
});
}
}
2.

View getView(int position, View convertView, ViewGroup parent) {

// grab view
View v = convertView;
// set view layout
if (v == null) {
LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.layout_inbox_item, null);

CheckBox box = (CheckBox)v.findViewById(R.id.inbox_itemcheck);
if (box != null) {
box.setOnCheckedChangeListener(new CheckBox.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
ViewGroup v = (ViewGroup)buttonView.getParent().getParent();
int i = v.indexOfChild((View)buttonView.getParent());
}
});
}
}
