问题
I am trying to click on a specific child view in a list view item.
Consider ListView with items. Each item is a compound view with child views.
I want firstly select specific list item and than use this item view find child with a specific id and perform a click.
Here is my code for getting list item, but I have tried to continue this chain further to achieve desired goal, but I can't find proper methods.
onData(anything()).inAdapterView(withId(R.id.list_view_books)).atPosition(0).??
Could you please help to find a way to click on the child view of selected item (in this case at 0 position) with id - R.id.button_delete.
I would be grateful for any help.
EDIT*
onData(anything()).inAdapterView(withId(R.id.list_view_books)).atPosition(0) works fine and I can get an element, but I don't know how to click on a child of this element.
Here is my XML file for the item if it helps.

And my adapter
public class CustomAdapter extends ArrayAdapter<Book > implements View.OnClickListener{
private ArrayList<Book> dataSet;
Context mContext;
// View lookup cache
private static class ViewHolder {
Button deleteButton;
// Other fields
}
public CustomAdapter(ArrayList<Book > data, Context context) {
super(context, R.layout.list_view_item_book, data);
this.dataSet = data;
this.mContext=context;
}
@Override
public void onClick(View v) {
switch (v.getId())
{
case R.id.button_delete:
// Delete
break;
.............
}
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Book dataModel = getItem(position);
ViewHolder viewHolder; // view lookup cache stored in tag
final View result;
if (convertView == null) {
viewHolder = new ViewHolder();
LayoutInflater inflater = LayoutInflater.from(getContext());
convertView = inflater.inflate(R.layout.list_view_item_book, parent, false);
// Find views
result=convertView;
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
result=convertView;
}
viewHolder.deleteButton.setOnClickListener(this);
return convertView;
}
}
回答1:
try this:
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
View target = view.findViewById(R.id.button_delete);
target.performClick();
}
});
