在我的 ExpandableListView 中,每个子行都包含一个 CheckBox 和一个 TextView。当我点击 TextView 时,一切正常(终于!)。但是,当我点击复选框时,它的状态会发生变化,但 onClick 事件永远不会触发。没有错误,但没有真正发生。
我希望 textview 和 checkbox 都调用相同的行为(即用户应该能够单击行上的任意位置并且将产生相同的行为)。我究竟做错了什么?谢谢!
public class ExpandListAdapter extends BaseExpandableListAdapter {
public ExpandListAdapter(Context context, ArrayList<ExpandListGroup> groups) {
this.context = context;
this.groups = groups;
}
@Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View view, final ViewGroup parent) {
view = getCategoryChildView(groupPosition, childPosition, view);
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//this works for the textview click but
//doesn't fire when the check box is clicked
System.err.println("child clicked");
}
});
return view;
}
private View getCategoryChildView(int groupPosition, int childPosition, View view) {
ClientFinderCategories child = (ClientFinderCategories) getChild(groupPosition, childPosition);
ViewHolder holder;
if (view == null) {
holder = new ViewHolder();
LayoutInflater inflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.expandlist_child_item_category, null);
holder.checkBox = (CheckBox) view.findViewById(R.id.check_box);
holder.textView = (TextView) view.findViewById(R.id.expand_list_item);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
try {
holder.checkBox.setChecked(child.getIsSelected());
holder.textView.setText(child.getCategory());
} catch (Exception e) {}
return view;
}
}
