PON-level ExpandableListView
text
Body
copied!<p>I'm trying to implement a N-level ExpandableListView and I'm using these codes for <code>getChildView</code> and <code>getGroupView</code> :</p> <pre><code> @Override public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View view, ViewGroup parent) { ExpandNode child = (ExpandNode) getChild(groupPosition, childPosition); ExpandNode group = (ExpandNode) getGroup(groupPosition); if (group.hasChild()) { if (view == null) { view = LayoutInflater.from(context).inflate(R.layout.index_expandable_list, null); } ExpandableListView expandableListView = (ExpandableListView) view.findViewById(R.id.myExpandableListView); ExpandAdapter adapter = new ExpandAdapter(context, group.getChilds()); expandableListView.setAdapter(adapter); } else { if (view == null) { view = LayoutInflater.from(context).inflate(R.layout.index_child_row, null); } TextView childTextView = (TextView) view.findViewById(R.id.childTextView); childTextView.setText(child.getTitle().toString()); } return view; } </code></pre> <p>and :</p> <pre><code>@Override public View getGroupView(int groupPosition, boolean isLastChild, View view,ViewGroup parent) { ExpandNode group = (ExpandNode) getGroup(groupPosition); if (view == null) { view = LayoutInflater.from(context).inflate(R.layout.index_parent_row, null); } TextView childTextView = (TextView) view.findViewById(R.id.parentTextView); childTextView.setText(group.getTitle().toString()); return view; } </code></pre> <p>The problem is when I'm using nested adapters like what you see in <code>getChildView</code> , the <code>groupPosition</code> value is always 0 in <code>getGroupView</code> in the inner adapter and always referring to the first value in the arrayList. for example: the values in the arrayList are:</p> <pre><code>Level1 level1_1 level1_2 level1_3 level2 </code></pre> <p>but it shows:</p> <pre><code>Level1 level1_1 level1_1 level1_1 level2 </code></pre> <p>It happens only when I'm using nested adapters and it works when using <code>getChildView</code> like this:</p> <pre><code> @Override public View getChildView(int groupPosition, int childPosition,boolean isLastChild, View view, ViewGroup parent) { ExpandNode child = (ExpandNode) getChild(groupPosition, childPosition); if (view == null) { view = LayoutInflater.from(context).inflate(R.layout.index_child_row, null); } TextView childTextView = (TextView) view.findViewById(R.id.childTextView); childTextView.setText(child.getTitle().toString()); return view; } </code></pre> <p>But it's not a N-level list anymore... Is there ay suggestion how can I fix this?</p> <p>Other implemented methods in my Adapter mentioned below :</p> <pre><code> @Override public Object getChild(int groupPosition, int childPosition) { return groups.get(groupPosition).getChilds().get(childPosition); } @Override public long getChildId(int groupPosition, int childPosition) { return childPosition; } @Override public int getChildrenCount(int groupPosition) { return groups.get(groupPosition).getChilds().size(); } @Override public Object getGroup(int groupPosition) { return groups.get(groupPosition); } @Override public int getGroupCount() { return groups.size(); } @Override public long getGroupId(int groupPosition) { return groupPosition; } @Override public boolean hasStableIds() { return true; } @Override public boolean isChildSelectable(int arg0, int arg1) { return true; } </code></pre>
