View的setTag()和getTag()方法的使用

TextView labelText = new TextView(parent.getContext());
labelText.setTag(treeNode); //绑定一个Object对象

labelText.setId(2);
labelText.setText(label);
labelText.setOnClickListener(imageClickListener);
View.OnClickListener imageClickListener = new View.OnClickListener(){
public void onClick(View v) {
final Map<String, Object> treeNodePosition = (Map<String, Object>)v.getTag();//获取所绑定的Object
Log.i("tree","treeNodePosition"+treeNodePosition);
final int stage = (Integer)treeNodePosition.get("stage");
Log.i("tree","treeNodePosition--stage="+treeNodePosition.get("stage"));
final int position = (Integer)treeNodePosition.get("position");
Log.i("tree","treeNodePosition--position="+treeNodePosition.get("position"));

if(treeNodePosition.containsKey("ns")){
Log.i("tree","treeNodePosition--ns="+treeNodePosition.get("ns"));
if(treeNodePosition.get("expanded").equals("1")){
Log.i("tree","treeNodePosition--expanded="+treeNodePosition.get("expanded"));
removeChildTreeNodes(String.valueOf(treeNodePosition.get("id")));
treeNodePosition.put("expanded", "0");
for(int i = 0; i< treeNodes.size(); i++){
Map<String, Object> tempTreeNode = treeNodes.get(i);
tempTreeNode.put("position", i);
}
setTreeNodes(treeNodes);
notifyDataSetChanged();
return;
}
}
