2.setTag(),getTag()的在popupWindow
(1)View视图设置Tag(),方便以后获取
<pre name="code" class="java">lv_app_manager.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // TODO Auto-generated method stub dismissPopupWindow(); //用来存放当前的item的坐标值,第一个是x的坐标,第二个是y的坐标 int[] location = new int[2]; //把当前的item的坐标放到int数组里面 view.getLocationInWindow(location); View popupView = View.inflate(AppManagerActivity.this,R.layout.popup_item,null); LinearLayout ll_app_unistall = (LinearLayout) popupView.findViewById(R.id.ll_app_uninstall); LinearLayout ll_app_run = (LinearLayout) popupView.findViewById(R.id.ll_app_start); LinearLayout ll_app_share = (LinearLayout) popupView.findViewById(R.id.ll_app_share); ll_app_unistall.setOnClickListener(AppManagerActivity.this); ll_app_run.setOnClickListener(AppManagerActivity.this); ll_app_share.setOnClickListener(AppManagerActivity.this); //拿到当时点击的条目,并设置到view里面 AppInfo info = (AppInfo) lv_app_manager.getItemAtPosition(position); ll_app_unistall.setTag(info); ll_app_run.setTag(info); ll_app_share.setTag(info);
(2)View视图获得Tag()中的内容
