java - menuitem.getmenuinfo() returns null for dynamically created views -

-

i have scrollview embedded relativelayout embedded linearlayout.

<?xml version="1.0" encoding="utf-8"?> <scrollview xmlns:android="http://schemas.android.com/apk/res/android"             android:layout_width="fill_parent"             android:layout_height="fill_parent">      <relativelayout         android:layout_width="fill_parent"         android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"         android:paddingleft="16dp" android:paddingright="16dp" android:id="@+id/relativelayout">          <linearlayout             android:orientation="vertical"             android:layout_width="fill_parent"             android:layout_height="wrap_content" android:layout_below="@+id/today"             android:layout_alignparentleft="true" android:id="@+id/linearlayouttoday"             android:animatelayoutchanges="true">         </linearlayout>      </relativelayout>  </scrollview>

i want add context menu checkbox objects, added dynamically shown below.

private void additem() {     checkbox ch = new checkbox(this);     ch.settext("test");     registerforcontextmenu(ch);     linearlayouttoday.addview(ch); }

the issue occurs in oncontextitemselected method, value returned item.getmenuinfo() null.

@override public boolean oncontextitemselected(menuitem item) {     adapterview.adaptercontextmenuinfo info = (adapterview.adaptercontextmenuinfo) item.getmenuinfo();     system.out.println(info.targetview);     return true; }

does know how resolve issue?

this problem caused because add context menu children, add context menu parent. however, supported other views (e.g. listview), not layouts.

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
