我想在单击项目时在ListView项目下面动态创建button
。
以下是单击项目之前和之后的ListView示例
之前:
的Item1
项目2
项目3
点击第2项后:
的Item1
项目2
[Text] [Text] [Button]
项目3
如何在点击的列表视图项下方动态添加一行文本项和按钮?

最好使用 $criteria = new CDbCriteria;
$criteria->join = 'LEFT OUTER JOIN customer AS C ON C.id = t.customer_id AND C.store_id=' . Yii::app()->session['store_id'];
$criteria->select = 'C.firstname as firstname';
$criteria->group = 'C.firstname';
$criteria->condition = 'store_id=\'' . Yii::app()->session['store_id'] . '\'';
$list = CustomerLifecycle::model()->findAll($criteria);
。当您单击父项时,然后在父项下方展开子视图显示。您可以向儿童添加任何视图。
您可以检查以下link以实现消耗性视图。

为列表项目制作自定义布局。在那里设置线性布局并设置为不可见状态。然后,您可以通过使其可见来添加视图。在你的适配器中调用setnotifydatachanged。

如图书馆文档中所述,将其添加到list_item.xml
:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/text"
android:text="Hello World"/>
<!-- this is the button that will trigger sliding of the expandable view -->
<Button
android:id="@+id/expandable_toggle_button"
android:text="More"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/text"
android:layout_alignParentRight="true"
android:layout_alignTop="@id/text"/>
</RelativeLayout>
<!-- this is the expandable view that is initially hidden and will slide out when the more button is pressed -->
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:id="@+id/expandable"
android:background="#000000">
<!-- put whatever you want in the expandable view -->
<Button
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="0.5"
android:text="Action A" />
<Button
android:id="@+id/details"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="0.5"
android:text="Action B"/>
</LinearLayout>
</LinearLayout>
这是你的activity
:
ListView list = ... your list view
ListAdapter adapter = ... your list adapter
// now simply wrap the adapter
// and indicate the ids of your toggle button
// and expandable view
list.setAdapter(new SlideExpandableListAdapter(
adapter,
R.id.expandable_toggle_button,
R.id.expandable
)
);
