我试图在单击项目时在ListView项下动态创建button
。
以下是单击项目前后的ListView的示例
之前:
项目1
项目2
项目3
单击项目2后:
项目1
项目2[Text] [Text] [Button]
项目3
如何在单击的列表视图项下方动态添加一行文本项和按钮?
最佳答案
选中此library,它会为您提供所需的内容。
如库文档中所述,将其添加到您的list_item.xml
中:
<?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>
并将其发送到您的
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
)
);
