我试图实现从网站下载的预制库,以便在我的listview中使用它。它被称为可扩展列表视图,我想我们都知道那是什么。但是在它的xml文件中,它的listview是这样的:
<?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>
但是我们都知道数组列表需要listview只需要textview才能工作,否则它会抛出异常,有人可以指导我这些东西如何在数组列表上工作吗?感谢
