如何使用android向上滑动面板

还有这个

xmlns:sothree="http://schemas.android.com/apk/res-auto"

应该

xmlns:sothree="http://schemas.android.com/apk/res/yourpackagename"

所以它应该是

<com.sothree.slidinguppanel.SlidingUpPanelLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:sothree="http://schemas.android.com/apk/res/yourpackagename"

考虑到你有自定义属性

编辑：

看起来你正在使用

https://github.com/umano/AndroidSlidingUpPanel

它是一个库项目,您必须在您的andorid项目中引用它.如上所述,Scodnly缺少android命名空间.以下应该解决它

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >
<com.sothree.slidinguppanel.SlidingUpPanelLayout
    xmlns:sothree="http://schemas.android.com/apk/res-auto"
    android:id="@+id/sliding_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="bottom"
    sothree:panelHeight="68dp"
    sothree:shadowHeight="4dp">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:text="Main Content"
        android:textSize="16sp" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center|top"
        android:text="The Awesome Sliding Up Panel"
        android:textSize="16sp" />
</com.sothree.slidinguppanel.SlidingUpPanelLayout>
</RelativeLayout>
