Reference Library-a library package with custom controls for custom properties

In general, when customizing a control panel and this control has a custom property (for example:panel:closedhandle= "@drawable/foot_bar_right"), you need to define a reference address for this control in the XML ( Example:xmlns:panel= "Http://schemas.android.com/apk/com.example.view")

This allows you to reference your custom control in XML.

<relativelayout xmlns:android= "Http://schemas.android.com/apk/res/android"//the package name where the panel resides   xmlns:panel= "Http://schemas.android.com/apk/com.example.view"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent" >//Custom Control Panel<Com.example.view.Panel Android:id= "@+id/panel"Android:layout_width= "Fill_parent"Android:layout_height= "Wrap_content"Android:layout_alignparentbottom= "true"android:layout_gravity= "Left"panel:closedhandle= "@drawable/foot_bar_right"panel:content= "@+id/panelcontent"Panel:handle= "@+id/panelhandle"Panel:openedhandle= "@drawable/foot_bar_left"panel:position= "Left" > </com.example.view.Panel>

But

When you want to reference a custom control that is a library , and this control also has a custom property, such as on (it has custom properties in Attrs.xml), you cannot reference the package name in the XML when it is referenced in the new project.

Instead, quote:xmlns:panel= "Http://schemas.android.com/apk/res-auto"

<relativelayout xmlns:android= thepackage name    where the "Http://schemas.android.com/apk/res/android"//panel is located Xmlns:panel= "Http://schemas.android.com/apk/res-auto"    android:layout_width= "Match_parent"    Android : layout_height= "Match_parent" >//Custom Control Panel    <com.example.view.panel        android:id= "@+id/ Panel "        android:layout_width=" fill_parent "        android:layout_height=" wrap_content "        android:layout_ Alignparentbottom= "true"        android:layout_gravity= "left"        panel:closedhandle= "@drawable/foot_bar_right"        panel:content= "@+id/panelcontent"        panel:handle= "@+id/panelhandle"        panel:openedhandle= "@ Drawable/foot_bar_left "        panel:position=" left ">    </com.example.view.Panel>
