自定义菜单

在查看 PDF 时，选择文本并在空白区域长按后，PDF 上下文将进入相应的交互状态。在不同的交互状态下都会弹出类似“Menu”的上下文菜单，您可以通过上下文菜单选项进行相关操作。

以下是选择文本并长按空白区域时的附加上下文菜单的示例：

t_markup_annot_menu_layout.xml:

xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg_context_menu_window"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/attr"
				android:layout_width="wrap_content"
    		android:layout_height="wrap_content"
        android:text="attribute" />

    <TextView
        android:id="@+id/copy"
        android:layout_width="wrap_content"
    		android:layout_height="wrap_content"
        android:text="copy" />

    <TextView
        android:id="@+id/delete"
        android:layout_width="wrap_content"
    		android:layout_height="wrap_content"
        android:text="@string/delete" />

</LinearLayout>
