Custom Menu ​

When viewing a PDF, selecting text and long-pressing in a blank area triggers the corresponding interactive state in the PDF context. In each interactive state, a context menu similar to a "Menu" will appear, allowing you to perform relevant actions through the menu options.

This example shows how to use an additional context menu that appears when text is selected and a long press is applied to a blank area:

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" />
