java - My Android app crashes when trying to store SQLite data -

i tried import sqlite sample code android application save , manage data through sqlite, using listview.

in sqlite sample implements addressbook when fill in text fields of new contact , press "save" button save them sqlite, android app crashes, displaying unfortunately application has terminated.i believe problem focused on button save(button1) , line: android:onclick="run" don't understand exact problem.for convenience method "run" implemented in displaycontact.java archive.

the code of button1 in activity_display_contact.xml layout is:

<button       android:id="@+id/button1"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_alignleft="@+id/edittextcity"       android:layout_alignparentbottom="true"       android:layout_marginbottom="28dp"       android:onclick="run"       android:text="@string/save" /> 

the code of displaycontact.java responsible tha layout of listview :

this weird: java code creates activity called "displaycontact" stacktrace says cannot find onclick handler called "run" in activity called "imagetargets". check way development project has been set up.
