2.Java implementation code as follows

The entry file for the A,mainactivity.java program to run

Package com.example.myandroid;
Import java.util.ArrayList;
Import Java.util.HashMap;
Import Java.util.Iterator;
Import android.app.Activity;
Import Android.content.ContentResolver;
Import android.content.Intent;
Import Android.database.Cursor;
Import Android.net.Uri;
Import Android.os.Bundle;
Import Android.provider.ContactsContract;
Import Android.provider.ContactsContract.CommonDataKinds;
Import Android.view.ContextMenu;
Import Android.view.ContextMenu.ContextMenuInfo;
Import Android.view.MenuItem;
Import Android.view.View;
Import Android.view.View.OnCreateContextMenuListener;
Import Android.widget.AdapterView;
Import Android.widget.AdapterView.OnItemClickListener;
Import Android.widget.ListView;
Import Android.widget.SimpleAdapter;
Import Android.widget.Toast;
Import Com.ymw.details.Detail; public class Mainactivity extends activity {@Override public void onCreate (Bundle savedinstancestate) {super.oncreate (SA
Vedinstancestate);
Setcontentview (R.layout.main); Final ListView ListvieW = (ListView) Findviewbyid (R.id.listview);
Generate dynamic array, add data arraylist 

B,detail.java main interface long by menu display contact details of the jump interface, accept the main interface from the parameters

Package com.ymw.details;
Import COM.EXAMPLE.MYANDROID.R;
Import android.app.Activity;
Import android.content.Intent;

Intent Intent = Getintent ();
String Strpara = Intent.getstringextra ("YMW");
TextView Tview = (TextView) Findviewbyid (R.ID.YMW);
Tview.settext (Strpara);
}

3. Access to mobile phone contacts and dial-up texting, etc. need to configure permissions

Add the following code to the application node in the Androidmanifest.xml file

<!--add permissions-->
<uses-permission android:name= "Android.permission.SEND_SMS"/>
< Uses-permission android:name= "Android.permission.CALL_PHONE"/>
<uses-permission android:name= " Android.permission.READ_CONTACTS "/>
