============ Problem Description ============



The code is as follows
package com.example.sysaction;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.annotation.SuppressLint;
import android.annotation.TargetApi;
import android.app.Activity;
import android.content.CursorLoader;
import android.content.Intent;
import android.database.Cursor;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class SysAction extends Activity {
final int PICK_CONTACT = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button bn = (Button)findViewById(R.id.bn);
bn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("vnd.android.cursor.item/phone");
startActivityForResult(intent,PICK_CONTACT);
}
};
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@SuppressLint("NewApi")
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode)
{
case(PICK_CONTACT):
if(resultCode == Activity.RESULT_OK)
{
Uri contactData = data.getData();
CursorLoader cursorLoader = new CursorLoader(this, contactData, null, null, null, null);
Cursor cursor =cursorLoader.loadInBackground();
if(cursor.moveToFirst())
{
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
String phonenumber = "this contact has not entered a phone number yet";
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+contactId, null, null);
if(phones.moveToFirst())
{
phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
EditText show = (EditText)findViewById(R.id.show);
show.setText(name);
EditText phone = (EditText)findViewById(R.id.phone);
phone.setText(phoneNumber);
}
cursor.close();
}
Break;
}
}
}


The value returned by ContactsContract.CommonDataKinds.Phone.CONTACT_ID is null

Reference 3 floor BDMH reply:
Not all can get, because the mobile operator did not put the mobile phone number data written to the SIM card

Put
Intent.settype ("Vnd.android.cursor.item/phone");

Change into
Intent.settype ("Vnd.android.cursor.item/phone_v2");

Then remove the cursor that was created repeatedly.
The code is as follows:
public class SysAction extends Activity {
final int PICK_CONTACT = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sys_action);
Button bn = (Button)findViewById(R.id.bn);
bn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("vnd.android.cursor.item/phone_v2");
startActivityForResult(intent,PICK_CONTACT);
}
};
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@SuppressLint("NewApi")
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode)
{
case(PICK_CONTACT):
if(resultCode == Activity.RESULT_OK)
{
Uri contactData = data.getData();
CursorLoader cursorLoader = new CursorLoader(this, contactData, null, null, null, null);
Cursor cursor =cursorLoader.loadInBackground();
if (cursor.moveToFirst())
{
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
EditText show = (EditText)findViewById(R.id.show);
show.setText(name);
EditText phone = (EditText)findViewById(R.id.phone);
phone.setText(phoneNumber);
}
cursor.close();
}
Break;
}
}
}

Such
/** Read Address Book async handler*/
Private Asyncqueryhandler asyncquery;
/**
* Read Contacts
*/
private void Readcontacts () {
Asyncquery = new Contactasyncqueryhandler (Getcontentresolver ());
Uri uri = uri.parse ("Content://com.android.contacts/data/phones");
string[] projection = {"_id", "Display_name", "Data1", "Sort_key"};
Asyncquery.startquery (0, NULL, URI, projection, null, NULL,
"Sort_key COLLATE localized ASC");
}

Querying contacts asynchronously
Private class Contactasyncqueryhandler extends Asyncqueryhandler {

Public Contactasyncqueryhandler (Contentresolver CR) {
Super (CR);
}

protected void Onquerycomplete (int token, Object cookie, cursor cursor) {
if (cursor! = NULL && cursor.getcount () > 0) {
arraylist<callsitem> list = new arraylist<callsitem> ();
Cursor.movetofirst ();
for (int i = 0; i < Cursor.getcount (); i++) {
Callsitem item = new Callsitem ();
Cursor.movetoposition (i);
String name = cursor.getstring (1);
String number = cursor.getstring (2);
String SortKey = cursor.getstring (3);
if (Number.startswith ("+86")) {
Number = number.substring (3); Remove +86
}
Item.name = name;
Item.number = number;
Item.sort = SortKey;
List.add (item);
System.out.println ("Name:" + name + "Number:" + number + "Sort:" + SortKey);
}
App.alllist = list;
}
}
}
