============问题描述============
代码如下
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 = "此联系人暂未输入电话号码";
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;
}
}
}
ContactsContract.CommonDataKinds.Phone.CONTACT_ID 返回的值为null
============解决方案1============
引用 3 楼 bdmh 的回复:
不是所有的都能拿到，由于移动运营商没有把手机号码的数据写入到sim卡中
你这是从外星来的吗
============解决方案2============
把
intent.setType("vnd.android.cursor.item/phone");
改成
intent.setType("vnd.android.cursor.item/phone_v2");
然后去掉重复创建的cursor。
代码如下：
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;
}
}
}
============解决方案3============
这样：
/**读取通讯录异步Handler*/
private AsyncQueryHandler asyncQuery;
/**
* 读取通讯录
*/
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");
}
//异步查询联系人
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); //去掉+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;
}
}
}
