android开发怎样获取通讯录联系人信息

在Android开发中,我经常会遇到需要获取手机通讯录联系人信息,Android手机的通讯录联系人全部都存在系统的数据库中，如果须要获得通讯里联系人的信息就须要访问系统的数据库，才能将信息获取出来。
下面直接贴出代码供大家参考:
程序文件java代码:
import java.io.InputStream;

public class ContactsActivity extends ListActivity {

setListAdapter(myAdapter);

mListView.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView adapterView, View view,
int position, long id) {
//调用系统方法拨打电话
Intent dialIntent = new Intent(Intent.ACTION_CALL, Uri
.parse("tel:" + mContactsNumber.get(position)));
startActivity(dialIntent);
}
});

super.onCreate(savedInstanceState);
}

/**得到手机通讯录联系人信息**/
private void getPhoneContacts() {
ContentResolver resolver = mContext.getContentResolver();

// 获取手机联系人
Cursor phoneCursor = resolver.query(Phone.CONTENT_URI,PHONES_PROJECTION, null, null, null);

if (phoneCursor != null) {
while (phoneCursor.moveToNext()) {

//得到手机号码
String phoneNumber = phoneCursor.getString(PHONES_NUMBER_INDEX);
//当手机号码为空的或者为空字段 跳过当前循环
if (TextUtils.isEmpty(phoneNumber))
continue;

//得到联系人名称
String contactName = phoneCursor.getString(PHONES_DISPLAY_NAME_INDEX);

//得到联系人ID
Long contactid = phoneCursor.getLong(PHONES_CONTACT_ID_INDEX);

//得到联系人头像ID
Long photoid = phoneCursor.getLong(PHONES_PHOTO_ID_INDEX);

//得到联系人头像Bitamp
Bitmap contactPhoto = null;

//photoid 大于0 表示联系人有头像 如果没有给此人设置头像则给他一个默认的
if(photoid > 0 ) {
Uri uri =ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI,contactid);
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(resolver, uri);
contactPhoto = BitmapFactory.decodeStream(input);
}else {
contactPhoto = BitmapFactory.decodeResource(getResources(), R.drawable.contact_photo);
}

mContactsName.add(contactName);
mContactsNumber.add(phoneNumber);
mContactsPhonto.add(contactPhoto);
}

phoneCursor.close();
}
}

/**得到手机SIM卡联系人人信息**/
private void getSIMContacts() {
ContentResolver resolver = mContext.getContentResolver();
// 获取Sims卡联系人
Uri uri = Uri.parse("content://icc/adn");
Cursor phoneCursor = resolver.query(uri, PHONES_PROJECTION, null, null,
null);

if (phoneCursor != null) {
while (phoneCursor.moveToNext()) {

// 得到手机号码
String phoneNumber = phoneCursor.getString(PHONES_NUMBER_INDEX);
// 当手机号码为空的或者为空字段 跳过当前循环
if (TextUtils.isEmpty(phoneNumber))
continue;
// 得到联系人名称
String contactName = phoneCursor
.getString(PHONES_DISPLAY_NAME_INDEX);

//Sim卡中没有联系人头像

mContactsName.add(contactName);
mContactsNumber.add(phoneNumber);
}

phoneCursor.close();
}
}

class MyListAdapter extends BaseAdapter {
public MyListAdapter(Context context) {
mContext = context;
}

public int getCount() {
//设置绘制数量
return mContactsName.size();
}

@Override
public boolean areAllItemsEnabled() {
return false;
}

public Object getItem(int position) {
return position;
}

public long getItemId(int position) {
return position;
}

public View getView(int position, View convertView, ViewGroup parent) {
ImageView iamge = null;
TextView title = null;
TextView text = null;
if (convertView == null) {
convertView = LayoutInflater.from(mContext).inflate(
R.layout.colorlist, null);
iamge = (ImageView) convertView.findViewById(R.id.color_image);
title = (TextView) convertView.findViewById(R.id.color_title);
text = (TextView) convertView.findViewById(R.id.color_text);
}
//绘制联系人名称
title.setText(mContactsName.get(position));
//绘制联系人号码
text.setText(mContactsNumber.get(position));
//绘制联系人头像
iamge.setImageBitmap(mContactsPhonto.get(position));
return convertView;
}

}
}

读取的主要方法：
/*
* 读取联系人的信息
*/
public void testReadAllContacts() {
Cursor cursor = this.getContext().getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
int contactIdIndex = 0;
int nameIndex = 0;

if(cursor.getCount() > 0) {
contactIdIndex = cursor.getColumnIndex(ContactsContract.Contacts._ID);
nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
}
while(cursor.moveToNext()) {
String contactId = cursor.getString(contactIdIndex);
String name = cursor.getString(nameIndex);
Log.i(TAG, contactId);
Log.i(TAG, name);

/*
* 查找该联系人的phone信息
*/
Cursor phones = this.getContext().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId,
null, null);
int phoneIndex = 0;
if(phones.getCount() > 0) {
phoneIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
}
while(phones.moveToNext()) {
String phoneNumber = phones.getString(phoneIndex);
Log.i(TAG, phoneNumber);
}

/*
* 查找该联系人的email信息
*/
Cursor emails = this.getContext().getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + "=" + contactId,
null, null);
int emailIndex = 0;
if(emails.getCount() > 0) {
emailIndex = emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
}
while(emails.moveToNext()) {
String email = emails.getString(emailIndex);
Log.i(TAG, email);
}

}
}
