安卓开发关于手机手机联系人：添加联系人，删除联系人，查找联系人等，，在网上找了一些资料，如下：

public class Lianxiren {
Context context;
public Lianxiren(Context context){
this.context = context;
}
/**
* 添加指定联系人
* @param fulName
* @param tel
* @return
*/
protected Boolean addLinkMan(String fulName,String tel){
Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");
ContentResolver resolver = context.getContentResolver();
ContentValues values = new ContentValues();
long contactid = ContentUris.parseId(resolver.insert(uri, values));
uri = Uri.parse("content://com.android.contacts/data");
//添加姓名
values.put("raw_contact_id", contactid);
values.put(Data.MIMETYPE, "vnd.android.cursor.item/name");
values.put("data1", fulName);
resolver.insert(uri, values);
values.clear();

//添加电话
values.put("raw_contact_id", contactid);
values.put(Data.MIMETYPE, "vnd.android.cursor.item/phone_v2");
values.put("data1", tel);
resolver.insert(uri, values);
values.clear();
return true;

}
protected String allLinkman(){

null, null, null);
if(cursor.moveToFirst()){

.getColumnIndex(ContactsContract.Contacts._ID));

.getString(cursor
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if(sbBuilder.length() == 0){
sbBuilder.append(name);
}
else{
sbBuilder.append("\n"+name);
}
Cursor phones = ((ContentResolver) cursor).query(

while(phones.moveToNext()){

//添加Phone的信息
sbBuilder.append("\t").append(phoneNumber);

}
phones.close();

}
while(cursor.moveToNext());
cursor.close();
return sbBuilder.toString();

}
protected Boolean deleteLinkMan (String fulName,String tel) {

}

return true;
}
/**

public String testContactNameByNumber() throws Exception{
