我的需求是做一个快速拨号界面！list列表显示所有联系人Calllog资料！原来的做法在前面的日志中有提到！大概是先查
Cursor phoneCursor = this.managedQuery( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
Cursor phoneCursor = this.managedQuery( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null); 再根据号码来查联系人
if(0 < phoneCursor.getCount()){ phoneCursor.moveToFirst(); // find all contact list while (phoneCursor.getPosition() != phoneCursor.getCount()) { ContactEntity contactentity = new ContactEntity(); contactentity.contact_id = phoneCursor .getLong(phoneCursor .getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID)); contactentity.contacts_phone_type = phoneCursor .getInt(phoneCursor .getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE)); contactentity.contacts_phone_number = phoneCursor .getString(phoneCursor .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)).replace( "-", ""); contactCursor = this.managedQuery( ContactsContract.Contacts.CONTENT_URI, null, ContactsContract.Contacts._ID + "=" + contactentity.contact_id, null, null); contactCursor.moveToFirst(); contactentity.contacts_display_name = contactCursor .getString(contactCursor .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)).replace( "-", ""); Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, contactentity.contact_id); InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(getContentResolver(), uri); if(null != input){ contactentity.contact_phone_bmp = BitmapFactory.decodeStream(input); } // spell name can contactentity.spellName = PinYin.getInstance(this).getPinyinString( contactentity.contacts_display_name); Log.i(TAG, "contactentity.contact_id: " + contactentity.contact_id + " contactentity.contacts_phone_type: " + contactentity.contacts_phone_type + " contactentity.contacts_phone_number: " + contactentity.contacts_phone_number + "contactentity.contacts_display_name: " + contactentity.contacts_display_name + "contactentity.contact_phone_bmp: " + contactentity.contact_phone_bmp); phoneCursor.moveToNext(); customArrayList.add(contactentity); }
if(0 < phoneCursor.getCount()){ phoneCursor.moveToFirst(); // find all contact list while (phoneCursor.getPosition() != phoneCursor.getCount()) { ContactEntity contactentity = new ContactEntity(); contactentity.contact_id = phoneCursor .getLong(phoneCursor .getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID)); contactentity.contacts_phone_type = phoneCursor .getInt(phoneCursor .getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE)); contactentity.contacts_phone_number = phoneCursor .getString(phoneCursor .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)).replace( "-", ""); contactCursor = this.managedQuery( ContactsContract.Contacts.CONTENT_URI, null, ContactsContract.Contacts._ID + "=" + contactentity.contact_id, null, null); contactCursor.moveToFirst(); contactentity.contacts_display_name = contactCursor .getString(contactCursor .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)).replace( "-", ""); Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, contactentity.contact_id); InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(getContentResolver(), uri); if(null != input){ contactentity.contact_phone_bmp = BitmapFactory.decodeStream(input); } // spell name can contactentity.spellName = PinYin.getInstance(this).getPinyinString( contactentity.contacts_display_name); Log.i(TAG, "contactentity.contact_id: " + contactentity.contact_id + " contactentity.contacts_phone_type: " + contactentity.contacts_phone_type + " contactentity.contacts_phone_number: " + contactentity.contacts_phone_number + "contactentity.contacts_display_name: " + contactentity.contacts_display_name + "contactentity.contact_phone_bmp: " + contactentity.contact_phone_bmp); phoneCursor.moveToNext(); customArrayList.add(contactentity); } 经过测试发现性能消耗主要在这个while循环当中！因为在循环当中在加一个查询数据库操作自然慢！
