我有以下代码:
public String getContactDisplayNameByNumber(String number) {
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
String name = "?";
ContentResolver contentResolver = getContentResolver();
Cursor contactLookup = contentResolver.query(uri, new String[] {BaseColumns._ID,
ContactsContract.PhoneLookup.DISPLAY_NAME }, null, null, null);
try {
if (contactLookup != null && contactLookup.getCount() > 0) {
contactLookup.moveToNext();
name = contactLookup.getString(contactLookup.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
//String contactId = contactLookup.getString(contactLookup.getColumnIndex(BaseColumns._ID));
}
} finally {
if (contactLookup != null) {
contactLookup.close();
}
}
Toast.makeText(this, name, Toast.LENGTH_LONG).show();
return name;
}
在这里,我正在根据完整的联系人电话号码搜索联系人姓名。是否可以仅根据电话号码中的 4 个号码搜索联系人?
