I am currently developing an App which needs to look up a number of contacts (name and photo) via their phone number. However, this takes several seconds (For each contact: Look up the contact via their phone number, get contact's name & photo).
What would be a good strategy to speed this process up? I realize that I could use my own sqlite db which contains a list of exactly those names and photos I need. With such a database I could only do one query, then get the data for all contacts I need at once. This however would add quite some overhead I am hoping to avoid.
Is there a better (speak: simpler) solution?
Thank you.
you can use CursorAdapter and override bindView() method for example:
@Override
public void bindView(final View view, Context context, final Cursor cursor) {
holder = (ItemHolder) view.getTag();
ImageView icon = holder.getImageView();
TextView name = holder.getName();
final TextView email = holder.getEmail();
icon.setBackgroundResource(R.drawable.contact_icon);
name.setText(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));
final int contactid = cursor.getInt(cursor.getColumnIndex("_id"));
mHandler.post(new Runnable() {
@Override
public void run() {
Cursor emailCursor = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, "contact_id=?", new String[]{String.valueOf(contactid)}, null);
startManagingCursor(emailCursor);
// Log.i("cursor:", emailCursor.getCount()+"");
if(emailCursor!=null){
if(emailCursor.getCount()==0){
email.setText("");
}else {
while(emailCursor.moveToNext()){
String emails = emailCursor.getString(emailCursor.getColumnIndex("data1"));
email.setText(emails);
}
}
}
emailCursor.close();
}
});
you would use ContactsContract.CommonDataKinds.Phone.CONTENT_URI instead of ContactsContract.CommonDataKinds.Email.CONTENT_URI .
