Hi tai1135,
You should post whole adapter code because snippet you provided is not enough.
Regards, Dragan
This is code for Adapter :
package toxter.com.component;
import java.util.ArrayList; import com.loopj.android.image.SmartImageView;
import toxter.com.R; import toxter.com.common.AppConfig; import toxter.com.model.Contact; import android.app.Activity; import android.content.Context; import android.content.Intent; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.Filter; import android.widget.TextView;
public class ListContactAdapter extends ArrayAdapter
public ListContactAdapter(Context context, int textViewResourceId, ArrayList<Contact> objects) {
super(context, textViewResourceId, objects);
this.context = context;
resource = textViewResourceId;
currentList = objects;
origin_array = (ArrayList<Contact>) currentList.clone();
}
@Override
public Filter getFilter() {
return arrayFilter;
}
Filter arrayFilter = new Filter() {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults filterResults = new FilterResults();
ArrayList<Contact> data;
if(constraint != null && constraint.length() != 0) {
data = new ArrayList<Contact>();
for (Contact contact : origin_array) {
if((contact.first_name != null && contact.first_name.toLowerCase().contains(constraint)) || (contact.last_name != null && contact.last_name.toLowerCase().contains(constraint)) || (contact.email != null && contact.email.toLowerCase().contains(constraint))) {
data.add(contact);
}
}
} else {
data = origin_array;
}
filterResults.values = data;
filterResults.count = data.size();
return filterResults;
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
ArrayList<Contact> filteredList = (ArrayList<Contact>) results.values;
if(results != null && results.count > 0) {
clear();
for (Contact c : filteredList) {
add(c);
}
notifyDataSetChanged();
}
}
};
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View contactView = convertView;
if (contactView == null) {
contactView = new ContactView(getContext());
}
final Contact contact = currentList.get(position);
//Display infor in view
if (contact != null) {
TextView lblContactName = ((ContactView) contactView).lblContactName;
TextView lblContactEmail = ((ContactView) contactView).lblContactEmail;
SmartImageView imgContactImage = ((ContactView) contactView).imgContactImage;
lblContactName.setText(AppConfig.GetContactFullName(contact.first_name ,contact.last_name));
lblContactEmail.setText(contact.email);
String image = "";
if(contact.image == null || contact.image.isEmpty()) {
try {
Integer.parseInt(contact.fb_image);
} catch (Exception e) {
image = contact.fb_image ;
}
} else {
image = contact.image;
}
if(image == null || image.isEmpty()) {
imgContactImage.setImageResource(R.drawable.nophoto);
} else {
imgContactImage.setImageUrl(image);
}
//set onClick for item
contactView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Activity activity = (Activity)context;
Intent returnIntent = new Intent();
returnIntent.putExtra("contact", AppConfig.gson.toJson(contact));
activity.setResult(Activity.RESULT_OK,returnIntent);
activity.finish();
}
});
}
return contactView;
}
}
I guess you have valid nophoto.png in your /drawable directory.
Have you checked with debugger or by logging if this line is ever executed imgContactImage.setImageResource(R.drawable.nophoto) ?
You should always handle all cases in getView() even when contact is null - in that case you should set TextViews to empty string and hide ImageView. In case you don't there will be shown items with some random name/email/image even if contact is null.
Do you have any ideas ? Thanks a lots.
Was this issue ever resolved?
@TeknoloGenie : Not yet, long time not work on it.
I resolved the issue we were having. Same outcome as you, not sure if the same issue, but i'll post on this tomorrow with a pull request.
We solved this by assigning a default drawable at view, it is kinda hack but never had problem ever since.
@TeknoloGenie : Have you posted the Solution for this? can you please share it on this thread?
two solutions I found for it were,
Please share any better robust solution. Thanks!
I have a list of contacts. In listView's Adapter, i check if contact have image not null or empty.
But for the case when Image is empty or null, it display another image in the list. (Not the default one).
Here is the code :
if(image == null || image.isEmpty()) { contactImage.setImageResource(R.drawable.nophoto); } else { contactImage.setImageUrl(image); }
Can you help me this ? Thanks a lots.
