Hi I am creating a contact app and have been having an issue when transitioning into a new fragment. I have been 10 hours on this issue, it's driving me to the walls.
As soon as I started like I was learning, I ran into this issue and at a complete loss as to what I should do. If anyone could provide pointers, I would very much appreciate it.
Here is the java class of the codes:
public class ContactPropertyListAdapter extends ArrayAdapter<String> {
private LayoutInflater mInflater;
private List<String> mProperties = null;
private int layoutResource;
private Context mContext;
private String mAppend;
public ContactPropertyListAdapter(@NonNull Context context, @LayoutRes int resource, @NonNull List<String> properties) {
super(context, resource, properties);
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layoutResource = resource;
this.mContext = context;
this.mProperties = properties;
}
//------------------ Stuff to change ---------------------------------------------------
// in replacement of recycler view
//change if more widgets wants to be added
private static class ViewHolder {
TextView property;
ImageView rightIcon;
ImageView leftIcon;
}
//--------------------------------------------------------------------------------------
@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
/**
******* ViewHolder Build Pattern Start *******
*/
// view holds widget in memory ahead of time for efficiency
final ViewHolder holder;
!! WHERE ERROR BEGINS !!
if(convertView == null){
convertView = mInflater.inflate(layoutResource, parent, false);
holder = new ViewHolder();
//------------------ Stuff to change ---------------------------------------------------
holder.property = (TextView) convertView.findViewById(R.id.tvMiddleCardView);
holder.rightIcon = (ImageView) convertView.findViewById(R.id.iconRightCardView);
holder.leftIcon = (ImageView) convertView.findViewById(R.id.iconLeftCardView);
//--------------------------------------------------------------------------------------
//used to store view
convertView.setTag(holder);
}
else{
holder = (ViewHolder) convertView.getTag();
}
//------------------ Stuff to change ---------------------------------------------------
final String property = getItem(position);
holder.property.setText(property);
//check if it's an email or a phone number
//email
if(property.contains("@")) {
holder.leftIcon.setImageResource(mContext.getResources().getIdentifier("@drawable/ic_email", null, mContext.getPackageName()));
}
else if((property.length() != 0)){
holder.leftIcon.setImageResource(mContext.getResources().getIdentifier("@drawable/ic_phone", null, mContext.getPackageName()));
holder.rightIcon.setImageResource(mContext.getResources().getIdentifier("@drawable/ic_message", null, mContext.getPackageName()));
}
//--------------------------------------------------------------------------------------
return convertView;
}
}
