I have a ListView and a Baseadapter class that attaches the Values to the View. The Adapter class see all the variable except one..i don't know if the variable is beyond the scope of the class or not.. i have checked and i can't seem to find where the problem is from
getView method of the Adapter class
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View vi=convertView;
if(convertView==null)
vi = lf.inflate(R.layout.single_list_item, null);
TextView title = (TextView)vi.findViewById(R.id.drug_title); // title
TextView description = (TextView)vi.findViewById(R.id.drug_description); // description
TextView id = (TextView) vi.findViewById(R.id.drug_id); //id
TextView title_id = (TextView) vi.findViewById(R.id.title_i); //id
Drug drug = data.get(position);
// Setting all values in list view
title.setText(drug.getName());
description.setText(drug.get_desc());
id.setText("drug.getName()"); // where the problem is from
title_id.setText(drug.getName().substring(0, 1));
Typeface tf = Typeface.createFromAsset(this.activity.getAssets(), "Roboto-Thin.ttf");
Typeface vf = Typeface.createFromAsset(this.activity.getAssets(), "RobotoCondensed-Regular.ttf");
title.setTypeface(tf);
title_id.setTypeface(tf);
description.setTypeface(vf);
title_id.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(activity, "This is the letter button", Toast.LENGTH_SHORT).show();
//This is working
}
});
return vi;
}
And then i tried using the List from the MainActivity it seems to be working there.. this is the method
public void CRUDOperation(DBHandler db){
// Inserting Contacts
Log.d("Insert: ", "Inserting ..");
db.addDrug(new Drug("Chloroquine", "The bitter drug that is not slimy"));
db.addDrug(new Drug("Artesunate", "The big drug..PS: I hate it so much"));
// Reading all contacts
Log.d("Reading: ", "Reading all contacts..");
List<Drug> drug = db.getAllDrugs();
for (Drug dg : drug) {
String log = "Id: "+dg.getID()+" , Name: " + dg.getName() + " , Desc: " + dg.get_desc();
Log.d("Name: ", log);
}
}
and this is the error from the log cat

All i needed to do was to change the access modifier of the Drug object i created in the getView() of the Adapter class to final i.e
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View vi=convertView;
if(convertView==null)
vi = lf.inflate(R.layout.single_list_item, null);
TextView title = (TextView)vi.findViewById(R.id.drug_title); // title
TextView description = (TextView)vi.findViewById(R.id.drug_description); // description
TextView id = (TextView) vi.findViewById(R.id.drug_id); //id
TextView title_id = (TextView) vi.findViewById(R.id.title_i); //title_id
View crcl = vi.findViewById(R.id.testo);
final Drug drug = data.get(position); //this line
// Setting all values in list view
title.setText(drug.getName());
description.setText(drug.get_desc());
id.setText(""+drug.getID());
title_id.setText(drug.getName().substring(0, 1));
Typeface tf = Typeface.createFromAsset(this.activity.getAssets(), "Roboto-Thin.ttf");
Typeface vf = Typeface.createFromAsset(this.activity.getAssets(), "RobotoCondensed-Regular.ttf");
title.setTypeface(tf);
title_id.setTypeface(tf);
description.setTypeface(vf);
title_id.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setTitle("Choose a Color");
builder.setView(lf.inflate(R.layout.color_dialog, null));
builder.show();
//Toast.makeText(activity, "test" + drug.getID(), Toast.LENGTH_SHORT).show();
}
});
return vi;
}
Thank you for your time y'all
