How to set text to textViews in android using loop

Question

Here list is an array list. whats happen is the text gets over written and always displays the last value. the size of list is 4.

for (int i = 0; i < list.size(); i ++){
  TextView name = (TextView) convertView.findViewById(R.id.user_names);
  name.setText(list.get(i).toString());
  TextView email = (TextView) convertView.findViewById(R.id.user_emails);
  email.setText(list.get(i).toString());
}

You should be using ListView or Recyclerview. and also you shouldn't use TextView name = (TextView) convertView.findViewById(R.id.user_names); this in a loop. — Siddhesh Dighe

Try to use this solution for example:

private int[] food_list_dates = {
        R.id.date_1,
        R.id.date_2,
        R.id.date_3,
        R.id.date_4,
        R.id.date_5,
        R.id.date_6,
        R.id.date_7,
        R.id.date_8,
        R.id.date_9,
        R.id.date_10,
        R.id.date_11,
        R.id.date_12,
        R.id.date_13,
        R.id.date_14,
};

...

for (int i = 0; i > foodList.size(); i++) {
    ((TextView) findViewById(food_list_dates[i])).setText( i + "" );
}

Just append everything.And as @siddhesh dighe mentioned don't use TextView initialization in loops.

TextView name = (TextView) convertView.findViewById(R.id.user_names);
TextView email = (TextView) convertView.findViewById(R.id.user_emails);

for (int i = 0; i < list.size(); i ++){
  name.append(list.get(i).toString());     
  email.append(list.get(i).toString());
}

Try to use append() instead :

TextView name = (TextView) convertView.findViewById(R.id.user_names);
TextView email = (TextView) convertView.findViewById(R.id.user_emails);
for (int i = 0; i < list.size(); i ++){
  if(i==0)
  {
    name.append(list.get(i).toString());
    email.append(list.get(i).toString());
  }else {
    name.append("," + list.get(i).toString());
    email.append("," + list.get(i).toString());
  }
}

You have an ArrayList with your data and you have a ListView, So you can just use ArrayAdapter for your listView and pass your Arraylist to it.

ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, animalsNameList);
listView.setAdapter(arrayAdapter);
