Android ListView displaying one item per page

Android ListView displaying one item per page - java

I have a listview that uses an adapter who receives a string array as an argument. When I look at the listview it displays 1 item then it shows a lot of blank space behind it that is followed by the next item if I scroll down. What could be the problem?
class CustomAdapter extends ArrayAdapter<String> {
CustomAdapter(Context context, String[] camere) {
super(context, R.layout.custom_row, camere);
}
boolean parola = true;
boolean intra = true;
String player_id, room_id;
String siteul = "some_site";
String site;
HashMap<String, String> hash;

Button Buton;
String room_id, nume;
}
ViewHolder ceva;
#Override

holder.camera.setText(variabile[0]);
if (!variabile[1].equals("true")) {

holder.privata.setVisibility(View.INVISIBLE);
}
holder.players.setText(variabile[2]);

In your custom_row.xml :
change the layout_height of the RelativeLayout, ScrollView and the LinearLayout from fill_parent to wrap_content.

From the R.layout.custom_row we can see that you make the root view(RelativeLayout) fill parent and make the height of ScrollView match_parent. So the Scrollview occupy the full screen. The blank space belongs to scrollview. I think you can remove the scrollview and make the root view(RelativeLayout) wrap content.
Try codes below:
<?xml version="1.0" encoding="utf-8"?>

Spinner qtySpinner;
Button order;
public ViewHolder(#NonNull View itemView) {
super(itemView);
order = itemView.findViewById(R.id.order);
qtySpinner = itemView.findViewById(R.id.qtySpinner);
marketName = itemView.findViewById(R.id.marketName);
productNo = itemView.findViewById(R.id.productNo);
page = itemView.findViewById(R.id.page);
mrp = itemView.findViewById(R.id.mrp);
innerPack = itemView.findViewById(R.id.innerPack);
outerPack = itemView.findViewById(R.id.outerPack);
total = itemView.findViewById(R.id.total);
}
}
}
Someone please let me know how can I get and add total cost from each row and show it in lower left area. Any help would be appreciated.
THANKS

You can use array and append the value of each cell in it and never clear it, then create a function in your adapter that return with this array, here you cal add it's items.

anyone can help me whats wrong with my code

You have to place your getText() inside the methode onClick(). Now it's outside and doesn't work.
The line :
"String newJudul = judul_masalah.getText().toString();"
after the line:
"public void onClick(View v){"

The basic concept to create a custom list view in android starts with a custom view .xml that will correspond to the layout of how each individual item will look like. For example if you want each item to have a textview for the name and a checkbox your custom layout will only contain a linear (horizontal) layout with a textview and a check box in. After that on your activity you'll need to create a class that extends Base Adapter. The main roll of this class is to get the data you want (from an array for example) and inflate that info to the layout that you created. I found this tutorial that may help you:
