Add A Button To A ListView For Each Element

I am creating a shopping cart app and I am trying to populate a String[] Product which is called items. Each item has an ID a Name and a Price. The issue I am having is that I am t

Solution 1:

Change line:

final ListAdapter theAdapter = new ArrayAdapter<>(this,
        android.R.layout.simple_list_item_checked, items);

to:

final ListAdapter theAdapter = new ArrayAdapter<>(this,
           R.layout.row_layout , R.id.textview1, items);

You use wrong ArrayAdapter constructor :) If root view is not a TextView (in your case root view is LinearLayout) you have to pass TextView id       

Solution 2:

You need to implement a ProductsAdapter. The ArrayAdapter constructor you are using is trying to set a list of only check item layouts which is invalid given your product. You will have to create a simple adapter which maps each variable in the Product object to the row_layout.xml.

You can model your adapter after this - https://github.com/ucsunil/receipts/blob/master/app/src/main/java/com/amex/receipts/adapters/ItemsAdapter.java. It is from a practice project I did sometime back which was to add items to a cart. You basically will override the getView() method to bind your views.

Solution 3:

I would create a custom adapter class, and within that adapter class have a callback. You can modify this code to take a String[] or ArrayList and also use your XML Layout.

This sample code is somewhat overkill, but it is the best I could do for providing an example right now.

public class WorkoutCardsAdapter extends ArrayAdapter<WorkoutView> {

private LayoutInflater mInflater;
String TAG = WorkoutCardsAdapter.class.getCanonicalName();
Callback mCallback;
List<WorkoutView> mViews;

public WorkoutCardsAdapter(Context context, List<WorkoutView> views, Callback callback) {
    super(context, 0, views);
    mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    mCallback = callback;
    this.mViews = views;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    final ViewHolder holder;
    WorkoutView workoutView = getItem(position);
    convertView = null;


    if (convertView == null) {
        holder = new ViewHolder();
        if (workoutView.getWorkoutMainCategory().equals("Traditional")) {
            if (workoutView.getWorkoutType().equals("Strength")) {
                if (workoutView.getWorkoutCategory().equals("Weightlifting")) {
                    convertView = mInflater.inflate(R.layout.single_workout_layout_traditional_weights, parent, false);
                    holder.tvWorkoutType = (TextView) convertView.findViewById(R.id.textViewWorkoutTypeItem);
                    holder.tvWorkoutCategory = (TextView) convertView.findViewById(R.id.textViewWorkoutCategoryItem);

Hi try Removing the support library import android.support.v7.app.ActionBarActivity;

And extend Activity not ActionBarActivity. I have tried it and it work fine. The support library has some problems.
