I've searched for many post on the internet for my issue but no one is helping me, so I try a new question.I have an Activity with a ListView containing in each row two TextViews (pizza_name,pizza_price) one EditText (pizza_quantity) and two buttons (add_pizza,remove_pizza), I use a custom adapter to fill the ListView.
I have implemented all the methods to make the buttons work properly, my problem is with the pizza_quantity EditText view:I want that the number showed in could be edited both via buttons and user input, well when a user tap on it, the keyboard appears, but the content of the EditText doesn't change.Here are the code of:
single_row_layout:
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_margin="5dp"><TextView android:id="@+id/pizzaname" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:paddingLeft="8dp" android:textSize="18sp" android:textStyle="bold" android:hint="nome_pizza" android:layout_centerVertical="true"/><TextView android:id="@+id/pizzaprice" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toLeftOf="@+id/editTextQuantity" android:textSize="18sp" android:textStyle="bold" android:hint="prezzo" android:layout_centerVertical="true" /><Button android:layout_width="50sp" android:layout_height="wrap_content" android:id="@+id/ib_addnew" android:layout_gravity="bottom" android:hint="+" android:layout_toLeftOf="@+id/ib_remove" android:background="#00ffffff" /><EditText android:layout_width="50dp" android:layout_height="48dp" android:text="0" android:id="@+id/editTextQuantity" android:layout_toLeftOf="@+id/ib_addnew" android:textAlignment="center" android:inputType="numberDecimal" /><Button android:layout_width="50sp" android:layout_height="wrap_content" android:id="@+id/ib_remove" android:hint="-" android:layout_marginRight="5sp" android:layout_alignParentRight="true" android:background="#00ffffff" /></RelativeLayout>the code in main activity (called MenuActivity) in which I set the adapter
onCreate:
@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.menu_layout); Intent i = getIntent(); order = new Order(); Server server = StubServer.getIstance(this); pizzaNames = server.getPizzaNames(); pizzaPrices = server.getPizzaPrices(); if(i.getBooleanExtra("session",false)){ order=(Order)i.getSerializableExtra("order"); } listView = (ListView) findViewById(R.id.mylist); listAdapter = new ListAdapter(this, pizzaNames, pizzaPrices,order.pizzaQuantity); listView.setAdapter(listAdapter); listAdapter.setCustomButtonListener(this);}and this is ListAdapter
constructor:
public ListAdapter(Context context, String[] listViewItems,String[] prices,ArrayList<Integer> q) { this.context = context; this.listViewItems = listViewItems; this.prices=prices; this.quantity=q; if(quantity.size()==0) { for (int i = 0; i < listViewItems.length; i++) { quantity.add(0); } }}getView method:
@Overridepublic View getView(final int position, View convertView, ViewGroup parent) { View row; final ListViewHolder listViewHolder; if(convertView == null) { LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); row = layoutInflater.inflate(R.layout.activity_custom_listview,parent,false); listViewHolder = new ListViewHolder(); listViewHolder.pizzaName = (TextView) row.findViewById(R.id.pizzaname); listViewHolder.price=(TextView) row.findViewById(R.id.pizzaprice); listViewHolder.btnPlus = (Button) row.findViewById(R.id.ib_addnew); listViewHolder.edTextQuantity = (EditText) row.findViewById(R.id.editTextQuantity); listViewHolder.btnMinus = (Button) row.findViewById(R.id.ib_remove); row.setTag(listViewHolder); } else { row=convertView; listViewHolder= (ListViewHolder) row.getTag(); } try{ //HashMap<String, String> map = listQuantity.get(position); //quantity[position]+"" listViewHolder.edTextQuantity.setText(quantity.get(position)+""); //holder.item_name.setText(map.get("name")); //holder.order_qty.setText(map.get("quantity")); //Log.v("Available or not", ""+map.get("available")); }catch(Exception e){ e.printStackTrace(); } listViewHolder.btnPlus.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (customButtonListener != null) { customButtonListener.onButtonClickListener(position, listViewHolder.edTextQuantity, 1); int tmp=quantity.get(position); quantity.set(position,tmp+1); //quantity[position]=[position]+1; } } }); //listViewHolder.edTextQuantity.setText("0"); listViewHolder.btnMinus.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (customButtonListener != null) { customButtonListener.onButtonClickListener(position,listViewHolder.edTextQuantity,-1); if(quantity.get(position)>0) quantity.set(position, quantity.get(position) - 1); } } }); listViewHolder.pizzaName.setText(listViewItems[position]); listViewHolder.price.setText(prices[position]); if(position%2==0){ row.setBackgroundColor(Color.LTGRAY); } return row;}finally, here are two app screenshot
after tap on the first row EditText field
thank you in advance.
