I have ListView that has a an EditText in every row.When i enter the value in the EditText it duplicate itself in every fourth row in the ListView . How can I prevent that.
public class ItemsAdapter extends ArrayAdapter<Items>{
Double Price;
Double Quantity;
String _Quantity;
private int resource;
private LayoutInflater inflater;
private Context context;
Items items;
public ItemsAdapter(Context ctx, int resourceId, List<Items> objects){
super( ctx, resourceId, objects );
resource = resourceId;
inflater = LayoutInflater.from( ctx );
context=ctx;
}
#Override
public View getView ( int position, View convertView, ViewGroup parent ) {
ItemViewHolder viewHolder;
items = getItem( position );
if (convertView == null) {
viewHolder=new ItemViewHolder();
convertView = ( RelativeLayout ) inflater.inflate( resource, null );
viewHolder.txtQuantity =(EditText)convertView.findViewById(R.id.txtQuantity);
viewHolder.lblItemsName=(TextView) convertView.findViewById(R.id.lblItemName);
viewHolder.lblPrice = (TextView) convertView.findViewById(R.id.lblPrice);
} else {
viewHolder = (ItemViewHolder) convertView.getTag();
}
viewHolder.lblItemsName.setText(items.getItemName());
viewHolder.lblPrice.setText(items.getPrice().toString());
return convertView;
}
public class ItemViewHolder {
public EditText txtQuantity ;
public TextView lblItemsName;
public TextView lblPrice;
}
}`
When you start enter the quantity in each cell of ListView, you should save the quantity to the items
After that, you load the quantity from item
... your above code
}
viewHolder.txtQuantity.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
#Override
public void afterTextChanged(Editable s) {
items.setQuantity(s); // set quantity for each item when you enter quantity
}
});
viewHolder.lblItemsName.setText(items.getItemName());
viewHolder.lblPrice.setText(items.getPrice().toString());
viewHolder.txtQuantity.setText(items.getQuantity()); // load quantity for each item
...
Hope this help
The duplication happens because views are recycled in Listview when you scroll. To avoid this you should reset the text in Edittext in getView() method.
If you want to retain the text in EditText when you come back to the view again you should do something like Phan Văn Linh suggested.
I figure it out
public ItemAdapter(Context context, int textViewResourceId,
ArrayList<Cart> productList) {
super(context, textViewResourceId, productList);
this.productList = new ArrayList<Cart>();
this.productList.addAll(productList);
}
#Override
public int getCount() {
return this.productList.size();
};
#Override
public View getView(final int position, View view, ViewGroup parent) {
DecimalFormat df = new DecimalFormat("0.00##");
// productList= DBAdapter.getCartList();
final Cart product = productList.get(position);
if (view == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(R.layout.list_cart, null);
EditText quantity = (EditText) view.findViewById(R.id.txtQuantity);
//attach the TextWatcher listener to the EditText
quantity.addTextChangedListener(new MyTextWatcher(view));
}
TextView ItemNumber=(TextView)view.findViewById(R.id.itemNumber);
ItemNumber.setVisibility(View.GONE);
EditText quantity = (EditText) view.findViewById(R.id.txtQuantity);
quantity.setTag(product);
if(product.getQuantity() != 0){
quantity.setText(String.valueOf(product.getQuantity()));
}
else {
quantity.setText("1");
}
TextView itemNumber = (TextView) view.findViewById(R.id.itemNumber);
itemNumber.setText(product.getItemNumber());
TextView ItemName = (TextView) view.findViewById(R.id.lblItemName);
ItemName.setText(product.getItemName());
TextView price = (TextView) view.findViewById(R.id.lblPrice);
price.setText( df.format(product.getPrice()));
TextView ext = (TextView) view.findViewById(R.id.lblTotal);
if(product.getQuantity() != 0){
ext.setText("$" + df.format(product.getTotal()));
}
else {
ext.setText("");
}
return view;
}
}
private class MyTextWatcher implements TextWatcher {
private View view;
private MyTextWatcher(View view) {
this.view = view;
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
//do nothing
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
//do nothing
}
public void afterTextChanged(Editable s) {
DecimalFormat df = new DecimalFormat("0.00##");
String qtyString = s.toString().trim();
int quantity = qtyString.equals("") ? 0:Integer.valueOf(qtyString);
EditText qtyView = (EditText) view.findViewById(R.id.txtQuantity);
Cart product = (Cart) qtyView.getTag();
if(product.getQuantity() != quantity){
Double currPrice = product.getTotal();
Double extPrice = quantity * product.getPrice();
Double priceDiff = Double.valueOf(df.format(extPrice - currPrice));
product.setQuantity(quantity);
product.setTotal(extPrice);
TextView ext = (TextView) view.findViewById(R.id.lblTotal);
if(product.getQuantity() != 0){
ext.setText("$" + df.format(product.getTotal()));
}
else {
ext.setText("");
}
if(product.getQuantity() != 0){
qtyView.setText(String.valueOf(product.getQuantity()));
}
else {
qtyView.setText("");
}
orderTotal += priceDiff;
TextView cartTotal = (TextView) findViewById(R.id.cartTotal);
cartTotal.setText(df.format(orderTotal));
}
return;

Hi I am using freeze concept in listview,
Row contains Textview and Edit texts,If i change any Edit text it should update the other column Textview is it possible? Currenly i am using https://github.com/InQBarna/TableFixHeaders Android library
Here is my adapter class:
When i change the age in edittext i need to change height based on age input.
public class FamilyNexusAdapter extends BaseTableAdapter {
private final int[] widths = { 100, 100, 100 };
private final float density;
private Vector<ProductMasterBO> items;
public FamilyNexusAdapter(Context context, Vector<ProductMasterBO> items) {
density = context.getResources().getDisplayMetrics().density;
this.items = items;
}
#Override
public int getRowCount() {
return this.items.size();
}
#Override
public int getColumnCount() {
return 3;
}
#Override
public View getView(final int row, int column, View convertView,
ViewGroup parent) {
String headerString[] = { "column 1", "column 2", "column 3",
};
if (row == -1) {
convertView = getLayoutInflater().inflate(
R.layout.item_table_header_first, parent, false);
((TextView) convertView.findViewById(R.id.product_name))
.setText(headerString[column + 1]);
} else{
user= (UserMaster) items.get(row);
if(column==-1){
txt=user.getuserName();
((TextView) convertView.findViewById(R.id.user_name))
.setText(headerString[column + 1]);
}else if(column==1){
txt=user.getage()+"";
EditText age = (EditText) convertView
.findViewById(R.id.age);
age.setText(txt);
age .addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
String ageString= s.toString();
if (!qty.equals("")) {
}}
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {
}
public void onTextChanged(CharSequence s, int start,
int before, int count) {
//i want to handle when i am trying to change age height should be change
}
});
}else if(column==2){
txt=user.getheight()+"";
((TextView) convertView.findViewById(R.id.user_name))
.setText(txt);
}
return convertView;
}
Use a viewHolder pattern and set the tag property of the EditText to refer the TextView.
Here is my adapter code where on edit field edited am calculating the 2 other fields and displaying through TextWatcher. There are 2 issues here.
1. On scroll the values are changing to default values
2. How can I take the new values updated on click of a button
Please help...thanks.

I am using a custom list view which contains two Buttons Yes or No. When I clicked on No button, a layout containing an edit text will be displayed. There are more than 15 items in the list view. When I tried to type and save the value in the edittext of the 1st item using TextWatcher(), then the value is save for both 5th and 1st position ie, the same value is saving in both 1st and 5th position.
The code I am using is:
holder.subQuestionAnswer.addTextChangedListener( new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void afterTextChanged(Editable s) {
questionsModel.get(position).getQuestion_subquestion().get(0).setAnswer(holder.subQuestionAnswer.getText()
.toString());
Log.e("value", "no_active<>"+position+"<>"+questionsModel.get(position).getQuestion_subquestion().get(0).getAnswer().toString());
}
});
}
How can i avoid this?
It is because of recycling of view. Please check the following adapter. Use the logic according to your needs.

But when I scroll, editext still lose content data :(. please help me
ListView recycle it's children to optimise use of the memory. When your EditText item is moved out of the screen it gets used by another item from your list.
This short video from Udacity Android course explains nicely how it works. It takes just 1:40min.
If you want your EditText to remain the text you have to store it yourself within item data and then restore it when your item is shown again.
I have a listview and in each row there are some edittext. On loading for the firsttime I have assigned values to every edittexts and are editable. I can edit the values in that edittext. My problem is that after changing the position of that rows ie: after scrolling I am getting the initial values in that edittexts, not the editted values. I am working on this for the past 6 hours. Any one please help me.

You need to use Viewholder class and initialize edittext every time while inflating list item layout in getview of listview.
if (convertView == null) {
holder = new ViewHolder();
LayoutInflater vi = (LayoutInflater)
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.element_in_game, null);
holder.scoreToUpdate = (EditText) convertView
.findViewById(R.id.elementUpdateScore);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
initScoresToUpdateEditTexts(holder.scoreToUpdate, hint);
holder.scoreToUpdate.setText(scoresToUpdate[tmp_position]);
holder.scoreToUpdate.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start,
int before, int count) {
scoresToUpdate[tmp_position] = s.toString();
}
#Override
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {
}
#Override
public void afterTextChanged(Editable s) {
}
});
return convertView;
}

EditText Content Changes on ListView Scroll
I resolved this issue by implementing following code.
put following code in getview method of adapter class
viewHolder.invAmt.setTag(position);//set tag
holder.edittext_openingstock_baradmin.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
int pos = (Integer) holder.edittext_openingstock_baradmin.getTag();
scoresToUpdate[pos] = s.toString();
}
#Override
public void afterTextChanged(Editable s) {
}
});
} else {
viewHolder = (ViewHolder) rowView.getTag();
}
