EditText Click in CursorAdapter alter my view
Hi everybody I'm new in android. I am getting a problem in CursorAdapter. My UI is as follow
Problem -
- When I click on Plus button without click on EditText, then it working fine , means adding that item to database. Suppose I click on “Aloo Tikki” Plus button then “Aloo Tikki ” goes in database.
When I click on EditText and then click Plus Button then some thing else goes data base. Suppose I click on EditText and then Plus Button of “Aloo Tikki” , then “Reshmi kabab ” goes to database. If I click on EditText and then Plus button of “Corn Tikki” then “Tandori chiken” goes in data base.
Without click on EditText it working fine as I wish.
I am going to post my CursorAdapter code
public class CustAdpt extends CursorAdapter{
private Context mContext;
private LayoutInflater mInflater;
Cursor cursor, c;
private String str_item_id;
private String str_item_type;
private String str_item_name;
private String str_item_cost;
String str_edt_txt_change;
int quantity =1;
double amount =0;
int int_edttxt =2;
int block_not_chk_for_first_click ;
ViewHolder holder;
SQLiteDatabase dh = DatabaseHelpereKOT.getInstance().getDb();
public CustAdpt(Context context, Cursor c) {
super(context, c);
mInflater = LayoutInflater.from(context);
mContext = context;
cursor = c;
System.out.println("cuntrutor custAdpt");
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
holder = (ViewHolder) view.getTag();
System.out.println("inside bind view");
holder.setImType((ImageView) view.findViewById(R.id.veg_nv_image));
holder.setTvTitle((TextView) view.findViewById(R.id.item_name));
holder.setTvPrice((TextView) view.findViewById(R.id.item_cost));
holder.getTvTitle().setText(cursor.getString(cursor.getColumnIndex("item_name")));
holder.getTvPrice().setText(cursor.getString(cursor.getColumnIndex("Item_cost")));
int _id = cursor.getInt(cursor.getColumnIndex("_id"));
view.setTag(R.id.item_name, _id);
String type = cursor.getString(cursor.getColumnIndex("item_type"));
if (type.trim().startsWith("n") || type.trim().startsWith("N")) {
//holder.getImType().setPadding(6, 0, 0, 0);
holder.getImType().setBackgroundResource(R.drawable.non_veg);
} else {
holder.getImType().setBackgroundResource(R.drawable.veg);
}
System.out.println("end of bind view");
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
final ViewHolder holder_newview;
c = cursor;
View convertView;
convertView = mInflater.inflate(R.layout.list_data_item, parent, false);
System.out.println("only once calling of new view method");
block_not_chk_for_first_click =1;
holder_newview = new ViewHolder();
holder_newview.setId(cursor.getInt(0));
System.out.println("check edit text click 11111");
((ImageView) (convertView.findViewById(R.id.add_image)))
.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
System.out.println("button click");
System.out.println("quantity for item :::::::"+int_edttxt);
addToDB(holder_newview.getId());
System.out.println("i m in ryt [palce");
}
});
convertView.setTag(holder_newview);
System.out.println("check edit text click 222222");
return convertView;
}
void addToDB(Integer objId) {
if (objId != null) {
int _id = objId;
boolean flag = true;
System.out.println("on Add button click "+_id);
Cursor cursor = dh.query(DatabaseHelpereKOT.RESTAURANT_menu_temp,
new String[] { "_id", "item_id", "item_type", "item_name","Item_cost"},"_id=?", new String[] { String
.valueOf(_id) }, null, null, null);
if ((cursor != null) && (cursor.getCount() > 0)
&& cursor.moveToFirst() )
{
str_item_id = cursor.getString(cursor.getColumnIndex("item_id"));
str_item_type = cursor.getString(cursor.getColumnIndex("item_type"));
str_item_name = cursor.getString(cursor.getColumnIndex("item_name"));
str_item_cost = cursor.getString(cursor.getColumnIndex("Item_cost"));
amount = int_edttxt*Integer.parseInt(str_item_cost);
System.out.println("iten name ::::::::: "+str_item_name);
cursor.close();
ContentValues orderValues = new ContentValues();
orderValues.put("item_id", str_item_id);
orderValues.put("item_type", str_item_type);
orderValues.put("item_name", str_item_name);
orderValues.put("Item_cost", str_item_cost);
orderValues.put("qty", int_edttxt);
orderValues.put("amount", amount);
dh.insert(DatabaseHelpereKOT.RESTAURANT_menu_order, null, orderValues);
block_not_chk_for_first_click =2;
System.out.println("block not chk after insertion"+block_not_chk_for_first_click);
System.out.println("data inserted at order");
String msg = "Menu Item Added Successfully";
Message msgObject = new Message();
msgObject.what = 1;
msgObject.obj = msg;
addMenuItemHandler.sendMessage(msgObject);
}
}
}
public Handler addMenuItemHandler = new Handler() {
@Override
public void handleMessage(android.os.Message msg) {
if (msg.what == 1) {
System.out.println("inside handler");
Toast.makeText(mContext, (String) msg.obj, Toast.LENGTH_SHORT)
.show();
}
};
};
}

I can't understand why EditText's Click alter Plus Click. Any help is really appreciated. Please some help me , It is SOS situation. Thanks in advance to all.
Solution
There is a problem by maintaining ViewHolder and convertView as global references. These values will get updated when newView() is called every time. and with respect to comments, this will help you...
