I need to increment / decrement of cart product.Valuse are increased / decreased.But from here I need to get Total sum of my all cart product. Got some calculation mistakes.So please help me to fix it.

For sorting you need to Collection.sort method of Java and also you need to implement comparable interface for define your comparison.
CartItemoriginal implements Comparable {
public int compareTo(Object obj) { } }
Updated
public class CartItemoriginal implements Comparable<CartItemoriginal > {
private Float val;
private String id;
public CartItemoriginal (Float val, String id){
this.val = val;
this.id = id;
}
#Override
public int compareTo(ToSort f) {
if (val.floatValue() > f.val.floatValue()) {
return 1;
}
else if (val.floatValue() < f.val.floatValue()) {
return -1;
}
else {
return 0;
}
}
#Override
public String toString(){
return this.id;
}
}
and use
Collections.sort(sortList);

I have a Class FoodDialog that extends AlertDialog that I have customized to how I would like it to look.
I am now wanting to edit the positive/negative buttons using an AlertDialog.Builder, however, when I attempt to build an instance of FoodDialog using a builder, I am facing an 'Incompatible types' error where the builder is asking for AlertDialog instead I am providing it with an extension of AlertDialog - is there a way around this?
If not, is there a way I can edit the positive/negative buttons of my custom AlertDialog class FoodDialog?
Below is my FoodDialog class. The yes/no buttons I have there are ones I have created myself, but I would like the ones that are part of the AlertDialog.Builder to appear instead as these buttons get pushed out of sight when the soft keyboard appears:

You can catch your buttons click listener as follows:
yesBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//yes button click code here
}
});
noBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//no button click code here
}
});
You can use the logcat to see if your listener are being fired.

I populates cart items into the list using cursor adapter. My ListView item has
Price TextView
Product Name TextView
Count TextView
Increment Button
Decrement Buttton
When I click the increment / decrement button the value is incremented/ decremented in a certain condition of AFTER TOUCHING THE LISTVIEW ROW,otherwise the count is not changed.
In some case, if I click the 1st row increment button ,item count is incremented in 2nd row.
NOTE:
1. I am populating List using Cursor Adapter.
2. Using Increment & Decrement clicklistener in activity class.
Here is my code:
cartList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(final AdapterView<?> parent, View itemView, final int position, final long rowId) {
txt_cartProduct = (TextView) itemView.findViewById(R.id.cartProduct);
txt_cartQuantity = (TextView) itemView.findViewById(R.id.cartQuantity);
txt_cartPrice = (TextView) itemView.findViewById(R.id.cartPrice);
txt_cartPriceDum = (TextView) itemView.findViewById(R.id.cartPriceDum);
txt_cartCount = (TextView) itemView.findViewById(R.id.cartCount);
img_ivDecrease = (ImageView) itemView.findViewById(R.id.ivDecrease);
img_ivIncrease = (ImageView) itemView.findViewById(R.id.ivIncrease);
but_addTowish = (Button) itemView.findViewById(R.id.addTowish);
but_remove = (Button) itemView.findViewById(R.id.remove);
img_ivIncrease.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
strPrice = txt_cartPrice.getText().toString();
price = Integer.parseInt(strPrice);
int counter = 0;
try {
counter = Integer.parseInt(txt_cartCount.getText().toString());
} catch (NumberFormatException e) {
e.printStackTrace();
}
counter++;
if (counter > 0) {
txt_cartCount.setText(Integer.toString(counter));
txt_cartPrice.setVisibility(View.GONE);
txt_cartPriceDum.setVisibility(View.VISIBLE);
quantity = txt_cartCount.getText().toString();
total = (Integer.parseInt(quantity)) * (price);
netA = String.valueOf(total);
sum += price;
if (sum == 0) {
netAmount = Integer.parseInt(txt_cartPriceDum.getText().toString());
}
netAmount = sum;
Log.e("Sum is", String.valueOf(sum));
txt_cartPriceDum.setText(String.valueOf(total));
cartCount = Integer.parseInt(quantity);
Toast.makeText(context, "netAmount" + netAmount + "\n" + "Total" + total, Toast.LENGTH_SHORT).show();
if (counter == 1) {
cartPrice = price;
cartSum = sum;
}
if (counter == 0) {
cartPrice = 0;
cartSum = 0;
cartCount = 0;
Toast.makeText(context, "Minimum Item is 1", Toast.LENGTH_SHORT).show();
}
int count_check = 1;
if (count_check >= position) {
count_check++;
} else if (count_check == 0) {
Toast.makeText(context, "Minimum Item is 1", Toast.LENGTH_SHORT).show();
}
}
}
});
img_ivDecrease.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
strPrice = txt_cartPrice.getText().toString();
price = Integer.parseInt(strPrice);
int counter = 0;
try {
counter = Integer.parseInt(txt_cartCount.getText().toString());
} catch (NumberFormatException e) {
e.printStackTrace();
}
counter--;
if (counter > 0) {
txt_cartCount.setText(Integer.toString(counter));
txt_cartPrice.setVisibility(View.GONE);
txt_cartPriceDum.setVisibility(View.VISIBLE);
quantity = txt_cartCount.getText().toString();
total = (Integer.parseInt(quantity)) * (price);
netA = String.valueOf(total);
sum -= price;
if (sum == 0) {
netAmount = Integer.parseInt(txt_cartPriceDum.getText().toString());
}
Log.e("Sum - is", String.valueOf(sum));
txt_cartPriceDum.setText(String.valueOf(total));
cartCount = Integer.parseInt(quantity);
Toast.makeText(context, "netAmount" + netAmount + "\n" + "Total" + total, Toast.LENGTH_SHORT).show();
if (counter == 1) {
cartPrice = price;
cartSum = sum;
}
if (counter == 0) {
cartPrice = 0;
cartSum = 0;
cartCount = 0;
}
}
}
});
}
});

You can use setTag() and getTag() methods for saving the counter value in each list item.

I developed an android application in which a users provides 6 pieces of information in 6 separate text boxes (information such as first name, last name, middle name, mobile number email id etc)
When the user presses a Save button, I need to store this information and be able to recall this information when the Recall button is pressed.
What is the next step to accomplish this
My code so far is below:

db = openOrCreateDatabase("MyDBI", MODE_PRIVATE, null);
db.execSQL("CREATE TABLE IF NOT EXISTS TABLE1 ();");
You can create database using this code
db.execSQL("INSERT INTO TABLE1 VALUES('"+fname"');
And values can be inserted to this database using this code.
A tablelayout can be created and the saved details can be displayed in this tablelayout. Give clickable option and clicking all the details can be transferred using intents to the previous activity.

I have 10 spinner and 10 edit text (user are able to let several spinner and edit text blank), and I also have 2 button to sum value from the selected spinner object and edit text. It's successful to sum the value, but when I use my reset button to get back to the initial state when the app is first launched, I got the problem. The result is wrong, I got the value from the first operation even though I have set it back to the default. This is my code for the reset button
hapus.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
qty1.setText(null);
qty2.setText(null);
qty3.setText(null);
qty4.setText(null);
qty5.setText(null);
qty6.setText(null);
qty7.setText(null);
qty8.setText(null);
qty9.setText(null);
qty10.setText(null);
spin1.setSelection(0);
spin2.setSelection(0);
spin3.setSelection(0);
spin4.setSelection(0);
spin5.setSelection(0);
spin6.setSelection(0);
spin7.setSelection(0);
spin8.setSelection(0);
spin9.setSelection(0);
spin10.setSelection(0);
sum.setText(null);
hasil = 0;
}
});

Any help will be appreciate, thanks

You are trying to use null as a String:
if (item.equals("null"))
It should be:
if (item == null)
Also the default value of an Spinner or EditText is an empty String (i.e. "") not null. I believe you should use .setText(""); when you reset the values, so really that first if statement should be:
if (item.isEmpty()) // or item.equals("")
Lastly do you have 10 OnItemSelectedListeners that contains 80-90% of the same code? If so your should write one generic listener and use parent.getId() to determine which value to set.
