I have Product class.I want to pass product object one activity to another.
I have implemented like this :
public class Product implements Parcelable{
private double availableQuantity;
private double price;
private String productCode;
private String description;
private String nonStockItemFlag;
private String activeFlag;
private String kitProductFlag;
private double value;
private ArrayList<Product> product;
private double qty;
public Product() {
}
/**
* @param availableQuantity
* @param price
* @param productCode
* @param description
* @param nonStockItemFlag
* @param kitProductFlag
* @param qty
* @param grossValue
* @param value
*/
public Product(double availableQuantity, double price, String productCode,
String description, String nonStockItemFlag, String kitProductFlag,
double qty, double value) {
super();
this.availableQuantity = availableQuantity;
this.price = price;
this.productCode = productCode;
this.description = description;
this.nonStockItemFlag = nonStockItemFlag;
this.kitProductFlag = kitProductFlag;
this.qty = qty;
this.value = value;
}
// setter & getter
public int describeContents() {
return 0;
}
public void writeToParcel(Parcel dest, int flags) {
Bundle b = new Bundle();
b.putParcelableArrayList("enteredProduct", product);
dest.writeBundle(b);
}
public static final Parcelable.Creator<Product> CREATOR = new Parcelable.Creator<Product>() {
public Product createFromParcel(Parcel in) {
Product prod = new Product();
Bundle b = in.readBundle(Product.class.getClassLoader());
prod.product = b.getParcelableArrayList("enteredProduct");
System.out.println("***product***" + prod.product.get(0).getPrice());
return prod;
}
public Product[] newArray(int size) {
return new Product[size];
}
};
This is caller part :
if(productMap.size() >0){
ArrayList<Product> enteredProductList = new ArrayList<Product>(productMap.values());
System.out.println("-enteredProductList --" + enteredProductList.size());
System.out.println("--- " +enteredProductList.get(0).getPrice() );
Bundle b = new Bundle();
b.put开发者_Python百科ParcelableArrayList("enteredProduct", enteredProductList);
Intent showContent = new Intent(getApplicationContext(),RetailerOrderIActivity.class);
showContent.putExtras(b); //Insert the Bundle object in the Intent' Extras
startActivity(showContent);
}else{
Toast.makeText(RetailerOrderActivity.this," You don't have invoice records" ,Toast.LENGTH_SHORT).show();
}
This is receive part :
Bundle b = this.getIntent().getExtras();
ArrayList<Product> p = b.getParcelableArrayList("enteredProduct");
System.out.println("-- RetailerOrderIActivity --" + p.size() );
for(Product s : p){
System.out.println(" --Qty-" + s.getQty());
System.out.println(" --price -" + s.getPrice());
System.out.println(" --code -" + s.getProductCode());
}
The receiving part return null value.But in the sending Activity part contain value.Please correct my code?
what is wrong in my code?
I have lot of property for product entity calss.But i want to set some of entity.
Thanks in advance.
I guess you misunderstood the Parcelable examples. You have to put all needed elements into the parcel, and get it from it later:
To write your object to the parcel, this is needed:
public void writeToParcel(Parcel dest, int flags)
{
dest.writeString(productCodce);
dest.writeString(description);
// and all other elements
}
Plus, you need a constructor receiving a parcel:
public Product(Parcel in)
{
this.productCode=in.readString();
this.description=in.readString();
// and all other elements
}
Your Creator should be something like:
public static final Parcelable.Creator CREATOR = new Parcelable.Creator()
{
public Product createFromParcel(Parcel in) { return new Product(in); }
public Product[] newArray(int size) { return new Product[size]; }
};
Now, at your activity level (NOT in your Product class!):
Push it into extras, use:
bundle.putParcelableArrayList("whatevername",products);
To get it from the extras, use a simple:
ArrayList<Product> products=bundle.getParcelableArrayList("whatevername");
