How can i get all the data under my Products Firebase database, i only want to get the productName and quantity. the date in the image is my productID not actual date. my problem is i only get one productName and quantity in under the Product table.
so far this is the code i created
=== This is my current code === === this is the onclick method ===
DatabseReference reff = FirebaseDatabase.getInstance().getReference("Cart List");
DatabseReference reff2= FirebaseDatabase.getInstance().getReference("Cart List");
reff.child("User View").child(phoneNumber).child("Products").addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for(DataSnapshot snap: dataSnapshot.getChildren()){
//first get all the dates
String getDates = snap.getKey();
//add all the dates to reff2
reff2.child("User View").child(phoneNumber).child("Products").child.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for(DataSnapshot snap1: dataSnapshot.getChildren()){
//value of product
String myProductName = snap1.child("ProductName").getValue(String.class);
//value of quanity just convert it to int if you want to calculate
String myQuantity= snap1.child("quantity").getValue(String.class);
//add your method
setSMSData(myProductName,myQuantity);
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
});
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
});
=== THis is the setSMSData ====
private void setSMSData (String myProductName, String myQuantity) {
// add the phone number in the data
Uri uri = Uri.parse("smsto:" + "09257777547");
Intent smsSIntent = new Intent(Intent.ACTION_SENDTO, uri);
// add the message at the sms_body extra field
smsSIntent.putExtra("sms_body", "Order "+ myProductName +":"+ myQuantity +" (Sent Via SKIP MOBILE)");
try{
startActivity(smsSIntent);
} catch (Exception ex) {
Toast.makeText(CartActivity.this, "Your sms has failed...",
Toast.LENGTH_LONG).show();
ex.printStackTrace();
}
IF you want to get all the productName and quantity
on a specific number base on your structure you can use this
DatabaseReference reff = FirebaseDatabase.getInstance().getReference("Cart List");
final DatabaseReference reff2= FirebaseDatabase.getInstance().getReference("Cart List");
reff.child("user View").child("09553706928").child("Products").addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for(DataSnapshot snap: dataSnapshot.getChildren()){
String getDate = snap.getKey();
reff2.child("user View").child("09553706928").child("Products").child(getDate).addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for(DataSnapshot snap1: dataSnapshot.getChildren()){
String myProductName = snap1.child("ProductName").getValue(String.class);
Toast.makeText(getApplicationContext(),myProductName,Toast.LENGTH_SHORT).show();
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
});
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
});
And in your method setSMSData()
private void setSMSData(String productName,String quantity) {
// add the phone number in the data
Uri uri = Uri.parse("smsto:" + "09257777547");
Intent smsSIntent = new Intent(Intent.ACTION_SENDTO, uri);
// add the message at the sms_body extra field
smsSIntent.putExtra("sms_body", "Order "+ productName+":"+quantity+" (Sent Via
SKIP MOBILE)");
try{
startActivity(smsSIntent);
} catch (Exception ex) {
Toast.makeText(CartActivity.this, "Your sms has
failed...",
Toast.LENGTH_LONG).show();
ex.printStackTrace();
}
}
});
