How can different activities pass data to the same class?

Question

I have two buttons.

Button1 go to A then C

Button2 go to A then B and finally C.

There are values pass between these activities. The problem I faced now is how do I check whether they are data pass from B to C or it is from A to C only so I can set different condition to them.

Activity A

  btnNext.setOnClickListener(new View.OnClickListener() {  //if button1 is clicked
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(getApplicationContext(),C.class);  //pass spinner value and date to next class
                Name = name.getSelectedItem().toString();
                Weather = weather.getSelectedItem().toString();
                Status=status.getSelectedItem().toString();
                intent.putExtra("Name",Name);
                intent.putExtra("Weather",Weather);
                intent.putExtra("Status",Status);
                intent.putExtra("date2",date2);
                startActivity(intent);
            }
        });

   btnForce.setOnClickListener(new View.OnClickListener()  { // if button2 clicked
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(getApplicationContext(),B.class);
                Name = name.getSelectedItem().toString();
                Weather = weather.getSelectedItem().toString();
                Status=status.getSelectedItem().toString();
                intent.putExtra("Name",Name);
                intent.putExtra("Weather",Weather);
                intent.putExtra("Status",Status);
                intent.putExtra("date2",date2);
                startActivity(intent);
            }
        });

Activity B

 goDetails.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) { // if next button is clicked
                Intent intent = new Intent(getApplicationContext(), C.class);
                sub = SubContractors.getText().toString();
                noP = NoPerson.getText().toString();
                noH=NoHours.getText().toString();
                intent.putExtra("sub",sub);
                intent.putExtra("noP",noP);
                intent.putExtra("noH",noH);
                intent.putExtra("name",name);
                intent.putExtra("weather",weather);
                intent.putExtra("status",status);
                intent.putExtra("date",date);
                startActivity(intent);
            }
        });
    }

Activity c

        name = getIntent().getExtras().getString("Name"); // receive name from Information
        weather = getIntent().getExtras().getString("Weather"); //receive weather
        date = getIntent().getExtras().getString("date2"); //receive date
        status = getIntent().getExtras().getString("Status"); // receive status

If has data passes from B, what should I write ?

Add one more key like "from" in Intent and check in C from which Activity Data C launched — ρяσѕρєя K, Dec 03 '15 at 15:48
no example required i think you can do it yourself. like add ` intent.putExtra("from","A");` on Button `btnNext ` Click and same way add ` intent.putExtra("from","B");` on Button `goDetails ` Click . In C check it as `String strFrom = getIntent().getExtras().getString("from"); if(strFrom.equals("A")){//from A}else if(strFrom.equals("B")){//from B}` — ρяσѕρєя K, Dec 03 '15 at 15:53
@MrsEd I saw the link you gave , but sadly it cannot applied to my case — Tony, Dec 03 '15 at 15:58
@ρяσѕρєяK If I write `intent.putExtra("from","A");` ,should I write `intent.putExtra("Name",Name); intent.putExtra("Weather",Weather); intent.putExtra("Status",Status); intent.putExtra("date2",date2);` ? Or the `form` already include everything ? — Tony, Dec 03 '15 at 16:02

You need to pass some value to know from where the call came from. You can uses example ρяσѕρєя K gave you. Or better jet try

startActivityForResult(_new, REQUEST_CODE);

And then

getIntent().getAction()

Take a look at this post to see more examples:
