How to pass value using Intent between Activity in Android?

Question

I want to pass the value of the position in one activity class to another...

My code is as follows:

protected void onListItemClick(ListView listView,         


        

Answer 1

You can use :

In first activity ( MainActivity page )

Intent i = new Intent(MainActivity.this,SecondActivity.class); 
i.putExtra("YourValueKey", yourData.getText().toString());

then you can get it from your second activity by :
In second activity ( SecondActivity page )

Intent intent = getIntent();
String YourtransferredData = intent.getExtras().getString("YourValueKey");

Answer 2

From the First Activity

Intent i=new Intent(getApplicationContext(),BookPractionerAppoinment.class);
i.putExtra("prac","test");
startActivity(i);

Getting values in Second ACT Activity

String prac=getIntent().getStringExtra("prac);

For Serialized objects:

Passing

Intent i=new Intent(getApplicationContext(),BookPractionerAppoinment.class);
 i.putExtra("prac",pract);
 startActivity(i);

Getting

pract= (Payload) getIntent().getSerializableExtra("prac");

Answer 3

String value = Integer.toString(getIntent().getExtras().getInt("bucketno"));

Answer 4

Use:

String value = getIntent().getExtras().get("key").toString();

getIntent().getExtras() will give you Boundle. get() method can be used to fetch the values.

Answer 5

In addition who has different sittuation

  double userDMH = Util.getInstance(TakeInfoOne.this).calculateBMH(userGender, kg, talll, currentAge, activityy);
                        Intent intentTogeneral = new Intent(TakeInfoOne.this, TakeInfoTwo.class);
                        intentTogeneral.putExtra("user_current_age",userDMH );
                        startActivity(intentTogeneral);

If you put other primitives like double , boolean , int just dont forget to type correct format while geting the value in secont Activity

Bundle extras = getIntent().getExtras();
    if (extras != null) {
        double value =  extras.getDouble("user_current_age");
        txt_metabolism.setText(""+value);
    }

Here with extras.getDouble() type your concerned value type like

extras.getInt("user_current_age");
extras.getBoolean("user_current_age");
 extras.getString("user_current_age");

Answer 6

Replace this,

String value = getIntent().getExtras().getString("bucketno");

with

int value = getIntent().getExtras().getInt("bucketno");

You are trying to pass int value but retrieving String Data. That's why you are getting the nullpointerException.
