Passing Data from One Activity to Another Using Bundle - Not Displaying in Second Activity

Passing data from one activity to another using bundle - not displaying in second activity

Two ways you can send the data. This is how you are sending it at the moment. And there is nothing wrong with it.

//Create the bundle
Bundle bundle = new Bundle();
//Add your data from getFactualResults method to bundle
bundle.putString("VENUE_NAME", venueName);
//Add the bundle to the intent
i.putExtras(bundle);
startActivity(i);

In you code (second Activity) however, you are referring to the key in the Bundle as MainActivity.VENUE_NAME but nothing in the code suggests that you have a class that returns the value as the actual key name send with the Bundle. Change your code in the second Activity to this:

Bundle bundle = getIntent().getExtras();

//Extract the data…
String venName = bundle.getString("VENUE_NAME");        

//Create the text view
TextView textView = new TextView(this);
textView.setTextSize(40);
textView.setText(venName);

You can check in your second Activity if the Bundle contains the key using this and you will know that the key is not present in the Bundle. The correction above, however, will get it working for you.

if (bundle.containsKey(MainActivity.VENUE_NAME))    {
    ....
}

Why does it not pass data when I pass bundle from one activity to another in android?

Your code is incomprehensible:

1) what are you doing? setContentView(R.layout.datalayout);

2) What is data in data.getText().toString();

If you see the toast with no text in it that means that dataToInclude is either null or empty.
So focus to check data1 and data2 variables.


Edit: When you click on text the listener is executed immediately:

the new layout is shown with empty EditTexts, their empty strings are stored in data1 and data2 and you open the new activity with empty strings in the bundle.

unable to send values from one activity to other in Android

try this:

public void rsa_key(String s){
        Intent intent = new Intent(getBaseContext(), SomeClass.class);

        //String hello=null;
        intent.putExtras("id", txId);
        intent.putExtras("cardamt", cardAmount);
        intent.putExtras("cardconv", cardConvFee);

        startActivity(intent);

    }

in your second activity onCreate method

Bundle bundle = getIntent().getExtras();
String txId = bundle.getString("id");
        String cardConvFee = bundle.getString("cardconv");
        String cardAmount = bundle.getString("cardamt");

getting error when passing data from one activity to another activity

You made mistake here

startActivity(intent);

You put intent value in intent and start activity is intent1. So please pass intent1 instead of intent

startActivity(intent1);// pass this intent1

Use this code

                            Intent intent1 = new Intent(Name.this, Signup.class);
                            intent1.putExtra("userId", userId);
                            intent1.putExtra("token",token);
                            startActivity(intent1);
                            Log.e(TAG, "token: " + token);
                            Log.e(TAG, "userId: " + userId);

                            Toast.makeText(getApplicationContext(), "User successfully registered. Try login now!", Toast.LENGTH_LONG).show();
                            startActivity(intent1);

Android send data from activity to activity using bundle

in SendAnswerToServer Activity:

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    Bundle bundle = this.getIntent().getExtras();  

    if(bundle !=null)
    {
            //ObtainBundleData in the object 
      String strdata = bundle.getString("time"); 
       //Do something here if data  received
     }
     else
     {
       //Do something here if data not received
     }

How do I pass data between Activities in Android application?

The easiest way to do this would be to pass the session id to the signout activity in the Intent you're using to start the activity:

Intent intent = new Intent(getBaseContext(), SignoutActivity.class);
intent.putExtra("EXTRA_SESSION_ID", sessionId);
startActivity(intent);

Access that intent on the next activity:

String sessionId = getIntent().getStringExtra("EXTRA_SESSION_ID");

The docs for Intents has more information (look at the section titled "Extras").
