How to pass data from one activity to another activity by using intents?

Question

Here i wrote a code to pass data from one activity to another activity by using intents.. Please let me know if i need to do any corrections over here in my code.

   OnClickListener buttonListener = new OnClickListener() {

    @Override
    public void onClick(View arg0) {

        Intent nextIntent = new Intent(getApplicationContext(), SecondActivity.class);
        nextIntent.putExtra("firstname", "Siva");
        nextIntent.putExtra("Secondname", "Kumar");
        startActivity(nextIntent);


        Toast.makeText(getApplicationContext(),"SignIn Button Clicked", Toast.LENGTH_SHORT).show();
    }
};

Second Activity:

OnClickListener backListener = new OnClickListener() {

    @Override
    public void onClick(View v) {

        Intent backIntent = new Intent(getApplicationContext(), MainActivity.class);
        Intent receivedIntent = getIntent();
        Bundle bundleData = receivedIntent.getExtras();
        bundleData.getString("firstname");
        bundleData.getString("secondname");
        startActivity(backIntent);
    }
};

Make correction for your "Secondname" in your Second Activity. — Piyush, Jan 06 '14 at 08:08

You should try like this

pass data to SecondActivity

Intent nextIntent = new Intent(getApplicationContext(), SecondActivity.class);
nextIntent.putExtra("firstname", "Siva");
nextIntent.putExtra("Secondname", "Kumar");
startActivity(nextIntent);

get data inside SecondActivity

Intent receivedIntent = getIntent();
String firstname=receivedIntent.getStringExtra("firstname");
String secondname=receivedIntent.getStringExtra("Secondname");

EDIT

SecondActivity.jaja

public class SecondActivity extends Activity {



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);
    Intent receivedIntent = getIntent();
    String firstname=receivedIntent.getStringExtra("firstname");
    String secondname=receivedIntent.getStringExtra("Secondname");

    TextView txtFirst=(TextView)findViewById(R.id.text1);
    txtFirst.setText(firstname);
    TextView txtSecond=(TextView)findViewById(R.id.text2);
    txtSecond.setText(secondname);
    Button back=(Button)findViewById(R.id.backbutton);
    back.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
        finish();


        }
    });

}

}

Not working. Please look in to this once again. – user3164399 Jan 06 '14 at 10:42
It is working but I am not able to see the passed values in the second Activity. – user3164399 Jan 06 '14 at 10:56
display using Log or toast `Toast.makeText(SecondActivity.this, firstname,Toast.LENTH_LONG).show();` – Ketan Ahir Jan 06 '14 at 10:58
Dear Ketan, I already did that by using Toast and i am successful on that. I want to display as a text on the second activity. – user3164399 Jan 06 '14 at 11:06
It means you are getting value in SecondActivity..right ? – Ketan Ahir Jan 06 '14 at 11:07
I am getting redirected to second activity. But not able to display the text. – user3164399 Jan 06 '14 at 11:12
post your secondactivity code – Ketan Ahir Jan 06 '14 at 11:14
'OnClickListener backListener = new OnClickListener() { @Override public void onClick(View v) { Intent backIntent = new Intent(getApplicationContext(), MainActivity.class); Intent receivedIntent = getIntent(); Bundle bundleData = receivedIntent.getExtras(); bundleData.getString("firstname"); bundleData.getString("secondname"); startActivity(backIntent); } };' – user3164399 Jan 06 '14 at 11:20
why are you getting value in clicklistener. get value in oncreate method and display. – Ketan Ahir Jan 06 '14 at 11:23
Then How can i go back to my first activity..?? Please Don't mind i am just a beginner. I need your help... – user3164399 Jan 06 '14 at 11:29
whenever you want to go back just call `finish()` method. – Ketan Ahir Jan 06 '14 at 11:30
Please post the code of your version – user3164399 Jan 06 '14 at 11:50
try updated answer and make required changes. – Ketan Ahir Jan 06 '14 at 11:57

Use some String variables like below,

OnClickListener backListener = new OnClickListener() {

    @Override
    public void onClick(View v) {

        Intent backIntent = new Intent(getApplicationContext(), MainActivity.class);
        Intent receivedIntent = getIntent();
        String firstName = getIntent().getStringExtra("firstname");
        String secondName = getIntent().getStringExtra("Secondname");
        startActivity(backIntent);
    }
};

Now your two String variables firstName and secondName contains the information you required.

Sorry it's not worked... Please suggest me in your own coding style for simple data passing using intents... Thanks – user3164399 Jan 06 '14 at 08:13
@user3164399, I have updated my answer, please check it now. In "Secondname". your "S" is capital and in receiving part it is small. change it and check it again. – Vigbyor Jan 06 '14 at 08:17
I made the changes as you suggested... It is working but I am not able to see the passed values in the second intent. – user3164399 Jan 06 '14 at 10:49
@user3164399, sorry there was spelling mistake in secondname, I have updated it, please try again. – Vigbyor Jan 06 '14 at 10:51
Still facing the same... Is there any other reason other than code..??? – user3164399 Jan 06 '14 at 10:57
sure, can you upload your code in the question ? – Vigbyor Jan 06 '14 at 10:58
