Child Activity Not receiving data?

Question

I am learning android, so I was practising with a program in which I start a new activity with a button and then what ever text was input by the user in the edittext of the previous activity has to displayed in textview of the new started activity but when I pass the user input to the new activity, it doesn't display anything. What can be the problem here is the code: Lets say this parent activity:

        case R.id.Sfr:
        Intent data= new Intent(SendData.this, RecieveData.class);
        Bundle check = new Bundle();

        check.putString("UmerData", cheese);
        medt.setText(cheese);
        data.putExtras(check);
        startActivityForResult(data, 5); // It is used to return data from child activity
        break;

The child activity which should show the user input passed to it is:

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.recievedata);
    Initialize(); 
    Bundle got = getIntent().getExtras();

    rt1.setText(got.getString("UmerData"));

}

Why is this child activity not showing userinput which has been passed to it?

Why you're using `startActivityForResult` Do you think this is the one which is starting new Activity. — Praveenkumar, Aug 11 '12 at 12:12
it is for another button.That is when the child activity starts, the user selects some radiobutton and according to that the data is passed back to the parent child when ReturnData button is pressed in child activity. — Alfred James, Aug 11 '12 at 12:17
Where is the `RecieveData.java` Is it in the same class `SendData.java`? — Praveenkumar, Aug 11 '12 at 12:26
no. RecieveData is the child class and SendData is parent class — Alfred James, Aug 11 '12 at 12:30
In your question's `onCreate()` code located in which class? — Praveenkumar, Aug 11 '12 at 12:32
oncreate is in child class and switch case thing is in parent class. — Alfred James, Aug 11 '12 at 12:34
Okay, now, these are in seperate class or both are in same class? — Praveenkumar, Aug 11 '12 at 12:36
Then, you've to use `startAcitivy` instead of `startActivityForResult` — Praveenkumar, Aug 11 '12 at 12:37
but then I would have to create a new intent and start new activity for passing data to parent class. This will be cumbersome. I am looking for a more intutive way. — Alfred James, Aug 11 '12 at 12:39

Try this -

case R.id.Sfr:
    Intent data= new Intent(SendData.this, RecieveData.class);
    Bundle check = new Bundle();
    check.putString("UmerData", cheese);
    medt.setText(cheese);
    data.putExtras(check);
    startActivity(data);
    break;

The child activity which should show the user input passed to it is:

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.recievedata);
    InitializeFuck();
    Bundle got = getIntent().getExtras();
    rt1.setText(got.getString("UmerData"));
}

write in first activity:-

Intent intent = new Intent(Activity1.this, Activity2.class);
intent.putStringExtra("keyForData", Value);
startActivity(intent);

write code in second Activity:-

Intent intent = Activity2.this.getIntent();
String data  =intent.getStringExtra("KeyForData");

1. Use Intent along with putExtra() for sending data to the Another Activity.

Eg:

   Intent i = new Intent(Your_Class.this, Desired_Class.class);

   i.putExtra("NameKey","name");

   startActivity(i);

2. Now use getIntent() on the receiving Activity to get the Starting Intent and then use getExtras() and getString() to get the String value associated with the key. We have getInt() etc too..

Eg:

   Intent intent = getIntent();

   String name = intent.getExtras().getString("NameKey");
