Question

I have two Intent s and two Activity s.

I have in the first Intent an EditText .

I want to use the text in the EditText in the second intent and pass to the second intent

Intent myIntent = new Intent(mycurentActivity.this, secondActivity.class);
startActivity(myIntent); 

Thank you in advance

Answer 1

Your looking for Intent#putExtra(String, String).

Here is an example:

Intent myIntent = new Intent(mycurentActivity.this, secondActivity.class);
myIntent.putExtra("key", myEditText.Text.toString();
startActivity(myIntent); 

When your receiving the Intent you can extract it again:

String text = myIntent.getStringExtra("key");

(http://developer.android.com/reference/android/content/Intent.html#getStringExtra(java.lang.String))

in the First activity

//...
final static int EDIT=0;
//...(action trigger)
public void onClick(View v) {
    // TODO Auto-generated method stub

    Intent intent;
    intent = new Intent().setClass(mycurentActivity.this, secondActivity.class);
    startActivityForResult(intent, EDIT);
}
//...

and later in the First activity

//...
protected void onActivityResult(int requestCode, int resultCode, Intent data){
    switch(requestCode){
        case EDIT:
            if(resultCode == RESULT_OK){
            String text = data.getStringExtra("key");
            //do whatever with the text...
        }else if(resultCode == RESULT_CANCELED){
        }
    break;
    }
}
//...

and second activity

//...
Intent intent = new Intent().setClass(secondActivity.this, mycurentActivity.class);
intent.putExtra("key", myEditText.getText().toString);
setResult(RESULT_OK, intent);
finish();
//...

First Activity

 Intent myIntent = new Intent(rechercheCP.this, XMLParsing.class);
                    myIntent.putExtra("key", autoComplete.getText().toString());
                    startActivity(myIntent);

Second Activity

TextView a;
String text = myIntent.getStringExtra("key");
a = new TextView(this);
    a.setText(text);
    layout.addView(a);
