Question

I think this is a simple problem, but can’t find an answer.
I got this piece of code:

 public void onButtonClick(View v) {

    Intent intent = new Intent();
    intent.setAction(android.content.Intent.ACTION_VIEW);
    File file = new File(root + "/Doppen/"+ "doppen.txt");
    intent.setDataAndType(Uri.fromFile(file), "text/*");
    startActivityForResult(intent, 1);                   
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, getIntent());
    if(resultCode==RESULT_OK && requestCode==1){
        System.out.println("RESULT :D");
    }
}

Got any idea what is wrong here?

I open a text file, but after the user tapped on “Save”, I want to call an other function.
How to do this automatically?
So how to check when user taps on “Save” or when the intent is done/finished?

EDIT 1:
I found a problem:
When I comment if(resultCode==RESULT_OK && requestCode==1){ then it does print the result when it is done, So I know where it goes wrong, now the why question :p

EDIT 2:

requestCode does prints “1”, so that is good. However, resultCode prints “0”, not good.

EDIT 3:

Found the answer, maybe also usefull for others.
After I pressed Save, I use the backbutton (of the phone) to get back to the app, but that gives a resultCode of “0”.

Answer 1

Call startActivityForResult() instead of startActivity(). When the activity completes, you’ll get a callback to your activity’s onActivityResult() method, where you can do what you need.

See the documentation for more information.

EDIT: RESULT_OK is a standard result code, but activities are free to return other values greater than or equal to RESULT_FIRST_USER. Zero is RESULT_CANCELED, which usually happens when someone whacks the Back button.
