How Can I Display Values From Edittext User Input?

I have a SharedPreferences that saves EditText input from one activity and displays the String value in another activity. When I enter an input into the EditText fields and press

Solution 1:

I think part of what you're looking for is to put your CustomStoreActivity code in onResume instead of onCreate. Whatever code you move into onResume will occur whenever the CustomStoreActivity is brought to the front (including when it is first created).

Another alternative, assuming that CustomStoreActivity is used to launch the Activity that contains the EditTexts, is to use startActivityForResult and pass the data back in the result Intent instead of using the SharedPreferences. Here is a simple example (though note that the setResult call in this example is passed null where you would want to pass in an Intent, as documented here in the Android docs).

It also seems like you're trying to use your second Activity like a dialog box with editable fields. If that's the case, yet another alternative is to actually use a variant of the Dialog class within your CustomStoreActivity class instead of creating another Activity to act like one. See the Android doc for dialogs.

Solution 2:

I'm not sure I really understand your question but are you trying to update the TextView of a different Activity from the one you are in? In which case I don't think this can be done and you should use Intents to pass the data to the activity
