How to pass a String array value from one activity to another Activity in android?

Question

I am having two activities in my application. I want to pass tha array of String from one activity to another.. How to pass this values from activity to activity?

Answer 1

You can consider using Intent.getStringArrayExtra

In the first activity:

Intent intent = new Intent(context, NewActivity.class);
intent.putExtra("string-array", stringArray);
context.startActivity(intent);

and in the second one:

Intent intent = getIntent();
String [] stringArray = intent.getStringArrayExtra("string-array");

Answer 2

Here's some reading: http://www.vogella.de/articles/AndroidIntent/article.html#overview_accessdata go to section 2.1.

Also, How to pass ArrayList using putStringArrayListExtra() should explain something similar.

Answer 3

just serialize it and set it in the extras of the intent (of activity) you wanna open.
You will receive it in the onCreate() of that activity.
Convert it to array again.

Answer 4

In Activity One, write this code to create an array and pass it to another activity:

String[] array1={"asd","fgh","dcf","dg","ere","dsf"};
Intent i=new Intent(MainActivity.this,Main2Activity.class);
i.putExtra("key",array1);
startActivity(i);

In Second Activity, write this to retrieve your array

String[] array = getIntent().getStringArrayExtra("key");
