How to pass values from a Class to Activity - Android

Question

I have a newbie question about Class/Task/Activity. I\'m coming from C so I don\'t know if it\'s a good approach to do what I need.

I\'ve created a class:

Answer 1

In android 4 option to do this

• In android you can send data through Intent or Intent followed by Bundle.Like Intent i = new Intent(current_class.this, linked_class.class); i.putextra("Key", value);

And get the value(suppose string value) in another class like:

 String value = getIntent.getExtra("String key which you used when send value");

• option 2

  class A{

  public static String _utfValue = "";

  void sendValue(){ _utfValue = "some value"; } }

And fetch this value in your java class like:

String value = A._utfValue ;

• You can use SharedPreference to save the value and get it from other class.
• You can use a static method with some return value and fetch the method in your java class through class name.
