How do I get a variable in another activity?

Question

How do I access variable value in another activity. In my example I have a string variable item which value is spinner selected value. How can I access this variable in ano

Answer 1

You can declare them as static variables and then in your other class you may access them like Activity1.stringName.

public static String stringName; 

stringName = .. // value from Spinner

Then, in all the other Activities, you can access them as YourMainActivty.stringName.

Answer 2

If you didn't want to use a global variable you could always create a method in your activity to return your string.

public static String getMyString(){
    return item;
}

Then in your current activity you could call:

String myValue = LoginScreen.getMyString();

Answer 3

Try this.

Step 1: Create a static Bundle object in Application class.( ApplicationClass.java)

     public static Bundle mMyAppsBundle = new Bundle():

Step 2:

Set key values pair in that bundle from anywhere. like this:

   ApplicationClass.mMyAppsBundle.putString("key","value");

Step 3:

Now you can get these values from anywhere like this way:

   String str = ApplicationClass.mMyAppsBundle.getString("key");

Apply null check before using bundle objects for safety points of view.
