How to Pass Values Between Activities on Android

How do I pass data between Activities in Android application?

The easiest way to do this would be to pass the session id to the signout activity in the Intent you're using to start the activity:

Intent intent = new Intent(getBaseContext(), SignoutActivity.class);
intent.putExtra("EXTRA_SESSION_ID", sessionId);
startActivity(intent);

Access that intent on the next activity:

String sessionId = getIntent().getStringExtra("EXTRA_SESSION_ID");

The docs for Intents has more information (look at the section titled "Extras").

Using intents to pass data between activities

Pass the data from Activity-1 to AndroidTabRes.. as below:

At sending activity...

Intent intent = new Intent(current.this, AndroidTabRestaurantDescSearchListView.class);
intent.putExtra("keyName","value");
startActivity(intent);

At AndroidTabRes.. activity...

  String data = getIntent().getExtras().getString("keyName");

Thus you can have data at receiving activity from sending activity...

And in your AndroidTabRestaurantDescSearchListView class, do this:

String value= getIntent().getStringExtra("keyName");

Intent intent = new Intent(this, RatingDescriptionSearchActivity.class);
intent.putExtra("keyName", value);
startActivity(intent);

Then in your RatingDescriptionSearchActivity class, do this:

 String data= getIntent().getStringExtra("keyName");

How to passing data between 3 activities (Android Studio)

In Activity 1:on click listener of insert button put this:

   Intent  i = new Intent(Activity1.this, Activity2.class);
   String name = input.gettext();
   i.putExtra("name",name);
   StartActivity(i);

above code will pass value from activity 1 to activity 2,i assume you are quite new to android development go through this link carefully to understand Intents and starting activity

Now in Activity2 get the values from intent

  String name=getIntent().getStringExtra("name");

name will have value passed from activity 1;

Now following same pattern you can pass value from activity 2 to activity 3

How to pass a value from one Activity to another in Android?

You can use Bundle to do the same in Android

Create the intent:

Intent i = new Intent(this, ActivityTwo.class);
AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete);
String getrec=textView.getText().toString();

//Create the bundle
Bundle bundle = new Bundle();

//Add your data to bundle
bundle.putString(“stuff”, getrec);

//Add the bundle to the intent
i.putExtras(bundle);

//Fire that second activity
startActivity(i);

Now in your second activity retrieve your data from the bundle:

//Get the bundle
Bundle bundle = getIntent().getExtras();

//Extract the data…
String stuff = bundle.getString(“stuff”); 

How to pass data between activities forward and backward, android, kotlin

you could use startactivityforresult and set a result intent which includes the data you want to pass back

how to pass values from different activities to another activity

You have to pass the values in the Intent from activity to activity until Activity D.

class ActivityA extends Activity {
   ...
   private void startActivityB(){
      Intent i = new Intent(this, ActivityB.class);
      i.putExtra("val1", 1);
      i.putExtra("val2", 1);
      i.putExtra("val3", 1);
      startActivity(i);
   }
}

In ActivityB you have to read the value passed from ActivityA and pass these values to ActivityC with the new ones:

class ActivityB extends Activity {
   ...
   private void startActivityC(){

      int val1 = getIntent().getIntExtra("val1", 0);
      int val2 = getIntent().getIntExtra("val2", 0);
      int val3 = getIntent().getIntExtra("val3", 0);

      Intent i = new Intent(this, ActivityC.class);
      i.putExtra("val1", val1);
      i.putExtra("val2", val2);
      i.putExtra("val3", val3);

      i.putExtra("val4", 5);
      i.putExtra("val5", 6);
      i.putExtra("val6", 7);

      startActivity(i);
   }
}

Do the same for ActivityC and in ActivityD read the values out. I hope you get the idea.

Btw. an optimization would be to pass the sum from Activity to Activity instead of the single values, if you know that Activity D should displays the sum.
