How can I send data from one activity (intent) to another?
I use this code to send data:
Intent i=new Intent(context,SendMessage.class);
i.putExtra("id", user.getUserAccountId()+"");
i.putExtra("name", user.getUserFullName());
context.startActivity(i);

In Kotlin and Jetpack Compose, use this:
val context = LocalContext.current
val intent = Intent(context, Activity2::class.java)
intent.putExtra("name", "John")
intent.putExtra("data2","aaaa")
context.startActivity(intent)
and in Activity2:
val intent = intent
val name = intent.getStringExtra("name")
val data2 = intent.getStringExtra("data2")
You can test by writing to the logcat:
`Log.d("A2", "Name $name $data2")`

A class to B class Data Sending
A class:
Intent in = new Intent(A.this, B.class);
in.putExtra("Name", ""+user.getUserFullName());
startActivity(in);
B class:
String name = getIntent().getStringExtra("Name");

Put data by intent:
Intent intent = new Intent(mContext, HomeWorkReportActivity.class);
intent.putExtra("subjectName", "Maths");
intent.putExtra("instituteId", 22);
mContext.startActivity(intent);
Get data by intent:
String subName = getIntent().getStringExtra("subjectName");
int insId = getIntent().getIntExtra("instituteId", 0);
If we use an integer value for the intent, we must set the second parameter to 0 in getIntent().getIntExtra("instituteId", 0)
. Otherwise, we do not use 0, and Android gives me an error.

If you are trying to get extra data in fragments then you can try using:
Place data using:
Bundle args = new Bundle();
args.putInt(DummySectionFragment.ARG_SECTION_NUMBER);
Get data using:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
getArguments().getInt(ARG_SECTION_NUMBER);
getArguments().getString(ARG_SECTION_STRING);
getArguments().getBoolean(ARG_SECTION_BOOL);
getArguments().getChar(ARG_SECTION_CHAR);
getArguments().getByte(ARG_SECTION_DATA);
}

You can get any type of extra data from intent, no matter if it's an object or string or any type of data.
Bundle extra = getIntent().getExtras();
if (extra != null){
String str1 = (String) extra.get("obj"); // get a object
String str2 = extra.getString("string"); //get a string
}
and the Shortest solution is:
Boolean isGranted = getIntent().getBooleanExtra("tag", false);

First, get the intent which has started your activity using the getIntent()
method:
Intent intent = getIntent();
If your extra data is represented as strings, then you can use intent.getStringExtra(String name)
method. In your case:
String id = intent.getStringExtra("id");
String name = intent.getStringExtra("name");

Pass the intent with value on First Activity:
Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("uid", uid.toString());
intent.putExtra("pwd", pwd.toString());
startActivity(intent);
Receive intent on second Activity;-
Intent intent = getIntent();
String user = intent.getStringExtra("uid");
String pass = intent.getStringExtra("pwd");
We use generally two method in intent to send the value and to get the value.
For sending the value we will use intent.putExtra("key", Value);
and during receive intent on another activity we will use intent.getStringExtra("key");
to get the intent data as String
or use some other available method to get other types of data (Integer
, Boolean
, etc.).
The key may be any keyword to identify the value means that what value you are sharing.
Hope it will work for you.

First Activity
val intent = Intent(this, SecondActivity::class.java)
intent.putExtra("key", "value")
startActivity(intent)
Second Activity
val value = getIntent().getStringExtra("key")
Suggestion
Always put keys in constant file for more managed way.
companion object {
val PUT_EXTRA_USER = "PUT_EXTRA_USER"
}

This is for adapter , for activity you just need to change mContext to your Activty name and for fragment you need to change mContext to getActivity()
public static ArrayList<String> tags_array ;// static array list if you want to pass array data
public void sendDataBundle(){
tags_array = new ArrayList();
tags_array.add("hashtag");//few array data
tags_array.add("selling");
tags_array.add("cityname");
tags_array.add("more");
tags_array.add("mobile");
tags_array.add("android");
tags_array.add("dress");
Intent su = new Intent(mContext, ViewItemActivity.class);
Bundle bun1 = new Bundle();
bun1.putString("product_title","My Product Titile");
bun1.putString("product_description", "My Product Discription");
bun1.putString("category", "Product Category");
bun1.putStringArrayList("hashtag", tags_array);//to pass array list
su.putExtras(bun1);
mContext.startActivity(su);
}

To access data from Intent you should know two things.
There are different methods in Intent class to extract different kind of data types. It looks like this
getIntent().XXXX(KEY) or intent.XXX(KEY);
So if you know the datatype of your varibale which you set in otherActivity you can use the respective method.
String profileName = getIntent().getStringExtra("SomeKey");
You can see the list of available methods in Official Documentation of Intent.

// How to send value using intent from one class to another class
// class A(which will send data)
Intent theIntent = new Intent(this, B.class);
theIntent.putExtra("name", john);
startActivity(theIntent);
// How to get these values in another class
// Class B
Intent i= getIntent();
i.getStringExtra("name");
// if you log here i than you will get the value of i i.e. john

We can do it by simple means:
In FirstActivity:
Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("uid", uid.toString());
intent.putExtra("pwd", pwd.toString());
startActivity(intent);
In SecondActivity:
try {
Intent intent = getIntent();
String uid = intent.getStringExtra("uid");
String pwd = intent.getStringExtra("pwd");
} catch (Exception e) {
e.printStackTrace();
Log.e("getStringExtra_EX", e + "");
}

You can also do like this
// put value in intent
Intent in = new Intent(MainActivity.this, Booked.class);
in.putExtra("filter", "Booked");
startActivity(in);
// get value from intent
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
String filter = bundle.getString("filter");

Just a suggestion:
Instead of using "id" or "name" in your i.putExtra("id".....), I would suggest, when it makes sense, using the current standard fields that can be used with putExtra(), i.e. Intent.EXTRA_something.
A full list can be found at Intent (Android Developers).

Instead of initializing another new Intent to receive the data, just do this:
String id = getIntent().getStringExtra("id");

If used in a FragmentActivity, try this:
The first page extends FragmentActivity
Intent Tabdetail = new Intent(getApplicationContext(), ReceivePage.class);
Tabdetail.putExtra("Marker", marker.getTitle().toString());
startActivity(Tabdetail);
In the fragment, you just need to call getActivity()
first,
The second page extends Fragment:
String receive = getActivity().getIntent().getExtras().getString("name");

String value = "Hello World!";
Intent intent = new Intent(getApplicationContext(), NewActivity.class);
intent.putExtra("sample_name", value);
startActivity(intent);
String value;
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
value = bundle.getString("sample_name");
}

In the receiving activity
Bundle extras = getIntent().getExtras();
String userName;
if (extras != null) {
userName = extras.getString("name");
// and get whatever type user account id is
}
