[Solved] How do I get extra data from intent on Android?

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());

Solution #1:

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");

Solution #2:

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

//  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);
//  How to get these values in another class
//  Class B
    Intent i= getIntent();
//  if you log here i than you will get the value of i i.e. john

Set Data

String value = "Hello World!";
Intent intent = new Intent(getApplicationContext(), NewActivity.class);
intent.putExtra("sample_name", value);

Get Data

String value;
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
    value = bundle.getString("sample_name");

Solution #5:

Instead of initializing another new Intent to receive the data, just do this:

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

Solution #6:

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());

In the fragment, you just need to call getActivity() first,

The second page extends Fragment:

String receive = getActivity().getIntent().getExtras().getString("name");

Solution #7:

If you are trying to get extra data in fragments then you can try using:

Place data using:

Bundle args = new Bundle();

Get data using:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

Solution #8:

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);

Solution #9:

Put data by intent:

Intent intent = new Intent(mContext, HomeWorkReportActivity.class);
intent.putExtra("subjectName", "Maths");
intent.putExtra("instituteId", 22);

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.

Solution #10:


First Activity

val intent = Intent(this,
intent.putExtra("key", "value")

Second Activity

val value = getIntent().getStringExtra("key")


Always put keys in constant file for more managed way.

Solution #11:

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).

Solution #12:

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());

In SecondActivity:

    try {
        Intent intent = getIntent();

        String uid = intent.getStringExtra("uid");
        String pwd = intent.getStringExtra("pwd");

    } catch (Exception e) {
        Log.e("getStringExtra_EX", e + "");
Respondent: sam

Solution #13:

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());

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.

Solution #14:

You can also do like this
// put value in intent

    Intent in = new Intent(MainActivity.this, Booked.class);
    in.putExtra("filter", "Booked");

// get value from intent

    Intent intent = getIntent();
    Bundle bundle = intent.getExtras();
    String filter = bundle.getString("filter");

Getting Different Types of Extra from Intent

To access data from Intent you should know two things.

  • KEY
  • DataType of your data.

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.

Example to retrieve String in your Activity from Intent

String profileName = getIntent().getStringExtra("SomeKey");

List of different variants of methods for different dataType

You can see the list of available methods in Official Documentation of Intent.

Solution #16:

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

 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
            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
