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 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 pass an object from one activity to another on Android
One option could be letting your custom class implement the Serializable
interface and then you can pass object instances in the intent extra using the putExtra(Serializable..)
variant of the Intent#putExtra()
method.
Actual Code:
In Your Custom Model/Object Class:
public class YourClass implements Serializable {
At other class where using the Custom Model/Class:
//To pass:
intent.putExtra("KEY_NAME", myObject);
myObject is of type "YourClass".
Then to retrieve from another activity, use getSerializableExtra
get the object using same Key name. And typecast to YourClass is needed:
// To retrieve object in second Activity
myObject = (YourClass) getIntent().getSerializableExtra("KEY_NAME");
Note: Make sure each nested class of your main custom class has implemented Serializable interface to avoid any serialization exceptions. For example:
class MainClass implements Serializable {
public MainClass() {}
public static class ChildClass implements Serializable {
public ChildClass() {}
}
}
