Android - Passing An Object To Another Activity

I am utilizing the follow class, which I have as an object: http://pastebin.com/rKmtbDgF And I am trying to pass it across using: Intent booklist = new Intent(getBaseContext(), Boo

Solution 1:

Easiest Way to do this is to implement Serializeable ..

import java.io.Serializable;

@SuppressWarnings("serial") 
publicclassStudentimplementsSerializable {

publicStudent(int age, String name){
    this.age = age;
    this.name = name;
}

public int getAge() {
    return age;
}
publicvoidsetAge(int age) {
    this.age = age;
}
publicStringgetName() {
    returnthis.name;
}
publicvoidsetName(String name) {
    this.name = name;
}

private int age;
privateString name;

}

Sending object from Activity A to Activity B

Studentstudent=newStudent (18,"Zar E Ahmer");
Intenti=newIntent(this, B.class);
i.putExtra("studentObject", student);
startActivity(i);

Getting Object in Activity B.

Intenti= getIntent();
Studentstudent= (Student)i.getSerializableExtra("studentObject");

Solution 2:

go here, and paste your class structure.it will create parcelable class for you and then you can easily pass your object around activities.

Solution 3:

Try the following post.

How can I make my custom objects Parcelable?

The problem is that the ImageManager is not a parable Object. So that's giving the cast error. If the imageManager is yours you should make the class implement Pracabale like the url above sais.

EDIT:

Above should be the right way of doing Parceables, But in your case i really would say you shouldn't pass the ImageManager between different activities. Because the context that your using in the ImageManager class will be disposed.. And you'll certainly get an error.

So why don't you make a new instance of the class instead and only pass the Bitmap in to it (After transferring the bitmap and other not context related information with the bundle off course.)
