How to pass custom object in Bundle?

Question

I am trying to pass my own custom object into a bundle:

Bundle b = new Bundle();                 STMessage message = (STMessage)a.getAdapter().getItem(position);                 b.putObject("message",message); 

I get the error:

The method putObject(String, Object) is undefined for the type Bundle 

Answer 1

One way is to have your custom object implement the Parcelable interface and use Bundle.putParcelable/Bundle.getParcelable

Model Class

package com.sam.bundleobjectpass;  import java.io.Serializable;  /**  * Created by Samir on 31.8.2016.  */ public class Model implements Serializable {     private String name;     private String surName;     private int age;      public Model(String name, String surName, int age) {         this.name = name;         this.surName = surName;         this.age = age;     }      public String getName() {         return name;     }           public String getSurName() {         return surName;     }       public int getAge() {         return age;     }   } 

MainActivity

public class MainActivity extends AppCompatActivity {      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);           Model model = new Model("Sam", "Sami",32);                  Intent i = new Intent(MainActivity.this, ReceiverActivity.class);         i.putExtra("Editing", model); // sending our object. In Kotlin is the same         startActivity(i);      } } 

ReceiverActivity

public class ReceiverActivity extends Activity {      TextView txt_name;     TextView txt_surname;     TextView txt_age;      @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.second);          txt_name = (TextView)findViewById(R.id.txt_name);         txt_surname = (TextView)findViewById(R.id.txt_surname);         txt_age = (TextView)findViewById(R.id.txt_age);         // receiving our object         Model model = (Model) getIntent().getSerializableExtra("Editing");          txt_name.setText(model.getName());         txt_surname.setText(model.getSurName());         txt_age.setText(""+model.getAge());       } } 

// Kotlin

val model: ProgramModel? = intent.getSerializableExtra("Editing") as ProgramModel?         model?.let { // means if not null or empty             txt_act_daily_topic.text = it.title         }
