Question

I have passed my resource ID through intent to another class. I then retrieve the extra from the intent and store it in an int.

Now I want to get that int to convert into a view or something so that I can use getTag()? I tried assigning it to an ImageView but kept getting NullPointer

Passed:

             int resourceId = v.getId(); 

             Intent intent = new Intent(FetchMenu.this,FetchContent.class);
             intent.putExtra("ResourceId",resourceId);  
             startActivity(intent);       

Received:

             int id;

             Intent callingIntent = getIntent();
             int getView= callingIntent.getIntExtra("ResourceId", 1); 
             id = getView;

This prints to logcat:

System.out.println("Resource ID: " + id);

Logcat:"Resource ID: 2131099660"

This is giving me NullPointer:

             View v = (View)findViewById(id);                

             String str=(String) v.getTag();

             System.out.println("Tag : " + str);

Thanks

Views are from the type int. So you can put the layout as Extras in an Intent:

final Intent intent = new Intent(this,Activity2.class);
intent.putExtra("layout",R.layout.mylayout);
startActivity(intent);

And then in your Activity2:

Bundle bundle = getIntent().getExtras();
final int iLayout = bundle.getInt("layout");
setContentView(iLayout);
