can write OnClickListener into parceable?

Question

Hello I have a trouble with OnClickListener

View.OnClickListener listener= new View.OnClickListener() 
{ 
@Override 
public void onClick(View view) 
   { 
     Toast.makeText(Conversations.this, "click on  MSG", 
           Toast.LENGTH_SHORT).show(); 
  } 
};

========================================================================

I Need put this listener into Fragment which will parceable. I not parceableing listener but after readvalue is null and when click app crasher because it's reference on null object.

now I need find some methods which can use for save and read object (View.OnClickListener) if parceable or something similar. Without this I need rebuild my project :(

Please Help me.

Thanks

I haven't have fragment in fragment I want all fragment put into "extra" and in other activity read from extra..

Intent i= new Intent(Conversations.this,MessagesSingleFragmentActivity.cla‌ss); i.putExtra("Fragment1", (Parcelable) recycleMessage); startActivity(i);

and in other activity have

Intent extras = getIntent(); Fragment fragment = (Fragment) extras.getParcelableExtra("Fragment1"); fm.beginTransaction().replace(R.id.fragment_container, fragment).commit();

No you cannot pass OnClickListener as Parcelable but , if you want to observe click from one fragment to another , then you have to implement the onclick in second fragment.

FragA.java:// who have onClickListener

Runnable run;

public void setClick(Runnable run){
   this.run = run;
}

view.setOnClickListener(new OnClickListener(){
    public void onClick(View v){
        // do something in onclick
        if(run!=null){run.run();}
    }
});

FragB.java:

((FragA)getParentFragment()).setClick(
       new Runnable() {
            @Override
            public void run() {
                // do something in other fragment
            }
        }
)

Updated:

If you want to perform something onClick of ActivityA on ActivityB , then EventBus are best options for that use Otto or EventBus by GreenBot

fragments don't have extra's , pass an argument in fragment – Zulqurnain Jutt Sep 25 '17 at 17:19
I pass fragment into extra when call activity. but when in fragment OnClickListener, I don't know how parceable it. – Parad0X Sep 25 '17 at 17:29

It is recommended to interact between fragments via Activity.. or more generally by interface which Activity conforms to.

One more thing: If you have common functionality in both fragments, maybe it is better to extract it to Activity?
