Set visibility in Menu programmatically android

Question

So, that´s what I wanna know. How can I set the visibility of the menu programatically in Android?? This is how I have my menu:

public boolean onCreateOptionsMenu(Menu menu){     MenuInflater inflater = getMenuInflater();     inflater.inflate(R.menu.menu, menu);     return true; }  public boolean onOptionsItemSelected (MenuItem item){     switch (item.getItemId()){         case R.id.menuregistrar:             break;         case R.id.menusalir:             break;     }     return true; } 

But this code is not on the onCreate, so I don´t know how to set one item visible or invisible programmatically (in my case, I want the "menuregistrar" to be invisible once I have registered my application and forever.

Answer 1

Put this method in your Activity

public boolean onPrepareOptionsMenu(Menu menu) {     MenuItem register = menu.findItem(R.id.menuregistrar);           if(userRegistered)      {                    register.setVisible(false);     }     else     {         register.setVisible(true);     }     return true; } 

in shorter version you could write:

MenuItem register = menu.findItem(R.id.menuregistrar);       register.setVisible(!userRegistered);  //userRegistered is boolean, pointing if the user has registered or not. return true;

I would simplify Adil's solution even further with the following:

public boolean onPrepareOptionsMenu(Menu menu) {     MenuItem registrar = menu.findItem(R.id.menuregistrar);           registrar.setVisible(!isRegistered);     return true; }
