Android: Layout Object With Integer In Id Cannot Be Referenced

I'm trying to set the images of some ImageButtons in my layout programmatically. To do so, I named my ImageButtons ic_1 to ic_5. During my initialization method, I want to loop th

Solution 1:

It might not be exactly what you were trying to do, but if you are only dealing with 5 buttons, you could always just declare a static array of the the Button Id's and loop through them.

Something like:

privatestaticfinalint[] buttons =
     {R.id.ic_1, R.id.ic_2, R.id.ic_3, R.id.ic_4, R.id.ic_5};

@OverridepublicvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainscreen);
    setMenuImage();
    initMainScreen();
}

publicvoidinitMainScreen() {
    if (standard == false) {
        retrieveLinks();
        intsize= mso.getHome().getIcon().size();

        if (size > 0) {
            for (inti=1; i < 2; i++) {

                Stringbuttype= mso.getHome().getIcon().get(i)
                        .getIconName();
                System.out.println(buttype.toLowerCase());
                inttypeID= getResources().getIdentifier(
                        buttype.toLowerCase(), "drawable", getPackageName());

                //Using the array of button id's directlyImageButtonbutton= (ImageButton) findViewById(buttons[i]);
                if(button != null){
                button.setImageResource(typeID);
                }else{
                    System.out.println(butid+" "+resID);
                }
            }
        }
    }
}

Solution 2:

you are starting with 0, that is the problem.

start the loop from i =1 ;

Solution 3:

You start your loop with i = 0 but your ic_1 starts with 1. Change the loop to start with 1, that should do the trick.
