Check if MenuItem is null

Issue

I am trying to make a clean checkbox code in android but makes error if i just press the button and havent checked the checkbox this is the code of cleaning the checkbox:

public void fillDefaultDCN(MenuItem item){
int id = item.getItemId();
if(id == R.id.checkIt){
item.setChecked(false);
checkDCN = false;
}
}

And this is the code i have put on the RESET button

fillDefaultDCN(checkbox);

The checkbox is a declaration:

public MenuItem checkbox;

Apparently the Item.getItemId is null when the checbox is not checked and makes error.

Solution

Try this

public void fillDefaultDCN(MenuItem item){
if(checkbox == null){
//something
}else{
int id = item.getItemId();
if(id == R.id.checkIt){
item.setChecked(false);
checkDCN = false;
}
}
