Question

I programmatically am creating buttons as depending on certain factors their will either be 3 or 4 buttons.

In some instances I would like to create all of the buttons but disable them all. At the moment the problem I have is that I cannot access the buttons from outside of this loop

    if (4val != null && 4val.length() > 0){
        Button b4 = new Button(this);
        b4.setText(answer4val);
        b4.setTextSize(18);
        layout.addView(b4, layoutParams);
        b4.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                reason(4);
            }
        });
    }

I would like to disable / enable all of the buttons outside of these if statements. Is this possible?

Answer 1

Declare them in a wider scopre (maybe as class members):

// in the class scope
Button b4 = null;

// in the method scope
if (4val != null && 4val.length() > 0){
    b4 = new Button(this);
    b4.setText(answer4val);
    b4.setTextSize(18);
    layout.addView(b4, layoutParams);
    b4.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            reason(4);
        }
    });
}
