how can I access declared variables using counter, in a loop, like this:
declared variables:
Button square0, square1, square2, square3, square4, square5, square6,
square7, square8, temp;
accessing them with a loop like this:
for (int i = 0; i < 9; i++) {
(Button) ("square"+i).setBackgroundResource();
It is very easy...
Button[] btnArray = new Button[10];
//assign all squares to the array
btnArray[0] = square1;
for(Button btn : btnArray){
btn.setBackGroundResource();
}
or even better use a List like
List<Button> myBtnList = new ArrayList<Button>();
myBtnList.add(square1);
add till all buttons are added then use the for each loop as illustrated above.
As others have mentioned this is bad practice in any programming language. If you want to access a list of things (in your case Buttons), you should use a List or an Array.
Here is an example using an ArrayList of Buttons:
List<Button> buttonList = new ArrayList<Button>();
Button button1 = new Button();
Button button3 = new Button();
Button button2 = new Button();
buttonList.add(button1);
buttonList.add(button2);
buttonList.add(button3);
// How to get a button out
for(int i = 0; i < buttonList.size(); i++)
myButton = buttonList.get(i);
// Do something with myButton here.
}
