Android-如何将按钮文本更改为arraylist项目

Question

I've got a grid of nine buttons and at the moment each one displays the numbers 1-9 as text and another button which will change the numbered buttons text to a different number from 1-9 when clicked. So basically it will appear to shuffle the buttons around but really its just changing the text. Or is it easier to just shuffle the buttons?

Can I put the numbers 1-9 into a string array to get the button text to change to an item from the array? And how do I make sure it uses all the numbers 1-9 once?

Answer 1

I think changing the Button text will be more easier and faster than realigning the buttons itself will be more complicated. to change the button text value use this. I think you know this.

Button yourButton = (Button)findViewById(R.id.yourbt);
    yourButton .setText(stringarrayvalue);

So use a ArrayList of buttons and change the value of buttons from it ..
