for循环,遍历为buttons的数组

做了个按键的项目，有十六个按键，0-9，a，b,c,d,*,#

开始一个个设置按键麻烦死了，后来建了一个数组直接节省了一堆代码

Button button0,button1, button2, button3;
Button button4, button5,button6, button7;
Button button8, button9,buttonx, buttony;
Button buttona, buttonb, buttonc,buttond;

Integer[] id= new Integer[]{R.id.button0,R.id.button1,R.id.button2,R.id.button3,
R.id.button4,R.id.button5,R.id.button6,R.id.button7,
R.id.button8,R.id.button9,R.id.buttona,R.id.buttonb,
R.id.buttonc,R.id.buttond,R.id.buttonx,R.id.buttony};
Button[] buttons=new Button[]{button0,button1, button2, button3,
button4, button5,button6, button7,
button8, button9,buttona, buttonb,
buttonc, buttond,buttonx, buttony};

for(int x=0;x<=15;x++){
buttons[x]=(Button)findViewById(id[x]);
}

tb_nodeStatus = nodeStatusDAO.find(PubilcDefine.KEY);
keyzhi = (int) tb_nodeStatus.getvalue1();
nodename = tb_nodeStatus.getnodename();
if(keyzhi==0xff){

}
else{
for(int i=0;i<=15;i++){
if(keyzhi==i){
if(key[i]==1){
buttons[i].setBackgroundColor(Color.RED);
key[i]=0;
keyzhi=0xff;
Tb_nodeStatus tb_nodeStatus2 = new Tb_nodeStatus(PubilcDefine.KEY, nodename, keyzhi, 0);
nodeStatusDAO.update(tb_nodeStatus2);
}else{
buttons[i].setBackgroundColor(Color.rgb(211, 211, 211));
key[i] = 1;
keyzhi = 0xff;
Tb_nodeStatus tb_nodeStatus2 = new Tb_nodeStatus(PubilcDefine.KEY, nodename, keyzhi, 0);
nodeStatusDAO.update(tb_nodeStatus2);
}
}
}

}

很轻松的写完本来应该写的一大段代码嘿嘿
