问题描述
该计划给出了我的每一个值HTM的一个值。我想通过反复pressing计算按钮来依次显示每个值。我想,当我preSS它改变到i = 1,并显示由此计算的数值按钮它对于i = 0显示值,然后。
我知道我的问题是有点模糊,但你的帮助将是非常美联社preciated ..

据我从你的问题明白了,你不应该用你的for循环
为(i = 0; I< = 11;我++)
有关循环删除这一点,声明一个变量,并设置我来了,退出时的onClick增加你的变量。
私人INT计数器= 0;公共无效的onClick(视图v){
INT I =计数器;
//一切还在继续,只是删除循环
angle.setText(测试版=+ ANG);
反++;
如果(反== 12)计数器= 0; //你的阵列是固定的,所以我们义无反顾
}
This program gives one value of Htm for each value of i. I want to display each value in turn by repeatedly pressing the calculate button. I want it to display the values for i=0 and then when i press the button it changes to i=1 and displays the values thus calculated.I know my question is a bit vague, but your help will be really appreciated..Regards

As far as I understand from your question, you should not use your for loop
for (i = 0; i <= 11; i++)
Remove this for loop, Declare a variable, and set "i" to it, when exiting onClick increase your variable.
private int counter=0;
public void onClick(View v) {
int i=counter;
//everything continues, just remove the for loop
angle.setText("Beta =" + ang);
counter++;
if(counter==12) counter=0;//your arrays are fixed, so we are turning back
}
