Question

首先，我在strings.xml文件中声明一个整数数组，并向它们添加3个项目然后我用

使用那些项目

private TextView Number12;
Number12=(TextView)findViewById(R.id.TextView01);
 Resources r = getResources();
        int[] bases = r.getIntArray(R.array.UserBases);
 for(i=0;i<bases[i];i++)
        {
            Number12.setText(bases[i]);
        }

我得到了例外，请给我一些解决方法如何显示数组

Answer 1

这里的问题是您将整数直接传递给setText方法。然后，它所调用的是setText(int)，它意味着接收资源ID，而不是值。所以，你唯一需要做的就是用这个整数创建一个String，这样调用的方法就是setText(String)（你可以做你想要的）：

private TextView Number12;
Number12=(TextView)findViewById(R.id.TextView01);
Resources r = getResources();
int[] bases = r.getIntArray(R.array.UserBases);
for(i=0;i<bases[i];i++){
      Number12.setText(Integer.toString(bases[i]));
}

Answer 2

在执行此操作之前，您是否设置了setContentView（）？因为在访问任何资源之前未设置setContentView（）时可能找不到资源错误。
