从字符串中读取字符并在textviews中设置它

Question

我是Android和java编程的新手。我想逐字符地读取我的字符串..以这种方式将第一个字符设置为某个文本视图，将第二个字符设置为其他文本视图..我的字符串不要包含两个以上的字符。我尝试了charAT（）方法，但没有结果请查看代码。

 new Handler().postDelayed(new Runnable() {
   @Override
   public void run() {

     val1 = Integer.parseInt(String.valueOf(quotient3.getText()));
     val2 = Integer.parseInt(String.valueOf(divisor.getText()));
     result = val1 * val2;

     val = Integer.toString(result);

     if(val.length()==1){
       aftersub2dividend2.setText(val.charAt(0)); //here is the issue
       aftersub2dividend1.setText(val.charAt(1)); //here is the issue
     }
     else {
       aftersub2dividend1.setText(val.charAt(0)); //here is the issue
       aftersub2dividend2.setText(val.charAt(1)); //here is the issue
     }
   }
  },3000);

Answer 1

aftersub2dividend1.setText(String.valueOf(val.charAt(0)));
