将 String.ValueOf 舍入到最接近的整数

Question

我正在尝试将 String.ValueOf 舍入到最接近的整数。知道如何将 String.valueOf(result) 得到最接近的整数。

public void onClick(View v) {
       double result =0;
       double result1 =0; 
       double a = Double.parseDouble(weightEntered.getText().toString().trim());
       double b = 2.2;
    if(v == button_convert)
    {
        if(lbs_kg.isChecked() == true) {
            result = (a / b);
            String str = String.valueOf(result);
            t1.setText(str);
        }

Answer 1

String str = String.valueOf(Math.round(result));
