下面的函数从共享偏好,权重和高度中获取两个值,我使用它们来计算BMI,当我打印值的内容时,我得到我在sharedprefs中输入的值(这很好)但是当我运行时对它们进行除法运算,结果总是得到0 ..错误在哪里？

public int computeBMI(){
    SharedPreferences customSharedPreference = getSharedPreferences(
            "myCustomSharedPrefs", Activity.MODE_PRIVATE);

    String Height = customSharedPreference.getString("heightpref", "");
    String Weight = customSharedPreference.getString("weightpref", "");

    int weight = Integer.parseInt(Weight);
    int height = Integer.parseInt(Height);
    Toast.makeText(CalculationsActivity.this, Height+" "+ Weight , Toast.LENGTH_LONG).show();

    int bmi = weight/(height*height);
    return bmi;

}
