Java 中的除法总是导致零 (0)?
下面的函数从共享首选项中获取两个值,体重和身高,我用它们来计算BMI,当我打印值的内容时,我得到我在shareprefs中输入的值(这很好),但是当我对它们运行除法运算时,我总是得到0作为结果。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;
}
