Java中的除法总是导致零(0)吗?
下面的函数从sharedpreferences中获取两个值,即weight和height,我用它们来计算BMI,当我打印这些值的内容时,我得到了我在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后,结果总是为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;}
