      xiaomi.setData("Xiaomi",5.5,3,32,2.6,8.0);

Answer 1

你已經通過無效parameters.you可以通過固定的發送參數，如修復：

xiaomi.setData("Xiaomi",5.5f,3,32,2,8.0f); 

或更改函數簽名

String brand,float screensize,int ram,int memory,double processor,float androidversion 

並且還將變量更改爲 私人浮動屏幕尺寸;

private float androidversion; 
private int ram; 
private int memory; 
private double processor; 
private String brand;
