float NormValue = value*80 ;
float color = Color.argb(0xFF, NormValue, 0, 0);
This is a part of my code. This variable (NormValue) stores the result in float . But in second line i cannot use this variable since it has to be converted to int. How can i do it. Any help?
Try this..
No need to typecast float to int just use Math.round()
float NormValue = value*80 ;
float color = Color.argb(0xFF, Math.round(NormValue), 0, 0);
Depends on the scale of your NormValue.
Normally, a simple type cast would do:
(int)NormValue
But you may want to scale the NormValue to the range 0..255 first since Color.argb() just uses the least significant 8 bits of the int values passed in.
Try this.
Convert it to string
String.valueOf(value);
and then convert it to integer
Integer.valueOf(string);
You can also try casting it to int
Int i = (int) your_float_value
Try this:
float NormValue = value*80 ;
int temp = (int)NormValue;
float color = Color.argb(0xFF, temp, 0, 0);
Android is java, right? You can simply cast it to int like this.
float f=0.2;
int i;
i = (int)f;
You really need to use float in the first place?
You have two options:
1. Use casting int normInt = (int)NormValue; but here you have to be prepared that you will loose the decimal points. eg: 8.61 will be 8
2. The second way to first round the NormValue then use casting.
You can search in this post, your solution is there: Java: (int)(float)Float.valueOf(s) or Float.valueOf(s).toInt()
