How to connect declarations and If statements?
I want to change multiple textView colors through a couple if statements. All of them have different ID's except for the last part of them that ends with "....Price". I have tried just pasting the if statements on all of them but the build fails.
i have made declarations like this.
textView1Price = ("+10.00")
textView2Price = ("-10.00")
textView3Price = ("0.00")
and the if statements like so.
if (colorID.text.startsWith("-")) {
colorID.setTextColor(Color.RED)
}
if (colorID.text.startsWith("+")) {
colorID.setTextColor(Color.GREEN)
}
if (colorID.text.startsWith("0.00")) {
colorID.text = "_"
colorID.setTextColor(Color.DKGRAY)
I am having trouble figuring out how to connect the declarations to the If statements. I have tried something like this with partial success but can't list more that one declaration.
val colorID = textView1Price
i have also tried to find a way to reference the
text.contains("Price")
but have not been able to. Any help is appreciated. Thanks for your time.
EDIT: Solution Follow up
//Declarations
//metal location A price
Price1 = ("+10.00")
//metal location B price
Price2 = ("-10.00")
//metal location C price
Price3 = ("0.00")

For the TextViews that have ids like textView?Price you can use the getIdentifier() method to get their integer ids in a loop and then apply the conditions, like this (for 9 TextViews):
(1..9).forEach {
val id = resources.getIdentifier("textView${it}Price", "id", packageName)
val tv = findViewById<TextView>(id)
if (tv.text.startsWith("-")) {
tv.setTextColor(Color.RED)
} else if (tv.text.startsWith("+")) {
tv.setTextColor(Color.GREEN)
} else if (tv.text.startsWith("0.00")) {
tv.text = "_"
tv.setTextColor(Color.DKGRAY)
}
}
For resources and packageName you may need to supply a valid Context like:
val id = context.resources.getIdentifier("textView${it}Price", "id", context.packageName)
if your code is not inside an activity.
For the other TextViews, if their ids have such a similarity, you can use the same method.

Thanks for commenting. I am fairly new to this. Could you elaborate a little more? For the (1..9).forEach what if i have no determined amount? The textView#Price example was for easy reference. The ID's of each only have Price as the commonfactor. Sorry for the inconvenience.

I assume that you have textviews liketextView1Price,textView2Price,.. if the last one's id is textView1000Price, you just have to change the range to (1..1000). If the ids have not such a similarity then this code won't work.

i think i can make this work. ill just have to comment over all the entries so i can keep track of the values. example NewYorkPrice =. will be changed to textView1Price with a comment above stating New York. Thanks for your help i apprciate it.
