从字符串获取android的id资源 [英] Get android's id resource from a string

问题描述

在我的Kotlin应用程序中，我有一些ImageViews(在 activity_main.xml 中):imageView_0，imageView_1，imageView_2和imageView_3.

In my Kotlin app I have some ImageViews (in activity_main.xml): imageView_0, imageView_1, imageView_2 and imageView_3.

如何从0到3循环访问视图?这是行不通的:

How can I access the view in a loop from 0 to 3? This won't work:

val imageView: ImageView = findViewById<ImageView>("R.id.imageView_" + index) as ImageView

推荐答案

for(i in 1..3){
  val id: int=getResources().getIdentifier("imageview_"+i, "id", 
  getPackageName())
  imageview[i]=findViewById(id) as ImageView
}

如果您在 xml ，imageview_1，imageview_2，imageview_3
