java - How do I create array of drawable automatically -


i have while loop create string array below

string[] imageid = {"r.drawable.img0","r.drawable.img1"};

but want store integer array

integer[] imageid = {r.drawable.img20,r.drawable.img1};

one way of doing without using reflection create mapping drawables have (since know drawables in resources @ compile time):

static final map<string, integer> mapping; static {     final map<string, integer> tempmapping = new hashmap<>();     tempmapping.put("r.drawable.img0", r.drawable.img20);     tempmapping.put("r.drawable.img1", r.drawable.img1);     tempmapping.put([your other drawables]);     mapping = collections.unmodifiablemap(valuesbyname); }

after that, depending on app's logic, construct array of drawables' names, , convert array of drawables' ids using map.
