Is there a way to put a string variable in an imageview

Question

I have 5 Imageview namely Mycards_Slot1,Mycards_Slot2,Mycards_Slot3,Mycards_Slot4 and Mycards_Slot5 in a switch statement, can i use a String in setting the image resource in the imageview rather than retyping them and using them for other imageview.please help me on this thanks.

 switch(Frank_Share_counter) {
        case 1:
            MyCards_Slot1.setVisibility(View.VISIBLE);
            if (Frank_CS1==one){MyCards_Slot1.setImageResource(R.drawable.need_one);}//need(5)

Does this answer your question? [How to set an imageView's image from a string?](https://stackoverflow.com/questions/5254100/how-to-set-an-imageviews-image-from-a-string) — Mike M., May 02 '20 at 20:44
You can use the `Resources#getIdentifier()` method with your image names to get the corresponding resource IDs to use with `setImageResource()`. There are examples on the linked post above. — Mike M., May 02 '20 at 20:45
but that will mean getting the resource identifier for all imageview and images that will be more difficult than reusing the switch statement — franklyn omeben, May 02 '20 at 20:52
I'm not sure what you mean. Your question states "can i use a String in setting the image resource in the imageview". That's exactly what that will allow. — Mike M., May 02 '20 at 20:58
i meant the imageview, something like this string chageimg="MyCards" if (Frank_CS1==one){changeimg.setImageResource(R.drawable.need_one);} — franklyn omeben, May 02 '20 at 21:07
Oh, you want to find the `ImageView` itself with the `String`, yeah? Not the image? Well, you could do it with the same method; e.g., `String changeimg = "MyCards" + case_number;`, `int id = getResources().getIdentifier(changeimg, "id", getPackageName());`, `ImageView img = findViewById(id);`. However, that's unnecessarily roundabout. Instead, you could simply use an array or `List` of `ImageView`s; e.g., `ImageView[] imgs = new ImageView[5];`, `imgs[0] = MyCards_Slot1;`, etc. Then you can just use `imgs[case_number]`. — Mike M., May 02 '20 at 21:17

I am answering based on how I understand your question:

I assume you want to reference the drawables somehow, well you can set the resource id in an int

//reference them like this:
int need_one = R.drawable.need_one;
int need_two = R.drawable.need_one;
int need_three = R.drawable.need_three;
//.......
//complete the rest by yourself



//and just use them like this:


.........

if (Frank_CS1==one){MyCards_Slot1.setImageResource(need_one);}
if (Frank_CS1==two){MyCards_Slot1.setImageResource(need_two);}
if (Frank_CS1==three){MyCards_Slot1.setImageResource(need_three);}
.....
....
