I am storing my project related images in drawable folder. Also I am storing the image names in string variable and dynamically I am trying to set those images to the imageview. But the image is not displaying. Please help me in this regard.

My Code: 

int res = getResources().getIdentifier(imagename, "drawable", this.getPackageName());
imageview= (ImageView)findViewById(R.id.imageView);
imageview.setImageResource(res);

In the above code "imagename" is the string variable which contains the image name.

Thanks in advance

Here is how to do it in Kotlin, inside a loop i:

Code reused from rfsbraz 's answer

    val uri = "@drawable/pic_top${i+1}"
    val imageResource = activity.resources.getIdentifier(uri, null, activity.packageName)

    val res = activity.getResources().getDrawable(imageResource)
    holder.view.imgDigit.setImageDrawable(res)

getDrawable() is deprecated. now you can use 

imageView.setImageDrawable(ContextCompat.getDrawable(this,R.drawable.msg_status_client_read))

ImageView imageView=findViewById(R.id.imageView)

if you have image in drawable folder then use

imageView.setImageResource(R.drawable.imageView)

if you have uri and want to display it in imageView then use

imageView.setImageUri("uri")

if you have bitmap and want to display it in imageView then use

imageView.setImageBitmap(bitmap)

note:- 1. imageView.setImageDrawable() is now deprecated in java 2. If image uri is from firebase or from any other online link then use

    Picasso.get()
    .load("uri")
    .into(imageView)

(https://github.com/square/picasso)

or use

Glide.with(context)
            .load("uri")
            .into(imageView)

int[] phptr=new int[5];

adding image pointer to array 

for(int lv=0;lv<3;lv++)
    {
        String id="a"+String.valueOf(lv+1);
        phptr[lv]= getResources().getIdentifier(id, "drawable", getPackageName());
    }

for(int loopvariable=0;loopvariable<3;loopvariable++) 
    {
        et[loopvariable] = findViewById(p[loopvariable]);
    }



for(int lv=0;lv<3;lv++)
    {
        et[k].setImageResource(phptr[k]);
    }
