Using setImageDrawable dynamically to set image in an ImageView

Question

I am generating a string from database dynamically which has the same name of image in drawable folder.

Now I want to set that value for ImageView

Answer 1

If You cannot get Resources object like this in a class which is not an Activity, you have to add getContext() method for getResources() for example

ImageView image = (ImageView) v.findViewById(R.id.item_image);
int id = getContext().getResources().getIdentifier(imageName, "drawable", getContext().getPackageName());
image.setImageResource(id);

Answer 2

Try this,

int id = getResources().getIdentifier("yourpackagename:drawable/" + StringGenerated, null, null);

This will return the id of the drawable you want to access... then you can set the image in the imageview by doing the following

imageview.setImageResource(id);

Answer 3

You can try to use this code:

ImageView ImgView = (ImageView)findViewById(R.id.ImgView);
ImgView.setImageResource(R.drawable.myicon);

Answer 4

Drawable image = ImageOperations(context,ed.toString(),"image.jpg");
            ImageView imgView = new ImageView(context);
            imgView = (ImageView)findViewById(R.id.image1);
            imgView.setImageDrawable(image);

or

setImageDrawable(getResources().getDrawable(R.drawable.icon));

Answer 5

You can also use something like:

imageView.setImageDrawable(ActivityCompat.getDrawable(getContext(), R.drawable.generatedID));

or using Picasso:

Picasso.with(getContext()).load(R.drawable.generatedId).into(imageView);

Answer 6

As simple as this answer:

Drawable myDrawable = getResources().getDrawable(R.drawable.pic);
imageview.setImageDrawable(myDrawable);
