Using setImageDrawable dynamically to set image in an ImageView

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 using setImageDrawable(R.id.StringGenerated) dynamically.

Any Suggestions..

Now you can use setImageDrawable(Drawable drawable). example:

ImageView iState = findViewById(R.id.imageview_state);
if (isOk){
    iState.setImageDrawable(getDrawable(R.drawable.outline_ok));
}else{
    iState.setImageDrawable(getDrawable(R.drawable.outline_no));
}

enter image description here

From API 22 use:

Drawable myDrawable =  ResourcesCompat.getDrawable(getResources(), 
                        R.drawable.dos_red, null);

You can try to use this code:

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

All the answers posted do not apply today. For example, getDrawable() is deprecated. Here is an updated answer, cheers!

ContextCompat.getDrawable(mContext, drawable)

From documented method

public static final android.graphics.drawable.Drawable getDrawable(@NotNull android.content.Context context,
@android.support.annotation.DrawableRes int id

Construct a POJO.java class and create "constructor, getter & setter methods"

class POJO{
        public POJO(Drawable proImagePath) {
                setProductImagePath(proImagePath);
        }

        public Drawable getProductImagePath() {
                return productImagePath;
        }

        public void setProductImagePath(Drawable productImagePath) {
                this.productImagePath = productImagePath;
        }
}

Then setup the adapters through image drawable resources to CustomAdapter.java

    class CustomAdapter extends ArrayAdapter<POJO>{

       private ArrayList<POJO> cartList = new ArrayList<POJO>();
       public MyCartAdapter(Context context, int resource) {
          super(context, resource);
       }

       public MyCartAdapter(Context context, ArrayList<POJO> cartList) {
          super(context, 0, cartList);
          this.context = context;
          this.cartList = cartList;

       }

       @Override
       public View getView(int position, View convertView, ViewGroup parent) {
          /*
          *Here you can setup your layout and references.
          **/
          ImageView productImage = (ImageView) rootView.findViewById(R.id.cart_pro_image);
          productImage.setImageDrawable(POJO.getProductImagePath());
        }
    }

Then pass the references through ActivityClass.java

public class MyCartActivity extends AppCompatActivity{
       POJO pojo;
       CustomAdapter customAdapter;
       ArrayList<POJO> cartList = new ArrayList<POJO>();

       @Override
       protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.your_layout);

          customAdapter = new CustomAdapter(this, cartList);

          pojo = new POJO(getResources().getDrawable(R.drawable.help_green));

    }
}

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);

As simple as this answer:

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

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);

a piece of my project, everything works! )

@Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        final ModelSystemTraining modelSystemTraining = items.get(position);

int icon = context.getResources().getIdentifier(String.valueOf(modelSystemTraining.getItemIcon()), "drawable", context.getPackageName());

        final FragmentViewHolderSystem fragmentViewHolderSystem = (FragmentViewHolderSystem) holder;
        final View itemView = fragmentViewHolderSystem.itemView;
//                Set Icon
fragmentViewHolderSystem.trainingIconImage.setImageResource(icon);
//                Set Title
fragmentViewHolderSystem.title.setText(modelSystemTraining.getItemTitle());
//                Set Desc
fragmentViewHolderSystem.description.setText(modelSystemTraining.getItemDescription());

I had the same problem as you and I did the following to solve it:

**IMAGEVIEW**.setImageResource(getActivity()
             .getResources()
             .getIdentifier("**IMG**", "drawable", getActivity()
             .getPackageName()));

This works, at least in Android API 15

ImageView = imgv;
Resources res = getResources(); // need this to fetch the drawable
Drawable draw = res.getDrawable( R.drawable.image_name_in_drawable );
imgv.setImageDrawable(draw);

You could use setImageResource(), but the documentation specifies that "does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup ... consider using setImageDrawable() or setImageBitmap()." as stated by chetto

The resource drawable names are not stored as strings, so you'll have to resolve the string into the integer constant generated during the build. You can use the Resources class to resolve the string into that integer.

Resources res = getResources();
int resourceId = res.getIdentifier(
   generatedString, "drawable", getPackageName() );
imageView.setImageResource( resourceId );

This resolves your generated string into the integer that the ImageView can use to load the right image.

Alternately, you can use the id to load the Drawable manually and then set the image using that drawable instead of the resource ID.

Drawable drawable = res.getDrawable( resourceId );
imageView.setImageDrawable( drawable );

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);

The 'R' file can not be generated at the run time of the app. You may use some other alternatives such as using if-else or switch-case

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));
