where is wrong

Java Code

Drawable drawable = mContext.getResources().getDrawable(mContext.getResources().getIdentifier(mData.get(position).getImage(), "drawable", mContext.getPackageName()));             
    holder.image.setImageDrawable(drawable);

Layout

<ImageView
                android:id="@+id/fish_image"
                android:layout_width="match_parent"
                android:scaleType="fitXY"
                android:minWidth="100dp"
                android:minHeight="100dp"
                android:background="#ffffff"
                android:layout_height="wrap_content"
                />

I have 700 images in Drawable and I have a list of image name and I need to load it into image view programmatically is there any other solution

Update it worked
i moved image to Assets folder and load it from there

try {
            // get input stream
            InputStream ims = mContext.getAssets().open(mData.get(position).getImagename()+".webp");
            // load image as Drawable
            Drawable d = Drawable.createFromStream(ims, null);
            // set image to ImageView
            holder.image.setImageDrawable(d);
            ims .close();
        }
        catch(IOException ex)
        {
            Log.e("image_io",ex.getMessage()+"");
           // return;
        }

What is `getIdentifier()` returning there? What is `getImage()` returning? Do you actually have a drawable resource by that name, applicable to the current configuration? What happens if you temporarily use the `R.drawable` value? For that matter, why aren't you just using the `R.drawable` values in your data model to begin with? — Mike M., Aug 12 '18 at 07:37

You should use the name of the drawable as string and not getImageuri():

Drawable drawable = mContext.getResources().getDrawable(mContext.getResources().getIdentifier("drawable_name", "drawable", mContext.getPackageName()));

image uri is string – Midhilaj Aug 12 '18 at 07:29
Why do you need a uri for images in drawable folder? – Aug 12 '18 at 07:38
Is getImageuri().toString() just the name of the drawable, or not? Check it. – Aug 12 '18 at 07:39

getImageuri() return image name like "Malawi_shell_dweller" – Midhilaj Aug 12 '18 at 07:41
In this code where i need to add image name ?
Drawable drawable = mContext.getResources().getDrawable(mContext.getResources().getIdentifier("drawable_name", "drawable", mContext.getPackageName()));

@Midhilaj 700 images? so add them to "assets" folder and use `android.content.res.AssetManager` for getting them in your app – pskink Aug 12 '18 at 07:43

@Midhilaj Try with just one single drawable's name. If this does not work then the problem is elsewhere – Aug 12 '18 at 07:50
@Midhilaj what is `"not working"`? is `InputStream ims` null or what? – pskink Aug 12 '18 at 07:52
@Midhilaj and of course cache those `Drawable`s in some `HashMap` so that you call `Drawable.createFromStream` only once for given name – pskink Aug 12 '18 at 08:28

Uri uri_for_drawable = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE +
                "://" + getResources().getResourcePackageName(R.drawable.your_image_name)
                + '/' + getResources().getResourceTypeName(R.drawable.your_image_name) + '/' + getResources().getResourceEntryName(R.drawable.your_image_name) );

Use the above code to get the image uri from drawable folder.
