I'm not able to show an image which is saved in res/drawable folder. I use ImageGetter to do this. The code is below:

ImageGetter imageGetter3 = new ImageGetter() {                
    public Drawable getDrawable(String source) { 
        int id=0; 
        if (source.equals("smiley")) { 
            id = R.drawable.smiley; 
        } 
        Drawable d = getResources().getDrawable(id); 
        d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight()); 
        return d; 
    } 
};

directions += "Je bent bij lokaal " + vertrek.getNaam() + "\n" 
           + "Sta met je rug voor de deur\n" 
           + Html.fromHtml("<img src=\"smiley\">", imageGetter3, null) + " Draai naar links\n";

What I see on the screen when running is a little square with "obj" text on it. So what is wrong? The image cannot be read or something else? How to show images?

Honestly I have Googled a lot and tried other methods of ImageGetter as well, but none of them seems to work, I tried these too, they don't work:

ImageGetter imageGetter2 = new ImageGetter() { 
 public Drawable getDrawable(String source) { 
      Drawable d = null; 
      d = Drawable.createFromPath(source); 
      d.setBounds(0,0, d.getIntrinsicWidth(), d.getIntrinsicHeight()); 
      return d; 
 } 
};

ImageGetter imageGetter = new ImageGetter() {                
 public Drawable getDrawable(String source) { 
     Drawable drawFromPath; 
     int path = Route.this.getResources().getIdentifier(source, "drawable","com.prj56.tracingapp"); 
     drawFromPath = (Drawable) Route.this.getResources().getDrawable(path); 
     drawFromPath.setBounds(0, 0, drawFromPath.getIntrinsicWidth(), drawFromPath.getIntrinsicHeight()); 
     return drawFromPath; 
 } 
};

========================================================= if (....) { ImageView iv1 = new ImageView(this); iv1.setImageResource(R.drawable.smiley);

    directions += "Je bent bij lokaal " + vertrek.getNaam() + "\n" 
       + "Sta met je rug voor de deur\n";
       HERE COMES THE IMAGE! BUT HOW TO DO THIS? It's within directions textview...
    directions += " Draai naar links\n";

}

You can get the image with the help of pImg.Based on the adapter position get the string that is the image name.The image should be present in the drawable folder.

ImageView prodImg=(ImageView)view.findViewById(R.id.img_proj_name);
    String pImg=prod.get(position);
    int resID = view.getResources().getIdentifier("@drawable/"+pImg , "drawable", parentView.getContext().getPackageName());
    prodImg.setImageResource(resID);

Easiest way - Can be consider the below code

We can take advantage of Imageview setImageResource , refer below code for the same. put image in the drawable like the below order

image_1.png, image_2.png, etc.

int resId = getResources().getIdentifier("image_" + imagePosition, "drawable", getPackageName());
             imageview.setImageResource(resId);

  Drawable drawable = getResources().getDrawable(R.mydrawableID);

Now you can use it as Image, Like:-

ImageView myImage = findViewById(R.id.yourImageView);

Now fire this - 

myImage.setImageResource(drawable);

You should use ContextCompat for backward compatibility features on Android.

//Using ButterKnife
@BindView(R.id.DogImg)
    ImageView myImage;
//Or 
  ImageView myImage = findViewById(R.id.MyImage);
...
Drawable MyImageDrw = ContextCompat.getDrawable(context,R.drawable.myImageOnResources);
myImage.setImageDrawable(MyImageDrw);
