Android - How to show images from resources drawable?

Question

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";

}

Update 12 Dec 2016:

getResources().getDrawable() was deprecated in api 22 so you should now be using ContextCompat.getDrawable e.g.

Drawable d = ContextCompat.getDrawable(context, R.drawable.smiley);

---

In your activity you can call this to get your Drawable resource as a Drawable object

Drawable d = getResources().getDrawable(R.drawable.smiley);

If you want to show your drawable in an ImageView you can do this:

ImageView i = new ImageView(this);
i.setImageResource(R.drawable.smiley);

or in your xml file

<ImageView   
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:src="@drawable/smiley"/>
