Android-如何显示可绘制资源中的图像？

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\";

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; 
 } 
};  

    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\";

}
