Answer 1

You can Create Common Function for getting image drawable like this:

public static Drawable getDrawable(Context mContext, String name) {
        int resourceId = mContext.getResources().getIdentifier(name, "drawable", mContext.getPackageName());
        return mContext.getResources().getDrawable(resourceId);
    }

Answer 2

if you have the image in the drawable folder you are going about this the wrong way.

try something like this

Resources res = getResources();
String mDrawableName = "logo_default";
int resID = res.getIdentifier(mDrawableName , "drawable", getPackageName());
Drawable drawable = res.getDrawable(resID );
icon.setImageDrawable(drawable );

Answer 3

No need to use getDrawable() you directly use the resource id like

String mDrawableName = "myimageName"; int resID = res.getIdentifier(mDrawableName , "drawable", getPackageName()); imgView.setImageResource(resID);

Answer 4

ImageView img = (ImageView) findViewById(R.id.{ImageView id});
img.setImageResource(getResources().getIdentifier("ImageName","drawable",getPackageName()));
