回答1:

You can use this

public int[] getIntIds(Integer[] images){
    int[] temp = new int[images.length];
    String name;
    for(int i=0; i<= images.length; i++){
        name = getResources().getResourceEntryName(images[i]);
        temp[i] = getResources().getIdentifier(name , "drawable", getPackageName());
    }
    return temp;
}

You can use this

String mDrawableName = "myimg";
int resID = getResources().getIdentifier(mDrawableName , "drawable", getPackageName());

or

String imageName = "picture";
int resID = getResources().getIdentifier(imageName, "drawable", "package.name");
ImageView image;
image.setImageResource(resID);
