These are real items, at my local grocery store, where I took

Hi Bill,
Here's what the "custom" shopping list looks like on the phone:
http://www.bild.me/bild.php?file=5881250androidstudio73.jpg

The original design is pretty good because everything is just an
item in a list, which can be of any length.

Hence, the only files that changed to create that shopping list were
C:\tmp\android\app08\app\src\main\res\values\strin gs.xml
C:\tmp\android\app08\app\src\main\java\com\kiss\ap p08\DetailActivity.java

Where these are the files:
================================================== ==========================
I added the items to the "strings.xml" file:
C:\tmp\android\app08\app\src\main\res\values\strin gs.xml

resources
string name="app_name"app08/string

string-array name="items"
itemchocolate/item

And I added the switches to the DetailActivity.java file:

public class DetailActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);

Intent in = getIntent();
int index = in.getIntExtra("com.kiss.app08.ITEM_INDEX", -1);

if (index -1) {
int pic = getImg(index);
ImageView img = (ImageView) findViewById(R.id.imageView);
scaleImg(img, pic);
}

}

private int getImg(int index) {
switch (index) {
case 0: return R.drawable.chocolate;
case 1: return R.drawable.egg;
case 2: return R.drawable.milk;
case 3: return R.drawable.oj;
case 4: return R.drawable.pasta;
case 5: return R.drawable.pj;
case 6: return R.drawable.vino;
case 7: return R.drawable.wrap;
default: return -1;
}
}

private void scaleImg(ImageView img, int pic) {
Display screen = getWindowManager().getDefaultDisplay();
BitmapFactory .Options options = new BitmapFactory.Options();

options.inJustDecodeBounds = true;
BitmapFactory.decodeResource(getResources(), pic, options);

int imgWidth = options.outWidth;
int screenWidth = screen.getWidth();

if (imgWidth screenWidth) {
int ratio = Math.round( (float) imgWidth / (float)screenWidth);
options.inSampleSize = ratio;
}

options.inJustDecodeBounds = false;
Bitmap scaledImg = BitmapFactory.decodeResource(getResources(),
pic, options);
img.setImageBitmap(scaledImg);
}
}

The rest of the files were untouched from what they were in app06.
