U need to show the selected list item (Image + text), in the next activity, right ?, If so, Use Bundle to put those datatype that you need to pass to the next activity and retrieve it in the next activity. — Nandagopal T, Nov 28 '12 at 09:12
where exactly you are passing An image?! remember you can not pass image file directly , you need to decode it first — Mahdi Giveie, Nov 28 '12 at 09:13

I agree with @NandagopalT You can pass an image object and string to the bundle with key-value pair. Do it in onItemClick method, not in onCLick. — 0xC0DED00D, Nov 28 '12 at 09:29
You can use putExtra, as other people also mentioned. And also you can use static reference of image and text and use them anywhere in the app (in all the activities) — Tahreem, Nov 28 '12 at 09:20

If you need to pass a image between two activities means, first you must covert the image to bitmap, then use this code to pass the bitmap,

 Intent intent = new Intent(Current.this, Next.class);
 intent.putExtra("bmp", bitmap); // for image
 intent.putExtra("text", text); //for text 
 startActivity(intent);

in activity two use this,

 Bitmap bitmap = getIntent().getParcelableExtra("bmp");

You cannot pass big image via intent's extra. But in your code, it seems all images are drawable resources. So you can just pass the resource id which is just "int" number, then reload image from resource in the next activity.

Effectively you can transform your image into a bitmap, but i think it's not optimized and can take so much time. As much as possible, you should put the image's reference in your Extra (like its ressource ID).

Put the buffer of the bitmap into the putExtra, as below:

Bitmap.getPixels(int[] mybuffer,...)

Intent.putExtra("MyBuffer",mybuffer)

To get it from other activity, just do:

int[] mynewbuffer = Intent.getIntArrayExtra("MyBuffer")

Bitmap myBitmap = Bitmap.createBitmap(mybuffer,...)
