onClickListener on imageview to start new intent

Question

So Im trying to use an onClickListener to pass an image from one activity to a new activity but I cannot figure out how to do it. How it works is the app starts with a listv

Answer 1

Use your image as ByteArray. This worked for me without any problem. In your click listener of the sender activity do the following,

Intent senderint = new Intent(context, receiveractivity.class);
Bitmap bitmap = drawableToBitmap(view.getBackground());
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] b = baos.toByteArray();
senderint.putExtra("myimage", b);
startActivity(senderint);

And in your receiver activity do the following.

private void getImage(){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = null;
v = inflater.inflate(R.layout.receiverlayout, null);

ViewGroup vg = (ViewGroup) findViewById(R.id.yourmainlayout);
Bundle bundle = getIntent().getExtras();
byte[] ba = bundle.getByteArray("myimage");
Bitmap bm = BitmapFactory.decodeByteArray(ba, 0, ba.length());
Drawable dr = new BitmapDrawable(getResources, bm);
vg.setBackground(dr);
vg.addView(v, 0, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
}

call getImage() in your oncreate method of your receiver activity. The context is your application context. Good luck:)

You're putting in the extra with the key imageResourceId but you're trying to pull it out with the key imageFullScreen. Try using the same key in both places.
