I'm trying to retrieve some information from my onActivityResult method, in my case is a picture the user has selected in a subactivity, i believe that is working fine, what i am having problems with is when i try to assign that picture (in form of a byte array) to a variable i have in my main activity. I'm trying to use that variable in a onClick method, but for some reason when i try to use that variable it's value is always null. what could be happening? here is the code:

poptions.setOnItemClickListener(new OnItemClickListener(){

        @Override
        public void onItemClick(AdapterView<?> arg0, View view, int pos, long id) {
            final Intent i;
            switch(pos){
            // Adjunta imagen
            case 0:
                i = new Intent(Intent.ACTION_GET_CONTENT);
                i.setType("image/jpeg");
                startActivityForResult(i,1);
                //Toast.makeText(view.getContext(), "MIERDA!!", 30).show();
                break; // more cases below, not relevant to my question....
                }
        }

    });

my onActivityResult method:

EDIT: The solution was to change

if(resultCode==1)

to:

if(resultCode==RESULT_OK)

turns out, RESULT_OK actually equals -1.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent pic){
    super.onActivityResult(requestCode, resultCode, pic);
    if(resultCode==1){

        Uri selectedpic = pic.getData();

        try {
            Bitmap bitmappic = MediaStore.Images.Media.getBitmap(
                    this.getContentResolver(), 
                    selectedpic);

            ByteArrayOutputStream picstream = new ByteArrayOutputStream();

            bitmappic.compress(Bitmap.CompressFormat.JPEG, 100, picstream);
            setPicture(picstream.toByteArray());

        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}

my onClickListener method where i'm trying to use the picture that was set by my setPicture method above.

        btnSend.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {
                Bundle usrpostData = new Bundle();
                if(txtMsg.getText().toString().equals("")){
                    Toast.makeText(v.getContext(), "MSG", 10).show();
                }else{
                    String msg = txtMsg.getText().toString();
                    usrpostData.putString("message", msg);
                    if(getPicture()==null){
                        Toast.makeText(v.getContext(),"NULL",30).show();
                    }else{
                        try {
                            // do something with the picture...

                        } catch (FileNotFoundException e) {
                            e.printStackTrace();
                        } catch (MalformedURLException e) {
                            e.printStackTrace();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }

        });

As you can see i put a little test, and the getPicture method always return null, i tried .equals instead of == and it makes my app crash. any help is appreciated

有帮助吗?
