Problems getting Image past AlertDialog

I have some code that get's a pic from the camera gallery. It works fine when you use a button from an activity to get pic and put pic on that activity but I cant get it to my Imageview when I try this with a button on AlertDialog. Any help?

This code by itself is fine

    ((Button)dialogView.findViewById(R.id.button3))
            .setOnClickListener(new OnClickListener() {
                public void onClick(View arg0) {
                    Intent intent = new Intent();
                    intent.setType("image/*");
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    startActivityForResult(Intent.createChooser(intent,"Select Picture"),SELECT_PICTURE);}
                public void onActivityResult(int requestCode, int resultCode, Intent data) {
                    if (resultCode == RESULT_OK) {
                        if (requestCode == SELECT_PICTURE) {
                            Uri selectedImageUri = data.getData();
                            selectedImagePath = getPath(selectedImageUri);
                            System.out.println("Image Path : " + selectedImagePath);
                            im1.setImageURI(selectedImageUri);}}}
                public String getPath(Uri uri) {
                    String[] projection = { MediaStore.Images.Media.DATA };
                    Cursor cursor = managedQuery(uri, projection, null, null, null);
                    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                    cursor.moveToFirst();
                    return cursor.getString(column_index);}});

But when you add this code to AlertDialog it wont function anymore

        lay1.setOnLongClickListener(new OnLongClickListener() {
            public boolean onLongClick(View v) {
                LayoutInflater myLayout = LayoutInflater.from(context);
                final View dialogView = myLayout.inflate(R.layout.alerthelp, null);
                AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);
                alertDialogBuilder.setView(dialogView);
                final AlertDialog alertDialog = alertDialogBuilder.create();


                ((Button) dialogView.findViewById(R.id.button3))
                        .setOnClickListener(new OnClickListener() {
                            public void onClick(View arg0) {
                                Intent intent = new Intent();
                                intent.setType("image/*");
                                intent.setAction(Intent.ACTION_GET_CONTENT);
                                startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);
                            }

                            public void onActivityResult(int requestCode, int resultCode, Intent data) {
                                if (resultCode == RESULT_OK) {
                                    if (requestCode == SELECT_PICTURE) {
                                        Uri selectedImageUri = data.getData();
                                        selectedImagePath = getPath(selectedImageUri);
                                        System.out.println("Image Path : " + selectedImagePath);
                                        im1.setImageURI(selectedImageUri);
                                    }
                                }
                            }

                            public String getPath(Uri uri) {
                                String[] projection = {MediaStore.Images.Media.DATA};
                                Cursor cursor = managedQuery(uri, projection, null, null, null);
                                int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                                cursor.moveToFirst();
                                return cursor.getString(column_index);
                            }
                        });
                alertDialog.show();
                return true;
            }
        });

I have tested the code on another activity from a Button and it works fine but when I open alertDialog to do it, I cant get the pic back to my imageview. I can still get to my Gallery and click on a pic but when I try to save it it wont put the pic in the imageView.

Try moving the method onActivityResult outside the click listener alongside your other activity methods, like so

public class MyActivity extends Activity {

// other methods and fields

private ImageView im1;

// initialize im1 in your onCreate() method

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
                                if (resultCode == RESULT_OK) {
                                    if (requestCode == SELECT_PICTURE) {
                                        Uri selectedImageUri = data.getData();
                                        selectedImagePath = getPath(selectedImageUri);
                                        System.out.println("Image Path : " + selectedImagePath);
                                        im1.setImageURI(selectedImageUri);
                                    }
                                }
     }
}
