How to make an event inside the onClick method in android

My requirement is on the click of a image i should give an alert by alertbuilder. It is happening perfectly fine.In the alertbuilder i am referring one layout.Then i am referring the ids of widgets.Then within this scope of onclick method iam making actions for these widgets.

holder.source.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                Toast.makeText(getApplicationContext(), "Source",Toast.LENGTH_LONG).show();
                dialog = new Dialog(RecordingActivity2.this);
                dialog.setTitle("Source File");
                dialog.setContentView(R.layout.activity_read);
                ImageButton im = (ImageButton)findViewById(R.id.close);
                im.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                    **If i am making actions here application is closing unexpectedly.**

                    }
                });
                dialog.show();
                }
            });

Here is my logcat output

Replace 

ImageButton im = (ImageButton)findViewById(R.id.close);

To

ImageButton im = (ImageButton)dialog.findViewById(R.id.close);
