Setting text to a custom dialog class

I am trying to build a custom Dialog that I am setting the text Dynamically. Here is my code that is throwing a NullPointerException. UPDATAED CODE

  listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            HomeItem homeItem = (HomeItem) adapter.getItem(position);
            final Dialog dialog = new Dialog(databaseFightCard.this, android.R.style.Theme_Black_NoTitleBar_Fullscreen);
            WindowManager.LayoutParams lp = (dialog.getWindow().getAttributes());
            lp.dimAmount = 0.5f;
            dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

            Window window = dialog.getWindow();
            window.setGravity(Gravity.CENTER);

            dialog.setContentView(R.layout.custom_dialog);

            LayoutInflater inflater = (LayoutInflater) databaseFightCard.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
           RelativeLayout relative = (RelativeLayout) inflater.inflate(R.layout.custom_dialog, null, false);

            Button play = (Button) findViewById(R.id.bPlay);
            Button done = (Button) findViewById(R.id.bDone);
            TextView rn = (TextView) findViewById(R.id.tvRName);
            TextView ra = (TextView) findViewById(R.id.tvRAge);
            TextView rr = (TextView) findViewById(R.id.tvRRecord);
            TextView rh = (TextView) findViewById(R.id.tvRHeight);
            TextView rw = (TextView) findViewById(R.id.tvRWeight);
            TextView rc = (TextView) findViewById(R.id.tvRCity);
            TextView re = (TextView) findViewById(R.id.tvRExp);
            TextView bn = (TextView) findViewById(R.id.tvBName);
            TextView ba = (TextView) findViewById(R.id.tvBAge);
            TextView br = (TextView) findViewById(R.id.tvBRecord);
            TextView bh = (TextView) findViewById(R.id.tvBHeight);
            TextView bw = (TextView) findViewById(R.id.tvBWeight);
            TextView bc = (TextView) findViewById(R.id.tvBCity);
            TextView be = (TextView) findViewById(R.id.tvBExp);


            rn.setText(homeItem.getHomeItemRedName()+"");
            ra.setText(homeItem.getHomeItemRedAge()+"");
            rr.setText(homeItem.getHomeItemRedRecord()+"");
            rh.setText(homeItem.getHomeItemRedHeight()+"");
            rw.setText(homeItem.getHomeItemRedWeight()+"");
            rc.setText(homeItem.getHomeItemRedCity()+"");
            re.setText(homeItem.getHomeItemRedExp()+"");
            bn.setText(homeItem.getHomeItemBlueName()+"");
            ba.setText(homeItem.getHomeItemBlueAge()+"");
            br.setText(homeItem.getHomeItemBlueRecord()+"");
            bh.setText(homeItem.getHomeItemBlueHeight()+"");
            bw.setText(homeItem.getHomeItemBlueWeight()+"");
            bc.setText(homeItem.getHomeItemBlueCity()+"");
            be.setText(homeItem.getHomeItemBlueExp()+"");
            dialog.setContentView(relative);

            play.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    //add the play intent here
                    dialog.dismiss();
                }
            });

            done.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    dialog.dismiss();
                }
            });
                dialog.show();

        }
    });

I am getting NullPointerException on

rn.setText(homeItem.getHomeItemRedName()+"");

Please explain how I can set the text to my Dialog.

Try showing your dialog first, as in, put dialog.show before you try to find the textViews. Either that, or inflate your view first and pass the view to the dialog. What you're doing now is trying to find the view before it's inflated.

Edit: To use the inflator, try this,

   LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

   RelativeLayout view = (RelativeLayout)inflater.inflate(R.layout.custom_dialog, null, false);

   TextView rn = (TextView) view.findViewById(R.id.tvRName);

   dialog.setContentView(view);

Edit 2:

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        HomeItem homeItem = (HomeItem) adapter.getItem(position);
        final Dialog dialog = new Dialog(databaseFightCard.this, android.R.style.Theme_Black_NoTitleBar_Fullscreen);
        WindowManager.LayoutParams lp = (dialog.getWindow().getAttributes());
        lp.dimAmount = 0.5f;
        dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

        Window window = dialog.getWindow();
        window.setGravity(Gravity.CENTER);

        LayoutInflater inflater = (LayoutInflater) databaseFightCard.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
       RelativeLayout relative = (RelativeLayout) inflater.inflate(R.layout.custom_dialog, null, false);

        dialog.setContentView(relative);

        Button play = (Button) relative.findViewById(R.id.bPlay);
        Button done = (Button) relative.findViewById(R.id.bDone);
        TextView rn = (TextView) relative.findViewById(R.id.tvRName);
        TextView ra = (TextView) relative.findViewById(R.id.tvRAge);
        TextView rr = (TextView) relative.findViewById(R.id.tvRRecord);
        TextView rh = (TextView) relative.findViewById(R.id.tvRHeight);
        TextView rw = (TextView) relative.findViewById(R.id.tvRWeight);
        TextView rc = (TextView) relative.findViewById(R.id.tvRCity);
        TextView re = (TextView) relative.findViewById(R.id.tvRExp);
        TextView bn = (TextView) relative.findViewById(R.id.tvBName);
        TextView ba = (TextView) relative.findViewById(R.id.tvBAge);
        TextView br = (TextView) relative.findViewById(R.id.tvBRecord);
        TextView bh = (TextView) relative.findViewById(R.id.tvBHeight);
        TextView bw = (TextView) relative.findViewById(R.id.tvBWeight);
        TextView bc = (TextView) relative.findViewById(R.id.tvBCity);
        TextView be = (TextView) relative.findViewById(R.id.tvBExp);


        rn.setText(homeItem.getHomeItemRedName()+"");
        ra.setText(homeItem.getHomeItemRedAge()+"");
        rr.setText(homeItem.getHomeItemRedRecord()+"");
        rh.setText(homeItem.getHomeItemRedHeight()+"");
        rw.setText(homeItem.getHomeItemRedWeight()+"");
        rc.setText(homeItem.getHomeItemRedCity()+"");
        re.setText(homeItem.getHomeItemRedExp()+"");
        bn.setText(homeItem.getHomeItemBlueName()+"");
        ba.setText(homeItem.getHomeItemBlueAge()+"");
        br.setText(homeItem.getHomeItemBlueRecord()+"");
        bh.setText(homeItem.getHomeItemBlueHeight()+"");
        bw.setText(homeItem.getHomeItemBlueWeight()+"");
        bc.setText(homeItem.getHomeItemBlueCity()+"");
        be.setText(homeItem.getHomeItemBlueExp()+"");
        dialog.setContentView(relative);

        play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //add the play intent here
                dialog.dismiss();
            }
        });

        done.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dialog.dismiss();
            }
        });
            dialog.show();

    }
});
