Android custom dialog method

Question

Can someone tell me why cannot i call setOnClickListener method on my buton in custom dialog method? Is there a possible way to handle clicks in this kind of dialog? Here's the code:

private Dialog wifiDialog() { final Dialog dialog = new Dialog(activity); dialog.setContentView(R.layout.wifi_dialog); dialog.setTitle("Upload"); Button no = (Button) findViewById(R.id.button_wifi_No); Button yes = (Button) findViewById(R.id.button_wifi_Yes); no.setOnClickListener(new OnClickListener() { // runtimeException @Override public void onClick(View v) { wifiDialog().dismiss(); } }); return dialog; }

Thanks in advance

Try this.

private Dialog wifiDialog(Context context) { final Dialog dialog = new Dialog(context); LayoutInflater layoutInflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View view = layoutInflater.inflate(R.layout.wifi_dialog,null); dialog.setContentView(view); dialog.setTitle("Upload"); Button no = (Button) view.findViewById(R.id.button_wifi_No); Button yes = (Button) view.findViewById(R.id.button_wifi_Yes); no.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { dialog.dismiss(); } }); return dialog; }

And use :

wifiDialog(this); // In activity context;

I explain you why you getting error. You cycle your logic. In onClick method you try to create another dialog and set same click listener to the same button. SO if you want to dismiss your dialog use the instanse of dialog, instead of creation new.

Please don't just post code with no explanation of what you changed and why, or the OP (and future visitors) learn nothing.
