应用程序中所有对话框的自定义主题

Question

Is there any similar theme generator as HoloColors or Action Bar Style Generator which would help us change theme of Dialogs and AlertDialogs in our apps?

My app uses Holo theme and I managed to change style of views such as EditTexts and Buttons but they remain unchanged when they appear in a Dialog. I would also like to change color of the blue line under a title.

I've found a few question and answers related to this topic but they practically say it's not even possible. I cannot believe it isn't.

At least for the AlertDialog it is possible. here i posted my solution of a function which is called at some point (for example button click) in your code and creates an alert dialog own layout over your screen.. the layout is a normal layout.xml which you can define the way you want. works perfect for me!

private void showAddUserGeneratedStationDialog() {

        AlertDialog.Builder alertDialog = new AlertDialog.Builder(
                AmplifyActivity.this);

        LayoutInflater inflater = getLayoutInflater();

            //inflate your layout.xml
        alertDialog
                .setView(inflater.inflate(R.layout.dialog_add_station, null));

            //show dialog over activity screen
        final AlertDialog ad = alertDialog.show();

            //put actions to your ui-elements
        Button cancelBtn = (Button) ad
                .findViewById(R.id.list_user_generated_cancelBU);
        cancelBtn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                ad.cancel();
            }
        });

        Button doneBtn = (Button) ad
                .findViewById(R.id.list_user_generated_doneBU);
        doneBtn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                            //get sth from your layout f.e. some textInput
                String stationUrl = ((TextView) ad
                        .findViewById(R.id.list_user_generated_stationURLInput))
                        .getText().toString();

                    // did some other things

                ad.dismiss();

            }
        });

    }

and my layout.xml
