我正在使用datepicker对话框来显示日期，但我想在对话框中更改分隔符

Question

我正在使用datepicker对话框显示dateformat对话框，我想更改datepicker的divders颜色以及如何自定义datepickerdailog为三个蓝色分隔符是单行。我可以自定义datepicker对话框，如第二张图片

我从datepickersdialog获得了这个对话框。  

//我正在使用代码来显示datepicker对话框：

公共类MainActivity扩展了Activity {

private EditText txtView;
private String initialDate;
private String initialMonth;
private String initialYear;
private DatePickerDialog dialog = null;
Context context;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Button btn = (Button) findViewById(R.id.button1);
    txtView = (EditText) findViewById(R.id.textView1);
    context = getApplicationContext();
    btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Calendar dtTxt = null;

            String preExistingDate = (String) txtView.getText().toString();

            if (preExistingDate != null && !preExistingDate.equals("")) {
                StringTokenizer st = new StringTokenizer(preExistingDate,
                        "/");

                System.out.println("datepicker dialog if condition");
                initialMonth = st.nextToken();
                initialDate = st.nextToken();
                initialYear = st.nextToken();
                if (dialog == null)
                    dialog = new DatePickerDialog(v.getContext(),
                            new PickDate(), Integer.parseInt(initialYear),
                            Integer.parseInt(initialDate), Integer
                                    .parseInt(initialMonth) - 1);


                dialog.updateDate(Integer.parseInt(initialYear),
                        Integer.parseInt(initialDate),
                        Integer.parseInt(initialMonth) - 1);


            } else {


                dtTxt = Calendar.getInstance();
                if (dialog == null)
                    System.out.println("datepicker dialog if condition else part");
                    dialog = new DatePickerDialog(v.getContext(),
                            new PickDate(), dtTxt.getTime().getYear(),
                            dtTxt.getTime().getDay(), dtTxt.getTime()
                                    .getMonth());
                dialog.updateDate(dtTxt.getTime().getYear(), dtTxt
                        .getTime().getDay(), dtTxt.getTime().getMonth());

                dialog.setTitle("");
            }

            dialog.show();
        }

    });
}

private class PickDate implements DatePickerDialog.OnDateSetListener {

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {
        view.updateDate(year, monthOfYear, dayOfMonth);
        txtView.setText(monthOfYear + "/" + dayOfMonth + "/" + year);
        dialog.hide();
    }

}

//我想像这样更改对话框分隔符： 应该改变蓝色线，我想要完整的线也如下图所示：

我无法找到内置DatePicker的主题，因此我使用了这个库并构建了自己的库。
