先看下佈局    對應的一個輸入框點選觸發

<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>
 

下面主頁面，開始擼程式碼

public class PersonalActivity extends AppCompatActivity {
EditText personal_info_et_birthday;
    private int mYear, mMonth, mDay;
    private  String mBirthDay;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_personal);

personal_info_et_birthday = findViewById(R.id.personal_info_et_birthday);
personal_info_et_birthday.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        ShowBirthDialog();

    }
});

    }

    private void ShowBirthDialog() {
        Calendar c = Calendar.getInstance();
        mYear = c.get(Calendar.YEAR);
        mMonth = c.get(Calendar.MONTH);
        mDay = c.get(Calendar.DAY_OF_MONTH);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            new DatePickerDialog(PersonalActivity.this, R.style.DatePickThemeDialog, mDateSetListener, mYear, mMonth, mDay)
                    .show();
        }else new DatePickerDialog(PersonalActivity.this,mDateSetListener, mYear, mMonth, mDay)
                .show();


    }

    private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                              int dayOfMonth) {
            if (view.isShown()) {
                mYear = year;
                String mm;
                String dd;
                if (monthOfYear < 9) {
                    mMonth = monthOfYear + 1;
                    mm = "0" + mMonth;
                } else {
                    mMonth = monthOfYear + 1;
                    mm = String.valueOf(mMonth);
                }
                if (dayOfMonth < 10) {
                    mDay = dayOfMonth;
                    dd = "0" + mDay;
                } else {
                    mDay = dayOfMonth;
                    dd = String.valueOf(mDay);
                }

                mMonth = monthOfYear;

                mBirthDay = mYear + "-" + mm + "-" + dd;
                Log.e("birthday",mBirthDay.toString());
                personal_info_et_birthday.setText(mBirthDay);
              /*  submitAccountInfo();*/
            }
        }

    };

}
 

下面就是對應rec檔案下面建立一個values-v21資料夾在裡面建立一個style 這個裡面就是顏色主題 如圖：

style裡面的程式碼

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="DatePickThemeDialog" parent="android:Theme.Material.Light.Dialog">
        <item name="android:colorAccent">@color/theme_color_day</item>
        <item name="android:colorPrimary">@color/theme_color_day</item>
        <item name="android:colorPrimaryDark">@color/theme_color_day</item>

    </style>
</resources>
