當我按下右箭頭日期在textView增加現在我需要在datePicker的對話框上設置日期。當我按刷新然後它設置爲當前日期，但不是當我按左箭頭和右箭頭。我該怎麼做才能做到這一點？DatePicker的當前日期將在日期選取器的對話框中突出顯示
iv_refresh.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
count = 0;
getDate(count);
setDateTimeField();
}
});
rightarrow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getDate(1);
}
});
leftarraow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getDate(-1);
}
});
tv_date.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
icount=0;
DOBPickerDialog.show();
}
});

//milliseconds
