Android studio 最精简代码的日期选择器 只有 年 月

如果没用到可以删除对应代码

@RequiresApi(api = _)

(资料图)

public static void openDateStartDialog(final TextView startdate, Context context) {

final Calendar calendar = ();

int yy = ();

int mm = ();

int dd = (_OF_MONTH);

new ContextThemeWrapper(context,_Holo_Light_Dialog_NoActionBar);

(("yyyy-MM-dd", ().toString().trim()));

DatePickerDialog dlg = new DatePickerDialog(new ContextThemeWrapper(context,

_Holo_Light_Dialog_NoActionBar), null, yy, mm, dd) {

@Override

protected void onCreate(Bundle savedInstanceState) {

(savedInstanceState);

LinearLayout mSpinners = (LinearLayout) findViewById(getContext().getResources().getIdentifier("android:id/pickers", null, null));

if (mSpinners != null) {

NumberPicker mMonthSpinner = (NumberPicker) findViewById(getContext().getResources().getIdentifier("android:id/month", null, null));

NumberPicker mYearSpinner = (NumberPicker) findViewById(getContext().getResources().getIdentifier("android:id/year", null, null));

();

if (mYearSpinner != null) {

(mYearSpinner);

}

if (mMonthSpinner != null) {

(mMonthSpinner);

}

}

View dayPickerView = findViewById(getContext().getResources().getIdentifier("android:id/day", null, null));

if(dayPickerView != null){

();

}

}

@Override

public void onDateChanged(DatePicker view, int year, int month, int day) {

(view, year, month, day);

setTitle("请选择对应的日期");

}

};

("请选择对应的日期");

(new () {

@Override

public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {

(year + "-" + (month + 1 < 10 ? "0" + (month + 1) : (month + 1)) );

}

});

();

}

下面附上对应的效果图

常用的  年月日 这里也贴出来了，当然改一下上面的也行，但是这个感觉根据对应版本号会好看一点，也是塞入一个TextView和this就可以了，你可以放在点击事件里面调用

使用方法： 

openDateStartDialog(tv_time, this);

public static void openDateStartDialog(final TextView startdate,  Context context) {

final Calendar localCalendar = ();

(("yyyy-MM-dd", ().toString().trim()));

new MonPickerDialog(context, new () {

@Override

public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {

(, year);

(, month);

(_OF_MONTH, dayOfMonth);

String day = dayOfMonth >= 10 ? dayOfMonth + "" : "0" + dayOfMonth;

(year + "-" + (month + 1 < 10 ? "0" + (month + 1) : (month + 1)) + "-" + day);

}

},

(), (), (_OF_MONTH)).show();

}

public static class MonPickerDialog extends DatePickerDialog {

public MonPickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {

super(context, callBack, year, monthOfYear, dayOfMonth);

}

@Override

public void onDateChanged(DatePicker view, int year, int month, int day) {

(view, year, month, day);

}

}
