Android-PickerView没有月份用英文的控件,在Issues中有人贴出了方法.继承WheelView实现:

public class EnglishMonthWheelView extends WheelView {     public EnglishMonthWheelView(Context context) {         super(context);     }     public EnglishMonthWheelView(Context context, AttributeSet attrs) {         super(context, attrs);     }     @Override     protected String getContentText(Object item) {         if (item == null || TextUtils.isEmpty(item.toString())) {             return "";         } else if (item instanceof IPickerViewData) {             return ((IPickerViewData) item).getPickerViewText();         } else if (item instanceof Integer) {             //如果为整形则最少保留两位数.             int value = (int) item;             String month = null;             switch (value) {                 case 1:                     month = "Jan";                     break;                 case 2:                     month = "Feb";                     break;                 case 3:                     month = "Mar";                     break;                 case 4:                     month = "Apr";                     break;                 case 5:                     month = "May";                     break;                 case 6:                     month = "Jun";                     break;                 case 7:                     month = "Jul";                     break;                 case 8:                     month = "Aug";                     break;                 case 9:                     month = "Sep";                     break;                 case 10:                     month = "Oct";                     break;                 case 11:                     month = "Nov";                     break;                 case 12:                     month = "Dec";                     break;             }             return month;         }         return item.toString();     } } 

使用的如下:

fun ContactFragment.selectBirthDatePV(mTargetView: YSelectTextView) {     activity?.apply {         KeyboardUtils.hideSoftInput(this) //影藏软键盘     }     var btnCancel: Button? = null     var btnConfirm: Button? = null     val selectedDate = Calendar.getInstance();     val startDate = Calendar.getInstance();     val endDate = Calendar.getInstance();     startDate.set(1965, 0, 1);     endDate.set(2004, 11, 31);     selectedDate.set(1990, 0, 1);     val mBirthDateTPV = TimePickerBuilder(activity, object : OnTimeSelectListener {         override fun onTimeSelect(date: Date?, p1: View?) {             date?.apply {                 val mDisplayData = this.dateToEnglishDateStr()// 将Date日期转为英文Date日期                 mTargetView.content = mDisplayData             }         }     })         .setLayoutRes(R.layout.layout_pickerview_item_timer) {             btnCancel = it.findViewById<Button>(R.id.btn_cancel)             btnConfirm = it.findViewById<Button>(R.id.btn_confirm)             it.findViewById<TextView>(R.id.tv_title_desc).text =                 resources.getString(R.string.date_of_birth)         }         .setRangDate(startDate, endDate)         .setDate(selectedDate)         .setTextXOffset(0, 0, 0, 40, 0, -40)         .setLabel("", "", "", "", "", "")//默认设置为年月日时分秒         .isDialog(true)         .setItemVisibleCount(17)         .build()     mBirthDateTPV.show()     btnConfirm?.setOnClickListener {         mBirthDateTPV.returnData()         mBirthDateTPV.dismiss()     }     btnCancel?.setOnClickListener {         mBirthDateTPV.dismiss()     } } 

Dialog模式调整位置

Activity重写了返回键操作,在不同Fragment中会弹出PV,此时返回键被重写了,无法在按返回键的时候隐藏PV,这个时候用Dialog模式可以很好的处理这个问题,但是当前PV里使用Dialog布局就会居中,想要布局再最底部就要改源码,阅读源码发现BasePickerView.createDialog()中创建的Dialog,下面是修改后的createDialog()方法.

public void createDialog() {     if (dialogView != null) {         mDialog = new Dialog(context, R.style.custom_dialog2);         mDialog.setCancelable(mPickerOptions.cancelable);//不能点外面取消,也不能点back取消         mDialog.setContentView(dialogView);         Window dialogWindow = mDialog.getWindow();         if (dialogWindow != null) {             dialogWindow.setWindowAnimations(R.style.picker_view_slide_anim);             dialogWindow.setGravity(Gravity.CENTER);//可以改成Bottom         }         // 手动设置Dialog样式的PickerView在屏幕底部,并且宽度为屏幕宽度,这样可以PickerView可以自动接管返回按键事件         WindowManager.LayoutParams attributes = dialogWindow.getAttributes();         attributes.width = WindowManager.LayoutParams.MATCH_PARENT;         attributes.gravity = Gravity.BOTTOM;         dialogWindow.setAttributes(attributes);         mDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {             @Override             public void onDismiss(DialogInterface dialog) {                 if (onDismissListener != null) {                     onDismissListener.onDismiss(BasePickerView.this);                 }             }         });     } }
