Android-PickerView 定制用法记录

地址

英文日期

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();
    }
}

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);
                }
            }
        });
    }
}
