时间选择器

1.以popupWindow的形式显示出来所以会引用一个xml文件

直接定义一个方法

    Calendar calendar = Calendar.getInstance();
    public int mDay;
    public int mMonth;
    public int mYear;
    
    public void setDate(final TextView pEnd) {
        //点击"日期"按钮布局 设置日期
        //通过自定义控件AlertDialog实现
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        View view = (LinearLayout) getLayoutInflater().inflate(R.layout.date_dialog, null);
        final DatePicker datePicker = (DatePicker) view.findViewById(R.id.date_picker);
        //设置日期简略显示 否则详细显示 包括:星期\周
        datePicker.setCalendarViewShown(false);
        //初始化当前日期
        calendar.setTimeInMillis(System.currentTimeMillis());
        datePicker.init(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
                calendar.get(Calendar.DAY_OF_MONTH), null);
        //设置date布局
        builder.setView(view);
        builder.setTitle("设置日期信息");
        builder.setPositiveButton("确  定", new DialogInterface.OnClickListener() {


            @Override
            public void onClick(DialogInterface dialog, int which) {
                //日期格式
                StringBuffer sb = new StringBuffer();
                sb.append(String.format("%d-%02d-%02d",
                        datePicker.getYear(),
                        datePicker.getMonth() + 1,
                        datePicker.getDayOfMonth()));
                pEnd.setText(sb);
                //赋值后面闹钟使用
                mYear = datePicker.getYear();
                mMonth = datePicker.getMonth();
                mDay = datePicker.getDayOfMonth();
                dialog.cancel();
            }
        });
        builder.setNegativeButton("取  消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.cancel();
            }
        });
        builder.create().show();

    }

引用的是date_dialog的xml里写中:
