        progressDialog = new ProgressDialog(DialogDemo.this);

        //设置提示信息
        progressDialog.setTitle("提示");
        progressDialog.setIcon(R.mipmap.touxiang0);

        progressDialog.setMessage("正在处理中");

        //是否用过返回键取消
        progressDialog.setCancelable(true);
        //碰触弹框之外的地方取消
        progressDialog.setCanceledOnTouchOutside(true);


        //显示
        progressDialog.show();
    }

DatePickerDialog

 //日期
    private  void datePickerDialog(){
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
            DatePickerDialog datePickerDialog = new DatePickerDialog(DialogDemo.this);
            datePickerDialog.setOnDateSetListener(new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                    Toast.makeText(DialogDemo.this,year+"年"+(month+1)+"月"+dayOfMonth+"日",Toast.LENGTH_SHORT).show();
                }
            });
            datePickerDialog.show();
        }else {
            Toast.makeText(DialogDemo.this,"版本过低",Toast.LENGTH_SHORT).show();

        }
    }

TimePickerDialog

    //时间
    private  void timePickerDialog(){
        //获得日历的实列
        Calendar calendar = Calendar.getInstance();

        //设置当前时间
        calendar.setTimeInMillis(System.currentTimeMillis());

        //获取时分

        int hour  = calendar.get(Calendar.HOUR_OF_DAY);
        int minute = calendar.get(Calendar.MINUTE);


        //第三、四个参数初始时分 第五个参数是否为24小时显示
        TimePickerDialog time = new TimePickerDialog(DialogDemo.this, new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                Toast.makeText(DialogDemo.this,"Hour"+hourOfDay+"minute"+minute,Toast.LENGTH_SHORT).show();

            }
        },hour,minute,true);

        time.show();

    }
