实现去哪儿来回机票选择的view

实现去哪儿来回机票选择的view 实现去哪儿来回机票选择的view 最近有个控件是实现和去哪儿和阿里旅行的app的选择日历效果，反编译没有效果的情况下我自己实现了个，大致的原理是: 上面是产品需要实现的效果，我看了下不就是一个ListView+gridView就能实现么，有了，自定义的CalendarView实现对日期的计算，然后可以按iOS显示的风格显示日历 public class MyCalendar extends LinearLayout { private static Context context; private Date theInDay; private String inday = "", outday = ""; private List gvList;//存放天 private CalGridViewAdapter calAdapter; private OnDaySelectListener callBack;//回调函数 public MyCalendar(Context context) { super(context); this.context = context; } public MyCalendar(Context context, AttributeSet attrs) { super(context, attrs); this.context = context; } public void setInDay(String inday) { this.inday = inday; } public void setOutDay(String outday) { this.outday = outday; } public void setTheDay(Date dateIn) { this.theInDay = dateIn; init(); } /** * 初始化日期以及view等控件 */ private void init() { gvList = new ArrayList();//存放天 Calendar cal = Calendar.getInstance();//获取日历实例 cal.setTime(theInDay);//cal设置为当天的 cal.set(Calendar.DATE, 1);//cal设置当前day为当前月第一天 int tempSum = countNeedHowMuchEmpety(cal);//获取当前月第一天为星期几 int dayNumInMonth = getDayNumInMonth(cal);//获取当前月有多少天 setGvListData(tempSum, dayNumInMonth, cal.get(Calendar.YEAR) + "-" + getMonth((cal.get(Calendar.MONTH) + 1))); View view = LayoutInflater.from(context).inflate(R.layout.comm_calendar, this, true);// 获取布局，开始初始化 TextView tv_year = (TextView) view.findViewById(R.id.tv_year); if (cal.get(Calendar.YEAR) > new Date().getYear()) { tv_year.setVisibility(View.VISIBLE); tv_year.setText(cal.get(Calendar.YEAR) + "年"); } TextView tv_month = (TextView) view.findViewById(R.id.tv_month); tv_month.setText(String.valueOf(theInDay.getMonth() + 1) + "月"); MyGridView gv = (MyGridView) view.findViewById(R.id.gv_calendar); calAdapter = new CalGridViewAdapter(context,gvList, inday, outday); gv.setAdapter(calAdapter); gv.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView adapterView, View arg1, int position, long arg3) { String choiceDay = (String) adapterView.getAdapter().getItem(position); String[] date = choiceDay.split(","); String day = date[1]; if (!" ".equals(day)) { if (Integer.parseInt(day) < 10) { day = "0" + date[1]; } choiceDay = date[0] + "-" + day; if (callBack != null) {//调用回调函数回调数据 callBack.onDaySelectListener(arg1, choiceDay); } } } }); } /** * 为gridview中添加需要展示的数据 * * @param tempSum * @param dayNumInMonth */ private void setGvListData(int tempSum, int dayNumInMonth, String YM) { if (gvList!=null){ gvList.clear(); for (int i = 0; i < tempSum; i++) { gvList.add(" , "); } for (int j = 1; j <= dayNumInMonth; j++) { gvList.add(YM + "," + String.valueOf(j)); } } } private String getMonth(int month) { String mon = ""; if (month < 10) { mon = "0" + month; } else { mon = "" + month; } return mon; } /** * 获取当前月的总共天数 * * @param cal * @return */ private int getDayNumInMonth(Calendar cal) { return cal.getActualMaximum(Calendar.DATE); } /** * 获取当前月第一天在第一个礼拜的第几天，得出第一天是星期几 * * @param cal * @return */ private int countNeedHowMuchEmpety(Calendar cal) { int firstDayInWeek = cal.get(Calendar.DAY_OF_WEEK) - 1; return firstDayInWeek; } public void setDefaultInView(int color,int textColor){ if (calAdapter!=null){ calAdapter.viewIn.setBackgroundColor(color); ((TextView)calAdapter.viewIn.findViewById(R.id.tv_calendar_day)).setTextColor(textColor); } } public void setDefaultOutView(int color,int textColor){ if (calAdapter!=null){ calAdapter.viewOut.setBackgroundColor(color); ((TextView)calAdapter.viewOut.findViewById(R.id.tv_calendar_day)).setTextColor(textColor); } } //监听是否点击接口 public interface OnDaySelectListener { void onDaySelectListener(View view, String date); } public void setOnDaySelectListener(OnDaySelectListener o) { callBack = o; } } 接下来是在Activity中实现绘制，由于我项目的需要只可以选择当前日期后90的时间，具 体看代码 public class MainActivity extends Activity implements OnDaySelectListener { private LinearLayout ll; private TextView cancel; private MyCalendar c1; private TextView toast; String nowday; long nd = 1000*24*60*60;//一天的毫秒数 SimpleDateFormat simpleDateFormat, formatYear, formatDay; SharedPreferences sp; SharedPreferences.Editor editor; private String inday,outday,sp_inday,sp_outday; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); sp=getSharedPreferences("date", Context.MODE_PRIVATE); //本地保存 sp_inday=sp.getString("dateIn", ""); sp_outday=sp.getString("dateOut", ""); editor=sp.edit(); simpleDateFormat=new SimpleDateFormat("yyyy-MM-dd"); nowday=simpleDateFormat.format(new Date()); formatYear =new SimpleDateFormat("yyyy"); formatDay =new SimpleDateFormat("dd"); initView(); init(); } private void initView() { ll=(LinearLayout) findViewById(R.id.ll); cancel= (TextView) findViewById(R.id.cancel); cancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { finish(); } }); toast= (TextView) findViewById(R.id.choose_toast); } private void init(){ List listDate=getDateList(); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); for(int i=0;i90){ return; } } catch (ParseException e) { e.printStackTrace(); } //若以前已经选择了日期，则在进入日历后会显示以选择的日期，该部分作用则是 重新点击日历时，清空以前选择的数据(包括背景图案) if(!"".equwww.sm136.comals(sp_inday)){ CalGridViewAdapter.viewIn.setBackgroundColor(Color.WHITE); ((TextView) CalGridViewAdapter.viewIn.findViewById(R.id.tv_calendar_day)).setTextColor(getResources().g etColor(R.color.color_default));
