Android实现点击签到按钮直接签到，弹出dialog，先上效果图

demo是利用gridview实现的,现附上布局文件

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="2dp" android:orientation="vertical" android:background="@drawable/shape_btn_white" > <RelativeLayout android:layout_width="match_parent" android:layout_height="40dp" > <ImageView android:id="@+id/iv_front" android:layout_width="30dp" android:layout_height="40dp" android:padding="10dp" android:layout_marginLeft="8dp" android:scaleType="centerCrop" android:layout_alignParentLeft="true" android:layout_centerInParent="true" android:src="@mipmap/icon_sign_front" /> <TextView android:id="@+id/tv_date" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:textColor="#2fbbef" android:textSize="15sp" android:text="2016-7-16" /> <ImageView android:id="@+id/iv_next" android:layout_width="30dp" android:layout_height="40dp" android:layout_marginRight="8dp" android:padding="10dp" android:scaleType="centerCrop" android:layout_alignParentRight="true" android:layout_centerInParent="true" android:src="@mipmap/icon_sign_next" /> </RelativeLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="40dp" > <TextView android:layout_width="40dp" android:layout_height="40dp" android:layout_weight="1" android:gravity="center" android:text="日" android:textSize="15sp" android:textColor="#888" /> <TextView android:layout_width="40dp" android:layout_height="40dp" android:layout_weight="1" android:gravity="center" android:text="一" android:textSize="15sp" android:textColor="#888" /> <TextView android:layout_width="40dp" android:layout_height="40dp" android:layout_weight="1" android:gravity="center" android:text="二" android:textSize="15sp" android:textColor="#888" /> <TextView android:layout_width="40dp" android:layout_height="40dp" android:layout_weight="1" android:gravity="center" android:text="三" android:textSize="15sp" android:textColor="#888" /> <TextView android:layout_width="40dp" android:layout_height="40dp" android:layout_weight="1" android:gravity="center" android:text="四" android:textSize="15sp" android:textColor="#888" /> <TextView android:layout_width="40dp" android:layout_height="40dp" android:layout_weight="1" android:gravity="center" android:text="五" android:textSize="15sp" android:textColor="#888" /> <TextView android:layout_width="40dp" android:layout_height="40dp" android:layout_weight="1" android:gravity="center" android:text="六" android:textSize="15sp" android:textColor="#888" /> </LinearLayout> <GridView android:id="@+id/gv_sign_date" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="#dbdbdb" android:clickable="true" android:clipChildren="true" android:columnWidth="30dp" android:listSelector="@null" android:numColumns="7" android:paddingBottom="1dp" android:stretchMode="columnWidth" android:verticalSpacing="1dp" ></GridView> <TextView android:layout_width="match_parent" android:layout_height="1dp" android:background="#dbdbdb" /> <LinearLayout android:layout_width="match_parent" android:layout_height="50dp" android:gravity="center" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="连续签到会有更多积分哦 !" android:textColor="#2a2a2a" android:layout_marginRight="5dp" android:textSize="14sp" /> <TextView android:id="@+id/tv_sign_num" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="20dp" android:visibility="gone" android:text="3天" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/jifen" android:textColor="#2a2a2a" android:visibility="gone" android:layout_marginRight="5dp" android:textSize="14sp" /> <TextView android:id="@+id/tv_jifen_num" android:visibility="gone" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="100" /> </LinearLayout> </LinearLayout> </LinearLayout>

效果图:

dialog中的主要代码:

public class SignDataDialog extends Dialog implements View.OnClickListener{ private GridView gridView; private ImageView iv_front,iv_next; private TextView tv_date,tv_sign_days,tv_jifen; private MyCalendarAdapter adapter; private SpecialCalendar sp; private Context context; private SignDateModle modle; private SimpleDateFormat sdf = new SimpleDateFormat("yyyy-M-d"); private String systime; private int year,month; String[] b=new String[]{ "0","0","0","0","0","0","0", "0","0","0","0","0","0","0", "0","0","0","0","0","0","0", "0","0","0","0","0","0","0", "0","0","0","0","0","0","0", "0","0","0","0","0","0","0" }; public SignDataDialog(Context context,SignDateModle modle) { super(context); this.context=context; this.modle=modle; setContentView(R.layout.dialog_sign_data); Window window = getWindow(); WindowManager.LayoutParams params = window.getAttributes(); params.gravity = Gravity.CENTER; window.setBackgroundDrawableResource(android.R.color.transparent); window.setAttributes(params); setCanceledOnTouchOutside(true); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); sp=new SpecialCalendar(); Date date = new Date(); systime = sdf.format(date); year=Integer.valueOf(systime.split("-")[0]); month=Integer.valueOf(systime.split("-")[1]); iv_front= (ImageView) findViewById(R.id.iv_front); iv_next= (ImageView) findViewById(R.id.iv_next); gridView= (GridView) findViewById(R.id.gv_sign_date); tv_date= (TextView) findViewById(R.id.tv_date); tv_sign_days= (TextView) findViewById(R.id.tv_sign_num); tv_jifen= (TextView) findViewById(R.id.tv_jifen_num); tv_date.setText(systime); iv_front.setOnClickListener(this); iv_next.setOnClickListener(this); if (modle!=null) { String dates=modle.getDateTime(); adapter = new MyCalendarAdapter(context, Integer.valueOf(dates.split("-")[0]), Integer.valueOf(dates.split("-")[1]), 17, getStrings(modle)); gridView.setAdapter(adapter); } } public String[] getStrings(SignDateModle modle){ int year=Integer.valueOf(modle.getDateTime().split("-")[0]); int moth=Integer.valueOf(modle.getDateTime().split("-")[1]); int start=sp.getWeekdayOfMonth(year,moth); for (int i=0;i<modle.getDatas().size();i++){ if (modle.getDatas().get(i).getStatus()==1){ b[i]=String.valueOf(1); } } return b; } @Override public void onClick(View v) { switch (v.getId()){ case R.id.iv_front: redMonth(); tv_date.setText(year+"-"+month+"-"+systime.split("-")[2]); changeOtherMoth(year, month); break; case R.id.iv_next: addMonth(); tv_date.setText(year+"-"+month+"-"+systime.split("-")[2]); changeOtherMoth(year,month); break; } } public void addMonth(){ month++; if (month==13){ month=1; year++; } } public void redMonth(){ month--; if (month==0){ month=12; year--; } } public void changeOtherMoth(int year,int moth){ if (CMethod.isNet(context)){ JSONObject jsonObject= NetJsonModle.getJsonObject(context,"528"); try { jsonObject.put("reporterId",new LastLoginUtils(context).getReporterId()); jsonObject.put("time", year + "-" + moth); HttpUtils.PostDataToWeb(UrlAddressUrils.CODE_OTHER, AppConstants.SIGN_DATA_INFO, jsonObject, new HttpClientListener() { @Override public void onSuccess(String result) { Gson gson = new Gson(); SignDateModle m = gson.fromJson(result, SignDateModle.class); for (int i = 0; i < b.length; i++) { b[i] = "0"; } if (m != null) { String dates = m.getDateTime(); adapter = new MyCalendarAdapter(context, Integer.valueOf(dates.split("-")[0]), Integer.valueOf(dates.split("-")[1]), 17, getStrings(m)); gridView.setAdapter(adapter); } } @Override public void onFailure(String result) { } @Override public void onError() { } }); } catch (JSONException e) { e.printStackTrace(); } }else { T.s("请检查网络是否连接"); } }

其计算日期的主要代码在适配器中:

class MyCalendarAdapter extends BaseAdapter{ private boolean isLeapyear = false; // 是否为闰年 private int daysOfMonth = 0; // 某月的天数 private int dayOfWeek = 0; // 具体某一天是星期几 private int lastDaysOfMonth = 0;

private int currentFlag = -1; // 用于标记当天 private String showYear = ""; // 用于在头部显示的年份 private String showMonth = ""; // 用于在头部显示的月份 private String animalsYear = ""; private String leapMonth = ""; // 闰哪一个月 // 系统当前时间 private String sysDate = ""; private String sys_year = ""; private String sys_month = ""; private String sys_day = ""; private boolean flag;// 标记是不是本月 private String[] data; private int a; public MyCalendarAdapter() { Date date = new Date(); sysDate = sdf.format(date); // 当期日期 sys_year = sysDate.split("-")[0]; sys_month = sysDate.split("-")[1]; sys_day = sysDate.split("-")[2]; } public MyCalendarAdapter(Context context,int year_c,int month_c, int day_c, String[] a) { // TODO Auto-generated constructor stub this(); this.context = context; sc = new SpecialCalendar(); currentYear = String.valueOf(year_c);// 得到当前的年份 currentMonth = String.valueOf(month_c); getCalendar(Integer.parseInt(currentYear), Integer.parseInt(currentMonth)); data = a; } @Override public int getCount() { return dayNumber.length; } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position;

} setShowYear(String.valueOf(year)); setShowMonth(String.valueOf(month)); } else { // 下一个月 dayNumber[i] = j + ""; j++; } } String abc = ""; for (int i = 0; i < dayNumber.length; i++) { abc = abc + dayNumber[i] + ":"; } } public String getShowYear() { return showYear; } public void setShowYear(String showYear) { this.showYear = showYear; } public String getShowMonth() { return showMonth; } public void setShowMonth(String showMonth) { this.showMonth = showMonth; } public String getAnimalsYear() { return animalsYear; } public void setAnimalsYear(String animalsYear) { this.animalsYear = animalsYear; } public String getLeapMonth() { return leapMonth; } public void setLeapMonth(String leapMonth) { this.leapMonth = leapMonth;
