今天扣丁學(xué)堂Android培訓(xùn)老師為大家分享一篇關(guān)于Android實(shí)現(xiàn)app每月簽到功能的具體代碼，希望同學(xué)們對(duì)Android開(kāi)發(fā)有所幫助，下面我們一起來(lái)看一下吧。

先上一張效果圖：

其中這些簽到的效果圖是在網(wǎng)上找的，然后重要用到的控件就是GridvVew了，代碼很簡(jiǎn)單，只有3個(gè)代碼文件：

package zhanghuan.cn.checkdesign;
  
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.GridView;
import android.widget.TextView;
  
import java.util.ArrayList;
import java.util.Calendar;
import java.util.List;
import java.util.Locale;
  
public class MainActivity extends AppCompatActivity {
 private List<CheckBean> checkBeanList;
 private MyAdapter mAdapter;
 private GridView mGridview;
 private TextView monthTxt;
  
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  initDate();
 }
  
 private void initDate() {
  
  Calendar calendar = Calendar.getInstance(Locale.CHINA);
  int month = calendar.get(Calendar.MONTH) + 1;
  int day = calendar.getActualMaximum(Calendar.DATE); // 獲取當(dāng)前月的天數(shù)
  
  checkBeanList = new ArrayList<CheckBean>();
  for (int i = 0; i < day + 1; i++) {
   CheckBean checkBean = new CheckBean();
   if ((int) (Math.random() * 20 % 4) == 3) {
    checkBean.day = i;
    checkBean.check_status = CheckBean.CHECKED;
   } else if ((int) (Math.random() * 20 % 4) == 2) {
    checkBean.day = i;
    checkBean.check_status = CheckBean.CHECK_NO;
   } else {
    checkBean.day = i;
    checkBean.check_status = CheckBean.CHECK_WAIT;
   }
  
   checkBeanList.add(checkBean);
  }
  
  monthTxt = (TextView)findViewById(R.id.item_month);
  if (month < 1 || month > 12) {
   month = 1;
  }
  monthTxt.setText("當(dāng)前簽到月份是：" + month);
  
  mAdapter = new MyAdapter(MainActivity.this);
  mAdapter.setListDate(checkBeanList);
  
  mGridview = (GridView) findViewById(R.id.main_gridview);
  mGridview.setAdapter(mAdapter);
 }
}

適配器文件：MyAdapter.class

package zhanghuan.cn.checkdesign;
  
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
  
import java.util.List;
  
/**

 */
public class MyAdapter extends BaseAdapter {
 private Context mContext;
 private List<CheckBean> checkBeanList;
  
 public MyAdapter(Context context) {
  mContext = context;
 }
  
 public void setListDate(List<CheckBean> checklist) {
  checkBeanList = checklist;
 }
  
 @Override
 public int getCount() {
  return checkBeanList.size();
 }
  
 @Override
 public Object getItem(int position) {
  return checkBeanList.get(position);
 }
  
 @Override
 public long getItemId(int position) {
  return position;
 }
  
 @Override
 public View getView(final int position, View convertView, ViewGroup parent) {
  final MyHoder hoder;
  
  if (convertView == null) {
   convertView = LayoutInflater.from(mContext).inflate(R.layout.check_item, null);
   hoder = new MyHoder();
   hoder.day = (TextView) convertView.findViewById(R.id.item_day);
   hoder.status = (ImageView) convertView.findViewById(R.id.item_image);
   convertView.setTag(hoder);
  } else {
   hoder = (MyHoder) convertView.getTag();
  }
  
  hoder.day.setText("day" + checkBeanList.get(position).day);
  if (checkBeanList.get(position).check_status == CheckBean.CHECK_NO) {
   hoder.status.setImageResource(R.mipmap.check_no);
   hoder.status.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
     Toast.makeText(mContext, "恭喜你，簽到成功！", Toast.LENGTH_SHORT).show();
     hoder.status.setImageResource(R.mipmap.checked);
     hoder.status.setClickable(false);
     checkBeanList.get(position).check_status = CheckBean.CHECKED;
     /* 在此做一些簽到請(qǐng)求的處理 */
    }
   });
  } else if (checkBeanList.get(position).check_status == CheckBean.CHECK_WAIT) {
   hoder.status.setImageResource(R.mipmap.check_wait);
  } else if (checkBeanList.get(position).check_status == CheckBean.CHECKED) {
   hoder.status.setImageResource(R.mipmap.checked);
  }
  return convertView;
 }
  
 private static class MyHoder {
  TextView day;
  ImageView status;
 }
}

CheckBean.class文件：

package zhanghuan.cn.checkdesign;
  
import java.io.Serializable;
  
/**
 * Created by zhanghuan on 2016/3/8.
 */
public class CheckBean implements Serializable {
 // 根據(jù)自己的需求可以做補(bǔ)簽的字段設(shè)置
  
 public static final int CHECKED = 3; //已簽到
 public static final int CHECK_NO = 2; //沒(méi)有簽到
 public static final int CHECK_WAIT = 1; //等待簽到 （時(shí)間沒(méi)到無(wú)法簽到）
  
 public int day;
 public int check_status;
}
