先上一张效果图：

其中这些签到的效果图是在网上找的，然后重要用到的控件就是 GridvVew 了，代码很简单，只有3个代码文件：

MainActivity.class 文件

</pre><pre name="code" class="java">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); // 获取当前月的天数        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("当前签到月份是：" + month);        mAdapter = new MyAdapter(MainActivity.this);        mAdapter.setListDate(checkBeanList);        mGridview = (GridView) findViewById(R.id.main_gridview);        mGridview.setAdapter(mAdapter);    }}

适配器文件：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;/** * Created by zhanghuan on 2016/3/8. */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，签到成功！", Toast.LENGTH_SHORT).show();                    hoder.status.setImageResource(R.mipmap.checked);                    hoder.status.setClickable(false);                    checkBeanList.get(position).check_status = CheckBean.CHECKED;                    /* 在此做一些签到请求的处理 */                }            });        } 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 {    // 根据自己的需求可以做补签的字段设置    public static final int CHECKED = 3; //已签到    public static final int CHECK_NO = 2; //没有签到    public static final int CHECK_WAIT = 1; //等待签到 （时间没到无法签到）    public int day;    public int check_status;}
