一：实现功能
1：创建待办事项的显示与完成待办事项时的显示
2:搜索已经存在的代办事项
3：日历（阳历阴历转换）
代码如下：
MainActivity.java如下：
public class MainActivity extends AppCompatActivity {

private Button btn_List,btn_Calendar,btn_Complete;
private static EditText InputContent, SearchContent,SerialNumber,SearchSerialNumber;
private static EditText GetContent,GetSerialNumber,GetContent1,GetSerialNumber1,GetContent2,GetSerialNumber2;

});
//用于添加待办事项

}

}
count++;
if (count > 3)
Toast.makeText(MainActivity.this,"待办事项存在太多了，请做完一些在添加吧！",Toast.LENGTH_SHORT).show();
Log.d("Count",count+"");
Log.d(Dao.TAG,ID);
Log.d(Dao.TAG,Content);
//清除数据库专用
//for (int i = 0; i< 50;i++)
//dao.Delete(i+"");
// setListen();
}
});
//（可见不可见占位置，只是消失，隐藏不会占据屏幕位置）
//如果被选择就使checkbox,序号，EditText三个为隐藏,并传到另一个一个页面
//用于提交待办事项（表示已完成）
btn_Complete.setOnClickListener(new View.OnClickListener() {
@Override
