java - 如何将当前时间与Android中存储在数据库中的时间进行比较

Question

如何将当前日期与数据库中存储的值进行比较？目前我的代码如下所示:

final String dDate = cursor.getString(cursor.getColumnIndex(cursor.getColumnName(4)));
final String dTime = cursor.getString(cursor.getColumnIndex(cursor.getColumnName(5)));
Calendar calendar1 = Calendar.getInstance();
SimpleDateFormat formatter1 = new SimpleDateFormat("dd/M/yyyy");
String currentDate = formatter1.format(calendar1.getTime());

Calendar calendar2 = Calendar.getInstance();
SimpleDateFormat formatter2 = new SimpleDateFormat("h:mm");
String currentTime = formatter2.format(calendar2.getTime());
if(currentDate.compareTo(dDate)>=0) {
  if (currentDate.equals(currentDate)) {
    if (currentTime.compareTo(dTime) > 0) {
      myCheckBox.setChecked(true);
      myCheckBox.setEnabled(false);
    }
  }
}

此代码有效。查看

Calendar calendar1 = Calendar.getInstance();
SimpleDateFormat formatter1 = new SimpleDateFormat("dd/M/yyyy h:mm");
String currentDate = formatter1.format(calendar1.getTime());

final String dateString = cursor.getString(4);
final String timeString = cursor.getString(5);
String datadb =dateString+" "+timeString;

//  Toast.makeText(context,"databse date:-"+datadb+"Current Date :-"+currentDate,Toast.LENGTH_LONG).show();

if(currentDate.compareTo(datadb)>=0) {
    myCheckBox.setChecked(true);
    myCheckBox.setEnabled(false);
}
