我正在使用用户输入的edittext,用户输入了他的出生日期。 edittext的输入类型是Date,然后我将该日期传递给变量。该日期不会传递给该变量并给出一些错误。
我正在使用的代码在
之下Edit dob=(EditText)findViewById(R.id.dob);
SimpleDateFormat sdf = new SimpleDateFormat( "yyyy/MM/dd" );
String dob_var=sdf.format(dob.getText());
//dob_var=dob.getText().toString();
System.out.println(dob_var);
之后我想在数据库中传递那个日期,那么在数据库中存储该日期的类型是什么。 我的logcat是:

终于明白了,
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy"); // Make sure user insert date into edittext in this format.
Date dateObject;
try{
String dob_var=(tx.getText().toString());
dateObject = formatter.parse(dob_var);
date = new SimpleDateFormat("dd/MM/yyyy").format(dateObject);
time = new SimpleDateFormat("h:mmaa").format(dateObject);
}
catch (java.text.ParseException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
Log.i("E11111111111", e.toString());
}
Toast.makeText(getBaseContext(), date + time, Toast.LENGTH_LONG).show();
希望这会对你有帮助......
...谢谢

首先,您需要将edittext的字符串转换为日期:
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
Date dob_var = sdf.parse(dob.getText());
现在将 dob_var 转换为sqlite标准日期字符串:
DateFormat dateFormatISO8601 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String strDob = dateFormatISO8601.format(dob_var);
/* save strDob into database */
答案 2 :(得分:3)
尝试
String dob_var=sdf.format(dob.getText().toString().trim());
