android - 我如何从 EditText 中获取日期，然后将其存储在 Android 的数据库中

Question

我正在为用户输入用户输入他的出生日期使用编辑文本。 edittext 的输入类型是 Date，然后我将该日期传递给一个变量。该日期未传递给该变量并给出一些错误。

下面是我使用的代码

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那个日期需要什么类型。我的日志是:

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();

希望这对你有帮助...

谢谢...
