如何从EditText获取日期,然后将其存储在Android的数据库中

我正在使用edittext作为用户输入的用户输入他的出生日期. edittext的输入类型是Date,然后我将该日期传递给变量.该日期未传递给该变量并给出一些错误.

我正在使用的代码如下

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该日期,以便将该日期存储在数据库中的类型是什么.
我的logcat是：

解决方法:

终于搞定了,

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();

希望对你有帮助…

谢谢…
