How can i get the date from the EditText and then store it in database in Android

问题:

i am using an edittext for the user input in which user entered his Date of birth. The input type of the edittext is Date and then i am passing that date to a variable. That date is not passed to that variable and giving some error.

The code i am using is below

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); 

After that i want to pass that date in database so what is the type require to store that date in database. My logcat is:

Finally got it,

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(); 

Hope this will help you...

Thanks...

First you need to convert your edittext's string into date:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd"); Date dob_var = sdf.parse(dob.getText()); 

now convert dob_var into sqlite standard date string:

DateFormat dateFormatISO8601 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String strDob = dateFormatISO8601.format(dob_var);  /* save strDob into database */

try with

 String dob_var=sdf.format(dob.getText().toString().trim());
