時間選擇器以毫秒爲單位以毫秒爲單位計算出錯誤的值

Question

我正在使用時間選擇器將時間存儲在火力點 中，但時間選取器以毫秒爲單位選取錯誤的值。 如果我存儲時間03:02 pm它將存儲06:49:00。 如何使用時間選擇器獲得精確的毫秒數？

public class EditTimeTable extends BaseActivity { 

private EditText editTextaddress; 
private TextView textviewday; 
String day; 
//private Spinner spinnerDay; 
private Spinner spinnerSlot;

    Bundle bundle = getIntent().getExtras(); 
    day = bundle.getString("key", ""); 
    TextView TextViewday = (TextView) findViewById(R.id.post_day); 
    TextViewday.setText(day); 


    //getting the reference of drtime node 
    databasedrtime = FirebaseDatabase.getInstance().getReference(); 
    //getting views 

    editTextaddress = (EditText) findViewById(R.id.post_body);

       finish();

} 


private void writetimetable(String userId, String username, String address, String day, String slot, long time) { 
    // Create new post at /user-posts/$userid/$postid and at 
    // /posts/$postid simultaneously 
    String key = databasedrtime.child("Monday").getKey(); 
    drPost dr = new drPost(userId, username, address, day, slot, time); 
    Map<String, Object> postValues = dr.toMap(); 

    Map<String, Object> childUpdates = new HashMap<>(); 


    childUpdates.put("/user_time_table/" + userId + "/" + key, postValues); 

    databasedrtime.updateChildren(childUpdates); 
}

進入在adddrtime0）代碼（

Calendar calendar = Calendar.getInstance(); 
    int year = calendar.get(Calendar.YEAR); 
    int month = calendar.get(Calendar.MONTH); 
    final int days = calendar.get(Calendar.DAY_OF_MONTH); 
    int hour = 0; 
    int minute = 0; 

    int currentApiVersion = android.os.Build.VERSION.SDK_INT; 
    if (currentApiVersion > android.os.Build.VERSION_CODES.LOLLIPOP_MR1){ 
     hour = timePicker.getHour(); 
     minute = timePicker.getMinute(); 
    } else { 
     hour = timePicker.getCurrentHour(); 
     minute = timePicker.getCurrentMinute(); 
    } 
    calendar.set(year, month, days, hour, minute); 
    final long time = calendar.getTimeInMillis(); 

我收到時間選擇器值是我確切的選擇..
