我有问题,我想在我的数据库中插入时间戳。每次用户点击发送按钮时,显示的时间戳应该是用户点击按钮的时间。我在这里有代码:
btnSend.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String phoneNo = editTextRecipient.getText().toString();
String message = editTextNewMessage.getText().toString();
Log.d(phoneNo, message);
saveState(phoneNo, message, details);
boolean split = false;
SimpleDateFormat s = new SimpleDateFormat("ddMMyyyyhhmmss");
String date = s.format(new Date());
/*Bundle bundle = new Bundle();
bundle.putString(MessagesDBAdapter.KEY_RECIPIENT, editTextRecipient.getText().toString());
bundle.putString(MessagesDBAdapter.KEY_MESSAGE, editTextNewMessage.getText().toString());
bundle.putString(MessagesDBAdapter.KEY_DETAILS, tv_details.getText().toString());
if (mRowId != null) {
bundle.putLong(MessagesDBAdapter.KEY_ROWID, mRowId);
}*/
final Toast toast = Toast.makeText(getBaseContext(),
"Your message " + "\"" + message + "\"" + " is sent to " +"\""+ phoneNo+"\"",
Toast.LENGTH_SHORT);
Runnable showToastRunnable = new Runnable() {
public void run() {
dialog.cancel();
toast.show();
}
};
if (phoneNo.length()>0 && message.length()>0) {
showProgress();
if (count == 0) {
handler.postDelayed(showToastRunnable, 0);
}
else if (count == 1) {
handler.postDelayed(showToastRunnable, 15000);
}
else if (count == 2) {
handler.postDelayed(showToastRunnable, 30000);
}
else if (count == 3) {
handler.postDelayed(showToastRunnable, 60000);
}
}
// sendSMS(phoneNo, message, split); */
else
Toast.makeText(getBaseContext(),
"Please enter both phone number and message.",
Toast.LENGTH_SHORT).show();
}
});
mDbHelper.close();
}
private void populateFields() {
if (mRowId!=null) {
Cursor message=mDbHelper.fetchNote(mRowId);
startManagingCursor(message);
editTextRecipient.setText(message.getString(message.getColumnIndexOrThrow(MessagesDBAdapter.KEY_RECIPIENT)));
editTextNewMessage.setText(message.getString(message.getColumnIndexOrThrow(MessagesDBAdapter.KEY_MESSAGE)));
tv_details.setText(message.getString(message.getColumnIndexOrThrow(MessagesDBAdapter.KEY_DETAILS)));
}
}
private void saveState(String phoneNo, String message, String details) {
Log.i(phoneNo, message);
if (mRowId==null) {
mDbHelper.createNote(phoneNo, message, details);
}
}
时间戳应在24小时制显示(12:30等)。我做得对吗,我错过了什么?任何人都可以帮助我吗?

您可以使用Calendar课程。
Calendar now = Calendar.getInstance();
final int hour = now.get(Calendar.HOUR_OF_DAY);
final int minute = now.get(Calendar.MINUTE);
