I am making an app where I send data from one fragment to a dialog fragment
through a Bundle and pass that string with hash map and save that data to a database. When I send data from the fragment to the dialog fragment, it does not get there and I get the following error and my app crashes:
Attempt to invoke virtual method 'java.lang.String android.os.Bundle.getString(java.lang.String)' on a null object reference
Fragment code:
private void mobileNumber()
{
Bundle args = new Bundle();
args.putString("mobile", edtMobileNumber.getText().toString());
DialogFragment newFragment = new Save_contact_fragment();
newFragment.setArguments(args);
// newFragment.show(getFragmentManager(),"TAG");
}
In this code I am sending a mobile number to the dialog fragment. Dialog fragment code:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TokenModel mTokenModel = ((BaseActivity)getActivity()).getTokenDetails();
if (mTokenModel != null) {
mAuthorizationHeader = mTokenModel.getTokenType() + " " + mTokenModel.getAccessToken();
}
Bundle args = this.getArguments();
data = args.getString("mobile");
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.activity_save_contact, container, false);
initUI(view);
return view;
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
/*Bundle bundle = this.getArguments();
if (bundle == null) {
data = bundle.getString("mobile");
}*/
}
#Override
public void onDetach() {
super.onDetach();
}
private void initUI(View view) {
btnsave = (Button) view.findViewById(R.id.save);
btnCancelDialog = (Button) view.findViewById(R.id.btn_cancel);
etPromoCode = (EditText) view.findViewById(R.id.et_promo_code);
etPromoCode.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
if (charSequence.toString().length() > 0) {
btnsave.setEnabled(true);
} else {
btnsave.setEnabled(false);
}
}
#Override
public void afterTextChanged(Editable editable) {
}
});
// Should always be at the end
bindClicks();
}
private void bindClicks() {
btnsave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
callAddToContactAPI();
//Toast.makeText(getContext(), "save", Toast.LENGTH_SHORT).show();
//dismiss();
}
});
btnCancelDialog.setOnClickListener(new View.OnClickListener() {
#Override

}
});
}
private void callAddToContactAPI() {
if (selectedPlan == null) {
selectedPlan = new SaveContactModel();
//selectedPlan.setRemark(Constants.CATEGORY_MOBILE_RECHARGE);
//Toast.makeText(getContext(), "1", Toast.LENGTH_SHORT).show();
}
//selectedPlan.setPlanMrp(Integer.parseInt(Utils.getTextFromEditText(etPromoCode)));
addToContactAPI(selectedPlan);
}
private void addToContactAPI(SaveContactModel saveContactModel) {
if (!Utils.isNetworkConnected(getActivity())) {
return;
}
CartClient cartClient = ServiceGenerator.createService(CartClient.class);
HashMap<String, Object> parameterMap = new HashMap<>();
parameterMap.put(Constants.ADD_ContactName,Utils.getTextFromEditText(etPromoCode));
parameterMap.put(Constants.ADD_ContactNumber,data);
parameterMap.put(Constants.ADD_ServiceID_TO_SAVE, 1);
parameterMap.put(Constants.ADD_UserBasicID,"1593");
Call<String> cart = cartClient.addToContact(mAuthorizationHeader, parameterMap);
//Toast.makeText(getContext(), "2", Toast.LENGTH_SHORT).show();
String abc = cart.request().url().toString();
cart.enqueue(new Callback<String>() {
#Override
public void onResponse(Call<String> call, Response<String> response) {
if(response.code() == 200) {
Intent intent = new Intent(getContext(), MyContactActivity.class);
startActivity(intent);
Utils.showAlertDialogWithMessage(Constants.CONTACT_ADDED, getActivity());
// Utils.showAlertDialogWithMessage(Constants.SUCCESS_MESSAGE_ITEM_ADDED_TO_CART, getActivity());
} else {
// Utils.showAlertDialogWithMessage(Constants.ERROR_UNABLE_TO_PROCESS_REQUEST, getActivity());
}
}
#Override
public void onFailure(Call<String> call, Throwable t) {
Utils.showShortToastMessage(getActivity(), Constants.ERROR_OOPS_SOMETHING_WENT_WRONG);
}
});
}
Here is where I receive data in the dialog fragment:
Bundle args = this.getArguments();
data = args.getString("mobile");
But I get null and get an error when I pass that data string to a hash map. I do that in the following code:
HashMap<String, Object> parameterMap = new HashMap<>();
parameterMap.put(Constants.ADD_ContactName,Utils.getTextFromEditText(etPromoCode));
parameterMap.put(Constants.ADD_ContactNumber,data);
parameterMap.put(Constants.ADD_ServiceID_TO_SAVE, 1);
parameterMap.put(Constants.ADD_UserBasicID,"1593");
The mobile number is not there in the bundle.
put this part:
Bundle args = getArguments();
data = args.getString("mobile");
in onCreateView instead of onCreate and without this.
You can get your passed argument in onViewCreated or into onCreateView method. If you don't receive bundle, a default string will be used if arguments are different than null.
String mobile = getArguments() != null ? getArguments().getString("mobile", "defaultString") : "defaultString";

The problem is chatDialog.getUnreadMessageCount() giving me count 2 when I once enter in chat room and come back to my chat listing page.
Description on issue:-
Example:-
I have installed my application in two devices. when i send message from one (Device A) to other (Device B).The device B will display correct Unread count i.e 1 . Now when i click on chat dialog and get entered inside the chat room (of Device B). and come back to it's listing page and then again try to send message from Device A to device B . This time the unread count comes as 2 but it should be one as i already viewed my previous message. This get more worse if i try to open my chat room again to read the message(Device B) and get back to my listing page(Device B) after reading the message . This time if I send the message from Device A to Device B, Then the count came out as "5" just for my one message this thing is making me sick, I debugged the whole code, it's chatDialog .getUnreadMessageCount() who is returning me count "5", I don't know why my previous messages are not counted as being read messages and why everytime I open chat room one additional number gets added up inside the unread count.Please help me out , i am scratching my head from past two days.
Your help will be greatly Appreciated.
Thanks
Problem is that your AllDialogsMessageListener is not getting unregistered so unregister it by calling unregisterQbChatListeners(); when you will be opening your chat room screen . Every thing will work fine once you do that.
This what i mean :-
binding.listDialogsChats.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
QBChatDialog selectedDialog = (QBChatDialog) parent.getItemAtPosition(position);
if (currentActionMode == null) {
unregisterQbChatListeners();
ChatActivity.startForResult(((Activity) mContext), REQUEST_DIALOG_ID_FOR_UPDATE, selectedDialog);
} else {
dialogsAdapter.toggleSelection(selectedDialog);
}
}
});
private void unregisterQbChatListeners() {
if (incomingMessagesManager != null) {
incomingMessagesManager.removeDialogMessageListrener(allDialogsMessagesListener);
}
if (systemMessagesManager != null) {
systemMessagesManager.removeSystemMessageListener(systemMessagesListener);
}
dialogsManager.removeManagingDialogsCallbackListener(this);
}
cheers!!!
Please use this code below :
QBChatService.markMessagesAsRead("YOUR_DIALOG_ID", null, new QBEntityCallback<Void>() {
#Override
public void onSuccess(Void aVoid, Bundle bundle) {
QBRequestGetBuilder requestBuilder = new QBRequestGetBuilder();
requestBuilder.eq("_id", Team.getCurrent().getChatId());
QBChatService.getChatDialogs(null, requestBuilder, new QBEntityCallback<ArrayList<QBDialog>>() {
#Override
public void onSuccess(ArrayList<QBDialog> qbDialogs, Bundle bundle) {
if (qbDialogs != null && qbDialogs.size() > 0) {
QBDialog dialog = qbDialogs.get(0);//here you get your dialog with unreadMessageCount = 0
}
}
#Override
public void onError(QBResponseException e) {
}
});
}
#Override
public void onError(QBResponseException e) {
}
});
i want to query results from custom adapter by comparing query text with list in RecycleView, it successfully gets results from query then i make list of results and update the existing adapter but it does not effect anything, i use below code fot that
combinationMessagesList = createCombinationMessagesList();
combinationMessages = createCombinationMessagesList();
combinationMessages.clear();
for (int i = 0; i < combinationMessagesList.size(); i++) {
CombinationMessage message = combinationMessagesList.get(i);
if (message.getBody().toString().equals(search.getText().toString())){
combinationMessages.add(combinationMessagesList.get(i));
}
}
messagesAdapter.setList(combinationmessagesList);
messagesAdapter.notifyDataSetChanged();

it was my own mistake it code, i made the code work by changing messagesAdapter.setList(combinationmessagesList)
to

In my form fragment Hardware "back" button work not correctly. For example when I opened fragment and when I didn't start typing, and I pressed Hardware "back" button it's work excellent. But when I started typing and after typing press to Hardware "back" button app crashed without any error logs.

My form fragment is child fragment. And this parent fragment where I implement backaction.
#Override
public void onResume() {
super.onResume();
getView().setFocusableInTouchMode(true);
getView().requestFocus();
getView().setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK) {
backAction();
return true;
}
return false;
}
});
}
public void backAction() {
if (getChildFragmentManager().getBackStackEntryCount() > 0) {
getChildFragmentManager().popBackStack();
}
else {
((MainActivity) getActivity()).setCurrentItem(0, true);
}
}
Create TextWatcher like
TextWatcher textWatcher=new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
//TODO Auto-generated method stub
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable s) {
if(!s.toString().contains("+7 ")){
edt_phone.setText("+7 ");
Selection.setSelection(edt_phone.getText(), edt_phone.getText().length());
}
};
Add it to edt_phone like
edt_phone.addTextChangedListener(textWatcher);
Then in the back press event remove the listener,
getView().setOnKeyListener(new OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
edt_phone.removeTextChangedListener(textWatcher);
return true;
}
}
return false;
}
});
In your foam fragment(child fragment)
Communicator communicator;
#Override
public void onBackPressed() {
super.onBackPressed();
communicator.exitFragment();
}
public void setCommunicator(Communicator communicator)
{
this.communicator = communicator;
}
public interface Communicator
{
void exitFragment();
}
in your parent fragment do this
public parentFragment extends Fragment implements childFragment.Communicator
{
#override
public void onCreatView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
childFragment.setCommunicator(this);
}
public void exitFragment()
{
getActivity().finish();
}
}
Fragments are managed by the Fragment Managers which are called by the Activity; so, to control what you want to do when the back button is clicked, you must do that in the activity;
Now, if you have more than one fragment set, you should use tags to find them, check to see if they are visible and if so, do what you mentioned above.
When setting your fragments, you should give them a tag and then use this tag later to findFragmentByTagName() and do an if check to see which fragment is set at the moment;
Let me know if you need any clarification on the same.
I have a dialog that I want to display, and I cannot. The activity that I'm calling it from has an opengl es SurfaceViewRenderer. Some code is below. The text 'here' shows, and some of the activity from the fragment is going on in the background (I see some of the println statements from there) but no fragment is visible. I do not see 'is visible' in the logs.
public void goToFrag() {
dDial = new MYDialogFragment();
Bundle args = new Bundle();
dDial.setArguments(args);
dDial.show(getFragmentManager(), "dDialog");
if (dDial.isVisible() ) System.out.println("is visible");
System.out.println("here");
}
so here's some more info. I tried to run the 'goToFrag()' method from the 'runOnUIThread()' method and the fragment appears, but only for a second. Then the PlayActivity (what I'm calling the activity that launches the Fragment and contains the GLSurfaceRenderer) disappears. After that I'm back at the activity that calls the PlayActivity. There's no error output that I can find.
//from OpenGL SurfaceViewRenderer...
public void goToFrag() {
mPlayActivity.runOnUiThread(new Runnable() {
#Override
public void run() {
mPlayActivity.goToFrag();
}
});
}
