Return Back the Data from the Activity who calls the fragment dialog

I have a code that calls a fragment as an activity. From that fragment I select a data then give it back to the activity caller and here is my code.
Heres how I open the dialog
fragment_customer_list dialog = new fragment_customer_list();
dialog.show(getFragmentManager(),"CustomerList");
And here is how I return the value
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView position1 = (TextView) view.findViewById(R.id.list_name);
TextView position2 = (TextView) view.findViewById(R.id.list_address);
String customer_name = position1.getText().toString();
String customer_address = position2.getText().toString();
add callingActivity = (add_activity ) getActivity();
callingActivity.onUserSelectValue(customer_name, customer_address);
getDialog().dismiss();
}
});
I will call a function from the activity that calls the dialog to update the edittext.
public void onUserSelectValue(String selectedValue1 ,String selectedValue2) {
//Toast.makeText(getBaseContext(), ""+ selectedValue1 + selectedValue2, Toast.LENGTH_LONG).show();
EditText customer_name = (EditText) findViewById(R.id.cusname);
customer_name.setText(selectedValue1);
EditText customer_address = (EditText) findViewById(R.id.address);
customer_address.setText(selectedValue2);
}
The problem is the dialog is fixed in one activity. My question is how can I return the data from the activity caller? Since this fragment will be used by many activity
============================updated=============================
Here is how I open my fragment and i open it as a dialog
/* Open Customer List */
final EditText show_customer_list = (EditText) findViewById(R.id.cusname);
show_customer_list.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
fragment_customer_list dialog = new fragment_customer_list();
dialog.setOnClickItemListener(new fragment_customer_list.OnClickItemListener()
{
#Override
public void value(String name, String address)
{
show_customer_list.setText(name + " " + address);
}
});
dialog.show(getFragmentManager(),"CustomerList");
}
});
And here is the whole code fragment_customer_list
public class fragment_customer_list extends DialogFragment {
private static final String TAG = "CustomerList";
DatabaseHelper myDb;
String pattern_email;
SimpleAdapter adapter;
private DialogInterface.OnClickListener listener;
private OnClickItemListener mListener;
#Nullable
#Override
public View onCreateView(final LayoutInflater inflater, #Nullable final ViewGroup container, Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.fragment_customer_list, container, false);
final ListView listView = (ListView) view.findViewById(R.id.customer_list);
myDb = new DatabaseHelper(getActivity());
pattern_email = credentials.email;
final ArrayList<String> result = new ArrayList<>();
Cursor data = myDb.get_customer(pattern_email);
if (data.getCount() == 0) {
Toast.makeText(getActivity(), "Please sync to check your customers", Toast.LENGTH_LONG).show();
} else {
List<Map<String, String>> data1 = new ArrayList<Map<String, String>>();
while (data.moveToNext()) {
Map<String, String> datum = new HashMap<String, String>(2);
datum.put("Customer Name", data.getString(1));
datum.put("Address", data.getString(2));
data1.add(datum);
}
adapter = new SimpleAdapter(getActivity(), data1,
R.layout.customer_listview,
new String[]{"Customer Name", "Address"},
new int[]{R.id.list_name,
R.id.list_address});
listView.setAdapter(adapter);
}
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView position1 = (TextView) view.findViewById(R.id.list_name);
TextView position2 = (TextView) view.findViewById(R.id.list_address);
String customer_name = position1.getText().toString();
String customer_address = position2.getText().toString();
// add_activity callingActivity = (add_activity ) getActivity();
// callingActivity.onUserSelectValue(customer_name, customer_address);
if (mListener != null) {
mListener.value(customer_name, customer_address);
}
getDialog().dismiss();
}
});
android.widget.Button clickButton = (android.widget.Button) view.findViewById(R.id.close);
clickButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getDialog().dismiss();
}
});
/* Search customer */
EditText customer_search = (EditText) view.findViewById(R.id.search_customer);
customer_search.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
final ArrayList<String> result = new ArrayList<>();
Cursor data = myDb.get_customer_search(cs.toString(),pattern_email);
if (data.getCount() == 0) {
//Toast.makeText(getActivity(), "Please sync to check your customers", Toast.LENGTH_LONG).show();
} else {
List<Map<String, String>> data1 = new ArrayList<Map<String, String>>();
while (data.moveToNext()) {
Map<String, String> datum = new HashMap<String, String>(2);
datum.put("Customer Name", data.getString(1));
datum.put("Address", data.getString(2));
data1.add(datum);
}
adapter = new SimpleAdapter(getActivity(), data1,
R.layout.customer_listview,
new String[]{"Customer Name", "Address"},
new int[]{R.id.list_name,
R.id.list_address});
listView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { }
#Override
public void afterTextChanged(Editable arg0) {
}
});
return view;
}
#NonNull
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
return new Dialog(getActivity(), R.style.WideDialog);
}
public void setOnClickItemListener(OnClickItemListener l) {
mListener = l;
}
interface OnClickItemListener {
void value(String name, String address);
}
}
As you can see on the code above there is Listview that has a code that same as this
add_activity callingActivity = (add_activity ) getActivity();
callingActivity.onUserSelectValue(customer_name, customer_address);
getDialog().dismiss();
The code above will get the value from listview and call the onUserSelectValue from add_activity then close the dialog
and this is onUserSelectValue and it is located at add_activity
public void onUserSelectValue(String selectedValue1 ,String selectedValue2) {
//Toast.makeText(getBaseContext(), ""+ selectedValue1 + selectedValue2, Toast.LENGTH_LONG).show();
EditText customer_name = (EditText) findViewById(R.id.cusname);
customer_name.setText(selectedValue1);
EditText customer_address = (EditText) findViewById(R.id.address);
customer_address.setText(selectedValue2);
}
Here is my question.
How can I return the value of the listview to the textfield of the activity who opens the fragment(where the list view is located).
UPDATED CODE
I created a class called DialogHelper.java and this is the code
public class DialogHelper {
private static WeakReference<fragment_customer_list> wr;
public static void userSelectValue(Activity context, fragment_customer_list.OnClickItemListener listener) {
if (wr == null || wr.get() == null) {
fragment_customer_list dialog = new fragment_customer_list();
wr = new WeakReference<>(dialog);
}
fragment_customer_list dialog = wr.get();
dialog.OnClickItemListener(listener);
dialog.show(context.getFragmentManager(),"CustomerList");
}
// dialog dismiss
public static void dismiss() {
if (wr == null || wr.get() == null) return;
wr.get().dismiss();
}
}
In my customer_fragment_list.java I have a listview listener
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView position1 = (TextView) view.findViewById(R.id.list_name);
TextView position2 = (TextView) view.findViewById(R.id.list_address);
TextView position3 = (TextView) view.findViewById(R.id.list_code);
String customer_name = position1.getText().toString();
String customer_address = position2.getText().toString();
String customer_code = position3.getText().toString();
if (listener != null) {
listener.click(customer_name, customer_address,customer_code );
}
}
});
together with this
public void setOnClickListener(OnClickListener l) {
this.listener = l;
}
interface OnClickListener {
void click(String name, String address,String KUNNR);
}
public interface OnClickItemListener { void value(String name, String address, String code); }
and on my Activity this the code on how i open the dialog
/* Open Customer List */
DialogHelper.userSelectValue(add_covplan.this, new fragment_customer_list.OnClickItemListener()
{
#Override
public void value(String name, String address)
{
EditText customer_name = (EditText) findViewById(R.id.cusname);
customer_name.setText(name);
EditText customer_address = (EditText) findViewById(R.id.address);
customer_address.setText(address);
}
});

you can do this. Don't know if you mean this?
public class DialogHelper {
private static WeakReference<fragment_customer_list> wr;
private static WeakReference<Activity> wrActivity;
public static void userSelectValue(Activity context, fragment_customer_list.OnClickItemListener listener) {
if (wr == null || wr.get() == null || wrActivity == null || wrActivity.get() == null || wrActivity.get() != context) {
fragment_customer_list dialog = new fragment_customer_list();
wr = new WeakReference<>(dialog);
wrActivity = new WeakReference<>(context);
}
fragment_customer_list dialog = wr.get();
dialog.setOnClickItemListener(listener);
dialog.show(context.getFragmentManager(),"CustomerList");
}
// dialog dismiss
public static void dismiss() {
if (wr == null || wr.get() == null || !wr.get().isShowing()) return;
wr.get().dismiss();
}
}
use
final EditText show_customer_list = (EditText) findViewById(R.id.cusname);
DialogHelper.userSelectValue(this, new fragment_customer_list.OnClickItemListener()
{
#Override
public void value(String name, String address)
{
show_customer_list.setText(name + " " + address);
}
});
edit answer
// Suppose this is a FragmentDialog
public class FragmentList {
private OnClickListener listener;
private ListView listView;
// Suppose this has your list listener
public void onResume() {
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView position1 = (TextView) view.findViewById(R.id.list_name);
TextView position2 = (TextView) view.findViewById(R.id.list_address);
String customer_name = position1.getText().toString();
String customer_address = position2.getText().toString();
if (listener != null) {
listener.click(customer_name, customer_address);
}
}
});
}
public void setOnClickListener(OnClickListener l) {
this.listener = l;
}
interface OnClickListener {
void click(String name, String address);
}
}
// Suppose this is a Activity
class YourActivity extends Activity
{
private FragmentList fragmentList;
EditText customer_address;
EditText customer_name;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
fragmentList = new FragmentList();
customer_address = (EditText) findViewById(R.id.address);
customer_name = (EditText) findViewById(R.id.cusname);
fragmentList.setOnClickListener(new FragmentList.OnClickListener()
{
#Override
public void click(String name, String address)
{
// ...
customer_name.setText(name);
customer_address.setText(address);
}
});
}
}

You can use a ViewModel class implementation to share resources between Activity and Fragment. Share the single context across multiple usages of ViewModel, each sharing a the same ViewModel. It works with the observer and observable pattern and perfect for this use case. You can check details on how to implement it here

Fragment listview last value is not disappear

I have listview All the values are delete and update properly but only the last value is not delete in the listview.
Added a full fragment code. Take a look
For example
If I have three values in the listview If I delete 1 and 2 its removing and listview refresh properly but the last one is not refreshed in the listview

you have to tell your ListView that something changed in it's former List by calling notifyDataSetChanged() method of your adapter
Also you should not create a new instance of ArrayList, but only clear the old instance. Don't forget to check for null before clearing.

try calling the adapter again with a null like.
setListAdapter()

Android Listview opens to another listview

I have currently implemented a listview, which when you click an item opens a second activity. In the second activity I have another listview which i can add items to, but when i go back to the first list and click another item, all the items from the second list appear for this one as well.
Any ideas how to sort this out? Can post code if needed
Here is the code for the first activity:
public class MainActivity extends Activity {
private ArrayList<String> entries;
private ArrayAdapter<String> entriesAdapter;
private ListView list;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
createListView();
createListViewListener();
}
private void createListView() {
list = (ListView) findViewById(R.id.diaryListView);
entries = new ArrayList<>();
readEntries();
entriesAdapter = new CustomAdapter(this, entries);
list.setAdapter(entriesAdapter);
}
private void createListViewListener() {
list.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
entries.remove(position);
entriesAdapter.notifyDataSetChanged();
writeEntries();
return true;
}
});
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
intent.putExtra("entry", entries.get(position));
startActivity(intent);
}
});
}
public void addEntry(View v) {
EditText entryEditText = (EditText) findViewById(R.id.entryEditText);
String diaryText = entryEditText.getText().toString();
entriesAdapter.add(diaryText);
entryEditText.setText("");
writeEntries();
}
private void readEntries() {
File filesDir = getFilesDir();
File journalEntriesFile = new File(filesDir, "journalEntries.txt");
try {
entries = new ArrayList<>(FileUtils.readLines(journalEntriesFile));
} catch (IOException e) {
entries = new ArrayList<>();
}
}
/**
* Method to save a list of tasks
*/
private void writeEntries() {
File filesDir = getFilesDir();
File journalEntriesFile = new File(filesDir, "journalEntries.txt");
try {
FileUtils.writeLines(journalEntriesFile, entries);
} catch (IOException e) {
e.printStackTrace();
}
}
and the second:
public class SecondActivity extends Activity {
private String entryName;
private TextView entryTitle;
private ArrayList<String> entryTask;
private ArrayAdapter<String> entryTaskAdapter;
private ListView entryTaskList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
displayEntryTitle();
createEntryTaskListView();
createEntryTaskListViewListener();
}
private void displayEntryTitle() {
entryTitle = (TextView) findViewById(R.id.entryTitle);
Intent intent = getIntent();
entryName = intent.getStringExtra("entry");
entryTitle.setText("" + entryName);
}
private void createEntryTaskListView() {
entryTaskList = (ListView) findViewById(R.id.entryTaskListView);
entryTask = new ArrayList<>();
readEntryTasks();
entryTaskAdapter = new CustomAdapter2(this, entryTask);
entryTaskList.setAdapter(entryTaskAdapter);
}
private void createEntryTaskListViewListener() {
entryTaskList.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
entryTask.remove(position);
entryTaskAdapter.notifyDataSetChanged();
writeEntryTasks();
return true;
}
});
entryTaskList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, final int position, long id) {
View view2 = (LayoutInflater.from(SecondActivity.this)).inflate(R.layout.alert_dialog, null);
AlertDialog.Builder alertBuilder = new AlertDialog.Builder(SecondActivity.this);
alertBuilder.setTitle("Edit Journal Task Entry");
alertBuilder.setView(view2);
final EditText editEntryTaskText = (EditText) view2.findViewById(R.id.editEntryTask);
alertBuilder.setCancelable(true).setPositiveButton("Edit", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
String editEntry = editEntryTaskText.getText().toString();
editEntryTaskText.setText("" + editEntry);
}
});
Dialog dialog = alertBuilder.create();
dialog.show();
}
});
}
public void onAddEntryTask(View v) {
EditText editText = (EditText) findViewById(R.id.entryTaskEditText);
String entryTaskText = editText.getText().toString();
entryTaskAdapter.add(entryTaskText);
editText.setText("");
writeEntryTasks();
}
private void readEntryTasks() {
File filesDir = getFilesDir();
File taskEntriesFile = new File(filesDir, "taskEntries.txt");
try {
entryTask = new ArrayList<>(FileUtils.readLines(taskEntriesFile));
} catch (IOException e) {
entryTask = new ArrayList<>();
}
}
private void writeEntryTasks() {
File filesDir = getFilesDir();
File taskEntriesFile = new File(filesDir, "taskEntries.txt");
try {
FileUtils.writeLines(taskEntriesFile, entryTask);
} catch (IOException e) {
e.printStackTrace();
}
}

Without seeing how you get back to the first activity from the second activity I can only assume that ArrayList entrytask is getting inserted into ArrayList entries when you return so based on the limited information I have the best answer I can come up with is
private void createListView() {
list = (ListView) findViewById(R.id.diaryListView);
entries = new ArrayList<>();
list.setAdapter(null);
//ArrayList<String> entries = null;
readEntries();
entriesAdapter = new CustomAdapter(this, entries);
list.setAdapter(entriesAdapter);
}

pass data from fragment inside view pager to another activity

i hope you guys can help me. it`s drivin me crazy find the solution...
i already read some question that similar with my problems, but none solved mine.
here`s the problems
1 have 2 activity...
first --> i have activity that contain a view pager which hold 3 tab fragment.
in this first activity i extends with fragmentActivity
and here the code
public class A_BonRokok_Add_Main_Paged extends FragmentActivity {
private static final String[] CONTENT = new String[] { "Header", "Item", "Info"};
MainActivity main = new MainActivity();
FragmentManager manager;
FragmentTransaction transaction;
Dialog alert;
LayoutInflater li;
LinearLayout someLayout;
Button btnSave_dialog;
Button btnCancel_dialog;
public EditText search;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.l_bon_rokok_add_main_paged);
FragmentPagerAdapter adapter = new MyAdapter(getSupportFragmentManager());
ViewPager pager = (ViewPager)findViewById(R.id.pager);
pager.setAdapter(adapter);
TabPageIndicator indicator = (TabPageIndicator)findViewById(R.id.indicator);

Very old question, but no answer. I'm sure you have found a fix by now, but anyway.
You're changing the songs list object in background, and if Android decides to redraw your list (user scrolls your list), effectively accessing the songs list object, it may have changed and cause this exception to be thrown.
You need to use a temporary songs list and create a new adapter with it to update your list, thus not changing the current adapter list until you set a new adapter from the main UI thread.
