saving and getting spinner items with shared preferences

I have a problem with saving spinner items to shared preferences. By problem I mean I really don't know how to do it. It would be nice if someone could actually explain it to me if someone knows.Thanks in advance :)
so I have set my button 1 to open a dialog with spinner and in spinner i have 3 items (declared in strings.xml). I should use shared preferences to set spinner to item 1 :"-" by default, and if user selects item 2 "lang1" or "lang2" it should be saved in app. So that when i open app next time its on "lang1" or "lang2" depends on selection.
Everything else is working fine.
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
SharedPreferences sharedpreferences;
public static final String mypreference = "mypref";
int spinnerPosition;
public Button btnTrans, btnSelect,btnInput,btnCheck;
public TextView tv_title, tv_message;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnSelect= (Button) findViewById(R.id.btnLanguage);
btnInput = (Button) findViewById(R.id.btnInput);
btnTrans = (Button) findViewById(R.id.btnTranslate);
btnTrans.setOnClickListener((View.OnClickListener) this);
btnInput.setOnClickListener(this);
btnSelect.setOnClickListener(this);
Spinner lang_spinner = (Spinner) findViewById(R.id.lang_spinner);
}
public void onClick(View v)
{
int id=v.getId();
switch (id){
case R.id.btnLanguage:
AlertDialog.Builder mBuilder = new AlertDialog.Builder(MainActivity.this);
View mView = getLayoutInflater().inflate(R.layout.language_dialog, null);
mBuilder.setTitle("select language");
final Spinner mSpinner = (Spinner) mView.findViewById(R.id.lang_spinner);
final ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this,
android.R.layout.simple_spinner_item, getResources().getStringArray(R.array.lang_array));
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setAdapter(adapter);
mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
SharedPreferences.Editor editor = sharedpreferences.edit();
//SELECTING LANGUAGE switch case (translate btn)-
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int position, long id) {
Object item = adapterView.getItemAtPosition(position);
if (item != null) {
switch (position) {
case 0:
item = "-";
btnTrans.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), R.string.nista, Toast.LENGTH_LONG).show();
}
});
break;
case 1:
item = "lang1";
btnTrans.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), R.string.hrvatski, Toast.LENGTH_LONG).show();
}
});
break;
case 2:
item = "lang2";
btnTrans.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), R.string.english, Toast.LENGTH_LONG).show();
}
});
break;
}
}
//on selected save
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
//nothing selected "-"
}
});

I am rep is less then 50 so I am posting link here for shared preference

Get your Lang from spinner and store value in share preference.

Dialog dismiss not working inside adapter

I have a modal(dialog) with a edit text inside and a send button, what i'm trying to do is simply send the content inside the edit text when the button is clicked, the thing is, sending the content is working, but when i call mydialog.dismiss(); it doesn't work. It is using an instance of another class to call a method retrofit, and inside the "done" and "not done" buttons i have the "enviar"(send) button which is the one i'm trying to close the modal with.
Here is the adapter code:
public TasksAdapter(#NonNull Context context, #SuppressLint("SupportAnnotationUsage") #LayoutRes ArrayList<Tasks> list){
super(context, 0, list);
sContext = context;
taskData = list;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent){
View listItem = convertView;
if(listItem == null)
listItem = LayoutInflater.from(sContext).inflate(R.layout.item_tasks, parent,false);
final Tasks presenteTask = taskData.get(position);
TextView taskTitle = (TextView) listItem.findViewById(R.id.tasksTitle);
taskTitle.setText(presenteTask.getTitle());
EditText taskColor = (EditText) listItem.findViewById(R.id.taskColor);
if(presenteTask.getHexaColor().isEmpty()){
HexaColor = "#FFFFFF";
}
else{
HexaColor = presenteTask.getHexaColor();
taskColor.setBackgroundColor(Color.parseColor(HexaColor));
}
TextView taskTime = (TextView) listItem.findViewById(R.id.taskTime);
taskTime.setText(presenteTask.getTimeStart().toString().substring(0,5));
tasksModal = new Dialog(sContext);
tasksModal.setCancelable(false);
tasksModal.setContentView(R.layout.modal_tasksdone);
tasksModal.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
final EditText comentarios = (EditText) tasksModal.findViewById(R.id.edtComentario);

Thank you very much!

Firstly you have to make your dialog un-cancelable, so that outside click doesn't dismiss it using tasksModal.setCancelable(false);
Secondly no need to repeat code to create dialog inside done/undone button click. So, remove it and move it to TasksAdapter constructor.
Thirdly You are not dismissing your dialog inside done button click. So, add this tasksModal.dismiss();
Check and try with below code:
EditText comentarios;
Calendario calendario;
public TasksAdapter(#NonNull Context context, #SuppressLint("SupportAnnotationUsage") #LayoutRes ArrayList<Tasks> list){
super(context, 0, list);
sContext = context;
taskData = list;
tasksModal = new Dialog(sContext);
tasksModal.setCancelable(false); //make it un cancelable
tasksModal.setContentView(R.layout.modal_tasksdone);
tasksModal.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
comentarios = (EditText) tasksModal.findViewById(R.id.edtComentario);
calendario = new Calendario();
}
-------------------------------------------------------------
Button done = (Button) listItem.findViewById(R.id.tasksDone);
done.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
comentarios.setText("");
yorn = true;
tarefaId = presenteTask.getTaskId();
data = presenteTask.getDataTask();
hora = String.valueOf(presenteTask.getTimeStart());
tasksModal.findViewById(R.id.btnSend).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
comentario = comentarios.getEditableText().toString();
if(!comentario.equals("")){
tasksModal.dismiss(); //dismiss here
calendario.retrofitDoneTasks(tarefaId, comentario, data, hora, yorn, tarefaRealizadaId);
}
else{
Toast.makeText(sContext,"Por favor digite um comentário.", Toast.LENGTH_SHORT).show();
}
}
});
tasksModal.show();
}
});
Button notDone = (Button) listItem.findViewById(R.id.tasksNotDone);
notDone.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
comentarios.setText("");
yorn = false;
tarefaId = presenteTask.getTaskId();
data = presenteTask.getDataTask();
hora = String.valueOf(presenteTask.getTimeStart());
tasksModal.findViewById(R.id.btnSend).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
comentario = comentarios.getEditableText().toString();
if(comentario.equals("")){
Toast.makeText(sContext,"Por favor digite um comentário.", Toast.LENGTH_SHORT).show();
}
else{
tasksModal.dismiss();
calendario.retrofitDoneTasks(tarefaId, comentario, data, hora, yorn, tarefaRealizadaId);
}

Java android open snackBar after click on marker

I want to open a snackBar after that I clicked on marker I tr do this :
gMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker) {
for(PGO pgo : pgoList.pgos){
if(pgo.getFull().equalsIgnoreCase(marker.getTitle())){
currentPGO = pgo;
view = getCurrentFocus();
mySnackbar(pgo,view);
}
}
return false;
}
});
public void mySnackbar(PGO pgo, View view) {
LinearLayout.LayoutParams objLayoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
Snackbar snackbar = Snackbar.make(view, "", Snackbar.LENGTH_INDEFINITE);
Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView();
layout.setPadding(0, 0, 0, 0);
LayoutInflater mInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View snackView = getLayoutInflater().inflate(R.layout.my_snackbar, null);
Button textViewOne = (Button) snackView.findViewById(R.id.txtOne);
TextView tvName = (TextView) snackView.findViewById(R.id.name);
tvName.setText(pgo.getFull());
textViewOne.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.i("One", "First one is clicked");
snackbar.dismiss();
}
});
Button textViewTwo = (Button) snackView.findViewById(R.id.txtTwo);
textViewTwo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.i("Two", "Second one is clicked");
}
});
layout.addView(snackView, objLayoutParams);
snackbar.show();
}
But my application is crashed and in the log I see :
java.lang.IllegalArgumentException: No suitable parent found from the
given view. Please provide a valid view.
Ok I do this and it works:
getWindow().getDecorView(),
But now when show Snackbar I want to see the whole map, this Snackbar cover my map

If you don't have a view on focus you can use the default android one as follows:
view = findViewById(android.R.id.content);

try this
Use this function to show the message.
public void showMessage(Activity context, String message) {
Snackbar snackbar = Snackbar.make(context.getWindow().getDecorView().findViewById(android.R.id.content), message, Snackbar.LENGTH_LONG);
View snackBarView = snackbar.getView();
snackBarView.setBackgroundColor(context.getResources().getColor(R.color.colorPrimary));
TextView textView = (TextView) snackBarView.findViewById(android.support.design.R.id.snackbar_text);
textView.setTextColor(context.getResources().getColor(R.color.white));
snackbar.show();
}
For your UseCase
gMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker) {
for(PGO pgo : pgoList.pgos){
if(pgo.getFull().equalsIgnoreCase(marker.getTitle())){
currentPGO = pgo;
showMessage(MainActivity.this,pgo.getFull());
}
}
return false;
}
});

I created a custom snackbar , where the views are wrapped within a CoordinatorLayout for a Fragment.
#Override
public boolean onMarkerClick(Marker marker) {
if (marker.getTag() != null) {
marker.showInfoWindow();
int tag = (int) marker.getTag();
showCustomSnackBar(marker, 10000, tag);
}
return false;
private void showCustomSnackBar(Marker marker, int duration, int tag) {
if (getActivity() != null && !(getActivity()).isFinishing()) {
CoordinatorLayout rootCoordinatorLayout = view.findViewById(R.id.parent_coordinator_layout);
Snackbar snackbar = Snackbar.make(rootCoordinatorLayout, "", duration);
Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView();
layout.setBackgroundColor(getResources().getColor(R.color.white));
LayoutInflater objLayoutInflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View snackView = objLayoutInflater.inflate(R.layout.snackbar_layout_view, null);
ImageView someImgView = snackView.findViewById(R.id.someImageView);
TextView sometxt = snackView.findViewById(R.id.snackbar_msg);
someImgView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
snackbar.dismiss();
}
});
layout.addView(snackView, 0);
snackbar.show();
}
}
}

How to pass same value to two fragment using single interface
