Multiple Intents passing listView info from one activity to another

I'm trying to pass information from my second activity to my first activity. In my second Activity contains a list view of images of provinces in Canada. Each item in the list contains 3 properties (Province Name, Capital of the Province, Image id for the actual flag of the province). When the user selects an item from the listView it should direct them to the first Activity and pass the intent information from the second Activity to the first Activity. The information that will be passed are the name of the province and the capital of the province. I feel like I'm doing it correctly and my app currently has no issue in terms of bugs or crashes but I can't seem to figure out why the information is not being passed from activity 2 to activity 1. It just passes nothing. Thanks to those all in advance that help me out!

You forget to start the intent
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
Province province = (Province) listView.getItemAtPosition(position);
Intent intent = new Intent(this.Second_Activity.class, MainActivity);
intent.putExtra("name", province.getName());
intent.putExtra("capital", province.getCapital());
startActivity(intent);
finish();
}
});
receive the intent
public void display(){
Bundle extras = intent.getExtras();
if(extras != null){
String provinceString = extras.getString("name");
provinceTxt.setText(provinceString);
String capitalString = extras.getString("capital");
capitalTxt.setText(capitalString);
}
}
for more details refer this

you can use Activity.startActivityForResult(Intent intent, int requestCode)to start Second Activity and use Activity.onActivityResult(int requestCode, int resultCode, Intent data) to receive data that from Second Activityin MainActivity

RecycleView doesen't show any value

My RecyclerView doesn't show any value in alert dialog. I am confused and don't know where should I looking for a problem in my code. I hope some of you guys met with same issue.
This is activity where I am calling my RecycleView andl AlertDialog.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pondeljak = (Button) findViewById(R.id.buttonPonedeljak);
utorak = (Button) findViewById(R.id.buttonUtorak);
sreda = (Button) findViewById(R.id.buttonSreda);
cetvrtak = (Button) findViewById(R.id.buttonCetvrtak);
petak = (Button) findViewById(R.id.buttonPetak);
db = new DataDays(this);
View view = getLayoutInflater().inflate(R.layout.casovi,null);
alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setView(view);
alertDialog = alertDialogBuilder.create();
recyclerView = (RecyclerView) view.findViewById(R.id.recycleCasoviID);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
casoviList = new ArrayList<>();
casoviItems = new ArrayList<>();
// for (Casovi c: casoviList){
Casovi casovi = new Casovi();
//casovi.setId(0);
casovi.setDan("asas");
casovi.setRedniBrCasa("ssss");
casovi.setNzaivCasa("ssddff");
casoviItems.add(casovi);
recycleViewAdapter = new RecycleViewAdapter(this, casoviItems);
recyclerView.setAdapter(recycleViewAdapter);
recycleViewAdapter.notifyDataSetChanged();
pondeljak.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (db.casoviCountPondeljak() == 0){
Intent intent = new Intent(MainActivity.this, Unos_casova.class);
intent.putExtra("Dan", "Pondeljak");
startActivity(intent);
}else {
alertDialog.show();
}
This is RecycleView class. I am not sure, maybe here is some problem?
public class RecycleViewAdapter extends RecyclerView.Adapter<RecycleViewAdapter.ViewHolder> {
private Context context;
private List<Casovi> casoviItems;
public RecycleViewAdapter(Context context, List<Casovi> casoviItems) {
this.context = context;
this.casoviItems = casoviItems;
}
#Override
public RecycleViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.prikaz_casova, parent,false);
return new ViewHolder(view, context);
}
#Override
public void onBindViewHolder( RecycleViewAdapter.ViewHolder holder, int position) {
Casovi casovi = new Casovi();
holder.redniBrCasPrikaz.setText(casovi.getRedniBrCasa());
holder.nazivCasPrikaz.setText(casovi.getRedniBrCasa());
}
#Override
public int getItemCount() {
return casoviItems.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView redniBrCasPrikaz;
public TextView nazivCasPrikaz;
public Button delteBtn;
public Button editBtn;
public CardView cardView;
public ViewHolder(View view, Context ctx) {
super(view);
context = ctx;
redniBrCasPrikaz = (TextView) view.findViewById(R.id.rednibrojCasaID);
nazivCasPrikaz = (TextView) view.findViewById(R.id.nazivcasaID);
delteBtn = (Button) view.findViewById(R.id.obrisiCasBtnID);

Here the error you made, in your RecyclerView Adapter class.
#Override
public void onBindViewHolder( RecycleViewAdapter.ViewHolder holder, int position) {
Casovi casovi = new Casovi();
It should be
Casovi casovi = casoviItems.get(position);
holder.redniBrCasPrikaz.setText(casovi.getRedniBrCasa());
holder.nazivCasPrikaz.setText(casovi.getRedniBrCasa());
}
You are all done

Add dynamically components to a Custom Dialog in Android

I'd need your help to do something in Android, in the following the use case.
I have created a custom dialog in Android, whose layout is:
dialog_threshold.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="20dp">
<ImageView
android:src="#drawable/ic_media_route_on_03_dark"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="center"
android:background="#FFFFBB33"
android:contentDescription="#string/set_target" />
<Spinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/spinner_threshold" />
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/layout_threshold">
<TextView
android:text=""
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/targetSelected"
android:layout_weight="1" />
<Spinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/threshold_operator_spinner"
android:layout_weight="1" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="textPersonName"
android:text=""
android:ems="10"
android:id="#+id/threshold_val"
android:layout_weight="1" />
</LinearLayout>
</LinearLayout>
And in the Activity, when I click on a specific button, I have something like this, to create the custom dialog:
setThreshold_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
AlertDialog.Builder mBuilder = new AlertDialog.Builder(DiseaseActivity.this);
//Inflate the custom layout
View mView = getLayoutInflater().inflate(R.layout.dialog_threshold, null);
//Set title for dialog
mBuilder.setTitle("Set thresholds for your target");
//Define the spinner inside your custom layout
final Spinner mSpinner = (Spinner) mView.findViewById(R.id.spinner_threshold); //because it doesn't exist in the main layout, but only in the custom layout
//Define the ArrayAdapter
ArrayAdapter<String> adapter = new ArrayAdapter<String>(DiseaseActivity.this,
android.R.layout.simple_spinner_item,
getResources().getStringArray(R.array.threshold_choices));
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setAdapter(adapter);
if (!mSpinner.getSelectedItem().toString().equalsIgnoreCase("Choose a threshold option")) {
String ThresholdSelection = mSpinner.getSelectedItem().toString();
}
mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if ((dialog2 != null) && dialog2.isShowing() && !mSpinner.getSelectedItem().toString().equalsIgnoreCase("Choose a threshold option")) {
dialog2.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(true);
} else {
dialog2.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false);
}
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
//Set the positive and negative button for the custom dialog
mBuilder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
disease.setThreshold(mSpinner.getSelectedItem().toString());
if (!mSpinner.getSelectedItem().toString().equalsIgnoreCase("Choose a threshold option")) {
Toast.makeText(DiseaseActivity.this,
mSpinner.getSelectedItem().toString(),
Toast.LENGTH_SHORT)
.show();
setInterval_button.setEnabled(true);
}
}
});
mBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
});
mBuilder.setView(mView);
dialog2 = mBuilder.create();
dialog2.show();
dialog2.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false);
}
});
What I want to do now is to add dynamically other components (like EditText or TextView) to the above Dialog before is it shown.
How can I do it?
Thanks in advance!

just create your custom view >> find the parent(in which viewgroup you want to add) >>> and add it. eg:-
mView.addView(new TextView(ActivityContext),LayoutParamss);
mBuilder.setView(mView);

Buttons in Custom Dialog won't respond

I'm trying to create a custom dialog for the settings of my application, the problem is, that the custom buttons, EditText & the spinner don't respond to user activity. I hope someone can help.
Here is my Code:
public class SettingsDialog extends DialogFragment {
private EditText editText;
private Spinner ipSpinner;
private MainActivity mainActivity;
private Settings settings;
private int selectedIP;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
final View dialogView = inflater.inflate(R.layout.dialog_settings, null);
mainActivity = (MainActivity) getActivity();
settings = mainActivity.getSettings();
selectedIP = settings.getSelectedIP();
editText = (EditText) dialogView.findViewById(R.id.edit_text_ip);
ipSpinner = (Spinner) dialogView.findViewById(R.id.spinner_ip);
ImageButton imageButton = (ImageButton) dialogView.findViewById(R.id.image_button_save_ip);
imageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String IP = editText.getText().toString();
settings.setIP(selectedIP, IP);
settings.settingsSave();
mainActivity.showToast("IP at " + Integer.toString(selectedIP) + " with value" + IP);
}
});
ipSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
selectedIP = position;
editText.setText(settings.getIP(selectedIP));
mainActivity.showToast(Integer.toString(position));
settings.settingsSave();
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
return;
}
});
builder.setView(inflater.inflate(R.layout.dialog_settings, null))
.setPositiveButton("Save", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
String IP = editText.getText().toString();
settings.setIP(selectedIP, IP);
settings.settingsSave();
mainActivity.showToast("IP at " + Integer.toString(selectedIP) + " with value" + IP);
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
SettingsDialog.this.getDialog().cancel();
}

Thanks in advice

You are inflating dialogView and then you set listeners for the views that are in dialogView, however when you set the view for dialog builder, you inflate the new view.
This is wrong.
builder.setView(inflater.inflate(R.layout.dialog_settings, null))
This is correct
builder.setView(dialogView)

How to set Title,Icon for custom dialog in android

I've a class which extends Dialog in android.It shows custom dialog well.But i couldn't set icon & title for that dialog.How could i do that?
My code:
public class helpDialog extends Dialog implements OnClickListener {
Button okButton;
String Description;
TextView text;
public helpDialog(Context context, String desc) {
super(context);
Description=desc;
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
/** Design the dialog in main.xml file */
setContentView(R.layout.custom);
text=(TextView)findViewById(R.id.text);
text.setText(Description);
okButton = (Button) findViewById(R.id.submit);
okButton.setOnClickListener(this);
}
#Override
public void onClick(View v) {
/** When OK Button is clicked, dismiss the dialog */
if (v == okButton)
dismiss();
}
}
My custom.xml:
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:textColor="#000000"
android:gravity="center"
android:text="Help alert for iDispatch"
android:textSize="18dp" />
<Button
android:id="#+id/submit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="OK"
android:textColor="#FFFFFF" />

USE THIS ONE
private AlertDialog AskOption()
{
AlertDialog myQuittingDialogBox =new AlertDialog.Builder(this)
//set message, title, and icon
.setTitle("Confirm Delete")
.setMessage("Do you want to Delete Employee "+listview_array[1]+" ?")
.setIcon(R.drawable.dialog_warning)
.setPositiveButton(resource.getString(R.string.yes), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton)
{
if(dh.selectEmployeeTypeById(EmpId).size()>0)
{
//CODE
}
dialog.dismiss();
}
})
.setNegativeButton(resource.getString(R.string.no), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.create();
return myQuittingDialogBox;
}
