How to create a new card after taking input from dialog box

Basically on clicking a button a dialog box opens from which I am capturing information. Once I click on "Done" option present in the Dialog box, I want a new card to be created comprising of that information. I have implemented recycler view for achieving the above but for some reason it is not working. Could someone tell me what's wrong?
Here's the code of my Adapter
package com.example.android.teleconsultation_doctor;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.util.ArrayList;
public class AdapterManageSlots extends RecyclerView.Adapter<AdapterManageSlots.ManageSlotsViewHolder> {
private ArrayList<CardViewManageSlots> mManageSlots;
public static class ManageSlotsViewHolder extends RecyclerView.ViewHolder{
public TextView mSlots, mTiming;
public ManageSlotsViewHolder(#NonNull View itemView) {
super(itemView);
mTiming = itemView.findViewById(R.id.textViewTimingValue);
mSlots = itemView.findViewById(R.id.textViewSlotValue);
}
}
public AdapterManageSlots(ArrayList<CardViewManageSlots> manageSlots){
mManageSlots = manageSlots;
}
#NonNull
#Override
public ManageSlotsViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.cardview_manage_slots, viewGroup, false);
ManageSlotsViewHolder evh = new ManageSlotsViewHolder(v);
return evh;
}
#Override
public void onBindViewHolder(#NonNull ManageSlotsViewHolder manageSlotsViewHolder, int i) {
CardViewManageSlots currentItem = mManageSlots.get(i);
manageSlotsViewHolder.mSlots.setText(currentItem.getSlot());
manageSlotsViewHolder.mTiming.setText(currentItem.getTiming());
}
#Override
public int getItemCount() {
return mManageSlots.size();
}
}

If I understand it correctly, you want something like this:
mBuilder.setPositiveButton("Done", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
spinnerSlotValue = mSpinnerSlots.getSelectedItem().toString();
spinnerStartTimeValue = mSpinnerStartTime.getSelectedItem().toString();
spinnerEndTimeValue = mSpinnerEndTime.getSelectedItem().toString();
String finalTime = spinnerStartTimeValue + "-" + spinnerEndTimeValue;
slotDetails.add(new CardViewManageSlots(spinnerSlotValue,finalTime));
mAdapter.notifyDataSetChanged();
dialogInterface.dismiss();
}
});

How to access another class function from another class (java)

I'm new to java and I'm currently testing it in android studio.
I'm trying to access function showMessage() in TEST class from TEST2 class.
There is no problem if showMessage() function is called within the same class but the code stopped if I tried to access it from another class.
Maybe there is something wrong with my logic or syntax, but I'm not entirely sure which one is it. I already tried to search for some solution but there is no answer that I can find to help with my situation.
Here is my TEST.java code
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
public class TEST extends AppCompatActivity {
public TEST2 ab;
Button button;
private final String text ="Testing test test test testing test";
public void showMessage(String message) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(message)
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
}
})
.setCancelable(false) // cancel with button only
.show();
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
button = (Button) findViewById(R.id.buttontest);
ab = new TEST2(this);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
showMessage(text);
}
});
}
}
class TEST2 extends View{
public TEST t = new TEST();
public TEST2(Context context) {
super(context);
//there is error if I tried this 2 line code
//onTest();
//t.showMessage("TESTING FROM TEST2 CLASS");
}
public void onTest(){
t.showMessage("TESTING FROM TEST2 CLASS");
}
}
and this is my activity_test.xml layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="#+id/buttontest"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</RelativeLayout>

You can do this by passing parameter context
public void showMessage(String message, Context context) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage(message)
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
}
})
.setCancelable(false) // cancel with button only
.show();
}

Alert Dialog is a UI element it will not run from another class if activity is changed. if activity is not change try this...
public void showMessage(final String message,final Context mContext) {
runOnUiThread(new Runnable() {
#Override
public void run() {
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setMessage(message)
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
}
})
.setCancelable(false) // cancel with button only
.show();
}
});
}

public void onTest(){
if (getContext() instanceof Test)
((Test)getContext()).showMessage("TESTING FROM TEST2 CLASS");
}

Just pass the Context of your TEST2 class.
public void showMessage(Context context, String message) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
.............
......................
}
TEST2:
public TEST2(Context context) {
super(context);
t.showMessage(context, "TESTING FROM TEST2 CLASS");
}

Want to Ask users to confirm his info is correct before startActivity, android

Hello I m newbie in Android development.
So i practiced with one sample which is sending ussd code to operator such as recharging bill. I am okay with that.
But my main problem is to show dialog box when clicking button1 after filling PIN code to examine the user correct or not.
I don't know how to add and what to add.
My codes are -
for MainActivity.java
package com.messagealert;
import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener(){
public void onClick (View v){
EditText editText1 =(EditText) findViewById(R.id.editText1);
String pin = editText1.getText().toString();
String encodedHash = Uri.encode("#");
String ussd = "*" + "124" + pin + encodedHash;
Intent button1 = new Intent(android.content.Intent.ACTION_CALL, Uri.parse("tel:" + ussd));
startActivity(button1);
}
});
}
[MENTION=439709]override[/MENTION]
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

Please guide what i need to put & where exactly to show a dialog box "Is that your PIN code - xxxxxx" & Yes or No
Sorry for my bad English.
With Best Regards,

Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener(){
public void onClick (View v){
EditText editText1 =(EditText) findViewById(R.id.editText1);
String pin = editText1.getText().toString();
AlertDialog.Builder dlgAlert = new AlertDialog.Builder(this);
dlgAlert.setMessage("PIN VERIFICATION");
dlgAlert.setTitle("Is that your PIN code -"+pin );
dlgAlert.setPositiveButton("OK", null);
dlgAlert.setCancelable(true);
dlgAlert.create().show();
dlgAlert.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
String encodedHash = Uri.encode("#");
String ussd = "*" + "124" + pin + encodedHash;
Intent button1 = new Intent(android.content.Intent.ACTION_CALL, Uri.parse("tel:" + ussd));
startActivity(button1);
}
});
dlgAlert.setNegativeButton("NO",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
editText1 .setText(" ");
}
});

For this you have to add alert box Just like the below code
new AlertDialog.Builder(this)
.setTitle("Delete entry")
.setMessage("Are you sure you want to delete this entry?")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
or try this
AlertDialog.Builder builder1 = new AlertDialog.Builder(context);
builder1.setMessage("Write your message here.");
builder1.setCancelable(true);
builder1.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
builder1.setNegativeButton("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert11 = builder1.create();
alert11.show();

Just add dialog in your button click only
EditText editText1 =(EditText) findViewById(R.id.editText1);
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener(){
public void onClick (View v){
//call dialog here and on dialog ok press start your activity
String pin = editText1.getText().toString();
String encodedHash = Uri.encode("#");
String ussd = "*" + "124" + pin + encodedHash;
Intent button1 = new Intent(android.content.Intent.ACTION_CALL, Uri.parse("tel:" + ussd));
startActivity(button1);
}
});

Use code below, this will help you:
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener(){
public void onClick (View v){
dialog();
}
});
public void dialog()
{
AlertDialog.Builder dialog = new Builder(con);
dialog.setTitle("Message:");
dialog.setMessage("Is that your PIN code - xxxxxx");
dialog.setNegativeButton("NO", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
dialog.setPositiveButton("YES", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
EditText editText1 =(EditText) findViewById(R.id.editText1);
String pin = editText1.getText().toString();
String encodedHash = Uri.encode("#");
String ussd = "*" + "124" + pin + encodedHash;
Intent button1 = new Intent(android.content.Intent.ACTION_CALL, Uri.parse("tel:" + ussd));
startActivity(button1);
dialog.dismiss();
}
});
dialog.show();
}
use variable global if needed.

use an alertDialog for that inside you button onClick
AlertDialog.Builder dialog = new Builder(con);
dialog.setTitle("Confirm PIN");
dialog.setMessage("You have entered pincode as"+pin+"\n Please Confirm to Continue");
dialog.setNegativeButton("Edit Pin", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
dialog.setPositiveButton("Confirm", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
EditText editText1 =(EditText) findViewById(R.id.editText1);
String pin = editText1.getText().toString();
String encodedHash = Uri.encode("#");
String ussd = "*" + "124" + pin + encodedHash;
Intent button1 = new Intent(android.content.Intent.ACTION_CALL, Uri.parse("tel:" + ussd));
startActivity(button1);
dialog.dismiss();
}
});
dialog.show();

Firstly, I am very thank you for your answers.
Sorry i can't vote up your answers because i haven't enough reputations.
By adapting MSS's answers i changed a bit at MainActivity.java
package com.messagealert;
import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity {
final Context context = this;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener(){
public void onClick (View v){
EditText editText1 =(EditText) findViewById(R.id.editText1);
String pin = editText1.getText().toString();
AlertDialog.Builder dlgAlert = new AlertDialog.Builder(context);
dlgAlert.setTitle("PIN VERIFICATION");
dlgAlert.setMessage("Is that your PIN code -" + pin );
dlgAlert.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
String encodedHash = Uri.encode("#");
EditText editText1 =(EditText) findViewById(R.id.editText1);
String pin = editText1.getText().toString();
String ussd = "*" + "124" + pin + encodedHash;
Intent button1 = new Intent(android.content.Intent.ACTION_CALL, Uri.parse("tel:" + ussd));
startActivity(button1);
}
});
dlgAlert.setNegativeButton("NO",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
EditText editText1 =(EditText) findViewById(R.id.editText1);
editText1 .setText(" ");
}
});
dlgAlert.setCancelable(true);
dlgAlert.create().show();
};
});
}}
You guys did a great help on me!

How can I target an EditText on a DialogFragment

I created a DialogFragment that looks like this:
package com.name.test;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.content.DialogInterface;
import android.os.Bundle;
import android.text.Editable;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
import com.name.test.MainActivity.DialogType;
public class AlertDialogFragment extends DialogFragment {
public static DialogType type;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
View v = getActivity().getLayoutInflater().inflate(R.layout.search_fragment, null);
final EditText searchField = (EditText)v.findViewById(R.id.searchEditTxt);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
switch(type) {
case SEARCH:
builder.setView(inflater.inflate(R.layout.search_fragment, null))
.setTitle("Search Dialog")
.setPositiveButton("Search", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// logic for the search button
// Toast.makeText(getActivity().getBaseContext(), "Search Dialog", Toast.LENGTH_SHORT).show();
String tempString = searchField.getText().toString();
System.out.println(tempString);
}
})
//.setView(searchField)
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// logic for the cancel button
AlertDialogFragment.this.getDialog().cancel();
}
});
break;
case PREFERENCES:
builder.setView(inflater.inflate(R.layout.preferences_fragment, null))
.setTitle("Preferences")
.setPositiveButton("Save", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// logic for the search button
Toast.makeText(getActivity().getBaseContext(), "Preferences", Toast.LENGTH_SHORT).show();
}
})
//.setView(searchField)
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// logic for the cancel button
AlertDialogFragment.this.getDialog().cancel();
}
});
break;
default:
break;
}
return builder.create();
}
public static AlertDialogFragment newInstance(DialogType dialogType) {
type = dialogType;
return new AlertDialogFragment();
}
}
In the XML file for this fragment I have this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="search_fragment"
android:orientation="vertical" >
<EditText
android:id="#+id/searchEditTxt"
android:hint="#string/search_menu_hint"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
I'm trying to target that EditText in the DialogFragment so when the user types something and clicks on Save or OK I can store its value. I can't seem to be able to target the EditText properly. My System.out.println(tempString); is empty. What am I doing wrong? Thanks much.

try to change
builder.setView(inflater.inflate(R.layout.search_fragment, null));
to
builder.setView(v);
You just need to set your inflated view to your builder.
