Toast the result of dialog in Android

In this article, we are going to set two different options in a dialog box and toast the closable option as result.

​In the example below, we are going to use the AlertDialog.Builder class to build an alert box. This AlertBox.Builder will ask for a question and provide two buttons for yes and no.

To implement this in your program you will need to import the ‘android.support.v7.app.AlertDialog’ in your java file. Then create a layout file with a single button in the center with any text for the button.

<Button
	android:layout_width="wrap_content"
	android:layout_height="wrap_content"
	android:text="Click Here.."
	android:onClick="open"
	android:layout_marginLeft="115dp"
	android:layout_marginTop="150dp" />

As you can see the <button /> has a android:onClick attribute which is referring to open, now open is a function which is initiating the function for the process in JAVA file. It is easy and simple to create an AlertDialoge.Builer in JAVA file.

 AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);

The above line will make a Dialog and initiate it on the screen, when user clicks on any button of the dialog according to the choice we will make a Toast. That is:

Toast.makeText(MainActivity.this,"Answer is YES",Toast.LENGTH_LONG).show();

Now you are ready to use it in your project.

Java file:

package com.example.hp.myapplication;

import android.content.DialogInterface;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void open(View view){
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
        alertDialogBuilder.setMessage("Is includehelp helpful");
                alertDialogBuilder.setPositiveButton("yes",
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface arg0, int arg1) {
                                Toast.makeText(MainActivity.this,"Answer is YES",Toast.LENGTH_LONG).show();
                            }
                        });

        alertDialogBuilder.setNegativeButton("No",new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.this,"Answer is NO",Toast.LENGTH_LONG).show();
                finish();
            }
        });

        AlertDialog alertDialog = alertDialogBuilder.create();
        alertDialog.show();
    }

}
