How to display a Yes/No dialog box on Android?

Question

Yes, I know there's AlertDialog.Builder, but I'm shocked to know how difficult (well, at least not programmer-friendly) to display a dialog in Android.

I used to be a .NET developer, and I'm wondering is there any Android-equivalent of the following?

if (MessageBox.Show("Sure?", "", MessageBoxButtons.YesNo) == DialogResult.Yes){
    // Do something...
}

Answer 1

Asking a Person whether he wants to call or not Dialog..

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
import android.widget.Toast;

public class Firstclass extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.first);

        ImageView imageViewCall = (ImageView) findViewById(R.id.ring_mig);

        imageViewCall.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) 
            {
                try
                {
                    showDialog("0728570527");
                }
                catch (Exception e) 
                {
                    e.printStackTrace();
                }

            }

        });

    }

    public void showDialog(final String phone) throws Exception
    {
        AlertDialog.Builder builder = new AlertDialog.Builder(Firstclass.this);

        builder.setMessage("Ring: " + phone);       

        builder.setPositiveButton("Ring", new DialogInterface.OnClickListener() 
        {
            @Override
            public void onClick(DialogInterface dialog, int which) 
            {
                Intent callIntent = new Intent(Intent.ACTION_DIAL);// (Intent.ACTION_CALL);

                callIntent.setData(Uri.parse("tel:" + phone));

                startActivity(callIntent);

                dialog.dismiss();
            }
        });

        builder.setNegativeButton("Abort", new DialogInterface.OnClickListener() 
        {   
            @Override
            public void onClick(DialogInterface dialog, int which) 
            {
                dialog.dismiss();
            }
        });

        builder.show();
    }

}

Steve H's answer is spot on, but here's a bit more information: the reason that dialogs work the way they do is because dialogs in Android are asynchronous (execution does not stop when the dialog is displayed). Because of this, you have to use a callback to handle the user's selection.

Check out this question for a longer discussion between the differences in Android and .NET (as it relates to dialogs): Dialogs / AlertDialogs: How to "block execution" while dialog is up (.NET-style)

Answer 3

1.Create AlertDialog set message,title and Positive,Negative Button:

final AlertDialog alertDialog = new AlertDialog.Builder(this)
                        .setCancelable(false)
                        .setTitle("Confirmation")
                        .setMessage("Do you want to remove this Picture?")
                        .setPositiveButton("Yes",null)
                        .setNegativeButton("No",null)
                        .create();

2.Now find both buttons on DialogInterface Click then setOnClickListener():

alertDialog.setOnShowListener(new DialogInterface.OnShowListener() {
            @Override
            public void onShow(DialogInterface dialogInterface) {
                Button yesButton = (alertDialog).getButton(android.app.AlertDialog.BUTTON_POSITIVE);
                Button noButton = (alertDialog).getButton(android.app.AlertDialog.BUTTON_NEGATIVE);
                yesButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        //Now Background Class To Update Operator State
                        alertDialog.dismiss();
                        Toast.makeText(GroundEditActivity.this, "Click on Yes", Toast.LENGTH_SHORT).show();
                        //Do Something here 
                    }
                });

                noButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        alertDialog.dismiss();
                        Toast.makeText(GroundEditActivity.this, "Click on No", Toast.LENGTH_SHORT).show();
                        //Do Some Thing Here 
                    }
                });
            }
        });

3.To Show Alertdialog:

alertDialog.show();

Note: Don't forget Final Keyword with AlertDialog.

Answer 4

AlertDialog.Builder altBx = new AlertDialog.Builder(this);
    altBx.setTitle("My dialog box");
    altBx.setMessage("Welcome, Please Enter your name");
    altBx.setIcon(R.drawable.logo);

    altBx.setPositiveButton("Ok", new DialogInterface.OnClickListener()
    {
      public void onClick(DialogInterface dialog, int which)
      {
          if(edt.getText().toString().length()!=0)
          {
              // Show any message
          }
          else 
          {

          }
      }
    });
    altBx.setNeutralButton("Cancel", new DialogInterface.OnClickListener()
    {
      public void onClick(DialogInterface dialog, int which)
      {
          //show any message
      }

    });
  altBx.show();  

Answer 5

In Kotlin:

AlertDialog.Builder(this)
    .setTitle(R.string.question_title)
    .setMessage(R.string.question_message)
    .setPositiveButton(android.R.string.yes) { _, _ -> yesClicked() }
    .setNegativeButton(android.R.string.no) { _, _ -> noClicked() }
    .show()

Thanks. I use the API Level 2 (Android 1.1) and instead of BUTTON_POSITIVE and BUTTON_NEGATIVE i have to use BUTTON1 and BUTTON2.
