Android Dialog Box Example...
Open xml file and below code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent">

    <Button

        android:id="@+id/button1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentLeft="true"

        android:layout_alignParentTop="true"

        android:layout_marginLeft="24dp"

        android:layout_marginTop="17dp"

        android:text="CLOSE"

        android:onClick="close" />

</RelativeLayout>


Now open java file and paste below code

package selecom.alert;

importandroid.os.Bundle;

importandroid.app.Activity;

importandroid.app.AlertDialog;

importandroid.app.AlertDialog.Builder;

importandroid.app.Dialog;

importandroid.content.DialogInterface;

importandroid.view.View;

importandroid.widget.Toast;

public class MainActivity extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

     

    }

    public void close(View v)

    {

      onCreateDialog(10);

    }

protected Dialog onCreateDialog(int id)

{

      switch(id)

      {

      case 10:

            Builder builder=newAlertDialog.Builder(this);

            builder.setMessage("Activity will close!!!");

            builder.setTitle("Warning...");

            builder.setIcon(R.drawable.warning_image);

//button 

            builder.setNegativeButton("No", new DialogInterface.OnClickListener() {

                 

                  @Override

                  public voidonClick(DialogInterface dialog, int which)

                  {

                        Toast.makeText(getApplicationContext(), "Nothing happened", Toast.LENGTH_LONG).show();

                       

                  }

            });

//button

      builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {

                 

                  @Override

                  public voidonClick(DialogInterface dialog, int which)

                  {

                        finish();

                       

                  }

            });

//button

      builder.setNeutralButton("Thinking", newDialogInterface.OnClickListener() {

           

            @Override

            public voidonClick(DialogInterface dialog, int which)

            {

                  Toast.makeText(getApplicationContext(), "i have to think", Toast.LENGTH_LONG).show();

                 

            }

      });

           

      AlertDialog dialog=builder.create();

      dialog.show();

           

      }

      return super.onCreateDialog(id);

     

}

  

} 

We can use maximum three buttons in dialog box by default and builder is used to create dialog box. Sequence of the buttons to appear on box: positive, neutral than negative.
