    3. import android.support.v7.app.AppCompatActivity;
    4. import android.os.Bundle;
    5. public class MainActivity extends AppCompatActivity {
    6. @Override
    7. protected void onCreate(Bundle savedInstanceState)
    8. {
    9. super.onCreate(savedInstanceState);
    10. setContentView(R.layout.activity_main);
    11. }
    12. // Declare the onBackPressed method
    13. // when the back button is pressed
    14. // this method will call
    15. @Override
    16. public void onBackPressed()
    17. {
    18. // Create the object of
    19. // AlertDialog Builder class
    20. AlertDialog.Builder builder
    21. = new AlertDialog
    22. .Builder(MainActivity.this);
    23. // Set the message show for the Alert time
    24. builder.setMessage("Do you want to exit ?");
    25. // Set Alert Title
    26. builder.setTitle("Alert !");
    27. // Set Cancelable false
    28. // for when the user clicks on the outside
    29. // the Dialog Box then it will remain show
    30. builder.setCancelable(false);
    31. // Set the positive button with yes name
    32. // OnClickListener method is use of
    33. // DialogInterface interface.
    34. builder
    35. .setPositiveButton(
    36. "Yes",
    37. new DialogInterface
    38. .OnClickListener() {
    39. @Override
    40. public void onClick(DialogInterface dialog,
    41. int which)
    42. {
    43. // When the user click yes button
    44. // then app will close
    45. finish();
    46. }
    47. });
    48. // Set the Negative button with No name
    49. // OnClickListener method is use
    50. // of DialogInterface interface.
    51. builder
    52. .setNegativeButton(
    53. "No",
    54. new DialogInterface
    55. .OnClickListener() {
    56. @Override
    57. public void onClick(DialogInterface dialog,
    58. int which)
    59. {
    60. // If user click no
    61. // then dialog box is canceled.
    62. dialog.cancel();
    63. }
    64. });
    65. // Create the Alert dialog
    66. AlertDialog alertDialog = builder.create();
    67. // Show the Alert Dialog box
    68. alertDialog.show();
    69. }
    70. }

    the above program will generte the an alert when we try to exit the app
