1- Create a new project in Android Studio called AlertDialog (alertdialog android studio). Of course, it should be noted that the name of the project is arbitrary and you can choose another name for it. The chosen name for this project in this tutorial is AlertDialog.2- After creating the project, it is better to create an Empty Activity.3- In this project, we need the appcompat-v7 library in order to be able to perform our desired operations. It is better to add it to the project as well.4- In the activity, we create an example of AlertDialog.Builder and of course we choose the desired name for it. For example, the name of choice in this project is alertBuilder.5- Then we have to do the following inside the onCreate method.

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

public class MainActivity extends AppCompatActivity {

AlertDialog.Builder alertBuilder;

@Override
protected void onCreate (Bundle savedInstanceState) {
super. onCreate (savedInstanceState);
setContentView (R. layout. activity_main);

alertBuilder = new AlertDialog.Builder (this);

}
}
In the code above, AlertDialog.Builder currently receives a parameter, which is also Context.

Note:

Be sure to select AlertDialog, which is related to the support library.6- Create a simple AlertDialog.7- Then we complete it as follows.
