Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/parent"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity"
   android:gravity="center"
   android:orientation="vertical">
   <Button
      android:id="@+id/customDialog"
      android:text="Custom Dialog"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" />
</LinearLayout>

In the above code, we have taken button. When user click on button, it will show dialog.

Step 3 − Add the following code to src/MainActivity.java

package com.example.andy.myapplication;
import android.content.DialogInterface;
import android.os.Build;
import android.os.Bundle;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
   @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      findViewById(R.id.customDialog).setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            final AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this, R.style.CustomAlertDialog);
            builder.setTitle("Alert Dialog");
            builder.setMessage("Lorem Ipsum is simply dummy text of the printing and typesetting industry.
               Lorem Ipsum has been the industry's standard dummy text ever since the 1500s");
            builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
               @Override
               public void onClick(DialogInterface dialog, int which) {
                  Toast.makeText(MainActivity.this, "You have clicked yes", Toast.LENGTH_LONG).show();
               }
            });
            builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
               @Override
               public void onClick(DialogInterface dialog, int which) {
                  Toast.makeText(MainActivity.this, "You have clicked No", Toast.LENGTH_LONG).show();
               }
            });
            builder.setNeutralButton("Cancel", new DialogInterface.OnClickListener() {
               @Override
               public void onClick(DialogInterface dialog, int which) {
                  Toast.makeText(MainActivity.this, "You have clicked Neutral", Toast.LENGTH_LONG).show();
               }
            });
            final AlertDialog alertDialog = builder.create();
            alertDialog.show();
         }
      });
   }
