Step 6 − Add the following code to src/MainActivity.java
package com.app.sample; import androidx.appcompat.app.AlertDialog; import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); findViewById(R.id.buttonShowDialog).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { showCustomDialog(); } }); } private void showCustomDialog() { ViewGroup viewGroup = findViewById(android.R.id.content); View dialogView = LayoutInflater.from(this).inflate(R.layout.my_dialog, viewGroup, false); AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setView(dialogView); AlertDialog alertDialog = builder.create(); alertDialog.show(); } }
Step 7 − Add the following code to Manifests/AndroidManifest.xml
