package com.webabcd.androiddemo.view.custom;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;

import com.webabcd.androiddemo.R;

public class CustomView1Demo extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_view_custom_customview1demo);
    }
}

/layout/activity_view_custom_customview1demo.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
