/**

 * 通过一个自定义 View 来演示 measure, layout, draw
 */

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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <!--

    -->

    <com.webabcd.androiddemo.view.custom.CustomView1
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:titleBackgroundColor="@color/red"
        app:titleColor="@color/white"
        app:titleSize="24dp"
        app:titleText="text" />

    <com.webabcd.androiddemo.view.custom.CustomView1
