开发开始

很早之前参与编写了一篇语录，大概有3W字，正好学习了android开发的一些相关知识，能否通过这个机会开发出一个app展示语录，就类似阅读器这种的。

尝试写第一个页面

刘

这一部分是关于将的介绍，那么肯定是从宇轩开始。

            \n\t\t\t\t英文名LIGHT SHEEN(简称LS),来自一班。是戏曲里的彩旦,因为彩旦专演丑角。具有纯正的宇轩血统,是唯一的光系宇轩。长相奇丑无比,也不知道是什么原因。具有满脸痘和超亮大奔头。长相很奇特而且较黑,正面看根本看不见头发,一低头就可以看见她的发际线离眉毛很远,于是奔头就很大,而且侧面的头发也濒临消失,但她在合影的时候永远站在第一个,真够惊悚的。
            \n\t\t\t\t宇轩奔遇阳光可反射光芒,储存光芒,放光芒。但长相都是次要的,最关键她道德品质极其败坏,允许她说别人但不允许别人说她,不愧是相由心生。坐在别人椅子上,嫌人家书包硌得慌,就直接把人家的书包扔在地上。对鸡毛蒜皮不值得一提的小事斤斤计较个没完没了。初三上半学期的最后,老师发糖,宇呕就用臭爪子把糖抓来抓去,乱挑,真是恶心到家了。
            \n\t\t\t\t为了寻求保护和宠爱,经常拍老师马屁,当老师一面,背着老师一面。脾气暴,嗓门大,极其张扬。令人胆怯,闻其声而知其名,闻风丧胆,一眼都不能看,因为看完就会失明。挑拨离间女生间关系,还掐女生脖子,使得全班人都排斥她。贪污退回的饭费,一向一毛不拔的宇来还拿赃款请女生吃东西。\n\t\t\t\t著有名言:(宇轩怒之千古绝唱)“给我道歉。”

调整了布局以及按钮的逻辑，同理制作出张，伪，中将和小将的信息。

关于其中的信息传递逻辑实现

本来使用的是相应的每一个界面都有一个Setting按钮，对于文字颜色进行调整，而后发现比如A界面更改了信息，B界面还要经历一次修改过程，每一步都要用Bundle来完成么？显然繁琐，于是找到了sharedPreferences的方式，类似共享内存，不过建议是存储一些简单的信息。

完成夫的相应逻辑

思考能否进一步精简

因为之前每一次都是要定义类似的控件，能否创建一个类，使得其new一个实例，再往里赋值就可以了。在实现的过程中，发现可以直接采用继承的方式，甚至不需要使用new一个实例。

不过在获取对象时遇到了空指针的问题如下

sharedPreferences null pointer?

我最初是在那个基类中获取的所有的Button，View等控件，会出现android：Initializing SharedPreferences提供：尝试在空对象引用上调用虚拟方法的问题。而后下午更改至OnCreate方法中竟然就不再报错，那么暂时不想深究，继续其他的开发。

当解决这个问题后发现采用相应的类进行开发，编写速度会有很大的提升，因为此时对于一个新的类，仅仅在获取控件的时候采用不同的id即可，而无需创建新的不同命名的控件。

于是创建了相应夫的xml与java文件进行交互。

模板类

import android.content.SharedPreferences;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.TextView;

import androidx.appcompat.app.AppCompatActivity;

public class FuView extends AppCompatActivity {
    //布局文件
    private android.view.View fuActivity;
    //文字大小
    private int textSize;
    //设置请求
    public static final int REQUEST_CODE = 1;
    //返回按钮
    private Button fuButton;
    //介绍文字
    private TextView fuText;
    //设置按钮
    private ImageButton fuSettingButton;

    public SharedPreferences sharedPreferences;
    public SharedPreferences.Editor editor;

    public TextView getFuText() {
        return fuText;
    }

    public void setFuText(int fuText) {
        this.fuText = findViewById(fuText);
    }


    public ImageButton getFuSettingButton() {
        return fuSettingButton;
    }

    public void setFuSettingButton(int fuSettingButton) {
        this.fuSettingButton = findViewById(fuSettingButton);
    }
    public int getTextSize() {
        return textSize;
    }

    public void setTextSize(int textSize) {
        this.textSize = textSize;
    }


    public Button getFuButton() {
        return fuButton;

    public FuView() {
        super();

建立第一章 家族介绍

结构

包含两大家族宇轩和夫，同样是通过Intent进行交互，不过为他们设置了不同的图标，在drawable文件夹下放置了需要使用的图片，使用的时候将其通过id引用。
