Ionic 5 - 如何更换默认图标和闪屏图像并生成资源。

Question

我最近开始使用ionic 6和cac capacitor(不是cordova)，我不知道如何替换它的默认应用图标和闪屏，有没有办法像cordova那样使用ionic capacitor cli生成资源？有沒有辦法像以前用c capacitor cli(ionic cordova resources android)一樣，用ionic capacitor cli產生資源，用我自己的圖像代替呢？ 用c capacitor(ionic cap add android)加入android平台後，在android資源中產生圖像和flash圖像，但我不知道如何代替我自己的圖像。

Answer 1

自动调整图标和闪屏大小的CLI工具，用于基于电容器的应用程序。

它可以自动调整您的图标.png和闪屏.png文件的大小，并将其复制到平台专用目录中。

它不需要任何外部二进制库。仅使用Javascript。

安装方法

$ npm install capacitor-resources -g

使用方法

所需文件将你的icon.png (1024x1024 px)和splash.png (2732x2732 px)文件添加到基于电容的项目根目录下的 "资源 "文件夹中。

$ capacitor-resources

https:/www.npmjs.compackagecapacitor-resources

Answer 2

我用电容-资源和下面这个脚本解决了这个问题。在你的根目录下保存为resources.js。然后在你的package.json文件的脚本下添加。

"resources": "capacitor-resources -p android,ios && node resources.js",

const fs = require('fs');

function copyImages(sourcePath, targetPath, images) {
  for (const icon of images) {
    let source = sourcePath + icon.source;
    let target = targetPath + icon.target;
    fs.copyFile(source, target, err => {
      if (err) throw err;
      console.log(`${source} >> ${target}`);
    });
  }
}

const SOURCE_ANDROID_ICON = 'resources/android/icon/';
const SOURCE_ANDROID_SPLASH = 'resources/android/splash/';

const TARGET_ANDROID_ICON = 'android/app/src/main/res/';
const TARGET_ANDROID_SPLASH = 'android/app/src/main/res/';

const ANDROID_ICONS = [
