Question

I have installed this plugin to my PhoneGap project :

https://github.com/phonegap/phonegap-plugin-barcodescanner

It works like a charm. However, I want to be able to have some buttons on whilst the scanner is open to navigate the app. This is so when the app opens the scanner opens straight away so they can scan barcodes straight away and then have a button somewhere where they can go in to the app.

I have tried looking inside the plugin javascript etc but all it has is one javascript file as shown below:

cordova.define("phonegap-plugin-barcodescanner.BarcodeScanner", function(require, exports, module) { /**

var exec = require("cordova/exec");

/**

 *
 * @returns {BarcodeScanner}

function BarcodeScanner() {

    /**
     * Encoding constants.
     *
     * @type Object

    this.Encode = {
        TEXT_TYPE: "TEXT_TYPE",

Android的Phonegap条形码扫描程序插件只是在Phonegap和ZXing项目之间提供了一个界面。它是Android的ZXing客户端，它定义了在“扫描模式”下显示的用户界面，这是本地（在Java中）而不是Javascript。

要更改它，您需要编辑插件使用的library project并在那里更改本机UI代码。
