android cocoscreator 相互调用(三）
前言
前2章 讲述了 android 调用 c++ so库,这章主要讲在android cocoscreator 中java 与js 相互调用;
1 准备
win7 64
androidstudio4.1.1 cocoscreator2.4.4
2 创建工程并修改
1> cocoscreator 创建个 helloworld 工程
2 > UI 界面如下
3> 增加个JavaCallJs.js
代码如下
const JavaCallJs = {
getVau: function (datastr) {
if (cc.game) {
cc.game.labelstr = datastr;
}
}
}
module.exports = JavaCallJs;
4 > 修改HelloWord.js 如下
const JavaCallJs = require("JavaCallJs");
cc.Class({
extends: cc.Component,
properties: {
label: {
default: null,
type: cc.Label
},
// defaults, set visually when attaching this script to the Canvas
text: 'Hello, World!',
inputfun:{
default:null,
type:cc.EditBox
},
inputparam:{
default:null,
type:cc.EditBox
},
inputrealparamcount:{
default:null,
type:cc.EditBox
},
inputrealparams:{
default:null,
type:cc.EditBox
},
button:{
default:null,
type:cc.Button
},
output:cc.Label
},
// use this for initialization
onLoad: function () {
this.label.string = this.text;
},
start:function(){
if (cc.sys.isNative && jsb != null && jsb != "undefined") {
this.output.string ="jsb function is vaild";

}else if (!cc.game.JavaCallJs){

this.outputlog("cc.game.JavaCallJs set[2]");
}
},
// called every frame
update: function (dt) {
},
//日志输出
outputlog:function(){//可变参数 arguments

/*
目前 Cocos Creator 中支持的 Java 类型签名有下面 4 种：
Java类型 签名
int I
float F
boolean Z
String Ljava/lang/String;
*/
3 编译
1> 构建工程
2> 用AndroidStudio 打开 jsb-default\frameworks\runtime-src\proj.android-studio
修改AppActivity.java
代码如下:

4 测试
1：js call java
点击OK，结果正确，调用成功
1 > java call js
2 > 点击OK， js call java call js (js调用java函数,java函数里由调用js函数)
3> 点击bjvcalljs 查看结果
String params = String.format("cc.game.JavaCallJs.getVau(\"%s\")",String.valueOf(a*2));
Cocos2dxJavascriptJavaBridge.evalString(params);
5 js 与 java 调用完成
工程代码如有需要后续再上传
