前言
前2章 讲述了 android 调用 c++ so库,这边主要讲在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{
this.outputlog("jsb function is invaild");
}
if (!cc.game) {
cc.game = {};
cc.game.JavaCallJs = JavaCallJs;
this.outputlog("cc.game.JavaCallJs set[1]");
}else if (!cc.game.JavaCallJs){
cc.game.JavaCallJs = 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
if(cc.sys.isNative && cc.sys.platform == cc.sys.OS_ANDROID){
const cAppActivity = "org/cocos2dx/javascript/AppActivity";
let strlog="";
for (var i=0; i 0 && self.inputrealparams.string.length > 0){

this.outputlog("ss1.length=",ss1.length,"ss2.length=",ss2.length);
if(ss1.length == ss2.length){
for (let i=0;i 0){
this.outputlog("realinput fun0",""+realinput[0]);
}
let outputstr = "";
const cAppActivity = "org/cocos2dx/javascript/AppActivity";
if(rtnpm.indexOf("V") >= 0){
//无返回参数
this.outputlog("rtnpm",rtnpm,"无参数返回");
switch(realinput.length){
case 0: jsb.reflection.callStaticMethod(cAppActivity,funstr,funparamstr); break;
case 1: jsb.reflection.callStaticMethod(cAppActivity,funstr,funparamstr,realinput[0]); break;

default:
return ;
}
// jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity",inputfun.string,inputparam.string);
outputstr = "no return params";
}else{
//有返回参数
this.outputlog("rtnpm",rtnpm,"有参数返回");
let rtnv ;
switch(realinput.length){

if(isNaN(rtnv)){ //不是数字
if(typeof(rtnv) == 'string'){ //字符串{
outputstr = rtnv ;
}else if(typeof(rtnv) == 'object'){
outputstr = JSON.stringify(rtnv) ; //将对象转为字符串

//加上时间
let time = new Date();
self.output.string = time.toLocaleString() + " " + outputstr ;
}
}
}
}
break;
case "bjvcalljs":
self.showlable(cc.game.labelstr);
break;
}
}
///
});
3 编译
1> 构建工程
2> 用AndroidStudio 打开 jsb-defaultframeworksruntime-srcproj.android-studio
修改AppActivity.java
代码如下:
package org.cocos2dx.javascript;
import org.cocos2dx.lib.Cocos2dxActivity;
import org.cocos2dx.lib.Cocos2dxGLSurfaceView;
import org.cocos2dx.lib.Cocos2dxJavascriptJavaBridge;
import android.os.Bundle;
import android.content.Intent;
import android.content.res.Configuration;
import android.util.Log;
public class AppActivity extends Cocos2dxActivity {
private static AppActivity _app = null ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Workaround in
// https://stackoverflow.com/questions/16283079/re-launch-of-activity-on-home-button-but-only-the-first-time/16447508
if (!isTaskRoot()) {
// Android launched another instance of the root activity into an existing task
// so just quietly finish and go away, dropping the user back into the activity
// at the top of the stack (ie: the last state of this task)
// Don't need to finish it again since it's finished in super.onCreate .
return;
}
// DO OTHER INITIALIZATION BELOW
SDKWrapper.getInstance().init(this);
_app = this;
}
@Override
public Cocos2dxGLSurfaceView onCreateView() {
Cocos2dxGLSurfaceView glSurfaceView = new Cocos2dxGLSurfaceView(this);
// TestCpp should create stencil buffer
glSurfaceView.setEGLConfigChooser(5, 6, 5, 0, 16, 8);
SDKWrapper.getInstance().setGLSurfaceView(glSurfaceView, this);
return glSurfaceView;
}
@Override
protected void onResume() {
super.onResume();
SDKWrapper.getInstance().onResume();
}
@Override
protected void onPause() {
super.onPause();
SDKWrapper.getInstance().onPause();
}
@Override
protected void onDestroy() {
super.onDestroy();
// Workaround in https://stackoverflow.com/questions/16283079/re-launch-of-activity-on-home-button-but-only-the-first-time/16447508
if (!isTaskRoot()) {
return;
}
SDKWrapper.getInstance().onDestroy();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
SDKWrapper.getInstance().onActivityResult(requestCode, resultCode, data);
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
SDKWrapper.getInstance().onNewIntent(intent);
}
@Override
protected void onRestart() {
super.onRestart();
SDKWrapper.getInstance().onRestart();
}
@Override
protected void onStop() {
super.onStop();
SDKWrapper.getInstance().onStop();
}
@Override
public void onBackPressed() {
SDKWrapper.getInstance().onBackPressed();
super.onBackPressed();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
SDKWrapper.getInstance().onConfigurationChanged(newConfig);
super.onConfigurationChanged(newConfig);
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
SDKWrapper.getInstance().onRestoreInstanceState(savedInstanceState);
super.onRestoreInstanceState(savedInstanceState);
}
@Override
protected void onSaveInstanceState(Bundle outState) {
SDKWrapper.getInstance().onSaveInstanceState(outState);
super.onSaveInstanceState(outState);
}
@Override
protected void onStart() {
SDKWrapper.getInstance().onStart();
super.onStart();
}
public static int testfun1(int a,int b){
return a+b;
}
public static void systemoutput(String strlog){
System.out.println(strlog);
Log.d("AppActivity", strlog);
}
public static void testfun2(int a){
// AppActivity.this.test();
_app.test(a);
}
public void test(final int a){
//activity必须是继承自Cocos2dxActivity或者实现Cocos2dxHelperListener接口
this.runOnGLThread(new Runnable() {
@Override
public void run(){
String params = String.format("cc.game.JavaCallJs.getVau("%s")",String.valueOf(a*2));
Cocos2dxJavascriptJavaBridge.evalString(params);
}
});
}
}
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
