由于文笔有限，写的不好，大家多见谅，以后坚持写，提高自己的语言表达沟通能力。
在
Cocos2dxActivity中添加一个方法：
public LinearLayout onCreateLayout(Cocos2dxGLSurfaceView sufaceView){
LinearLayout layout = new LinearLayout(this);
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setLayoutParams(lp);
return layout;
}
在init()方法中这行代码framelayout.addView(this.mGLSurfaceView);下面添加两行代码
LinearLayout contentLayout = this.onCreateLayout(mGLSurfaceView);
framelayout.addView(contentLayout);
然后在src文件夹中的主activity中添加四个变量
public static MyActivity contextInstance;//主activity的静态实例
private static LinearLayout mContentLayout;
private static LinearLayout mWebLayout;
private static WebView mWebView;
在oncreate方法中添加一句：contextInstance = this；
然后重写 onCreateLayout方法
public LinearLayout onCreateLayout(Cocos2dxGLSurfaceView surfaceView) {mContentLayout = new LinearLayout(this);mContentLayout.setOrientation(LinearLayout.VERTICAL);mWebLayout = new LinearLayout(this);mWebLayout.setOrientation(LinearLayout.VERTICAL);return mContentLayout;}
写一个静态方法，弹出网页
public static void showTanChuTiShi(final float x, final float y,final float width, final float height, final int operateIndex,final String linkUrl, final int showWay) {contextInstance.runOnUiThread(new Runnable() {// 在主线程里添加别的控件public void run() {int screenw = screenWidth;int newx = 0;int newy = 0;newx = (int) (screenw * x / 480.0);newy = (int) (screenw * y / 480.0);int newwidth = (int) (screenw * width / 480.0);int newheight = (int) (screenw * height / 480.0);LinearLayout.LayoutParams lp = new LayoutParams((int) newwidth, (int) newheight);lp.leftMargin = newx;lp.topMargin = newy;// 初始化webViewmWebView = new WebView(contextInstance);mWebView.setBackgroundColor(0);// 设置webView能够执行javascript脚本// mWebView.getSettings().setJavaScriptEnabled(true);// 载入URL// mWebView.loadUrl("file:///android_asset/index.html");WebSettings tishisetting = mWebView.getSettings();tishisetting.setJavaScriptEnabled(true);tishisetting.setUseWideViewPort(true);tishisetting.setLoadWithOverviewMode(true);// 使页面获得焦点// mWebView.requestFocus();// 如果页面中链接，如果希望点击链接继续在当前browser中响应
mWebView.setWebViewClient(new WebViewClient() {@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {view.loadUrl(url);return true;}
@Overridepublic void onPageFinished(WebView view, String url) {super.onPageFinished(view, url);// webView.requestFocus();}
@Overridepublic void onPageStarted(WebView view, String url,Bitmap favicon) {super.onPageStarted(view, url, favicon);}
@Overridepublic void onReceivedError(WebView view,int errorCode, String description,String failingUrl) {// TODO Auto-generated method stubsuper.onReceivedError(view, errorCode,description, failingUrl);}});
mWebView.setWebChromeClient(new WebChromeClient() {@Overridepublic void onProgressChanged(WebView view,int progress) {}});
mWebView.loadUrl(linkUrl);
// 把webView加入到线性布局mContentLayout.addView(mWebLayout,lp);LinearLayout.LayoutParams lp0 = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);mWebLayout.addView(mWebView, lp0);}});}
再写一个关闭网页的方法
public static void dismisWebView() {contextInstance.runOnUiThread(new Runnable() {// 在主线程里添加别的控件public void run() {if (mWebView != null) {mContentLayout.removeView(mWebLayout);mWebLayout.destroyDrawingCache();
mWebLayout.removeView(mWebView);mWebView.destroy();}}});}写一个C++的AndroidClassHelper类，在源文件中添加一个调用android主activity中的 showTanChuTiShi的方法
void AndroidClassHelper::creatWeblayerInRect(float rx, float ry, float rw, float rh, const char* alertUrl, int vt) {CCLOG("%s%s",__FUNCTION__,alertUrl);//调用jni方法 调用系统浏览器打开urlStrJniMethodInfo minfo;//定义Jni函数信息结构体 //getStaticMethodInfo 次函数返回一个bool值表示是否找到此函数 bool isHave = JniHelper::getStaticMethodInfo(minfo, "com/practice/activity/MyActivity", "showTanChuTiShi","(FFFFILjava/lang/String;I)V"); if (!isHave) { CCLog(" jni:此函数不存在"); }else{ CCLog("jni:此函数存在"); jstring stringArg1 = minfo.env->NewStringUTF(alertUrl); //调用此函数 minfo.env->CallStaticVoidMethod(minfo.classID, minfo.methodID, rx, ry, rw, rh, at,stringArg1,vt); minfo.env->DeleteLocalRef(stringArg1); minfo.env->DeleteLocalRef(minfo.classID); } CCLog("jni-java函数执行完毕"); /** */}再在源文件中添加一个调用android主activity中的 dismisWebView的方法
void AndroidClassHelper::destoryWeblayer() {CCLog("%s",__FUNCTION__);//调用jni方法 调用系统浏览器打开urlStrJniMethodInfo minfo;//定义Jni函数信息结构体 //getStaticMethodInfo 次函数返回一个bool值表示是否找到此函数 bool isHave = JniHelper::getStaticMethodInfo(minfo, "com/practice/activity/MyActivity", "dismisWebView","()V"); if (!isHave) { CCLog("dismisWebView jni:此函数不存在"); }else{ CCLog("dismisWebView jni:此函数存在"); //调用此函数 minfo.env->CallStaticVoidMethod(minfo.classID, minfo.methodID); minfo.env->DeleteLocalRef(minfo.classID); } CCLog("dismisWebView jni-java函数执行完毕"); /** */}
然后就可以按照自己的需要在C++其他类中调用AndroidClassHelper::creatWeblayerInRect弹出网页和AndroidClassHelper::destoryWeblayer() 来关闭网页了
