【COCOS2DX-ANDROID-游戏开发之二三】 界面中嵌入Android的WebView

（转载请注明原文地址：http://blog.csdn.net/guggy/article/details/10435157）

在Cocos2dxActivity.java中,
(1) 增加函数onCreateLayout，

[java] view
plaincopy

public LinearLayout onCreateLayout(Cocos2dxGLSurfaceView surfaceView) {

LinearLayout layout = new LinearLayout(this);

layout.setOrientation(LinearLayout.VERTICAL);

layout.addView(surfaceView);

return layout;

}

(2) 在 this.mGLSurfaceView = this.onCreateView() 下面增加这一行：

[java] view
plaincopy

LinearLayout contentLayout = this.onCreateLayout(mGLSurfaceView);

(3) 应用的Activity文件实现如下，

[java] view
plaincopy

public class HelloCpp extends Cocos2dxActivity{

static HelloCpp sHelloCpp = null;

LinearLayout mContentLayout;

Cocos2dxGLSurfaceView mGlSurfaceView;

LinearLayout mWebLayout;

WebView mWebView;

Button mBackButton;



protected void onCreate(Bundle savedInstanceState){

super.onCreate(savedInstanceState);

}



public LinearLayout onCreateLayout(Cocos2dxGLSurfaceView surfaceView) {

mGlSurfaceView = surfaceView;

sHelloCpp = this;



mContentLayout = new LinearLayout(this);

mContentLayout.setOrientation(LinearLayout.VERTICAL);

mContentLayout.addView(surfaceView);



mWebLayout = new LinearLayout(this);

mWebLayout.setOrientation(LinearLayout.VERTICAL);



return mContentLayout;

}



public Cocos2dxGLSurfaceView onCreateView() {

Cocos2dxGLSurfaceView glSurfaceView = new Cocos2dxGLSurfaceView(this);

// TestCpp should create stencil buffer

glSurfaceView.setEGLConfigChooser(5, 6, 5, 0, 16, 8);



return glSurfaceView;

}



//此函数提供给jni调用，返回自身类的对象

public static HelloCpp getInstance() {//返回实例

return sHelloCpp;

}



public void openWebView() {

this.runOnUiThread(new Runnable() {//在主线程里添加别的控件

public void run() {

//初始化webView

mWebView = new WebView(HelloCpp.this);

//设置webView能够执行javascript脚本

mWebView.getSettings().setJavaScriptEnabled(true);

//载入URL

mWebView.loadUrl("file:///android_asset/index.html");

//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(){

public boolean shouldOverrideUrlLoading(WebView view, String url) {

if(url.indexOf("tel:")<0){

view.loadUrl(url);

}

return true;

}

});



/*初始化返回按钮*/

mBackButton = new Button(HelloCpp.this);

mBackButton.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));

mBackButton.setText("Close");

mBackButton.setTextColor(Color.argb(255, 255, 218, 154));

mBackButton.setTextSize(14);

mBackButton.setOnClickListener(new OnClickListener() {

public void onClick(View v) {

removeWebView();

mGlSurfaceView.setVisibility(View.VISIBLE);

}

});



//把webView加入到线性布局

mGlSurfaceView.setVisibility(View.GONE);

mWebLayout.addView(mBackButton);

mWebLayout.addView(mWebView);

mContentLayout.addView(mWebLayout);

}

});

}

//移除webView 把刚才加的所有控件都删掉

public void removeWebView() {

mContentLayout.removeView(mWebLayout);

mWebLayout.destroyDrawingCache();



mWebLayout.removeView(mWebView);

mWebView.destroy();



mWebLayout.removeView(mBackButton);

mBackButton.destroyDrawingCache();

}



public boolean onKeyDown(int keyCoder,KeyEvent event) //重载函数，android手机实体返回键回调函数

{

if(mWebView.canGoBack() && keyCoder == KeyEvent.KEYCODE_BACK){//如果网页能回退则后退，如果不能后退移除WebView

mWebView.goBack();

}else{

removeWebView();

mGlSurfaceView.setVisibility(View.VISIBLE);

}

return false;

}



static {

System.loadLibrary("game");

}

从cocos2d-x的界面中打开WebView的代码：

[cpp] view
plaincopy

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)

//getStaticMethodInfo，判断Java静态函数是否存在，并且把信息保存到minfo里

//参数1：JniMethodInfo

//参数2：Java类包名+类名

//参数3：Java函数名称

//参数4：函数参数类型和返回值类型，这里的返回值类型是HelloCpp类的对象。写法：L+包名+; 其他的类型请看上面的“JNI详细教程”



JniMethodInfo minfo;

jobject jobj;

bool isHave = JniHelper::getStaticMethodInfo(minfo, "cn/livelog/popdiamond/HelloCpp","getInstance","()Lcn/livelog/popdiamond/HelloCpp;");

if (isHave)

{

//调用Java静态函数，取得对象。

jobj = minfo.env->CallStaticObjectMethod(minfo.classID, minfo.methodID);

if (jobj != NULL)

{

isHave = JniHelper::getMethodInfo(minfo,"cn/livelog/popdiamond/HelloCpp","openWebView","()V");

if (isHave)

{

//调用java非静态函数, 参数1：Java对象，上面已经取得 参数2：方法ID

minfo.env->CallVoidMethod(jobj, minfo.methodID);

}

}

}

#endif
