crosswalk工程建立及使用

crosswalk是一个开源项目，github可以找到源代码，是一个webView控件。这玩意弥补了webkit的不足，其实就是对于4.0到4.4版本的5.0的chromiun浏览器一个打包

crosswalk简介详情请见：http://dev.yesky.com/24/39285024.shtml

话不多说，上代码：



首先创建一个xml文件，内容如下：

完整copy进去。

next，

activity的layout图纸：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

<!-- <org.apache.cordova.CordovaWebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
></org.apache.cordova.CordovaWebView> -->

<com.example.webviews.IWeb
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>

</RelativeLayout>

非常简单，，然后整合代码：

为了做扩展，我们需要一个自定义的webView而不是源生的：

代码如下：

package com.example.webviews;

import org.apache.cordova.CordovaWebView;

import android.content.Context;
import android.util.AttributeSet;

public class IWeb extends CordovaWebView{

public IWeb(Context context) {
super(context);
}

public IWeb(Context context, AttributeSet attrs) {
super(context, attrs);
}

public IWeb(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}

public IWeb(Context context, AttributeSet attrs, int defStyle,
boolean privateBrowsing) {
super(context, attrs, defStyle, privateBrowsing);
}

}

activity代码：

package com.example.webviews;

import org.apache.cordova.CordovaActivity;
import org.apache.cordova.CordovaChromeClient;
import org.apache.cordova.CordovaWebView;
import org.apache.cordova.CordovaWebViewClient;
import android.annotation.SuppressLint;
import android.os.Bundle;
import android.webkit.JsResult;
import android.webkit.WebView;

@SuppressLint("SetJavaScriptEnabled")
public class MainActivity extends CordovaActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

appView = (CordovaWebView) findViewById(R.id.webview);

CordovaWebViewClient webClient = makeWebViewClient(appView);
CordovaChromeClient chromeClient = makeChromeClient(appView);
appView.getSettings().setJavaScriptEnabled(true);
appView.setWebViewClient(webClient);
appView.setWebChromeClient(chromeClient);
webClient.setWebView(appView);
chromeClient.setWebView(appView);

//		appView.loadUrl("http://www.hao123.com/?tn=95334564_hao_pg");
appView.loadUrlIntoView("http://wap.vip.com/");
//		loadUrl("http://www.hao123.com/?tn=95334564_hao_pg");
}

@Override
protected CordovaWebViewClient makeWebViewClient(CordovaWebView webView) {

CordovaWebViewClient client = new CordovaWebViewClient(this,appView){

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return super.shouldOverrideUrlLoading(view, url);
}
};

return client;
}

@Override
protected CordovaChromeClient makeChromeClient(CordovaWebView webView) {

CordovaChromeClient client = new CordovaChromeClient(this, appView){

@Override
public boolean onJsAlert(WebView view, String url, String message,
JsResult result) {
result.confirm();
return true;
}

};

return client;
}

}

OK了，，以上就大功告成了，，发现还缺一些东西，比如开源的代码库：

因为数量较多，我提供一个项目结构树跟下载!
