原理：重寫WebViewClient的onPageFinished方法，在onPageFinished中加載一段js代碼，js代碼再調用本地方法

用下面的方法可以獲取網頁的html源碼import?android.app.Activity;

import?android.graphics.Bitmap;

import?android.os.Bundle;

import?android.util.Log;

import?android.webkit.WebView;

import?android.webkit.WebViewClient;

public?class?HtmlSource?extends?Activity?{

private?WebView?webView;

/**?Called?when?the?activity?is?first?created.?*/

@Override

public?void?onCreate(Bundle?savedInstanceState)?{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

webView?=?(WebView)findViewById(R.id.webview);

webView.getSettings().setJavaScriptEnabled(true);

webView.addJavascriptInterface(new?InJavaScriptLocalObj(),?"local_obj");

webView.setWebViewClient(new?MyWebViewClient());

webView.loadUrl("http://www.cnblogs.com/hibraincol/");

}

final?class?MyWebViewClient?extends?WebViewClient{

public?boolean?shouldOverrideUrlLoading(WebView?view,?String?url)?{

view.loadUrl(url);

return?true;

}

public?void?onPageStarted(WebView?view,?String?url,?Bitmap?favicon)?{

Log.d("WebView","onPageStarted");

super.onPageStarted(view,?url,?favicon);

}

public?void?onPageFinished(WebView?view,?String?url)?{

Log.d("WebView","onPageFinished?");

view.loadUrl("javascript:window.local_obj.showSource('

'+"?+

"document.getElementsByTagName('html')[0].innerHTML+'');");

super.onPageFinished(view,?url);

}

}

final?class?InJavaScriptLocalObj?{

public?void?showSource(String?html)?{

Log.d("HTML",?html);

}

}

}
