用eclipse把h5打包成安卓apk

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>

在MainActivity中的代码如下：

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends Activity {
/** Called when the activity is first created. */
private WebView webview;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
webview=(WebView)findViewById(R.id.webview);
//设置WebView属性，能够执行JavaScript脚本
webview.getSettings().setJavaScriptEnabled(true);
//设置渲染（必须）
webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webview.setWebChromeClient(new WebChromeClient());
//加载URL内容
webview.loadUrl("http://webapp.cbd88.cn/");
//设置web视图客户端
webview.setWebViewClient(new MyWebViewClient());
}
//设置回退
public boolean onKeyDown(int keyCode,KeyEvent event)
{
if((keyCode==KeyEvent.KEYCODE_BACK)&&webview.canGoBack())
{
webview.goBack();
return true;
}
return super.onKeyDown(keyCode,event);
}
//web视图客户端
public class MyWebViewClient extends WebViewClient
{
public boolean shouldOverviewUrlLoading(WebView view,String url)
{
view.loadUrl(url);
return true;
}
}
}
