activity_main.xml程式碼，例如：

<?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中的程式碼如下：

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);
        //設定WebView屬性，能夠執行JavaScript指令碼
 

        webview.getSettings().setJavaScriptEnabled(true);
        //設定渲染（必須）
        webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        webview.setWebChromeClient(new WebChromeClient());
        //載入URL內容
        webview.loadUrl("http://webapp.cbd88.cn/");
        //設定web檢視客戶端
        webview.setWebViewClient(new MyWebViewClient());
    }
    //設定回退
    public boolean onKeyDown(int keyCode,KeyEvent event)
    {
            if((keyCode==KeyEvent.KEYCODE_BACK)&&webview.canGoBack())
            {
                    webview.goBack();
                    return true;
            }
            return super.onKeyDown(keyCode,event);
    }
    //web檢視客戶端
    public class MyWebViewClient extends WebViewClient
    {
            public boolean shouldOverviewUrlLoading(WebView view,String url)
            {
                    view.loadUrl(url);
                    return true;
            }
    }
}
