android > WebView > 加载完整网页

先是布局文件 main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >            <ImageView        android:id="@+id/wel_bg"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:contentDescription="@android:string/cancel"        android:scaleType="fitXY" />        <WebView        android:id="@+id/wv1"        android:layout_width="fill_parent"        android:layout_height="fill_parent"  />            </LinearLayout>

再是主 activity

package jin.com;import java.util.Timer;import java.util.TimerTask;import android.app.Activity;import android.app.ProgressDialog;import android.content.res.Resources;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.os.Bundle;import android.view.View;import android.webkit.WebView;import android.webkit.WebViewClient;import android.widget.ImageView;public class JinActivity extends Activity {    /** Called when the activity is first created. */private WebView wv;private ProgressDialog pd;private ImageView wel_bg;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        //////        Resources res = getResources();          Bitmap imgB = BitmapFactory.decodeResource(res, R.drawable.beijing);               wel_bg = (ImageView)findViewById(R.id.wel_bg);        wel_bg.setImageBitmap(imgB);        ///\\                wv = (WebView) findViewById(R.id.wv1);        wv.getSettings().setJavaScriptEnabled(true);        wv.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);        wv.setWebViewClient(new WebViewClientDemo());        wv.getSettings().setSupportZoom(false); // 不支持页面放大功能        wv.requestFocus();                if(wv != null)        {        wv.setWebViewClient(new WebViewClient()        {        @Override        public void onPageFinished(WebView view,String url)        {        //pd.dismiss();        wel_bg.setVisibility(8); //加载完成后，ImageView 隐藏        //execute the task          //wv.setVisibility(0); //0: 显示， 8 隐藏 ; 4 意思是不可见的，但还占着原来的空间 /                }        });                loadUrl("http://218.94.151.67:8099/jincheng");        }                }    private class WebViewClientDemo extends WebViewClient {                // 在WebView中而不是默认浏览器中显示页面        public boolean shouldOverrideUrlLoading(WebView view, String url) {            view.loadUrl(url);            return true;        }    }    public void loadUrl(String url)    {    if(wv != null)    {    wv.loadUrl(url);    //wel_bg.setVisibility(0);    //wv.setVisibility(8);    //pd = ProgressDialog.show(this, "提示", "加载中.....");    wv.reload();    }    }                }
