我这样做，通过初步显示出了ImageView的再一次的WebView加载，交换​​这样的企业的知名度。

I do it by initially showing an ImageView and then once the WebView has loaded, swapping their visibility like this

        WebView wv = (WebView) findViewById(R.id.webView1);
        wv.getSettings().setJavaScriptEnabled(true);
        wv.setWebViewClient(new WebViewClient() {

            ...

            @Override
            public void onPageFinished(WebView view, String url) {
                //hide loading image
                findViewById(R.id.imageLoading1).setVisibility(View.GONE);
                //show webview
                findViewById(R.id.webView1).setVisibility(View.VISIBLE);
            }


        });     
        wv.loadUrl("http://yoururlhere.com");

和我的XML布局看起来像这样

And my xml layout looks like this

    <ImageView android:id="@+id/imageLoading1"
        android:layout_height="fill_parent"
        android:layout_width="fill_parent"
        android:visibility="visible"
        android:src="@drawable/vert_loading"
        />
    <WebView android:id="@+id/webView1"
        android:layout_height="fill_parent"
        android:layout_width="fill_parent"
        android:visibility="gone"
        />
