为了增强用户体验,所有在WebView头部给加了个进度条,看起来不错哦。

布局XMl:activity_main.xml

<?xml version="1.0" encoding="utf⑻"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <WebView android:id="@+id/webView" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <ProgressBar android:id="@+id/pb" style="?android:attr/progressBarStyleHorizontal" android:layout_width="fill_parent" android:layout_height="3dip" android:indeterminateOnly="false" android:max="100" android:progressDrawable="@drawable/progress_bar_states" > </ProgressBar> </RelativeLayout>

自定义进度条:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@android:id/background"> <shape> <corners android:radius="2dp" /> <gradient android:angle="270" android:centerColor="#E3E3E3" android:endColor="#E6E6E6" android:startColor="#C8C8C8" /> </shape> </item> <item android:id="@android:id/progress"> <clip> <shape> <corners android:radius="2dp" /> <gradient android:centerColor="#4AEA2F" android:endColor="#31CE15" android:startColor="#5FEC46" /> </shape> </clip> </item> </layer-list>

然后就是Activity的主要代码啦:

ProgressBar pb; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.xxx); pb = (ProgressBar) findViewById(R.id.pb); pb.setMax(100); WebView webView = (WebView) findViewById(R.id.webview); webView.getSettings().setJavaScriptEnabled(true); webView.getSettings().setSupportZoom(true); webView.getSettings().setBuiltInZoomControls(true); webView.setWebChromeClient(new WebViewClient() ); webView.loadUrl("http://www.x.com"); } private class WebViewClient extends WebChromeClient { @Override public void onProgressChanged(WebView view, int newProgress) { pb.setProgress(newProgress); if(newProgress==100){ pb.setVisibility(View.GONE); } super.onProgressChanged(view, newProgress); } }

不多说,知道大家最关心效果如何咯:
