标签:android 给webview添加漂亮的加载进度条
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="utf-8"?>
<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:
