我无法让这个进度条正常工作。任何人都可以帮助我了解来源,我有什么遗漏吗?
web = (WebView) findViewById(R.id.webview01);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
web.setWebViewClient(new myWebClient());
//ADDING THIS RESOLVED THE PROGRESS BAR ACTUALLY LOADING.
web.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
progressBar.setProgress(progress); }
});
//ADDING THIS RESOLVED THE PROGRESS BAR ACTUALLY LOADING.
WebSettings websettings = web.getSettings();
websettings.setBuiltInZoomControls(true);
websettings.setUseWideViewPort(true);
websettings.setJavaScriptEnabled(true);
websettings.setAllowFileAccess(true);
websettings.setDomStorageEnabled(true);
websettings.setLoadWithOverviewMode(true);
websettings.setSavePassword(true);
web.loadUrl("http://www.google.com");
然后在后面的代码中
//Loading the Actual Webpage
public class myWebClient extends WebViewClient
{
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
progressBar.setVisibility(View.VISIBLE);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
progressBar.setVisibility(View.VISIBLE);
return true;
}
//web.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
progressBar.setProgress(progress);
}
@Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
}
webview 本身工作得很好,我只是想有一个水平加载栏,类似于 dolphin、chrome 等浏览器。
这是布局。

我没有收到任何错误或问题,所以没有 logcat,它只是实际加载,它在网页加载时显示进度条,但没有动画或实际加载移动。
