檢查一下webview的方法調(diào)用對(duì)沒有！
網(wǎng)頁腳本js運(yùn)行出錯(cuò)，webView.setWebViewClient用WebViewClient的onPageFinished（WebView view, String url）方法會(huì)監(jiān)聽到網(wǎng)頁加載完成，如果顯示不完整，就應(yīng)該去找網(wǎng)頁怎么寫的。

WebViewClient的方法說明
1、public
boolean shouldOverrideUrlLoading(WebView view, String url) {

view.loadUrl(url);

return true;

}

在點(diǎn)擊請(qǐng)求的是鏈接是才會(huì)調(diào)用，重寫此方法返回true表明點(diǎn)擊網(wǎng)頁里面的鏈接還是在當(dāng)前的webview里跳轉(zhuǎn)，不跳到瀏覽器那邊。
2、public
void onReceivedSslError(WebView view, SslErrorHandler handler,
android.net.http.SslError error) {
handler.proceed();
}
重寫此方法可以讓webview處理https請(qǐng)求。
3、public
boolean shouldOverrideKeyEvent(WebView view, KeyEvent event) {

return super.shouldOverrideKeyEvent(view, event);

}

}
重寫此方法才能夠處理在瀏覽器中的按鍵事件。
4、
public void onLoadResource(WebView view, String url) {

// TODO Auto-generated method stub

if (DEBUG) {

Log.d(TAG, " onLoadResource ");

}

super.onLoadResource(view, url);

}
在加載頁面資源時(shí)會(huì)調(diào)用，每一個(gè)資源（比如圖片）的加載都會(huì)調(diào)用一次。
5、
public void onPageStarted(WebView view, String url, Bitmap favicon) {

// TODO Auto-generated method stub

if (DEBUG) {

Log.d(TAG, " onPageStarted ");

}

if (url.endsWith(".apk")) {

download(url);//下載處理

}

super.onPageStarted(view, url, favicon);

}
在頁面加載開始時(shí)調(diào)用。
6、public
void onPageFinished(WebView view, String url) {

// TODO Auto-generated method stub

if (DEBUG) {

Log.d(TAG, " onPageFinished ");

}

super.onPageFinished(view, url);

}
在頁面加載結(jié)束時(shí)調(diào)用。
webview介紹的原文如下：A View that displays web pages. This class is the basis upon which you can roll your own web browser or simply display some online content within your Activity. It uses the WebKit rendering engine to display web pages and includes methods to navigate forward and backward through a history, zoom in and out, perform text searches and more.
從上面你應(yīng)該了解到了基本功能，也就是顯示網(wǎng)頁。之所以我說webview功能強(qiáng)大是因?yàn)樗蚸s的交互非常方便，很簡(jiǎn)單就可以實(shí)現(xiàn)。

UIWebView加載工程本地網(wǎng)頁與本地圖片

- (void)viewDidLoad
{
[super viewDidLoad];

NSString *filePath = [[NSBundle mainBundle]pathForResource:@"1" ofType:@"html"];
NSString *htmlString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];

myWebView = [[UIWebView alloc] initWithFrame:self.view.bounds];
myWebView.delegate = self;
[self.view addSubview:myWebView];

[myWebView loadHTMLString:htmlString baseURL:[NSURL URLWithString:filePath]];

}

-(void)webViewDidFinishLoad:(UIWebView *)webView
{
NSString *imagePath = [[NSBundle mainBundle] resourcePath];
imagePath = [imagePath stringByReplacingOccurrencesOfString:@"/" withString:@"//"];
imagePath = [imagePath stringByReplacingOccurrencesOfString:@" " withString:@"%20"];
NSString * js = [NSString stringWithFormat:@"document.images[0].src='file:/%@//%@'",imagePath,@"icon-04.png"];

[myWebView stringByEvaluatingJavaScriptFromString:js];
NSString *path = [myWebView stringByEvaluatingJavaScriptFromString:@"document.images[0].src"];
NSLog(@"path:%@", path);
}

android中只需要給webView注冊(cè)一個(gè)事件即可實(shí)現(xiàn)加載進(jìn)度。
以下是具體實(shí)現(xiàn)代碼：
1.從webView中獲取設(shè)置
WebSettings sws = webView.getSettings();
sws.setSupportZoom(true);
sws.setBuiltInZoomControls(true);
webView.setInitialScale(25);
webView.getSettings().setUseWideViewPort(true);

2.注冊(cè)setWebChromeClient事件
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// Activity和Webview根據(jù)加載程度決定進(jìn)度條的進(jìn)度大小
// 當(dāng)加載到100%的時(shí)候 進(jìn)度條自動(dòng)消失
//WebViewProgressActivity.this.setTitle("Loading...");
//WebViewProgressActivity.this.setProgress(progress * 100);
if (progress == 100) {
progressBar.setVisibility(View.GONE);
//WebViewProgressActivity.this.setTitle("完成");
}
}
});

3.注意在onProgressChanged中處理進(jìn)度，progress就是進(jìn)度值。
