Mih*_*ala 8 html android android-webview
在使用锚链接加载html内容时,我在webview中面临一些奇怪的问题.
以下代码适用于锚标记,但只适用一次.
第二次当我按下锚标签时它不起作用.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mywebview);
String html = "<html><body><p><a href='#C4'>See also Chapter 4</a></p><p><h2>Chapter 1</h2><p>This chapter explains ba bla bla</p><h2>Chapter 2</h2><p>This chapter explains ba bla bla</p><h2>Chapter 3</h2><p>This chapter explains ba bla bla</p><h2><a name='C4'>Chapter 4</a></h2><p>This chapter explains ba bla bla</p><h2>Chapter 5</h2><p>This chapter explains ba bla bla</p><h2>Chapter 6</h2><p>This chapter explains ba bla bla</p><h2>Chapter 7</h2><p>This chapter explains ba bla bla</p><h2>Chapter 8</h2><p>This chapter explains ba bla bla</p><h2>Chapter 9</h2><p>This chapter explains ba bla bla</p></body></html>";
String mime = "text/html";
String encoding = "utf-8";
WebView myWebView = (WebView)this.findViewById(R.id.webView1);
myWebView.loadDataWithBaseURL(null, html, mime, encoding, null);
}
我试过这个链接,但没有为我工作.
更新:
在各种设备中测试我的代码的结果.
工作
1.三星S Plus - > 2.3.4
2.三星Galaxy Y - > 2.3.6
3.三星Galaxy Tab - > 2.3.3
4.摩托罗拉Xoom - > 3.2
不工作
1. LG Optimus - > 2.2
2. DELL XCD35(中兴刀片) - > 2.2
3. HTC WildFire - > 2.2.1
这是操作系统问题还是别的？任何解决方案？

问题是在Anchor link点击后再次重新加载页面.
我使用了以下代码,
Assets文件夹中的chapters.xml
<html>
<body>
<p><a href="#C4">See also Chapter 4</a></p>
<p><h2><a name='C1'>Chapter 1<a></h2><p>This chapter explains ba bla bla</p>
<h2>Chapter 2</h2><p>This chapter explains ba bla bla</p>
<h2>Chapter 3</h2><p>This chapter explains ba bla bla</p>
<h2><a name='C4'>Chapter 4</a></h2><p>This chapter explains ba bla bla</p>
<h2>Chapter 5</h2><p>This chapter explains ba bla bla</p>
<h2>Chapter 6</h2><p>This chapter explains ba bla bla</p>
<h2>Chapter 7</h2><p>This chapter explains ba bla bla</p>
<a href="#C1">See also Chapter 1</a>
</body>
</html>
JAVA代码:First Way
public class MainActivity extends Activity {
WebView myWebView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myWebView = new WebView(this);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.loadUrl("file:///android_asset/chapters.html");
setContentView(myWebView);
final GestureDetector gestureDetector = new GestureDetector(
new MyGestureDetector());
View.OnTouchListener gestureListener = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
};
myWebView.setOnTouchListener(gestureListener);
}
class MyGestureDetector extends SimpleOnGestureListener {
@Override
public boolean onSingleTapConfirmed(MotionEvent e) {
myWebView.reload();
Log.i("", "Reload");
return super.onSingleTapConfirmed(e);
}
}
}
编辑JAVA代码:第二种方式 - 我试过这个东西,onTouchListener并且对我来说工作正常.
public class MainActivity extends Activity {
WebView myWebView;
public static boolean flag = false;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myWebView = new WebView(this);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.loadUrl("file:///android_asset/chapters.html");
setContentView(myWebView);
myWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
if (url.contains("#") && flag == false) {
myWebView.loadUrl(url);
flag = true;
} else {
flag = false;
}
}
});
}
}
从一个文件打开另一个HTML文件的锚标记
myWebView = new WebView(this);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.loadUrl("file:///android_asset/1.htm");
myWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
try{
chapter = url.substring(url.indexOf("#"),url.length());
url = url.substring(0,url.indexOf("#"));
}catch (Exception e) {
chapter = "";
}
myWebView.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
if (!chapter.equalsIgnoreCase("") && flag == false) {
myWebView.loadUrl(url+chapter);
flag = true;
} else {
flag = false;
}
}
});
setContentView(myWebView);
