在加载html内容和锚链接时,我在webview中面临一些奇怪的问题.
以下代码完美的锚标签,但只有一次.
第二次当我按下锚标签它不工作.

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this链接,但没有为我工作.
更新：
测试我的代码在各种设备中的结果.
加工
三星S Plus – > 2.3.4
三星galaxy Y – > 2.3.6
三星galaxy Tab – > 2.3.3
摩托罗拉Xoom – > 3.2
不工作
LG Optimus – > 2.2
DELL XCD35(中兴刀片) – > 2.2
3. HTC WildFire – > 2.2.1
这个操作系统问题还是其他的？任何解决方案？
解决方法
问题是在Anchor链接点击后重新加载页面.
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：第一路
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 – 我已经尝试了这个东西instt onTouchListener,并为我工作正常.
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文件的锚点标签
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);
