安卓：HTML锚链接的作品只有一次在web视图 [英] Android : Html Anchor Link works only once in webview
问题描述
我面临着一些奇怪的问题，在web视图在加载HTML内容的锚链接时。
继code可以完美锚标记，但一次。
当我preSS锚标记是不工作第二次。
I am facing some strange issue in webview at time of loading html content with anchor link.
Following code works perfect for anchor tag but only once.
Second time when i press anchor tag it is not working.
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);
}
我已经尝试<一href="http://stackoverflow.com/questions/3039555/android-webview-anchor-link-jump-link-not-working">this链接，但不是为我工作。
i have tried this link but not worked for me.

推荐答案
问题是后锚链接点击再次刷新页面。
The problem was to Reload the Page again after Anchor link Click.
我使用了下列code，
I have used the following code,
chapters.xml资产的文件夹
chapters.xml in Assets folder
<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 code：第一种方式
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 code：第二种方式 - 我已经试过这件事情insted的 onTouchListener 和工作对我罚款。
EDIT JAVA CODE : Second Way - I have tried this thing insted onTouchListener and that working fine for me.
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;
}
}
});
}
}
从一个文件中打开另一个HTML文件的定位标记
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);
