Android : Html Anchor Link works only once in webview

The problem was to Reload the Page again after Anchor link Click.

I have used the following code,

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 : 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);

        }
    }
}

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;
                }
            }

        });
    }
}

To Open Another HTML File’s Anchor Tag from One file

        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);
