Thats because its tied to the web view not the button  I had the same problem after implementing  The button had no affect but the page in the web view did

I think you can also use MotionEvent ACTION UP state  example    Override public boolean onTouch View v  MotionEvent event        switch  v getId          case R id iv          if  event getAction      MotionEvent ACTION UP                if  isheadAndFootShow    false                    headLayout setVisibility View VISIBLE                   footLayout setVisibility View VISIBLE                   isheadAndFootShow   true                else                   headLayout setVisibility View INVISIBLE                   footLayout setVisibility View INVISIBLE                   isheadAndFootShow   false                            return true                    break             return false

I took a look at this and I found that a WebView doesn t seem to send click events to an OnClickListener  If anyone out there can prove me wrong or tell me why then I d be interested to hear it    What I did find is that a WebView will send touch events to an OnTouchListener  It does have its own onTouchEvent method but I only ever seemed to get MotionEvent ACTION MOVE using that method   So given that we can get events on a registered touch event listener  the only problem that remains is how to circumvent whatever action you want to perform for a touch when the user clicks a URL    This can be achieved with some fancy Handler footwork by sending a delayed message for the touch and then removing those touch messages if the touch was caused by the user clicking a URL    Here s an example   public class WebViewClicker extends Activity implements OnTouchListener  Handler Callback    private static final int CLICK ON WEBVIEW   1  private static final int CLICK ON URL   2   private final Handler handler   new Handler this    private WebView webView  private WebViewClient client    Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout web view clicker        webView    WebView findViewById R id web       webView setOnTouchListener this        client   new WebViewClient              Override public boolean shouldOverrideUrlLoading WebView view  String url                 handler sendEmptyMessage CLICK ON URL               return false                          webView setWebViewClient client       webView setVerticalScrollBarEnabled false       webView loadUrl  http   www example com        Override public boolean onTouch View v  MotionEvent event        if  v getId      R id web  amp  amp  event getAction      MotionEvent ACTION DOWN           handler sendEmptyMessageDelayed CLICK ON WEBVIEW  500             return false      Override public boolean handleMessage Message msg        if  msg what    CLICK ON URL           handler removeMessages CLICK ON WEBVIEW           return true            if  msg what    CLICK ON WEBVIEW           Toast makeText this   WebView clicked   Toast LENGTH SHORT  show            return true            return false         Hope this helps

You can implement an OnClickListener via OnTouchListener   webView setOnTouchListener new View OnTouchListener              public final static int FINGER RELEASED   0          public final static int FINGER TOUCHED   1          public final static int FINGER DRAGGING   2          public final static int FINGER UNDEFINED   3           private int fingerState   FINGER RELEASED             Override         public boolean onTouch View view  MotionEvent motionEvent                 switch  motionEvent getAction                       case MotionEvent ACTION DOWN                      if  fingerState    FINGER RELEASED  fingerState   FINGER TOUCHED                      else fingerState   FINGER UNDEFINED                      break                   case MotionEvent ACTION UP                      if fingerState    FINGER DRAGGING                            fingerState   FINGER RELEASED                              Your onClick codes                                            else if  fingerState    FINGER DRAGGING  fingerState   FINGER RELEASED                      else fingerState   FINGER UNDEFINED                      break                   case MotionEvent ACTION MOVE                      if  fingerState    FINGER TOUCHED    fingerState    FINGER DRAGGING  fingerState   FINGER DRAGGING                      else fingerState   FINGER UNDEFINED                      break                   default                      fingerState   FINGER UNDEFINED                              return false

WebViewClient shouldOverrideUrlLoading might be helpful  We are having a similar requirement in one of our app  Not tried yet

I have tried almost all the answers and some of them almost worked for me but none of these answers work perfectly  So here is my solution  For this solution  you will need to add onclick attribute in the HTML body tag  So if you can not modify the HTML file then this solution won t work for you  Step 1  add onclick attribute in the HTML body tag like this   lt body onclick  quot ok performClick this value   quot  gt       lt h1 gt This is heading 1 lt  h1 gt       lt p gt This is para 1 lt  p gt   lt  body gt   Step 2  implement addJavascriptInterface in your app to handle click listener  webView addJavascriptInterface new Object          JavascriptInterface     public void performClick String string            handler sendEmptyMessageDelayed CLICK ON WEBVIEW  0             quot ok quot     Step 3  We can not perform any action on main thread from performClick method so need to add Handler class  private final Handler handler   new Handler this      class-level variable  private static final int CLICK ON WEBVIEW   1     class-level variable   implement Handler Callback to your class and the override handleMessage  Override public boolean handleMessage Message message        if  message what    CLICK ON WEBVIEW            Toast makeText getActivity     quot WebView clicked quot   Toast LENGTH SHORT  show            return true            return false

Hamidreza s solution almost worked for me   I noticed from experimentation that a simple tap usually has 2-5 action move events   Checking the time between action down and up was simpler and behaved more like what I expected   private class CheckForClickTouchLister implements View OnTouchListener       private final static long MAX TOUCH DURATION   100        Override     public boolean onTouch View v  MotionEvent event             switch  event getAction                   case MotionEvent ACTION DOWN                  m DownTime   event getEventTime      init time                  break               case MotionEvent ACTION UP                  if event getEventTime   - m DownTime  lt   MAX TOUCH DURATION                        On click action                  break               default                  break    No-Op                    return false
