more preferred solution is   onclick      btn setEnabled false     btn setClickable false       yourwork   myWork       myWork       your tasks   btn setEnabled true    btn setClickable true       As a link can be ignored easily  I had to repeat this again and again

User · Answer

Setting the button as clickable false upon clicking and true once it is desired to make the button clickable again is the right approach   For instance  consider the following scenario  you are making a service call upon click of a button and once the service is done you want to display a dialog  For this  once the button is clicked you can set setClickable false  and once the service responds you will do setClicklable true  through a reference you pass to your custom dialog  When dialog invokes isShowing   you can trigger the listener and setClicklable true

I needed that woking with fragments and just put a flag to controll the clicks  I only want the first one  the others can t access to the listener  private boolean flag   true         Override public void onClick View view                  if  flag                          listener onFragmentInteraction Constants MY FRAGMENT  bundle           flag   false                      Hope it will useful  and correct me if it is not correct

setEnabled false  works perfectly for me   The idea is I write   setEnabled true     in the beginning and just make it false on the first click of the button

I found none of these suggestions works if the onClick method doesn t return immediately  The touch event is queued by Android and the next onClick is called only after the first one is finished   Since this is done on the one UI thread this is really normal   I needed to use the time when the the onClick function is finished   one boolean variable to mark whether the given onClick is running  Both these marker attributes are static to avoid any onClickListener to run at the same time   If user clicks on another button  You can simple replace your OnClickListener to this class and instead of implementing the onClick method you need to implement the abstract oneClick   method       abstract public class OneClickListener implements OnClickListener        private static boolean started   false      private static long lastClickEndTime   0           non-Javadoc          see android view View OnClickListener onClick android view View               Override     final public void onClick final View v            if started    SystemClock elapsedRealtime  -lastClickEndTime  lt 1000                Log d OneClickListener class toString     Rejected double click      new Date   toString                  return                     Log d OneClickListener class toString     One click  start      new Date   toString              try              started   true              oneClick v            finally              started   false              lastClickEndTime   SystemClock elapsedRealtime                Log d OneClickListener class toString     One click  end      new Date   toString                           abstract protected void oneClick View v

in my situation i was using a button view and it was taking the clicks too quickly  just disable the clickable and enable it again after a few seconds     Basically i made a wrapper class that wraps around your Views onClickListener  you can also set a custom delay if you want   public class OnClickRateLimitedDecoratedListener implements View OnClickListener        private final static int CLICK DELAY DEFAULT   300      private View OnClickListener onClickListener      private int mClickDelay            public OnClickRateLimitedDecoratedListener View OnClickListener onClickListener                this onClickListener  CLICK DELAY DEFAULT                        customize your own delay         public OnClickRateLimitedDecoratedListener View OnClickListener onClickListener  int delay                this onClickListener   onClickListener              mClickDelay   delay                      Override         public void onClick final View v                v setClickable false               onClickListener onClick v                v postDelayed new Runnable                      Override                 public void run                         v setClickable true                                    mClickDelay                     and to call it simply do this   mMyButton setOnClickListener new OnClickRateLimitedDecoratedListener new View OnClickListener                   Override              public void onClick View v                     doSomething                                   or provide your own delay    mMyButton setOnClickListener new OnClickRateLimitedDecoratedListener new View OnClickListener                           Override                      public void onClick View v                             doSomething                                              1000      UPDATE  Above ways a little old fashion now that RxJava is so prevalent  as others have mentioned  in android we could use a throttle to slow down the clicks  here is one example    RxView clicks myButton                       throttleFirst 2000  TimeUnit MILLISECONDS  AndroidSchedulers mainThread                         subscribe                           Log d  i got delayed clicked                                     you can use this library for it   implementation  com jakewharton rxbinding2 rxbinding 2 0 0

Setting Clickable to false does not work on the first double click but subsequent double clicks are blocked   It is as though the loading click delegate the first time is slower and the second click is captured before the first completes             Button button   contentView FindViewById lt Button gt  Resource Id buttonIssue           button Clickable   false          IssueSelectedItems            button Clickable   true

The Best and simple solution i found is  1  to create a boolean and set as false  default  like private boolean itemClicked   false      for a safer side you can also declare boolean false in onCreate   also     and at onclick   method check  2  if  itemClicked    itemClicked   true     rest of your coding functionality goes here of onClick method    3  last step is to set boolean false in onResume    override onResume     super onResume 0   itemClicked   false

If the only thing the button do is launching a new activity the problem could be solved with  singleTop  activiy launch mode and FLAG ACTIVITY CLEAR TOP being set on the intent  This one will not work in the case of complex activity s ierarchy but sutable for simple tree-like application structure

If you don t want  or can not  use boolean flags or override onClickListener  you also can try to declare your activity with android launchMode  quot singleTop quot  in AndroidManifest xml  How it s work   If an instance of the activity is at the top of the stack     new activity will not be create  instead     onNewIntent   will be called  Activity can have multiple instances Instances can reside in different tasks One task can have multiple instances

If someone is still looking for a short answer you can use the below code   private static long mLastClickTime   0    if  SystemClock elapsedRealtime   - mLastClickTime  lt  1000       1000   1second          return         mLastClickTime   SystemClock elapsedRealtime      This code will go inside the if statement whenever the user clicks on the View within 1 second and then the return  will be initiated and the further code will not initiate

The actual solution to this problem is to use setEnabled false  which greys out the button  and setClickable false  which makes it so the second click can not be received I have tested this and it seem to be very effective

Disabling the button or setting unclickable is not enough if you are doing computationally intensive work in onClick   since click events can get queued up before the button can be disabled  I wrote an abstract base class that implements OnClickListener that you can override instead  that fixes this problem by ignoring any queued up clicks           This class allows a single click and prevents multiple clicks on    the same button in rapid succession  Setting unclickable is not enough    because click events may still be queued up         Override onOneClick   to handle single clicks  Call reset   when you want to    accept another click      public abstract class OnOneOffClickListener implements OnClickListener       private boolean clickable   true                  Override onOneClick   instead               Override     public final void onClick View v            if  clickable                clickable   false              onOneClick v                 reset       uncomment this line to reset automatically                                 Override this function to handle clicks         reset   must be called after each click for this function to be called        again          param v             public abstract void onOneClick View v                   Allows another click              public void reset             clickable   true            Usage is same as OnClickListener but override OnOneClick   instead   OnOneOffClickListener clickListener   new OnOneOffClickListener          Override     public void onOneClick View v                Do stuff          this reset       or you can reset somewhere else with clickListener reset             myButton setOnClickListener clickListener

This solution is quick and neat   basically you just prevent double touch from the base styles in your app and implement standard on click listener  This works like a charm with touches at the same time of different views     lt style name  AppTheme  parent  Theme AppCompat NoActionBar  gt       lt item name  android splitMotionEvents  gt false lt  item gt   lt item name  android windowEnableSplitTouch  gt false lt  item gt   lt  style gt    If your app uses some kind of gesture event this is not the right answer
