How to simulate a button click using code?


Solution 1

there is a better way.


this should answer all your problems. every View inherits this function, including Button, Spinner, etc.

Just to clarify, View does not have a static performClick() method. You must call performClick() on an instance of View. For example, you can't just call


Instead, do something like:

View myView = findViewById(;

Solution 2

Just to clarify what moonlightcheese stated: To trigger a button click event through code in Android provide the following:


Solution 3

you can do it this way

private Button btn;
btn = (Button)findViewById(;

Solution 4

Just write this simple line of code :-


where button is the reference variable of Button class and defined as follows:-

private Button buttonToday ;
buttonToday = (Button) findViewById(;

That's it.

Solution 5

Android's callOnClick() (added in API 15) can sometimes be a better choice in my experience than performClick(). If a user has selection sounds enabled, then performClick() could cause the user to hear two continuous selection sounds that are somewhat layered on top of each other which can be jarring. (One selection sound for the user's first button click, and then another for the other button's OnClickListener that you're calling via code.)

    How can I trigger a button click event using code in Android? I want to trigger the button click programmatically when some other event occurs.

    Same Problem I am Facing

    public void onDateSelectedButtonClick(View v){
        /*Something  Alarm Management
        copied code from this site*/

    Button code:

        android:text="Set notification for this date" />

    there is no "View" for the back button on your phone. you need to use key listeners to get those button presses. that's a different issue altogether.

    @moon - If you want to have people notified of your comments, start them with "@" and the first few letters of the user who you want notified.... (authors of the commented on post automatically get notified, but commenters do not)

    The code shown in this answer is a little confusing. Just to clarify, View does not have a static performClick() method. You must call performClick() on an instance of View.

    is correct, because button not is a button, works, because button is a view, all layers (textview/scroll/button... ) extends view, view.performClick(), only invoke click into view,
