Capture event on Android after some seconds


I want to add a button to my app in Android and capture the event on this button (onclick) after a couple of seconds pushing the button, so it doesn't react at the first touch. Is this possible to achieve on Android?

Right now I have the next code that captures an onclick on the home button (in the ActionBar).

public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == android.R.id.home) {
        showSendLogAlert();
    }

    return super.onOptionsItemSelected(item);
}

When an user clicks on this button, it sends a little report by email, and I don't want to launch this event accidentally, that's why I want the user to push a couple of seconds in order to be sure he wants to do that operation.

Solution:

Based on the comments below I got this working solution:

@Override
protected void onCreate(final Bundle savedInstanceState) {
    // stuff

    // Set the home button clickable
    getActionBar().setHomeButtonEnabled(true);

    // Define a long click listener instead of normal one
    View homeButton = findViewById(android.R.id.home);
    homeButton.setOnLongClickListener(new View.OnLongClickListener() {

        @Override
        public boolean onLongClick(View v) {
            showSendLogAlert();
            return false;
        }
    });

    // more stuff
}

Solution

  • I've made something similar, but in my case I wanted to show a new activity if the button was pressed continuously for 3 seconds. Use this code for reference.

    Runnable mRunnable,timeRunnable;
    Handler mHandler=new Handler();
    
    btnBackoffice = (Button) findViewById(R.id.btn_backoffice);
    
    btnBackoffice.setOnTouchListener(buttonOnTouchListener);    
    
    private OnTouchListener buttonOnTouchListener = new OnTouchListener() { 
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch ( event.getAction() ) {
            case MotionEvent.ACTION_DOWN:
                mHandler.postDelayed(timeRunnable, 3000);
                break;
            case MotionEvent.ACTION_UP:
                 mHandler.removeCallbacks(timeRunnable);
                break;
            }
            return true;
        }
    };
    
    timeRunnable=new Runnable(){
            @Override
            public void run() {
                Intent intent = new Intent(MainActivity.this, BackofficeActivity.class);
                startActivity(intent);
    
            }
        };
    

    Hope it helps.
