Question

I have the following code that starts an activity after detecting an onTap event.

Trouble is that more often than not it detects 2-3 taps from one user just pressing and so starts multiple. Is there any way to dampen the effect and only open the once?

protected boolean onTap(int i) {

            Log.i("TAP","CALLED");


            myOverlayItem item =getItem(i);

            if (selectedName.equals(item.getTitle())){


                try{    
                Intent myIntent = new Intent(AppMain.this, DetailActivity.class);
                myIntent.putExtra( "int", i);
                myIntent.putExtra( "string", selectedName );
                AppMain.this.startActivity(myIntent);
                }catch (Exception e){
                    Log.e("Error", "Cannot launch", e);
                }
            }
}

Thanks!

Try setting a boolean to true so you can make sure the code only runs once

boolean activityIsAlreadyRunning;


if(activityIsAlreadyRunning == false){
    if (selectedName.equals(item.getTitle())){
        try{    
            Intent myIntent = new Intent(AppMain.this, DetailActivity.class);
            myIntent.putExtra( "int", i);
            myIntent.putExtra( "string", selectedName );
            AppMain.this.startActivity(myIntent);

            activityIsAlreadyRunning = true;

            }catch (Exception e){
                Log.e("Error", "Cannot launch", e);
            }
    }
}
