android对TimePickerDialog进行监听 onTimeSet会执行两次!

源码中，点击确定和取消按钮时，会出发onTimeSet；在dialog的onStop（比如dialog dismiss时）中，也调用了onTimeSet方法。
解决办法:Calendar c = Calendar.getInstance();c.add(Calendar.DAY_OF_YEAR, 1);final DatePickerDialog dateDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() { boolean fired = false; public void onDateSet(final DatePicker view, final int year, final int monthOfYear, final int dayOfMonth) {  Log.i("PEW PEW", "Double fire check");  if (fired == true) {   Log.i("PEW PEW", "Double fire occured. Silently-ish returning");  fired = false;    return;  } else {   //first time fired   fired = true;  }  //Normal date picking logic goes here }}, c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));dateDialog.show();
