在我的工作中，今天做了一个布局发现无法响应这是布局

这个布局就只有一个timepicker其他全部是在timepicker响应的接口中

timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
setTime2data(hourOfDay, minute);
}
});

setTime2data方法中取得时间，但是发现只有按加减的按钮的才可以监听到，网上百度很久没找到原因，今天发现在timepicker还在拥有焦点的时候是无法回调监听函数的（其实仔细想想也知道用户在不断修改的时候，是不会回调的），于是在键盘输入响应回调函数就让timepicker失去焦点即可。

记下来提醒自己
