android中 点击非键盘区域 隐藏键盘的方法

首先要获取键盘的Manager

 InputMethodManager manager manager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
 @Override
  public boolean onTouchEvent(MotionEvent event) {
   // TODO Auto-generated method stub
   if(event.getAction() == MotionEvent.ACTION_DOWN){
      if(getCurrentFocus()!=null && getCurrentFocus().getWindowToken()!=null){
        manager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
      }
   }
   return super.onTouchEvent(event);
  }
