SOFT_INPUT_STATE_ALWAYS_HIDDEN隐藏软键盘

useful for hiding the soft keyboard is:

 this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

This can be used to suppress the keyboard until the user actually touched the edittext view.

这句话可以写在onCreate()里面，这样当一个EditText1获得焦点的时候，然后又点击了另一个EditText2调出软键盘，当关闭EditText2的软键盘后EditText1会有软键盘弹出来。
