How the main window of the activity interacts with the window
containing the on-screen soft keyboard. The setting for this attribute
affects two things: The state of the soft keyboard —
whether it is hidden or visible — when the activity becomes the focus of
user attention.The adjustment made to the activity's main window —
whether it is resized smaller to make room for the soft keyboard or
whether its contents pan to make the current focus visible when part of
the window is covered by the soft keyboard. The
setting must be one of the values listed in the following table, or a
combination of one "state..." value plus one "adjust..." value. Setting
multiple values in either group — multiple "state..." values, for
example &mdash has undefined results. Individual values are
separated by a vertical bar (|). For example: <activityandroid:windowSoftInputMode="stateVisible|adjustResize" . . . >
Values set here (other than "stateUnspecified" and "adjustUnspecified") override values set in the theme.

---|
"stateUnspecified" | The
state of the soft keyboard (whether it is hidden or visible) is not
specified. The system will choose an appropriate state or rely on the
setting in the theme. This is the default setting for the behavior of the soft keyboard. | "stateUnchanged" | The soft keyboard is kept in whatever state it was last in, whether visible or hidden, when the activity comes to the fore. | "stateHidden" | The
soft keyboard is hidden when the user chooses the activity — that is,
when the user affirmatively navigates forward to the activity, rather
than backs into it because of leaving another activity. | "stateAlwaysHidden" | The soft keyboard is always hidden when the activity's main window has input focus. | "stateVisible" | The
soft keyboard is visible when that's normally appropriate (when the
user is navigating forward to the activity's main window). | "stateAlwaysVisible" | The
soft keyboard is made visible when the user chooses the activity — that
is, when the user affirmatively navigates forward to the activity,
rather than backs into it because of leaving another activity. | "adjustUnspecified" | It
is unspecified whether the activity's main window resizes to make room
for the soft keyboard, or whether the contents of the window pan to make
the currentfocus visible on-screen. The system will automatically
select one of these modes depending on whether the content of the window
has any layout views that can scroll their contents. If there is such a
view, the window will be resized, on the assumption that scrolling can
make all of the window's contents visible within a smaller area. This is the default setting for the behavior of the main window. | "adjustResize" | The activity's main window is always resized to make room for the soft keyboard on screen. | "adjustPan" | The
activity's main window is not resized to make room for the soft
keyboard. Rather, the contents of the window are automatically panned so
that the current focus is never obscured by the keyboard and users can
always see what they are typing. This is generally less desirable than
resizing, because the user may need to close the soft keyboard to get at
and interact with obscured parts of the window. | 在AndroidManifest.xml文件中的android:windowSoftInputMode属性使用 The AndroidManifest.xml File <activity android:windowSoftInputMode=["stateUnspecified", "stateUnchanged", "stateHidden", "stateAlwaysHidden", "stateVisible", "stateAlwaysVisible", "adjustUnspecified", "adjustResize", "adjustPan"] …… > </activity> attributes: android:windowSoftInputMode 活动的主窗口如何与包含屏幕上的软键盘窗口交互。这个属性的设置将会影响两件事情: 1> 软键盘的状态——是否它是隐藏或显示——当活动(Activity)成为用户关注的焦点。 2> 活动的主窗口调整——是否减少活动主窗口大小以便腾出空间放软键盘或是否当活动窗口的部分被软键盘覆盖时它的内容的当前焦点是可见的。 它
的设置必须是下面列表中的一个值,或一个”state…”值加一个”adjust…”值的组合。在任一组设置多个值——多
个”state…”values,例如&mdash有未定义的结果。各个值之间用|分开。例如: <activity
android:windowSoftInputMode="stateVisible|adjustResize" . . . > 在这设置的值(除"stateUnspecified"和"adjustUnspecified"以外)将覆盖在主题中设置的值 值 描述 "stateUnspecified" 软键盘的状态(是否它是隐藏或可见)没有被指定。系统将选择一个合适的状态或依赖于主题的设置。这个是为了软件盘行为默认的设置。 "stateUnchanged" 软键盘被保持无论它上次是什么状态,是否可见或隐藏,当主窗口出现在前面时。 "stateHidden" 当用户选择该Activity时,软键盘被隐藏——也就是,当用户确定导航到该Activity时,而不是返回到它由于离开另一个Activity。 "stateAlwaysHidden" 软键盘总是被隐藏的,当该Activity主窗口获取焦点时。 "stateVisible" 软键盘是可见的,当那个是正常合适的时(当用户导航到Activity主窗口时)。 "stateAlwaysVisible" 当用户选择这个Activity时,软键盘是可见的——也就是,也就是,当用户确定导航到该Activity时,而不是返回到它由于离开另一个Activity。 "adjustUnspecified"
它不被指定是否该Activity主窗口调整大小以便留出软键盘的空间,或是否窗口上的内容得到屏幕上当前的焦点是可见的。系统将自动选择这些模式中一种
主要依赖于是否窗口的内容有任何布局视图能够滚动他们的内容。如果有这样的一个视图,这个窗口将调整大小,这样的假设可以使滚动窗口的内容在一个较小的区
域中可见的。这个是主窗口默认的行为设置。 "adjustResize" 该Activity主窗口总是被调整屏幕的大小以便留出软键盘的空间。 "adjustPan"
该Activity主窗口并不调整屏幕的大小以便留出软键盘的空间。相反,当前窗口的内容将自动移动以便当前焦点从不被键盘覆盖和用户能总是看到输入内容
的部分。这个通常是不期望比调整大小,因为用户可能关闭软键盘以便获得与被覆盖内容的交互操作。
