使用ConstraintsLayout滚动（ScrollView）整个布局，不打开操作栏，全屏和键盘

Question

当软键盘打开时，我无法滚动整个布局。以下代码在没有键盘的情况下正常工作但是当键盘打开时他无法动摇整个活动。在这里我的清单：

<activity android:name=".Add"
    android:screenOrientation="sensorPortrait"
    android:windowSoftInputMode="stateHidden"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen">
</activity>

在我的xml活动中，我没有找到ConstraintsLayout的样本：

为了重新创建项目，这里是@ drawable / background_shape的代码：

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <corners android:radius="10dip"/>
    <padding android:left="0dip" android:top="0dip" android:right="0dip" android:bottom="0dip" />
</shape>
