Android - 在带有可滚动页脚内容的滚动视图中添加滚动视图和固定页脚

Question

我正在做一个 UI 设计，我必须设计一个完全可滚动的视图。在这个视图中，我在底部有一个视图寻呼机和一个固定的页脚，但是当用户在垂直方向滚动内容时，这个页脚也会滚动。现在这里的页脚有很长的描述，但如果不滚动，那是不可见的。在水平方向滚动时，视图寻呼机将工作并且页脚似乎固定在底部。
这是我的代码。

 <ScrollView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:fillViewport="true" >

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

            <LinearLayout
                android:id="@+id/linearLayoutFooter"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignParentBottom="true"
                android:layout_margin="12dp"
                android:orientation="vertical" >

                <LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_margin="12dp"
                    android:orientation="horizontal"
                    android:weightSum="100" >

                    <TextView
                        android:layout_width="0dp"
                        android:layout_height="wrap_content"
                        android:layout_weight="80"
                        android:text="some dummy textl and Prevention"
                        android:textSize="12dp" />

                    <ImageView
                        android:id="@+id/imageviewViewExpander"
                        android:layout_width="0dp"
                        android:layout_height="wrap_content"
                        android:layout_gravity="center_vertical|center_horizontal"
                        android:layout_weight="20"
                        android:src="@drawable/page_circle_arrow_down" />
                </LinearLayout>

                <TextView
                    android:id="@+id/textveiw"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_margin="15dp"
                    android:text="some dummy textsome dummy textsome dummy textsome dummy text\nsome dummy textsome dummy textsome dummy textsome dummy textsome dummy textsome dummy text\nsome dummy textsome dummy textsome dummy textsome dummy textsome dummy text\nsome dummy textsome dummy textsome dummy textsome dummy text" >
                </TextView>
            </LinearLayout>

            <android.support.v4.view.ViewPager
                android:id="@+id/pager"
                android:layout_width="match_parent"
                android:layout_height="fill_parent"
                android:layout_above="@id/linearLayoutFooter"
                android:layout_alignParentTop="true" >
            </android.support.v4.view.ViewPager>
        </RelativeLayout>
    </ScrollView>

这里的问题是我必须让页脚粘在底部，除非用户滚动，甚至视图寻呼机内容不可见。

我认为您可以将scrollview 放在RelativeLayout 之后和LinearLayout 之前 像这样：

 <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >
<!--here-->
<ScrollView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:fillViewport="true" >

            <LinearLayout
                android:id="@+id/linearLayoutFooter"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignParentBottom="true"
                android:layout_margin="12dp"
                android:orientation="vertical" >

                <LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_margin="12dp"
                    android:orientation="horizontal"
                    android:weightSum="100" >

                    <TextView
                        android:layout_width="0dp"
                        android:layout_height="wrap_content"
                        android:layout_weight="80"
                        android:text="Content courtesy of Centers for Disease Control and Prevention"
                        android:textSize="12dp" />

                    <ImageView
                        android:id="@+id/imageviewViewExpander"
                        android:layout_width="0dp"
                        android:layout_height="wrap_content"
                        android:layout_gravity="center_vertical|center_horizontal"
                        android:layout_weight="20"
                        android:src="@drawable/page_circle_arrow_down" />
                </LinearLayout>

                <TextView
                    android:id="@+id/textViewDiseaseControl"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_margin="15dp"
                    android:text="To help recognize a concussion, you should watch for and ask others to report the following two things among your athletes:\n\nA forceful bump, blow, or jolt to the head or body that results in rapid movement of the head.\n\nAny concussion signs or symptoms, such as a change in the athlete&apos;s behavior, thinking, or physical functioning.\n\nKeep this list of signs and symptoms on hand. Athletes who exhibit or report one or more of the signs and symptoms listed below, or simply say they just &quot;don&apos;t feel right&quot; after a bump, blow, or jolt to the head or body, may have a concussion." >
                </TextView>
            </LinearLayout>
 </ScrollView><!--here-->
            <android.support.v4.view.ViewPager
                android:id="@+id/pager"
                android:layout_width="match_parent"
                android:layout_height="fill_parent"
                android:layout_above="@id/linearLayoutFooter"
                android:layout_alignParentTop="true" >
            </android.support.v4.view.ViewPager>
        </RelativeLayout>

只为需要滚动的组件提供滚动视图。将其他内容保留在滚动视图之外。您可以使用

等属性将页脚保留在活动的底部

android:alignParentBottom="true"
