我目前正在开发一个移动应用程序,但在尝试将页脚放在 ScrollView 下时遇到了问题。
这是我的代码:
<RelativeLayout
android:id="@+id/RelativeLayout01"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/bottomcontent"
android:orientation="vertical"
android:background="@drawable/border">
//the footer is added dynamically
</RelativeLayout>
<ScrollView
android:layout_weight="1"
android:id="@+id/scroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="@+id/contentcontainer">
<LinearLayout
android:id="@+id/scrollcontentcontainer"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
//the content is added dynamically from a layout template
</LinearLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>
scrollview的内容是一组相对布局,里面有一些buttons和textviews。它基于我多次膨胀的布局。
页脚只是一个带有一些按钮的线性布局。
问题是我尝试了我在 Internet 上找到的所有不同解决方案,但没有一个有效。在我的例子中,页脚卡在 ScrollView 的内容下面,而不是 ScrollView 本身下面,所以我必须向下滚动直到内容结束才能到达我的页脚。但是页脚应该保留在屏幕底部......
我也尝试了这些解决方案,但没有任何效果: - http://www.javacodegeeks.com/2013/10/android-fixed-header-and-footer-with-scrollable-content-layout-example.html (当我尝试这个时,我在屏幕顶部有一个页脚,没有别的......) - http://www.byteslounge.com/tutorials/android-fixed-header-and-footer-with-scrollable-content-layout-example 和其他一些(效果不佳!)
我也尝试了所有可能的事情,比如使用重力、重量、fillViewPort、对齐底部……但不可能得到预期的结果。 最小API设置为14,我用的是android studio。
谢谢大家的帮助!
编辑1: 边框可绘制 `在这里输入代码
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:bottom="-2dp"
android:left="-2dp"
android:right="-2dp"
android:top="2dp">
<shape android:shape="rectangle" >
<stroke
android:width="1dp"
android:color="#000000" />
<solid android:color="#3b010101" />
<padding android:left="10dp"
android:right="10dp"
android:top="10dp"
android:bottom="10dp" />
</shape>
</item>
</layer-list>
最佳答案
您可以尝试以下操作,我在 RelaveLayout
中添加 ScrollView
时也遇到了麻烦。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:id="@+id/bottomcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="@drawable/border">
<!---add something there eg:-->
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Test"/>
</RelativeLayout>
<ScrollView
android:id="@+id/scroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@id/bottomcontent"
android:layout_alignParentTop="true">
<LinearLayout
android:id="@+id/contentcontainer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:id="@+id/scrollcontentcontainer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>
我在 this documentation 中找到了以下内容.这肯定会导致问题
Note: In platform version 17 and lower, RelativeLayout was affected by a measurement bug that could cause child views to be measured with incorrect MeasureSpec values. (See MeasureSpec.makeMeasureSpec for more details.) This was triggered when a RelativeLayout container was placed in a scrolling container, such as a ScrollView or HorizontalScrollView. If a custom view not equipped to properly measure with the MeasureSpec mode UNSPECIFIED was placed in a RelativeLayout, this would silently work anyway as RelativeLayout would pass a very large AT_MOST MeasureSpec instead.
This behavior has been preserved for apps that set android:targetSdkVersion="17" or older in their manifest's uses-sdk tag for compatibility. Apps targeting SDK version 18 or newer will receive the correct behavior
关于android - 无法将页脚添加到 ScrollView - android,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/32302970/
