我对layout_through.axml的xml视图如下:
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:id="@+id/linear_2"

android:paddingBottom="@dimen/PortscustomviewresultsTextViewPaddingTopBottom" />
<LinearLayout
android:id="@+id/linear_3"
android:orientation="vertical"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:weightSum="2"

android:textSize="@dimen/PortscustomviewresultsTextViewtextsizeCommon"
android:textColor="@color/BlackText" />
</LinearLayout>
</LinearLayout>
<ListView
android:id="@+id/loopbackThroughListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@id/linear_2"
android:divider="#0188dd00"
android:dividerHeight="0dp"

android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@id/loopbackThroughListView"
android:background="@drawable/dual_list_view_footer_next">
<TextView
android:id="@+id/oneOfThreeTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"

android:textStyle="bold"
android:textSize="@dimen/PortscustomviewresultsTextViewtextsizeCommon"
android:textColor="@color/WhiteText"
android:paddingBottom="@dimen/PortscustomviewoneOfThreePaddingTopBottom"
android:paddingTop="@dimen/PortscustomviewoneOfThreePaddingTopBottom" />
<TextView
android:id="@+id/nextTextView"
android:layout_width="wrap_content"

android:layout_alignTop="@id/oneOfThreeTextView"
android:layout_marginRight="@dimen/PortscustomviewnextImageViewmarginright"
android:layout_marginTop="@dimen/PortscustomviewnextImageViewmargintop" />
</RelativeLayout>
由于此布局通过LoopbackThroughCustomView.cs类膨胀,因此父级具有xml以下:
<Samsung.Ethernet.AndroidDevice.LoopbackThroughCustomView
android:id="@+id/loopbackCustomView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:paddingLeft="@dimen/PortsloopbackCustomViewmarginleft"
android:paddingRight="@dimen/PortsloopbackCustomViewmarginright"
android:layout_below="@id/loopbackplainTxtView" />
LoopbackThroughCustomView.cs类中的膨胀代码如下: -
Inflate(Context, Resource.Layout.loopback_through, this);
适配器列表视图中的膨胀代码如下:
if (view == null)
{
holder = new LoopbackThroughViewHolder();
view = _activity.LayoutInflater.Inflate(Resource.Layout.loopback_through_listitem, parent, false);
holder.result = view.FindViewById<TextView>(Resource.Id.resultTextView);
holder.numberofframe = view.FindViewById<TextView>(Resource.Id.numberofframeTextView);
holder.wrightWrong = view.FindViewById<ImageView>(Resource.Id.tickCrossImageView);
holder.linear1 = view.FindViewById<RelativeLayout>(Resource.Id.linearLayout1);
view.Tag = holder;
}
listitem的loopback_through_listitem.axml布局如下:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/loopback_through_listview_background">
<View
android:id="@+id/lineMiddleTextView"
android:layout_width="@dimen/Portscustomviewlinewidth"
android:layout_height="@dimen/PortslistitemlineMiddleTextViewheight"
android:layout_centerInParent="true"
android:background="@color/EasyGUIBtnStartColor" />
<TextView
android:id="@+id/resultTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_toLeftOf="@id/lineMiddleTextView"
android:layout_marginRight="@dimen/PortslistitemresultTextViewMarginRight"
android:textSize="@dimen/PortsEasyGUIBtnTextSize"
android:textColor="@color/BlackText" />
<TextView
android:id="@+id/numberofframeTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_toRightOf="@id/lineMiddleTextView"
android:layout_marginLeft="@dimen/PortslistitemresultTextViewMarginRight"
android:textSize="@dimen/PortsEasyGUIBtnTextSize"
android:textColor="@color/BlackText" />
<ImageView
android:id="@+id/tickCrossImageView"
android:src="@drawable/green_check"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_alignParentRight="true"
android:layout_marginRight="@dimen/PortslistitemresultTextViewMarginRight" />
现在的问题是,当我将分频器高度赋予&#34; 0dp&#34;在loopback_through.axml的listview中,然后出现listview底部的一个小额外空间(betwn listview和相对布局),当我给分隔符高度为&#34; 1dp&#34;列表视图内容占据底部空间,没有看到空间,这是我需要的解决方案。我想知道为什么在listview中看到这种类型的行为是通过保持相对布局在listview下面给分隔高度为0dp有任何其他方式来占用底部空间,我尝试给相对布局提供负marginTop但这对所有人来说都不是完美的装置。
我想通过将分隔符高度保持为0dp并将相对布局保持为layout_below listview而不给出任何上边距或下边距来消除listview中的额外底部空间。三江源。
答案 0 :(得分:0)
在xml代码中添加以下行:
android:footerDividersEnabled="false"
它将删除列表视图中显示为空格的最后一个页脚分隔符。
快乐编码!!!
