我面临的问题是在listview下放置一个linearlayout,如图片链接所示:
我想要使用添加图标和文字进行布局:"添加新成员"显示在列表视图下方。我究竟做错了什么?请帮我解决问题。非常感谢你。
这是布局的xml文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<ScrollView ..
<RelativeLayout..
<LinearLayout // vertical orientation
<ListView ../>
<LinearLayout // your linear layout
layout_below="@+id/listviewid"
</LinearLayout>
</RelativeLayout>
</ScrollView>
尝试此视图层次结构。

问题是android:layout_weight="1"
上有ListView
这会使其扩展为完整版并且不会为LinearLayout
答案 2 :(得分:0)
您必须在列表视图项目中进行更改,请检查此项。
将以下行添加到Adapter get view方法中:
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
view = LayoutInflater.from(TestListActivity.this).inflate(R.layout.dummy, viewGroup,false);
LinearLayout layout = (LinearLayout)view.findViewById(R.id.add_bottom_ll);
if(i==getCount()-1){
layout.setVisibility(View.VISIBLE);
}else{
layout.setVisibility(View.GONE);
}
return view;
}
列表视图项目视图xml

尝试RelativeLayout并使用android:layout_above,如下所示:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="@+id/your_listview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@+id/your_layout_with_buttons" />
<LinearLayout
android:layout_alignParentBottom="true"
android:id="@+id/your_layout_with_buttons"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
//your buttons come here
</LinearLayout>
</RelativeLayout>

set FLASK_APP=contact.py
按钮"Add New Members"
和scrollable
设置为relative
高度,请使用ListView
作为NestedScrollView
和{ListView
的容器{1}}自定义按钮"Add New Members"
。以下是完整的XML代码:
