我想在我的listview-fragment底部的确定/取消按钮接受/取消。我认为碎片是要走的路(甚至应该支持动画)。如何添加底部按钮片段(动画)
但我无法让它工作!只显示(在代码fragmentPlaceholder)的第一个片段
的按钮的XML已经我从这篇文章的接受的答案得到:
How to create standard Borderless buttons (like in the design guidline mentioned)?
的代码是C#,但问题应该在Java中也是一样。对于片段中的XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_alignParentBottom="true">
<View
android:layout_width="match_parent"
android:layout_height="1dip"
android:layout_marginLeft="4dip"
android:layout_marginRight="4dip"
android:background="?android:attr/dividerVertical"
android:layout_alignParentTop="true"/>
<View
android:id="@+id/ViewColorPickerHelper"
android:layout_width="1dip"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_marginBottom="4dip"
android:layout_marginTop="4dip"
android:background="?android:attr/dividerVertical"
android:layout_centerHorizontal="true"/>
<Button
android:id="@+id/btnCancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_toLeftOf="@id/ViewColorPickerHelper"
android:background="?android:attr/selectableItemBackground"
android:text="Cancel"
android:layout_alignParentBottom="true"/>
<Button
android:id="@+id/BtnColorPickerOk"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="?android:attr/selectableItemBackground"
android:text="Ok"
android:layout_alignParentBottom="true"
android:layout_toRightOf="@id/ViewColorPickerHelper"/>
</RelativeLayout>
为活性的XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/fragmentPlaceholder" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/addEventReportButtonPlaceholder"
android:layout_weight="10"
android:layout_gravity="bottom" />
</LinearLayout>
<ProgressBar
android:id="@+id/addEventReportProgressBar"
android:indeterminate="true"
android:layout_width="50dp"
android:layout_height="50dp"
style="?android:attr/progressBarStyle"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
包括所述片段的代码:
var newFragment = new BottomButtonsFragment();
FragmentTransaction ft = FragmentManager.BeginTransaction();
ft.Add (Resource.Id.addEventReportButtonPlaceholder, newFragment).Commit();
哪里BottomButtonsFragment是:
public class BottomButtonsFragment : Fragment
{
public override View OnCreateView (LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View v = inflater.Inflate (Resource.Layout.BottomButtonsFragment, container, false);
return v;
}
}
