我希望当用户点击自定义tableview的某一行时,在parrent布局的右上角位置显示两个浮动按钮,但是在布局中显示一半,在布局外显示一半。

以下是示例:

考虑到底部布局在我的表格视图行中,

这是我想添加fab的布局:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainAddEditIcons"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="visible">

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:orientation="vertical">

    <LinearLayout
        android:id="@+id/tvLAyout"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:orientation="vertical">

        <TextView
            android:id="@+id/tvRow"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:padding="10dp"
            android:paddingLeft="20dp"
            android:textColor="@color/black" />
    </LinearLayout>

</LinearLayout>
