Question

所以，我TextView尝试使用ImageView来填充GONE LinearLayout时留下的空格......我已尝试使用{ {1}}和RelativeLayout，但ImageView的空间不是由TextView拍摄的。

那么，我是如何让它发挥作用的呢？

代码：

<RelativeLayout
    android:orientation="horizontal"
    android:id="@+id/cabecalho"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:id="@+id/imgPrimary"
        android:visibility="gone"
        android:src="@drawable/abc_btn_rating_star_on_mtrl_alpha"
        android:tint="#ecac31"
        android:layout_gravity="center_vertical"
        android:padding="3dp" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="17dp"
        android:text="Endereço de Teste"
        android:layout_toRightOf="@+id/imgPrimary"
        android:layout_toLeftOf="@+id/btnEdit"
        android:layout_centerVertical="true"
        android:id="@+id/addrTitle"
        android:layout_weight="50"
        android:textColor="@color/black"
        android:layout_gravity="center_vertical"
        android:layout_marginLeft="5dp" />

    <ImageButton
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:id="@+id/btnEdit"
        android:layout_weight="1"
        android:layout_toLeftOf="@+id/btnDelete"
        android:src="@drawable/icon_write_location"
        android:tint="#08b8ae"
        android:scaleType="fitCenter"
        android:background="@color/white"
        android:padding="10dp" />

    <ImageButton
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:id="@+id/btnDelete"
        android:layout_weight="1"
        android:scaleType="fitXY"
        android:src="@drawable/abc_ic_clear_mtrl_alpha"
        android:tint="#d60d0d"
        android:layout_alignParentRight="true"
        android:background="@color/white"
        android:padding="7dp" />
</RelativeLayout>

请求打印：空间位于大胆＆＃34; Teste＆＃34;的右边。在白卡的顶部。

来自我的recyclerview适配器的代码：

    private List<Address> addressList;

Answer 1

尝试使用线性布局，并为每个视图的布局和权重提供权重，并将每个视图的宽度设置为0dp，但确实为每个视图提供权重。在这种情况下，如果视图消失，则其他视图将占用其空间

Answer 2

这里的诀窍实际上是不提供weightSum。

<LinearLayout
    android:weightSum=3
    ...>
    <TextView
         android:layout_width="0dp"
         android:layout_weight="1">
    <TextView
         android:layout_width="0dp"
         android:layout_weight="1">
    <TextView
         android:layout_width="0dp"
         android:layout_weight="1">

将打印三个TextView，均匀间隔为每个可用空间的1/3，无论TextViews是否为View.GONE。

<LinearLayout
    ...>
    <TextView
         android:layout_width="0dp"
         android:layout_weight="1">
    <TextView
         android:layout_width="0dp"
         android:layout_weight="1">
    <TextView
         android:layout_width="0dp"
         android:layout_weight="1">

将TextViews分隔为每个空间的1/3，直到其中一个为View.GONE，此时它将调整为每个1/2空间。

如果兄弟姐妹不在，请查看填充空间
