Question

我想将ImageView对齐到它的父布局的右侧（End），这是强制性的LinearLayout。也不建议在任何地方使用RelativeLayout。如下图所示，突出显示的图像应位于屏幕的右侧。并且不使用RelativeLayout。在此先感谢。

Answer 1

假设您在水平布局中有三个视图（ImageView，TextView，ImageView），您可以使用以下代码：

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/arrow"/>
        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:text="prova"
            android:textSize="30sp"
            android:layout_weight="1"/>
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/three_dots"/>
</LinearLayout>

Answer 2

您可以在LinearLayout中的ImageView之前插入一个不可见的视图，它将占用所有可用空间，如下所示：

<View
     android:layout_width="0dp"
     android:layout_height="1dp"
     android:layout_weight="1"/>

您可以像以下一样使用它：

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0.5"
        android:gravity="center_vertical"
        android:orientation="horizontal" >

        <ImageView
            android:id="@+id/img_back"

Answer 5

尝试这种方式并根据需要进行更改。更改layout_weight，直到找不到您想要的内容。我希望这会对你有所帮助。

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/img_back"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="0.5"
        android:contentDescription="@string/img_back_description"
        android:src="@drawable/back_icon" />

    <TextView
        android:id="@+id/txt_app_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="@string/txt_app_name" />

    <ImageView
        android:id="@+id/img_menu"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="0.5"
        android:contentDescription="@string/img_menu_description"
        android:src="@drawable/menu_icon" />
</LinearLayout>
