Question

我不确定如何正确对齐图像视图;带有“选择处理”按钮文本的箭头图像。我试图设置imageview的边距，但它似乎没有解决问题。任何人都可以帮忙吗？

以下是布局图像和代码的屏幕截图。

Answer 1

将您的request_TreatmentLayout 方向 android:orientation="vertical" 更改为 android:orientation="horizontal" ，就像这样

    <LinearLayout
    android:id="@+id/request_TreatmentLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="35dp"
    android:layout_marginLeft="50dp"
    android:layout_marginRight="50dp"
    android:orientation="horizontal"
    android:layout_below="@id/request_SessionLayout">

    <Button
        android:id="@+id/request_TreatmentsBtn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/request_SessionLayout"
        android:layout_weight="1"
        android:textColor="@color/dark_blue"
        android:text="@string/select_treatments"
        android:textAllCaps="false"
        android:background="@color/transparent" />

    <ImageView
        android:id="@+id/appt_ArrowImage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_like"
        android:layout_gravity="right"
        android:layout_alignParentRight="true"
        android:layout_marginRight="30dp"
        android:scaleX="0.75"
        android:scaleY="0.75" />
</LinearLayout>

尝试代码：

<RelativeLayout
                    android:id="@+id/request_TreatmentLayout"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginTop="35dp"
                    android:layout_marginLeft="50dp"
                    android:layout_marginRight="50dp"
                    android:orientation="vertical"
                    android:layout_below="@id/request_SessionLayout">

                <Button
                        android:id="@+id/request_TreatmentsBtn"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:layout_weight="1"
                        android:textColor="@color/dark_blue"
                        android:text="@string/select_treatments"
                        android:textAllCaps="false"
                        android:background="@color/transparent"/>

                <ImageView
                        android:id="@+id/appt_ArrowImage"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:src="@drawable/ic_arrow"
                        android:layout_gravity="right"
                        android:layout_alignParentRight="true"
                        android:layout_marginRight="15dp"
                        android:layout_below="@id/request_TreatmentsBtn"
                        android:scaleX="0.75"
                        android:scaleY="0.75"/>
            </RelativeLayout>
