只是一个快速的愚蠢的问题。如果你看一下附带的图像。我需要我的按钮进行右对齐，但由于某种原因，它不工作重心：正确......

Just a quick stupid question. If you look at the attached image. I need my button to be right aligned but for some reason it's not working with 'gravity:right'...

下面是我的$ C $下的布局：

Here's my code for that layout:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_marginTop="35dp">

    <TextView
        android:id="@+id/lblExpenseCancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/cancel"
        android:textColor="#404040"
        android:layout_marginLeft="10dp"
        android:textSize="20sp"
        android:layout_marginTop="9dp" />

    <Button
        android:id="@+id/btnAddExpense"
        android:layout_width="wrap_content"
        android:layout_height="45dp"
        android:background="@drawable/stitch_button"
        android:layout_marginLeft="10dp"
        android:text="@string/add"
        android:layout_gravity="right"
        android:layout_marginRight="15dp" />

</LinearLayout>

为什么没有工作？感谢球员...

推荐答案

使用以下code为

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="35dp"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/lblExpenseCancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="9dp"
        android:text="@string/cancel"
        android:textColor="#404040"
        android:textSize="20sp" />

    <Button
        android:id="@+id/btnAddExpense"
        android:layout_width="wrap_content"
        android:layout_height="45dp"
        android:layout_alignParentRight="true"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="15dp"
        android:background="@drawable/stitch_button"
        android:text="@string/add" />

</RelativeLayout>
