在Android中左右对齐两个按钮的布局 [英] Align two-button layout left and right in Android

问题描述

我要对齐两个具有线性布局的按钮，一个在左侧，一个在右侧，就像图库中的下一个和上一个按钮一样.我试图将它们对齐，但不起作用.

I want to align two buttons with a linear layout, one on the left, and one on the right, like the next and previous buttons on an image gallery. I tried to align them but it doesn't work.

XML布局代码:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="@android:color/white"
    android:gravity="bottom" >


    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/black" >

        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="prev"
            android:layout_alignParentRight="true" />

        <Button
            android:id="@+id/button2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="next" />

    </LinearLayout>

</LinearLayout>

实际输出:

预期输出:

我该如何解决?

推荐答案

使用RelativeLayout.在这里可以设置android:layout_alignParentLeft和android:layout_alignParentRight. 这应该为您工作:

Use a RelativeLayout. There you can set android:layout_alignParentLeft and android:layout_alignParentRight. This should work for you:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="@android:color/white"
    android:gravity="bottom" >


    <RelativeLayout
        android:id="@+id/relativeLayout1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/black" >

        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="prev"
            android:layout_alignParentLeft="true" />

        <Button
            android:id="@+id/button2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="next"
            android:layout_alignParentRight="true"/>

    </RelativeLayout>

</LinearLayout>
