Align two-button layout left and right in Android
提问by Dinesh
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.
我想将两个按钮与线性布局对齐,一个在左侧,一个在右侧,就像图片库中的下一个和上一个按钮一样。我试图对齐它们,但它不起作用。
XML layout code:

Use a RelativeLayout
. There you can set android:layout_alignParentLeft
and android:layout_alignParentRight
.
This should work for you:
使用一个RelativeLayout
. 在那里你可以设置android:layout_alignParentLeft
和android:layout_alignParentRight
。这应该适合你:
<?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>

With Linear Layout
使用线性布局
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev"/>
</LinearLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"/>
</LinearLayout>
With Relative Layout
使用相对布局
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev"
android:layout_alignParentLeft="true"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:layout_alignParentRight="true"/>
</RelativeLayout>

Use Relative layout in your LinearLayout

在您的LinearLayout
; 中使用相对布局
Also add android:layout_alignParentLeft="true"
to "prev" Button
也添加 android:layout_alignParentLeft="true"
到“prev”Button
and android:layout_alignParentRight="true"
to "next" Button
并android:layout_alignParentRight="true"
“下一步”Button

Something like this:
像这样的东西:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="right" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Button" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="@+id/button1"
android:orientation="vertical" >
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>
The idea is, to create a RelativeLayout as container and put first Button and then stick it to the right of parent view. After that, add Another button insideLinearLayout and set this LinearLayout into the left of first Button.
这个想法是,创建一个RelativeLayout作为容器并放置第一个Button,然后将其粘贴到父视图的右侧。之后,在LinearLayout 中添加另一个按钮,并将这个 LinearLayout 设置到第一个 Button 的左侧。
Here's the result.
结果如下。

Use a RelativeLayout
instead of a LinearLayout
you can add the tags android:layout_alignParentRight="true"
and android:layout_alignParentLeft="true"
on each button.
使用 aRelativeLayout
代替 aLinearLayout
您可以在每个按钮上添加标签android:layout_alignParentRight="true"
和android:layout_alignParentLeft="true"
。

I guess, the simplest solution is to use View in your inner LinearLayout.
我想,最简单的解决方案是在您的内部 LinearLayout 中使用 View 。
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"/>
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1"/>
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next"/>
</LinearLayout>
