Android Layout left and right align in horizontal layout
提问by Joseph
I am have a ImageView and a ImageButton. I have them next to each other in a horizontal layout. I am trying to make it so that the image is left aligned on the screen, and the button is right aligned. I have tried setting gravity but it doesnt seem to make a difference. Where am I going wrong?
我有一个 ImageView 和一个 ImageButton。我让它们在水平布局中彼此相邻。我试图使图像在屏幕上左对齐，按钮右对齐。我试过设置重力，但似乎没有什么区别。我哪里错了？
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<ImageView
android:id="@+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:layout_weight="1"
android:gravity="left"
android:src="@drawable/short_logo" />
<ImageButton
android:id="@+id/terminateSeed"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="right"
android:background="@null"
android:src="@drawable/unregister_icon" />
</LinearLayout>

Use This example if you want to use LinearLayout without giving Weight
如果您想使用 LinearLayout 而不提供 Weight，请使用此示例
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity="right"
/>
</LinearLayout>

Another approach for LinearLayout, using layout_weightand gravity:
LinearLayout使用layout_weight和 的另一种方法gravity：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="BUTTON 1"/>
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="BUTTON 2" />
</LinearLayout>

Make imageviewand imagebuttonwrap_contentand set layout_gravityto left and right accordingly.
使imageview和imagebuttonwrap_content并相应地设置layout_gravity为左右。

a RelativeLayoutwould solve your problem with a snap, but if you still insist on using LinearLayout (just because we're badass and do things the hard way), you do it like this:
aRelativeLayout可以快速解决您的问题，但是如果您仍然坚持使用 LinearLayout（仅仅因为我们很坏并且做事很困难），您可以这样做：
Your parent LinearLayout is fill-parent, left-aligned, and horizontally oriented, and contains your ImageView, and another LinearLayout.
您的父 LinearLayout 是填充父级、左对齐和水平方向，并包含您的 ImageView 和另一个 LinearLayout。
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="left"
Second LinearLayout is fill-parent, right-aligned, and horizontally oriented, and contains your ImageButton.
第二个 LinearLayout 是父级填充、右对齐和水平方向，并包含您的 ImageButton。
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="right"
