<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<include
layout="@layout/view1"
android:layout_gravity="center_vertical" />
<include
layout="@layout/view2"
android:layout_gravity="center_vertical" />
</LinearLayout>
So, android:layout_gravity will be always ignored? That’s really bad for code reusability…
It seems like layout_margin doesn’t supported either.
And here is view1.xml layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:minHeight="45dip"
android:background="@drawable/updater_background" >
<ProgressBar
style="?android:attr/progressBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginRight="7dip"
android:visibility="gone" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
Two years later, the bug still exists ! Even though ALL android:layout_* attributes should be supported by the tag, the android:layout_gravity attribute is not (which kind of is a big disadvantage for layout re-usability).
The work around that I am currently using is to set the layout margin programmatically as follows :
( (LinearLayout.LayoutParams) includedView.getLayoutParams () ).gravity = Gravity.BOTTOM | Gravity.RIGHT;
OR for a FrameLayout as parent for example :
( (FrameLayout.LayoutParams) includedView.getLayoutParams () ).gravity = Gravity.BOTTOM | Gravity.RIGHT;
EDIT :
I have also found that the android:layout_gravity attribute is applied for the include tag IF it (The include tag) has layout_width and layout_height tags !
Answer：
I think this can be solved by inserting weighted layout
For example
<LinearLayout
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.sample.SampleActivity">
<LinearLayout
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="0dp">
<--Some other Views-->
</LinearLayout>
<include
android:layout_width="match_parent"
android:layout_height="wrap_content"
layout="@layout/my_awesome_layout"
/>
The LinearLayout can be replaced with Space, if you don’t want any component.
Answer：
http://developer.android.com/resources/articles/layout-tricks-reuse.html states all the layout_ attributes are supported.
In your case centering in a horizontal LinearLayout probably has no effect. Try another layout other parameters.
