How to inherit fields in android xml?
I want to set some properties for the first element ImageView
and then inherit the properties in other elements.
The following don't work, but is there probably something similar?
<ImageView
android:id="@+id/myimage"
android:layout_height="100dp"
android:layout_width="100dp"/>
<ImageView
android:id="@+id/myimage2"
android:layout_height="@myimage/layout_height"
android:layout_width="@myimage/layout_width"/>

You cannot do it this way, but you have 2 options:
Option 1 : declare the value as a dimension and use it:
Declare two values for height and width in dimens.xml
, which can be found in res/values
.
<dimen name="image_width">100dp</dimen>
<dimen name="image_height">100dp</dimen>
Then use them in your xml like this:
<ImageView
android:id="@+id/myimage2"
android:layout_height="@dimen/image_height"
android:layout_width="@dimen/image_width"/>
Option 2 . Create style
linked to yours ImageView
:
The first thing to do is create a style for your views and place it in styles.xml
, which can be found in res/values
.
<style name="my_image_view_style">
<item name="android:layout_height">100dp</item>
<item name="android:layout_width">100dp</item>
</style>
Add created style
to your ImageView
:
<ImageView
android:id="@+id/myimage2"
style="@style/my_image_view_style"/>
