The old Android Studio used to create the layout files using RelativeLayout, but the new one use ConstraintLayout, and this let me very pissed off >:[ , cause it have to import and sync... I really do not like.
I do not used to use both (RelativeLayout or ConstraintLayout), I prefer LinearLayout vertical, but I did not find how I can change the layout template in order to Android Studio create a layout using LinearLayout vertical, Anyone knows?
I looked for in Preferences -> File and Code Templates however I didn't find where I can change the xml layout template...
Thx
I'm not sure if you can do that, so just replace relative with linear in the xml & don't forget to add to add the orientation
Just delete the content in the layout file, and use the linear layout in that file

My project contains a number of custom layouts that (mostly) extend ConstraintLayout
I use xmls like this:
<merge xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
......
to create the views and then I inflate them in my code
The problem is that I can't really see the changes I make to the view unless I change the merge tag with ConstraintLayout
Is there a tools parameter that could help me in this, so that they would at least show correctly in the designer?
Adding tools:parentTag attribute to your merge tag with appropriate value should allow you to see the layout in the Preview window. Depending on which library you use it should be either
tools:parentTag="androidx.constraintlayout.widget.ConstraintLayout"
or
tools:parentTag="android.support.constraint.ConstraintLayout"
To be able to use the tools namespace you also need to add
xmlns:tools="http://schemas.android.com/tools"
to your merge tag.
I start more or less the development of android. I needed to create different layouts celon the android versions but now I would like to move a button. How to move this button on all the corresponding layouts whatever version of android at one time?
If there is already a post on it, sorry but I have not found it.
It's for the same screen size of course
Example: I have a linear layout of which I want to modify the right margin and I want this to do on the linear layout for versions <21 AND >21 by only doing it once and not two
Thanks !
If you have two layout files:
res/layout-v11/layout.xml AND
res/layout/layout.xml
You'll need to change the margin values in both files if they are hard coded.
Otherwise, you can have:
<LinearLayout
...
android:layout_marginEnd="#dimen/left_margin" >
and in res/values/dimens.xml have
<dimen name="left_margin">16dp</dimen>
and just change the value once in the dimens.xml file.
I usually use Relative layout for most of my activity. I want to make Android studio create Relative layout by default when I create new activity, instead of Constraint Layout. Is there a way to do that?
Right click on layout folder -> New -> Edit File Templates...
A dialog opened, go to "Other" tab.
Change the content of
"LayoutResourceFile.xml" and "LayoutResourceFile_vertical.xml"
Change root tag to the type of layout you want. Hope this help :)
goto
'...\Android\Android Studio\plugins\android\lib\templates\activities\common\root\res\layout\simple.xml'
and change default layout
I a created a linearlyaout and added views to it using java code. is it possible to convert this layout to xml layout and save it to the storage ?
There is nothing stopping you from parsing all those Views attributes and then building a xml layout file. However you will not be able to use that constructed xml layout(like setContentView(R.layout.built_layout)) like other layouts from the res/layout folder.
Im creating a custom layout and I want to use the text declared in the layout.xml file in my layout.
Like when I create a TextView in XML and set android:text=#string/text1 when I run the app text view automatically loads the text from android:text. So how can I access attributes declared in the layout XML file in my custom component.
I have learn how to do it from this:
WebImageView: Buy one, get two!
In simple steps:
Define the string of your XMLS.
Get the attributes in the code.
