I used percent relative layout in my project. It working good under android 7.
But I tested with nougat. Its not working.
Waiting Your Helps.
As documentation says, after Oreo(maybe you are using the 26 SDK?) it's deprecated, you will need to use ConstraintLayout

Hope this helps

I just started my first Android Studio project and I already come with a problem :)
I search on google for the answer but didn't find my problem.
So I need your help please ^^
I download the last version of Android Studio, create a project with an Empty Activity and I came up with this
As you can see my ConstraintLayout is really small and I just can't work with this.
I didn't touch anything on the project. Just to be sure I create 3 projects that have the same issue and redownload 4 time Android Studio.
On the virtual Devices, it looks correct throw: Screenshot
I put the XML code just in case it can help
xmlcode
Hope I was clear and sorry for my English ;)
EDIT: For some reason, the constraint layout fit correctly on the watch screen, but I don't want to create a watch app x) screenshot_watchview
Ok so I have finally find the problem ! I'm so happy right now :D
The problem was the AppTheme theme that I use, I switch it with the DeviceDefault theme. I don't know why this theme was causing problem but now it work and I can finally work on my first Android App !
If you are using the supportLibrary 28+ then this thing happened to me too.
and when I change the support lib version to the 27, it works.
Maybe this is a possible bug in the support library 28+.
Changing the AppTheme works like a charm if you want to stick with the support library 28+ But if you still don't want to so Try using the support library below 28.
I have a RelativeLayout and I am using android:layout_marginEnd="170dp"
and Android Studio is telling me:
To support older version than API 17(project specifies 15) you should
also add
android:layout_marginRight="170dp"
It's not an error, it compiles correctly, but I don't understand this hint. Why should I use marginRight? Why not marginLeft?
Can anyone explain me the secret behind this?
I looked for other answers but I still didn't get it.
Thank you in advance.
android:layout_marginEnd was added in API 17 for better support for right-to-left languages. However, earlier versions of Android prior to API 17 don't recognize this tag, so your need to add android:layout_marginRight as well.
recently I started working with android toolbars.
I am testing on android version 4.4.4 and 5.1.1. I am facing that the toolbars height are different. I have been trying hard to find an answer with no luck. I can provide source code, if you need.
Thanks in advance and Happy Holidays!
I already recreated the project from scratch, so I can not provide source code. Maybe I forgot to add android:fitsSystemWindows="true" in my layout.xml.
I just downloaded Android Studio May 10, 2014 and started using the rich layout editor.
I noticed that when I would drag and drop a RelativeLayout, Android Studio would automatically use fill_parent for both the layout_width and the layout_height attributes.
Why does Android Studio not fill in the non-deprecated value, match_parent by default?
It has been filed as a bug but has not yet been confirmed. You can see the bug report here.
Because it's in alpha stage of development :)
I'm almost done with my app, and, i admit i made a mistake. I set the min build target a 2.3.1 at the begining and now, i want to downgrade it to 2.1 at least. Everything looks fine except in xml files. i got this :
error: Error: String types not allowed (at 'layout_width' with value 'match_parent').
My question is quite simple : anyone know how can i fix that ? I don't think minSDK 7 refuses the "match parent", but maybe i'm wrong.
Thanks in advance ;)
Change match_parent to fill_parent.
Try to use fill_parent instead of match_parent.Hope this will work for you.match_parent is replaced by fill_parent for some higher version(Exact version from which it is deprecated I don't know).
I tried in sdk 2.1 and match_parent is not working but in Google API 2.1 sdk match_parent is working so you can change the sdk version to Google API 2.1 and then test if it is working in real device if yes then match_parent will works fine otherwise change the match_parent to fill_parent
hope it will help!!
