Problem with Scrollview Layout Android Studio

25 views Asked by At

I'm new on mobile dev, so i started with android studio XML/Java and i have a litle problem with my main page. Like i will show you, i want to put my scrollview just after my first LinearLayout which is my "header" but i don't understand how. I know my code is really bad so if you can explain me what is the biggest problem just to do that.

I tried a lot of things but as you can see it's still not working only on one format but its because of the margin-top so it's really dirty.

My code :

<?xml version="1.0" encoding="utf-8"?>

The problem is that you are not using right alignment for the scroll view and trying to cover this problem with layout_margin.You should put align for views in RelativeLayout This is the Code you can use instead of your own:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".TableDesCours">

    <LinearLayout
        android:id="@+id/linearLayout2"
        android:layout_width="match_parent"
