Question

I have a vertical linearlayout, it has inside two linearlayout with diferent elements, I would like to fix the first one to the top, and the second one centered, I’m trying it but doesn’t work:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/background_bg"
    >

    <LinearLayout 
        android:layout_width="fill_parent"
        android:layout_height="50dip"
        android:background="#3b5998"
    >    
         elements
    </LinearLayout>


    <LinearLayout
        android:orientation="vertical"
        android:layout_width="300dip"
        android:layout_height="300dip"
        android:background="@drawable/background_resto"
        android:gravity="center"
    >

           elements
    </LinearLayout>
    </LinearLayout

Why is it not working? Thank you in advance

Answer 1

I’d advice to choose a RelativeLayout for that purpose.

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

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@android:color/holo_blue_bright"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="50dip"
        android:layout_alignParentTop="true"
        android:background="#fff" >
    </LinearLayout>

    <LinearLayout
        android:layout_width="300dip"
        android:layout_height="300dip"
        android:layout_centerInParent="true"
        android:background="@android:color/holo_green_light"
        android:orientation="vertical" >
    </LinearLayout>
</RelativeLayout>

This will help you to set the exact “relative” position in relation to other views.
