How to make UI in landscape mode

Question

I have a layout which looks perfect in portrait mode but looks worst in landscape mode, I also created different folder for landscape. Still now able to make it perfect for all screens in landscape.

Here is the xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="top|center"
android:orientation="vertical"
android:padding="5dp" >

<RelativeLayout
    android:id="@+id/RelativeLayout1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@color/gray"
    android:gravity="center" >

    <TextView
        android:id="@+id/head"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/imageView1"
        android:layout_alignParentTop="true"
        android:layout_marginBottom="10dp"
        android:layout_marginLeft="40dp"
        android:layout_marginRight="40dp"
        android:layout_marginTop="10dp"
        android:layout_toRightOf="@+id/imageView1"
        android:text="Choose Mode"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:textColor="#ffffff" />

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:src="@drawable/question_image" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"

For portrait

For Landscape

Do i need to remove the weight from those four icons, help me out :(

Answer 1

on the imageview of last 4 button add this attributes -

android:adjustViewBounds="true" 
android:scaleType="fitCenter"

Answer 2

The main problem I see is the ImageView's. First off , never use "fill_parent" values since they are deprecated, instead use "match_parent".

Then, you need to remove weight property from them aswell. That's why they try to fill the screen by stretching which makes them look out of proportion.

Use fixed dp (density pixel) size (width/height) for the images, so that they maintain a proportion, no matter the size or the display quality. You can then, use different sizes and element display for both landscape and portrait using layout and layout-land folders, both storing different layout compositions with the same name so that they get called by the android framework depending on orientation.

You have official documentation about supporting multiple screen sizes / orientation (more specifically) here.
