Android XML - Unable to Prevent ImageView Overlap

I'm attempting to prevent two images from overlapping - and I though I'd be able to do so using two RelativeLayouts inside a LinearLayout - both set to wrap_content - however the two imageViews ( #+id/imageView1 - the boxart and #+id/background - the background) however they still seem to overlap.
Can someone spot what I may have done wrong in this implementation?

Screenshot:

Instead of using Relative layout use a Linear layout with orientation horizontal and then use two Linear layouts with layout_weight=1 for each ImageView. It will divide your screen into two equal parts horizontally.
For example :-
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:layout_weight="1"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical" />
<LinearLayout android:layout_weight="1"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical" />
</LinearLayout>
As per your given layout update your layout as follows:-
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/download"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/black"
android:orientation="vertical">
<LinearLayout

android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:id="#+id/rl_ListView2"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/black"
android:orientation="vertical">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<LinearLayout

android:layout_height="match_parent"
android:layout_weight="1"

android:layout_alignParentRight="true"
android:background="#drawable/background_faded"

android:paddingBottom="65dp"
android:scaleType="fitXY" />

android:layout_alignRight="#+id/saveButton"
android:gravity="center_vertical"
android:text="Movies"
android:textSize="40sp" />
</LinearLayout>
<ImageView
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="#+id/downloadbtn"
android:layout_below="#+id/downloadbtn"
android:layout_marginRight="207dp"
android:layout_marginTop="110dp" />
</LinearLayout>

With regards to your particular situation, the 2 ImageViews causing problems are placed each in a RelativeLayout, which are also placed in a RelativeLayout. Views placed in a relative layout can overlap each other. So when you added the 2 children RelativeLayouts in the parent one, exactly this happened. To make one follow the other, you can add android:layout_toRightOf="#id/id_of_the_layout_you_want_on_the_left_of_this_one" to the second child.
Also, if you are willing to change your layout a bit, you could achieve this through weight and LinearLayout (note however that this will work only if the desired combined width of the 2 children is less than what the parent is willing to offer):
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
... />
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
... />
</LinearLayout>
</LinearLayout>

unwanted horizontal spacing between my ImageViews

I'm trying to place four ImageViews in a 2x2 grid fashion, and I tried everything that I know from a tableLayout to a relativeLayout and finally a nested Layout as the following
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:id="#+id/top">
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:id="#+id/imageView"
/>
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:id="#+id/imageView2"
/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_below="#id/top"
android:id="#+id/btm">
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:id="#+id/imageView3"
/>
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:id="#+id/imageView4"
android:layout_below="#id/imageView2"
/></LinearLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/changepic"
android:id="#+id/button"
android:layout_below="#id/btm"/>
but no matter what I do, I always get this "unwanted" horizontal spacing between ImageViews in same row, which is surprisingly absent between ImageViews verticaly, as the pic.
Picture Here
what is causing this?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/LinearLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context=".MainActivity" >
<LinearLayout
android:id="#+id/top"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="horizontal" >
<ImageView
android:id="#+id/imageView"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_gravity="left"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView2"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_gravity="right"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<LinearLayout
android:id="#+id/btm"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="horizontal" >
<ImageView
android:id="#+id/imageView3"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_gravity="left"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView4"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_gravity="right"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name" />
</LinearLayout>

I'd get rid of the linear layout altogether- you don't need it, and adding extra views has bad performance issues on android. Instead make the second image android:layout_toRightOf the left one. That should also kill the space.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="150dp"
android:id="#+id/imageView"
/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="150dp"
android:layout_toRightOf="#id/imageView"
android:id="#+id/imageView2"
/>
...
In addition- are you sure your width is correct? You have it as a pair of 150dpx150dp images. Those images are not square. You may not be that wide, so the extra space is because the image only fills part of that 150dp. You probably want wrap_content for width.

How to set RelativeLayout's width same as sibling View?

So i have layout like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
<RelativeLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="horizontal">
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:src="#drawable/advantage_1" />
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="#drawable/advantage_2" />
</RelativeLayout>
<ImageView
android:id="#+id/lower_image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/line" />
</LinearLayout>
Because of aligning views inside the RelativeLayout it fills all the screen. How to set RelativeLayout's width same as lower ImageView(lower_image_view)?

Try like this. The main idea is you put your RelativeLayout and the ImageView inside another RelativeLayout. Then set android:layout_alignLeft="#+id/lower_image_view" and android:layout_alignRight="#+id/lower_image_view" of the child RelativeLayout. This will achieve the width of the ImageView. You may want to modify this to achieve your desired result, but you get the idea :)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
<RelativeLayout
android:id="#+id/parentRelativeLayout"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
<RelativeLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignLeft="#+id/lower_image_view"
android:layout_alignRight="#+id/lower_image_view"
android:orientation="horizontal">
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:src="#drawable/ic_launcher" />
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
<ImageView
android:id="#+id/lower_image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/ic_launcher" />
</RelativeLayout>
</LinearLayout>

Placing a TextView below two ImageViews and in middle - Android

Please share code to achieve the layout of the screen shown in the below link. The text should be in center of the two images and all these components can be dynamic.

Hope this works
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
/>
<ImageView
android:id="#+id/imageView2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
/>
</LinearLayout>
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:gravity="center_horizontal"
android:text="TextView" />
</LinearLayout>

An easier way to do this is
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/yourBackgroundDrawableBorder"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView2"
android:background="#drawable/yourBackgroundDrawableBorder"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/imageView1"
android:padding="xxdp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/global_menu_edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/imageView1"
android:layout_centerHorizontal="true"
android:text="Textview" />
</RelativeLayout>
You need to add the custom drawables for the shapes you desire for your views..and yes obviously this is a very generic way to do it. You obviously have to edit some properties or add some to suit your needs. The other way is to use LinearLayout and the android:layout_weight="1" property to make your imageviews similar in size.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical"
android:padding="5dp" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/ic_launcher" />
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:adjustViewBounds="true"
android:layout_marginLeft="10dp"
android:scaleType="fitXY"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:lines="3"
android:layout_marginTop="10dp"
android:text="Text" />
</LinearLayout>

5 sided dice like layout in Android

I'm currently working on an Android app and I would like to make a nice layout.
What I'm trying to achieve is the following layout:
The circles will be of equal size ofcourse. Besides that i need to be able to click them so they need to be buttons or imageviews.
What would be the best approach to achieve this kind of layout?

You could use a RelativeLayout, and say where each of the dots is supposed to be in relation to each of the others.
You could also use a LinearLayout, creating three 'rows' of buttons, the top and bottom rows containing two of the 'dots' and the middle one containing one in the center.
The layout would look something like this:
And the code would be something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/dot"
android:background="#android:color/transparent"/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/dot2"
android:background="#android:color/transparent"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/dot3"
android:background="#android:color/transparent"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/dot4"
android:background="#android:color/transparent"/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/dot5"
android:background="#android:color/transparent"/>
</LinearLayout>
</LinearLayout>

Try this..
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
>
<ImageView
android:src="#drawable/ic_launcher"
android:layout_width="90dp"
android:layout_height="90dp"
android:layout_alignParentLeft="true"
android:layout_marginLeft="10dp"
/>
<ImageView
android:src="#drawable/ic_launcher"
android:layout_width="90dp"
android:layout_height="90dp"
android:layout_alignParentRight="true"
android:layout_marginRight="10dp"
/>
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
>
<ImageView
android:src="#drawable/ic_launcher"
android:layout_width="90dp"
android:layout_height="90dp"
android:layout_centerInParent="true"
/>
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
>
<ImageView
android:src="#drawable/ic_launcher"
android:layout_width="90dp"
android:layout_height="90dp"
android:layout_alignParentLeft="true"
android:layout_marginLeft="10dp"
/>
<ImageView
android:src="#drawable/ic_launcher"
android:layout_width="90dp"
android:layout_height="90dp"
android:layout_alignParentRight="true"
android:layout_marginRight="10dp"
/>
</RelativeLayout>
</LinearLayout>

Use a nest of LinearLayout or RelativeLayout. To use the images as button, then use ImageView and indicate in the xml corresponding ID for each image so you can use it in your activity.
