After several attempts, I managed to work as a Imagebutton, android tv remote.
but add button is selected, or at least do not see a difference when selected.
I tried focus. but the button is not exactly still and see if it is selected or not.
what can i do ?
Thank you.

Just add attribute android:foreground="?attr/selectableItemBackground" to your ImageView to show an effect.

I have a layout which consists of a ListView and an Image. I want to place the Image above Listview (in top left corner), but on running the app only Listview is visible and Image goes behind the Listview.
I want to show image instead of first item of the list. Any suggestions?
Below is the layout file:

Try to set an elevation value in the ImageView. For example: android:elevation="5dp". This should solve your problem. Hope it helps.
You can use headerview to add the image at the top like
listview.addHeaderView(view);// view which contains that image
Try this.
This is the preview in the designer.
But when I run the app on a device (Galaxy S4 with 5.0.1) the bottom part of the fragment gets cut off.
chat_fragment.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

android:paddingRight="#dimen/activity_horizontal_margin"

android:layout_marginBottom="48dip"
android:background="#1b184b"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="48dip"
android:layout_alignParentBottom="true"
android:padding="0dp"
android:layout_margin="0dp"
android:background="#753636"
android:orientation="horizontal">
<EditText
android:layout_width="345dp"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:hint="Send a message"
android:id="#+id/newmsg"
/>
<ImageButton
android:id="#+id/newmsgsend"
android:src="#drawable/ic_send"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:scaleType="fitEnd"
android:backgroundTintMode="multiply"
android:backgroundTint="#400202" />
</LinearLayout>
</RelativeLayout>
Is this because of something that I should handle from the layout of the fragment?
I changed youx xml code. Just little changes . Use this layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll"
android:background="#1b184b"
android:layout_alignParentTop="true"
android:layout_above="#+id/edit_linear_layout"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="48dip"
android:layout_alignParentBottom="true"
android:padding="0dp"
android:layout_margin="0dp"
android:background="#753636"
android:orientation="horizontal"
android:id="#+id/edit_linear_layout"
>
<EditText
android:layout_width="345dp"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:hint="Send a message"
android:id="#+id/newmsg"
/>
<ImageButton
android:id="#+id/newmsgsend"
android:src="#drawable/ic_send"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:scaleType="fitEnd"
android:backgroundTintMode="multiply"
android:backgroundTint="#400202" />
</LinearLayout>
</RelativeLayout>
You can add bottom margin to your bottom most item to resolve the "cut off" issue.
android:layout_marginBottom="50dp"
In your case, change your ImageButton to the following
<ImageButton
android:id="#+id/newmsgsend"
android:src="#drawable/ic_send"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:scaleType="fitEnd"
android:backgroundTintMode="multiply"
android:backgroundTint="#400202"
android:layout_marginBottom="50dp" />
I would to use a VideView as background in my layout.
So I would to have this videoView fullscreen and I need to add on this view other 'components' like TextView, EditView, ImageView...etc.
This is an example of my code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" tools:context=".Login"
android:alpha="0.9">
<VideoView
android:scrollbars="none"
android:clickable="false"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_gravity="center"
android:id="#+id/VideoView">
</VideoView>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
android:alpha="0.9">
<ImageView
android:id="#+id/imageView1"
android:layout_centerHorizontal="true"
android:layout_marginTop="15dip"
android:layout_width="130dp"
android:layout_height="100dp"
android:alpha="0.7"
android:src="#drawable/logoweb"/>
etc...
In this way I can't see the other components... only the video...
Try using FrameLayout.
FrameLayout always places things one on top of the other and always in reference to the upper lefthand corner,you can use something like this to acheive the above result
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<VideoView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/VideoView"
/>
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center"
android:alpha="0.7"
android:src="#drawable/logoweb"
/>
i would like to force gauge to be centered vertically above llInner...
i just don't seem to be able
instead of llTop using all the available space it is llInner doing it.
thank you

You should use Relative Layout as main layout like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<LinearLayout
android:id="#+id/llInner"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="bottom|right"
android:background="#00ff00"
android:gravity="bottom|right"
android:orientation="horizontal" >
<eu.sextante.speedlimit.Views.LimitView
android:id="#+id/limit"
android:layout_width="wrap_content"
android:layout_height="60dip"
android:background="#0000ff"
android:maxHeight="60dip"
android:maxWidth="60dip" />
</LinearLayout>
<your.gaugeview
android:id="#+id/gauge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:text="dfdg" />
</RelativeLayout>
Hope it helps you.
I'm relatively new to Android development and I'm having a hard time putting together a certain interface. I've looked through many similar questions but none of them give me the answer i'm looking for.
I want to put together an XML interface like the following:
I want a LinearLayout that acts like a sticky footer that will contain two Buttons. This part will always align to the bottom and and will always be 60dp high. The RelativeLayout would then be on top of the footer, but it's height should scale depending on the screen size.
I've tried the following:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".DartboardActivity">
<RelativeLayout
android:id="#+id/game_layout"
android:layout_width="match_parent"
android:layout_height="506dp"
android:background="#drawable/background"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<ImageView
android:id="#+id/Dartboard"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/desc_dartboard"
android:src="#drawable/dartboard" />
<hhs.week3.dartboard.VerticalSeekBar
android:id="#+id/seekBarVertical"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="bottom"
android:thumb="#drawable/thumbhorizontal"
android:layout_marginBottom="40dp" />
<SeekBar
android:id="#+id/seekBarHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:thumb="#drawable/thumbhorizontal" />
</RelativeLayout>
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="60dp"
android:background="#333">
<Button
android:id="#+id/fire"
style="#style/button"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:text="#string/fire" />
<Button
android:id="#+id/settings"
style="#style/button"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:text="#string/settings" />
</LinearLayout>
</LinearLayout>
I got it working half decently, but it requires me to give the RelativeLayout bit a fixed height, making it look right on my phone, but not on others.
How do I best approach this?
Use the LinearLayout layout_weight mechanism to assign all remaining space to your RelativeLayout:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1"
... />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="60dp"
... />
</LinearLayout>
Try following code
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".DartboardActivity" >
<RelativeLayout
android:id="#+id/game_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/buttons"
android:layout_alignParentTop="true"
android:background="#drawable/ic_launcher"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin" >
</RelativeLayout>
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_alignParentBottom="true"
android:background="#333"
android:orientation="vertical" >
</LinearLayout>
</RelativeLayout>
I removed LinearLayout and replaced with RelativeLayout. This will allow you to set your LinearLayout stick to bottom.
I was able to achieve the same result by using below code. Basically, the parent layout is one Linear layout and the first child element is a scrollview so it can squeeze its content when the keyboard is shown. Also note the use of the android:layout_height="0dp" and android:layout_weight="1" used with the scrollview
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/wrap"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:id="#+id/wrap2"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<LinearLayout
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
</LinearLayout>
</ScrollView>
<FrameLayout
android:id="#+id/buttonsPanel"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#333" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="action buttons" />
</FrameLayout>
</LinearLayout>
Try this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
