I have a static button in an activity view:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="#+id/layout_record"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >
<Button
android:id="#+id/button_review"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="Review"
android:color="#e5e5e5"
android:alpha="1" />
</RelativeLayout>
Later some code will insert a SurfaceView derived class behind the button (doing something like: getViewById("layoutRecord".addChild(surfaceView, 0))
The problem is the button is transparent and hard to see, even though I am setting the color and alpha of the button. I believe I have the controls stacked in the right order because if I call addChild(surfaceView,1) then the surfaceView completely hides the button.
Why is the button still transparent?
android:color="#e5e5e5" this property not there in Button only textColor,backgrount etc., not in color
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="#+id/layout_record"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >
<Button
android:id="#+id/button_review"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="Review"
android:background="#e5e5e5"
android:alpha="1" />

I am designing a layout in which i have 3 buttons at the center of the screen and a grid view at bottom f the screen. in the grid view i am adding images. but when i am adding images the buttons are fixed at their places and after many images gridview start covering the buttons starting from bottom. is there any way i can dynamically adjust the screen when the number of image increase.
my activity.xml file

In the Google's Material Design specs they often shown the Floating Action Button lying over half the toolbar and have over the content.
http://www.google.com/design/spec/components/buttons-floating-action-button.html
But I have tried a few variations and there is still a gap between the toolbar and content, caused by the button.
<LinearLayout>
<include layout="#layout/toolbar" />
<include layout="#layout/fab_button" />
<ScrollView>
Content
</ScrollView>
</LinearLayout>
I have also tried placing both toolbar and FAB button in a FrameLayout and it also had the gap.
The FAB button code was taken from Google's samples, and I haven't had issues with having it overlap at the bottom of over a RecyclerView.
Is there a way to achieve this look shown in the Material Design Specs.
Add layout_anchor property in FAB and set it to Top View.
Make CoordinatorLayout as your root view, this would be best layout practice.
You can set FAB gravity using layout_anchorGravity attribute in FAB.
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

android:layout_height="match_parent"

android:layout_weight="0.6"
android:background="#android:color/holo_blue_bright"
android:orientation="horizontal"/>
<LinearLayout
android:id="#+id/viewB"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.4"
android:background="#android:color/holo_green_light"
android:orientation="horizontal"/>
</LinearLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:clickable="true"
android:src="#drawable/ic_done"
app:layout_anchor="#id/viewA"
app:layout_anchorGravity="bottom|right|end"/>
</android.support.design.widget.CoordinatorLayout>

Hope this could help you.
Using Relative layout is the easiest to position a FAB in between 2 views. You can use elevation parameter for the fab to get it over the toolbar. Set the elevation of the FAB more that that of the toolbar.
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="4dp"
android:background="?attr/colorPrimary"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<ListView
android:id="#+id/listview"
android:layout_below="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<com.getbase.floatingactionbutton.FloatingActionButton

android:layout_alignParentEnd="true"
android:layout_marginRight="8dp"
android:layout_marginEnd="8dp"
android:elevation="8dp"
android:layout_marginBottom="-32dp"

I am developing custom menu item by calling action layout, but when i am taping that action menu that pressing color is not applying total height giving some top and bottom margin.
Below is my code:
<?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:gravity="center">
<ImageView
android:minWidth="56dp"
android:id="#+id/voicemailNotificationCounter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:clickable="true"
android:background="#drawable/ab_pressedicon_bgcolor"
android:contentDescription="#string/voicemailnotification"
android:src="#drawable/ab_voicemail">
</ImageView>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/vmNotificationTextCounter"
android:text="1"
android:visibility="visible"
android:layout_alignRight="#+id/voicemailNotificationCounter"
android:layout_marginRight="10dp"
android:gravity="center"
android:textColor="#fff"
android:includeFontPadding="false"
android:background="#drawable/notification_alertbg"
android:textSize="12sp"/>
</RelativeLayout>
Part of the problem is that you're not using an ImageButton.
Combining an image with text is possible with an ImageButton. You can even independently adjust the text and the image inside that ImageButton.
Hopefully, an ImageButton will work inside an action menu, I haven't actually tested that part yet.
I am making an app for my university's SafeWalk program and I am trying to make an activity that will display a map fragment with a button bar below it with emergency call buttons. The problem I am running in to is that when I load the following layout file, only the map fragment is displayed, and not the buttons along the bottom.
Note: I am also using a navigation drawer in this layout so I have included that code in case it is conflicting.
I have tried changing the layout_width and layout_height values of the two parent FrameLayouts
and I only can obtain one of two results, a full page of map, or a full page of my buttons (stretched to the top). I can attach the layout for the CallButtonFragment if necessary, but it is a horizontal linear layout with the button bar style containing two buttons.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:orientation="vertical" >
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" >
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_below="#+id/content_frame" >
<fragment
android:id="#+id/titles"
android:name="edu.purdue.SafeWalk.CallButtonFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</RelativeLayout>
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
Following the suggestion of Android-er-naut below, I have this result:
(It is an improvement, but the buttons need to be a bit larger and fit the width of the screen.)
How about this -
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" >
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" >
<fragment
android:id="#+id/titles"
android:name="edu.purdue.SafeWalk.CallButtonFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</LinearLayout>
I'm relativity new to Android development, but I do like to think I catch on fast. I've been re-working an app I made for my softball team. Previously I've used Google's App Inventor, but have run into many shortcomings with it, so I am now attempting to re-work it using Eclipse.
Anyway, to the point. I seem to be having some excess padding being added to my LinearLayout, which I'm not sure where it is coming from.
I am using the TabHost to create the tabs on top (a modified version of Google's Tabs example).
Layout XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_linlay_parent"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<RelativeLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background"
>
<!-- Allow the "Tabs" to scroll horizontally -->
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:scrollbars="none"
>
<!-- The "Tabs" widget -->
<TabWidget
android:id="#android:id/tabs"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#000000"
/>
</HorizontalScrollView>
<!-- Provide the "Content" the ability to vertically scroll -->
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="65dp"
>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<LinearLayout
android:id="#+id/tabdata"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
</LinearLayout>
</FrameLayout>
</ScrollView>
</RelativeLayout>
</TabHost>
</LinearLayout>
I believe the issue has to with the android:layout_marginTop="65dp" in the ScrollView, but if I remove it, my Tabs disappear (I'm assuming my tabcontent is just being overlayed over the top of it).
Lastly, here's a screen shot showing an example of what I'm experiencing (Disreguard the XML string, I still need to massage that part. I just wanted to show an example with data.).
http://kahunaball.com/android/screenshot_0.jpg
After starting the XML over from scratch and taking small steps forward, I was able to re-work the XML and resolve the excess padding from my layout.
I'm not 100% sure which change made the difference, but my suspicions are that changing the RelativeLayout to LinearLayout and moving the LinearLayout and TableLayout outside of the FrameLayout were what had done the trick.
For others that may stumble across this and would like to see my new XML which resolved the issue, here it is:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:scrollbars="none">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#000000" />
</HorizontalScrollView>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent" >

android:gravity="center_horizontal" />
