<Button
android:id="#+id/button_send"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:background="#drawable/buttons"
android:drawablePadding="10dp"
android:gravity="left"
android:padding="15dp"
android:text="Button"
android:textColor="#fff"
android:textSize="15sp" />
Above is my code for Button in My xml file.
My button.xml code is
<item android:drawable="#drawable/btn_bg_hover"
android:state_pressed="true" />
<item android:drawable="#drawable/btn_bg_default"
android:state_focused="true" />
<item android:drawable="#drawable/btn_bg_default"/>
kindly help me how to add border to that button.
Note: #drawable/btn_bg_hover is image
User stroke tag Android - border for button
<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient android:startColor="#FFFFFF" android:endColor="#00FF00" android:angle="270" />
<corners android:radius="3dp" />
<stroke android:width="5px" android:color="#000000" />
You have to make your custom background drawable file and use it, the stroke property is the one you have to use for making border.
Steps :
Go to res -> drawable -> by right click -> new -> android drawable resource
copy paste this code
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#FFFFFF"
android:endColor="#00FF00"
android:angle="270" />
<stroke android:width="5px" android:color="#000000" />
</shape>
Here you see the stroke you can change values to make it in your way.
and use it as any components background by
<android:Background ="#drawable/yourCustomBorder.xml"> for example.

I have a Xamarin Forms TabbedPage which contains a NavigationPage and I'm setting a ToolbarItem with two white icons. For some reason they appear black when my icons are white:
Here is my Xaml code:
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:views="clr-namespace:Pick.Views"
x:Class="Pick.Views.MainView"
xmlns:utility="clr-namespace:Pick.Utility"
utility:ViewModelLocator.AutoWireViewModel="False">
<NavigationPage Title="{Binding Strings[Menu_MyPools]}">
<x:Arguments>
<views:PoolsView BindingContext="{Binding PoolsViewModel}"/>
</x:Arguments>
<NavigationPage.ToolbarItems>
<ToolbarItem Command="{Binding CreatePoolCommand}" Order="Primary" IconImageSource="ic_add_white_36dp.png">
</ToolbarItem>
<ToolbarItem Command="{Binding JoinPoolCommand}" Order="Primary" IconImageSource="ic_login_white_36dp.png">
</ToolbarItem>
</NavigationPage.ToolbarItems>
</NavigationPage>
I have tried setting AppThemeBinding and changing Styles.xml but nothing seems to work:
<ToolbarItem Command="{Binding CreatePoolCommand}" Order="Primary">
<ToolbarItem.IconImageSource>
<OnPlatform x:TypeArguments="ImageSource">
<On Platform="Android" Value="{AppThemeBinding Light=ic_add_white_36dp,Dark=ic_add_white_36dp}"/>
<On Platform="iOS" Value="{AppThemeBinding Light=ic_add_white_36pt,Dark=ic_add_white_36dp}"/>
</OnPlatform>
</ToolbarItem.IconImageSource>
</ToolbarItem>
Any ideas?
Here my styles.xml:

I just figured out my issue. Turns out that I had XML files corresponding to my images which had a vector definition inside. Not sure if those were automatically created by one of my material design icons VS extension. Once I remove, I see my icons in the right color.
I wanted to use TableLayout nevertheless seems it's not available. What could be wrong?
Check below:
The TableLayout is a Xamarin.Android not a Xamarin.Forms Layout. Read more about the table layout here In Xamarin.Forms you use TableView, read more about here.
You write Xamarin.Forms views usually in .xaml files with .xaml.cs code behind. You write native Android views in .axml or .xml with no code behind.
A table for native android;
table_content.xml
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1">
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_column="1"
android:text="Open..."
android:padding="3dip"/>
</TableRow>
</TableLayout>
A Xamarin.Forms sample table view;
TableContentPage.xaml
<ContentPage ...>
<TableView Intent="Settings">
<TableRoot>
<TableSection Title="Ring">
<SwitchCell Text="New Voice Mail" />
<SwitchCell Text="New Mail" On="true" />
</TableSection>
</TableRoot>
</TableView>
</ContentPage>
I'm trying to create a custom slider in Xamarin.Forms, I have created a custom renderer for this purpose
protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.Slider> e)
{
base.OnElementChanged(e);
if (e.NewElement != null)
{
// Set custom drawable resource
Control.SplitTrack = false;
Control.SetProgressDrawableTiled(
Resources.GetDrawable(
Resource.Drawable.custom_progressbar_style,
(this.Context).Theme));
Control.SetThumb(Resources.GetDrawable(
Resource.Drawable.custom_thumb,
(this.Context).Theme));
// Control.Bottom = 30;
}
}
Here I'm loading two xml files one for progress bar and the other one is for slider's thumb. Progress bar is loaded from custom_progressbar_style and Thumb is being loaded from custom_thumb both of them are placed under Resource/drawable.
Progress bar xml content:
<?xml version="1.0" encoding="UTF-8" ?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background" android:height="10dp">
<shape>
<corners android:radius="3dp"/>
</shape>
</item>
<item android:id="#android:id/secondaryProgress" android:height="10dp">
<clip>
<shape>
<corners android:radius="3dp"/>
</shape>
</clip>
</item>
<item android:id="#android:id/progress" android:height="10dp">
<clip>
<shape>
<corners android:radius="3dp"/>
</shape>
</clip>
</item>
</layer-list>
Thumb xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" android:layout_gravity="center_vertical">
<!-- Larger white circle in back -->
<item >
<shape android:shape="oval">
<solid android:color="#f0f0f0"/>
<size
android:width="30dp"
android:height="30dp"/>
</shape>
</item>
<!-- Smaller blue circle in front -->
<item>
<shape android:shape="oval">
<!-- transparent stroke = larger_circle_size - smaller_circle_size -->
<stroke android:color="#android:color/transparent"
android:width="10dp"/>
<solid android:color="#6766f6"/>
<size
android:width="15dp"
android:height="15dp"/>
</shape>
</item>
</layer-list>
I have fixed the height of my custom slider to 10dp which is causing alignment issues with the slider's thumb. Can you suggest how I can overcome this alignment issue.
According to your description, I test your code and modify your custom_progressbar_style.xml, and I have on problem.
This is my custom_progressbar_style.xml, please take a look:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#android:id/background">
<shape>
<corners android:radius="15dip" />
<gradient
android:startColor="#d9d9d9"
android:centerColor="#e6e6e6"
android:endColor="#d9d9d9"
android:centerY="0.50"
android:angle="270" />
</shape>
</item>
<item android:id="#android:id/secondaryProgress">
<clip>
<shape>
<corners android:radius="15dip" />
<gradient
android:startColor="#e6b3e6"
android:centerColor="#ffcce0"
android:endColor="#e6b3e6"
android:centerY="0.50"
android:angle="270" />
</shape>
</clip>
</item>
<item android:id="#android:id/progress">
<clip>
<shape>
<corners android:radius="15dip" />
<gradient
android:startColor="#ff0066"
android:centerColor="#ff00ff"
android:centerY="0.50"
android:endColor="#cc0052"
android:angle="270" />
</shape>
</clip>
</item>
</layer-list>
Update:
<StackLayout>
<local:customslider HeightRequest="10" VerticalOptions="CenterAndExpand" />
</StackLayout>
Update again:
protected override void OnLayout(bool changed, int l, int t, int r, int b)
{
base.OnLayout(changed, l, t, r, b);
if (Control == null)
return;
SeekBar seekbar = Control;
Drawable thumb = seekbar.Thumb;
thumb.SetBounds(thumb.Bounds.Left, -4, thumb.Bounds.Left + thumb.IntrinsicWidth, thumb.IntrinsicHeight-4);
}
How can I add an image to a tool bar item on Android? I've managed to do it for iOS by assigning a new view to the item's CustomView property.
I want text and an image. Not one of the other.
How does one access tool bar items on Android?
You can use below code for use ToolBarItem.
<ContentPage ...>
<ContentPage.ToolbarItems>
<ToolbarItem Text="YourText" x:Name="YourName" Icon="image.png" Clicked="yourName_clicked"></ToolbarItem>
</ContentPage.ToolbarItems>
<ContentPage.Content>
...................
....................
</ContentPage.Content>
You can check this post to teach how to add an image to the toolbar.
But , in Toolbar.axml you can add your image
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<ImageView
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:scaleType="fitCenter"
android:src="#drawable/xamarin_logo"
android:layout_gravity="center" />
</android.support.v7.widget.Toolbar>
How to create a floating toolbar like the following image as proposed in the material design guidelines and in the Google Map application.
I've worked with the Toolbar before and all the comments from CommonsWare are absolutely correct.
The Toolbar widget (https://developer.android.com/reference/android/support/v7/widget/Toolbar.html) have absolutely nothing special or different than any other Viewgroup and does not behave differently than any other ViewGroup.
Put it inside a FrameLayout, put a layout_margin parameter on it, make the layout_width NOT match_parent and that's it.
Put it inside an LinearLayout with orientation=horizontal and you can use the layout_weight to control the size in percentage. Or just use plain dip if that suits your needs.
Since you are following the Material Design concept I am assuming your are using Coordinator Layout as your Main Layout and Not Frame Layout.
Before anything else we need to declare the important dependencies.
dependencies {
compile 'com.android.support:design:22.2.1'
compile 'com.android.support:cardview-v7:22.2.1'
}

I think Mark's suggestion for picking up the CardView "look" in the comment above deserves this derivative answer:
Just put a Toolbar in a CardView:
<android.support.v7.widget.CardView
android:id="#+id/map_toolbar_container"
android:layout_width="#dimen/whatever_you_want"
android:layout_height="wrap_content"
android:layout_margin="8dp"
app:cardElevation="8dp"
app:cardBackgroundColor="#324">
<android.support.v7.widget.Toolbar
android:id="#+id/wld_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"/>
</android.support.v7.widget.CardView>
Just Add the following code....
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:id="#+id/toolbar"
android:background="#color/colorPrimary"
android:elevation="8dp"
android:layout_margin="5dp"
>
//add whatever elements you want to add in here.
</android.support.v7.widget.Toolbar>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
**android:layout_margin="10dp"
android:elevation="5dp"**
/>
Here is the code for the floating toolbar, just copy and paste.
This is an example of a floating toolbar using Appcompat, It can be working under many layouts like Relative, Coordinator, or DrawerLayout. You can increase elevation to make it more effective.
