put the logo webview - Android

I want to put a logo on the corner of the webview. Because I don't want users to download pdf while pdf is loading. So I want to add a logo to the top right corner of the webview. But when I add the logo it stays under the webview and is not visible. How can I show it on top of the webview and in the top right corner?

</RelativeLayout>

Ok so I noticed you already received some answers for your question but both seemed to miss some points I noticed hence decided to post an answer.
First, as #Ryan's answer mentioned you will need to put your ImageView after WebView in order for it to be drawn on top, otherwise it would always be below.
Second, upto this your ImageView should be on top-left, but since you require it to be on the Top-Right corner you will need to add
android:layout_alignEnd="#+id/webviewAntreman"
So your ImageView code written after the WebView woul be something like this.
<ImageView
android:id="#+id/imageAntremanLogo"
android:layout_alignTop="#+id/webviewAntreman"
android:layout_alignEnd="#+id/webviewAntreman"
android:src="#drawable/logo_kopya"
android:layout_width="100dp"
android:layout_height="100dp" />
As a note, android:elevation as in #Rumit's answer requires minimum API level 21, so if your app supports version below Android 5.0 this property won't work on those otherwise it's fine.
In the rare case none of this works, make use of a FrameLayout for what you need to achieve

Put the ImageView tag after the WebView tag in the XML. Views are drawn with the last one on top.

You can try with android:elevation="5dp" property on ImageView to elevate it from WebView.
<ImageView
android:id="#+id/imageAntremanLogo"
android:layout_alignTop="#+id/webviewAntreman"
android:src="#drawable/logo_kopya"
android:elevation="5dp"
android:layout_width="100dp"
android:layout_height="100dp" />

Spinner in Toolbar Example in Xamarin for Android

I am trying to implement a spinner in the toolbar of my navigation drawer.
My initial toolbar layout included the following xml code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/languagetoolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:fitsSystemWindows="true"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light" >
<Spinner
android:id="#+id/toolbar_languageSpinner"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:entries="#array/array_languageSelect"
android:gravity="right" />
</android.support.v7.widget.Toolbar>
The thing is that there does not seem to exist to be an example that seem to show the implementation method using Xamarin. I have tried to use the following resources :
https://dabx.io/2015/01/02/material-design-spinner-toolbar-style-fix/ &
http://android-pratap.blogspot.co.za/2015/01/spinner-in-toolbar-example-in-android.html
x
The short comings of the two examples is that using Xamarin I have found that I cannot use .setAdapter as it only exists as an interface
The look that i want in the tool bar is similar to the image in the first link but having the spinner to the extreme right.

The solution that I finally found is explained perfectly by prathap in http://android-pratap.blogspot.co.za/2015/01/spinner-in-toolbar-example-in-android.html. The solution involves adding the spinner to the toolbar layout like below:
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/languagetoolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<Spinner
android:id="#+id/toolbar_languageSpinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:entries="#array/array_languageSelect"
style="#style/MyTheme"
android:gravity="right" />
</android.support.v7.widget.Toolbar>
Then the code that follows will require the user to populate the spinner in the code from their activity.

Android Custom TabLayout: Icon overlays content

I'm looking for a custom TabLayout. The icon of the Tab in the middle needs a margin to overlay the content. Please check out the image below.
What I've tried so far
Tab.setCustomView() with a margin. That doesn't overlay the content though.
Looked for TabLayout libraries that give such flexibility. Didn't find anything that fits my need.
Re-invent the wheel?
Since I don't need any complicated scrolling functionality, I could develop my own TabLayout with a couple ViewGroups,TextView and ImageView. Before I have to do that:
Do you know of any library that would do that?
How would you approach it?
Any help would be greatly appreciated!

I achieved that by the combination of a custom library and the floating action button.
The library: MagicIndicator on GitHub
I set the icon of the middle fragment to an empty icon and positioned the floating action button in the middle to overlay the TabLayout. It looks like this:
My activity layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

</android.support.design.widget.CoordinatorLayout>

Overlaying content above AppBarLayout using new Material Design

I want to achieve something like that. (not the FAB or the Snackbar). How can i create a layout, overlaying the AppBarLayout? Like this! (For Example)
Like Play Store:
My AppBarLayout with CoordinatorLayout and NestedScrollView with RelativeLayout as content looks like this:
<android.support.design.widget.CoordinatorLayout 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:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="#dimen/_118sdp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsingToolbarLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="#color/mpc_pink"
app:expandedTitleMarginStart="#dimen/_40sdp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<de.mypostcardstore.widgets.ItemImageView
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:src="#color/mpc_pink"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.7" />
<android.support.v7.widget.Toolbar
android:id="#+id/article_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:minHeight="?attr/actionBarSize"
app:contentScrim="#color/mpc_pink"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?android:colorBackground"
android:fillViewport="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<RelativeLayout
android:layout_width="match_parent".....>
It would be awesome if someone could help me out. I can not find anything on the internet...
Thanks in advance!

Just add something like
app:behavior_overlapTop="64dp"
to your NestedScrollView and it will be placed above the expanded toolbar.
In addition, you should add something like
app:expandedTitleMarginBottom="70dp"
to your CollapsingToolbarLayout so the title does not appear under your overlaid scroll content.

It's quite simple, really. You could achieve that by using a combination of ToolBar, FrameLayout, and your content view (could be a ListView like your first example, or anything).
The idea is to make your FrameLayout possess the same color as your ToolBar, giving the illusion of ToolBar being much larger than it is. Then all that is left to do is to make your content view be the last (or in API 21 and above: possess the highest elevation attribute) so that it would appear as if it floats above the aforementioned FrameLayout.
See my illustration below:
Now that you got the big idea, below is some real live XML snippet for doing such thing. (I actually use this layout in one of my apps) :
<!-- Somewhere in your layout.xml -->
....
<android.support.v7.widget.Toolbar
android:id="#+id/tb_toolbar"
android:layout_width="match_parent"
android:layout_height="#dimen/abc_action_bar_default_height_material"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:contentInsetStart="72dp"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<!-- This is the 'faux' ToolBar I've been telling you about. This is the part that will be overlaid by the content view below. -->
<FrameLayout
android:id="#+id/v_toolbar_extension"
android:layout_width="match_parent"
android:layout_height="64dp"
android:layout_below="#+id/tb_toolbar"
android:background="?attr/colorPrimary"
android:elevation="2dp"/>
<!-- Normally, I use this FrameLayout as a base for inflating my fragments. You could just use put your content view here. -->
<FrameLayout
android:id="#+id/ly_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/tb_toolbar"
android:elevation="3dp"/>
....
Note that my ly_content has higher elevation value than that of v_toolbar_extension. This is what will give you that desired 'overlaid toolbar' effect.
Last but not least, you would want to add this line somewhere in your activity's onCreate() :
/* Assuming mToolbar exists as a reference to your ToolBar in XML. */
setSupportActionBar(mTbToolbar);
getSupportActionBar().setElevation(0);
What that codes woud do is to set your ToolBar elevation to zero; removing preset shadows that were given as a default to ToolBars. If you don't do this, said shadow will create a "seam" between your ToolBar and your FrameLayout, thus breaking the illusion of those two being the same.
p.s., It is also important to give your content view a padding on each side. Doing so, your content view will not cover the entire width of the screen (which would render this effect useless).
Note: I see some good answers here that mentioned the absence of FrameLayout and instead making the ToolBar taller. While in theory it might work as well as my proposed solution, you might have problems when trying to manipulate scrolling; by doing that, you won't be able to separate ToolBar and its extension. You'll be forced to either make the Toolbar static or scroll all of the ToolBar altogether (makes scrolling a bit weird).
Add to that, the fact that you can't easily assign a custom drawable into a Toolbar. Hence makes it hard to follow the Google Play example you've given above. While if you're using my solution, all you'd need to do is just make your Toolbar transparent and assign the drawable to the FrameLayout instead.

I had a similar requirement and I achieved it as below.
Your activity theme should extend Theme.AppCompat.Light.NoActionBar.
I created a Layout XML File as:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_main"
android:layout_width="match_parent"
android:layout_height="#dimen/action_bar_size_x2"
android:background="#color/colorPrimary"
android:minHeight="?attr/actionBarSize" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="#dimen/action_bar_size"
android:orientation="vertical" >
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="#string/app_name"
android:textSize="24sp" />
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
And the Activity should be something like this:
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar maintoolbar = (Toolbar) findViewById(R.id.toolbar_main);
setSupportActionBar(maintoolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
}
I got a view like this :

I did try to implement effects like you referred which is called Card Toolbar in Android, and it did work as expected. Here is my layout, Take a look at it:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/background_material_light" >
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="#dimen/toolbar_double_height"
android:background="?attr/colorPrimary" />
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="#dimen/cardview_toolbar_spacer"
android:layout_marginRight="#dimen/cardview_toolbar_spacer"
android:layout_marginTop="?attr/actionBarSize"
app:cardBackgroundColor="#android:color/white">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize" />
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:alpha="0.12"
android:background="#android:color/black" />
</LinearLayout>
</android.support.v7.widget.CardView>
</FrameLayout>
Hope you'll be inspired.

Add views to Toolbar

I've searched for this question but haven't found a useful answer yet.
I am trying to create a Toolbar with some kind of edittext inside of it.
It should look like this:
How should my XML file look like? Currently it looks like this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/activity_main_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="8dp"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="#+id/activity_main_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/title"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_marginEnd="16dp"
android:layout_marginStart="16dp"
android:layout_marginTop="16dp"
android:textSize="22sp"/>
</LinearLayout>
</android.support.v7.widget.Toolbar>
</LinearLayout>
The activity looks like this:
private Toolbar toolbar;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.acitivty_main);
toolbar = (Toolbar)findViewbyid(R.id.activity_main_toolbar);
setSupportActionbar(toolbar);
}
But the result is some Edittext which is right in the center of the Toolbar, letting no space for the toolbar title (please ignore the "save" menu button)
Now my question is,
How do I correctly add one or more views to the toolbar below the main actionbar height?
Could you recommend me some example or tutorial page?
What kind of EditText is used in the shown image with the floating hint?
Thanks in advance

Well first I think it easy to answer the second and third question first, you can find that information in the "Android Developer Blog" in "Android Design Support Library". Here the link:
http://android-developers.blogspot.co.uk/2015_05_01_archive.html
Just scroll down till you find the section called "Floating labels for editing text" and sorted.
Now for the first question, what I did was I made a "Toolbar" layout (won't be able to elaborate too much here as I'm busy at the moment) and then added it to the layout. The code is below:
Toolbar Layout:
<?xml version="1.0" encoding="utf-8"?>
<!-- NOTE: Use To Maintain Structure Of Actionbar -->
<Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:background="#009688"
android:id="#+id/toolBar"
android:elevation="2dp">
<!-- NOTE: Required For Top Section Structure -->
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="vertical">
<EditText
android:background="#android:color/transparent"
android:hint="#string/note_title"
android:textColorHint="#FFFFFF"
android:id="#+id/actionTitle"
android:paddingRight="16dp"
style="#style/ActionText"/>
<TextView
android:id="#+id/textDate"
style="#style/ActionDate"/>
</LinearLayout>
</Toolbar>
Adding it to the Layout File
<?xml version="1.0" encoding="utf-8"?>
<!-- NOTE: Layout For Edit Note Activity -->
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:fitsSystemWindows="true">
<!-- NOTE: Assigned Custom Toolbar -->
<include
android:id="#+id/toolBar"
layout="#layout/tool"/>
</RelativeLayout>
And that should sort you out (You can then mess about with the actionbar properties to clean it up aka: getActionBar().setElevation(0); and
getActionBar().setTitle("");
