AXML | Android binary XML file parser

I want to change the tabindicatorcolor in MainPage.xaml but I cannot see the properties tabindicatorcolor. They mention here using AppCompat, I already imported the Android Support Library v7 AppCompat from NuGet and mentioned to check it here Resources/layout/Tabbar.axml but I cannot see in my MyProject.Android project.

What else did I missed? Sorry, just new with programming. Edit: I'm using Xamarin.Forms

I use project hybridWebView standart. Xamarin.Forms - HybridWebView Custom Renderer

1. If i use the html file that is in the Android project - Content / index.html - Everything works.
2. If I use html file which is hosted by mysite.com - The first time the hybridWebViewPage.axml page is loaded, I get the data in a variable var data. If I go to another page, and then go back to the hybridWebViewPage.axml page, I do not get data in the variable var data. hybridWebView.RegisterAction(data => DisplayAlert("Alert", "Hello " + data, "OK"));

Why is this happening?

In my cross-platform Xamarin Forms app, specifically on Android, I want to be able to customize the appearance of the items in the navigation bar of the Xamarin.Forms.TabbedPage. In particular, I want to be able to change the background for focused items in the bar from a solid light grey cropped circle (see image below) to a different shape, for example a green rectangular frame (the actual shape is not important).

I know how to change the background for an item depending on state, my problem is I cannot find which style or similar I need to modify to change the background for the navigation items in TabbedPage.

Typically for the Android app project of a Xamarin Forms app, the Tabbar.axml file is contained in the Resources/Layout folder, but any change I make in this file does not seem to apply to the appearance of the navigation tab. For example, I tried to add the following line:

i have a recyclerview the has an edittext in each row. the user can change the value of the edittext as he wishes but it should not be left empty for the values will be saved in a database. for this i'm trying to check if the edittext is empty. if any row has an empty edittext, the user is given a message when he wants to save that there is an empty value. this is the code that i wrote:

I'm trying to create a button that navigates to another page in mvvmCross. The application boots up correctly but when the button is pressed nothing happens.

I'm using a modified version of the Bable project it has been updated to use mvvmcross 8. As well as trimmed down to only contain what I think is the minimum to move between two View models.

Here is the currently code:

FirstViewModel.cs

I'm trying to create a ListView inside an AllertDialog in Xamarin Android.

I've searched along and found some examples, but I didn't found any with a ListView and custom adapter inside an AlertDialog, using C#.

The closest that I found whas the sample bellow (Thanks to Macoratti). This one hasn't AlertDialog. I've tryed to adapt but I get System.NullReferenceException: 'Object reference not set to an instance of an object.'.

Because I failed to insert two more lines in Info Window on the pin on xamarin.forms.maps on iOS project I managed to put them over Info Window like this:

In the android project I had two files with an extension .axml In which I added two and so I managed to add two more lines in InfoWindow on the pin.

But here I don't have (or don't know where) to add two more fields in the pin window itself so add them this way:

1. I add my objects who come from database with this code:

I receive error: CS0103: The name 'imageListView' does not exist in the current context (CS0103) (MaritsaTundzhaForecast) in c# code when I trying to check the condition from the column in ListView and depending on the value of one column to show a different picture in other column.

This is my MainPage.axml code:

I want to set second label in info window on xamarin map. I use this example.

So exactly I want to set one variable who come from date base on info window like a second label:
