Android - Forecast.io icon label to custom font: weather-icons - android

I'm currently building a weather app using the forecast.io api.
They provide custom font for Forecast.io, as well as for other apis such as Yahoo. I'm not sure about how to proceed to use their API mapping.
For instance, I receive "partly-cloudy-night" and this should render the icon.
I would welcome advices or clues on how to proceed.
Thanks a lot,

You have to use the ttf file il your android project, and convert the css to xml string ressource.
I did it for Web Hosting hub glyph (a bit like font awesome but many more icons).
See https://github.com/neoteknic/whhg-to-android
I can reuse my convertion script an make a repo with these icons.
Edit :
This is for you :
https://github.com/neoteknic/weather-icons-to-android
To use it (I prefer load only once the typeface and make it available globally) :
public class YourAppName extends Application {
public static Typeface weatherIcons;
#Override
public void onCreate(){
YourAppName.weatherIcons= Typeface.createFromAsset(getApplicationContext().getResources().getAssets(), "fonts/weathericons-regular-webfont.ttf");
super.onCreate();
}
}
Then when you wanna use it :
TextView myicon=(TextView) findViewById(R.id.myicon);
myicon.setTypeface(YourAppName.weatherIcons);
myicon.setText(R.string.wi_day_snow_wind);

Nativescript and FontAwesome

I am trying to use icon font FontAwesome in Nativescript application, which is possible according to this article https://www.nativescript.org/blog/mobile-app-best-practices---use-font-instead-of-image-to-show-an-icon
I did everything that is described in that article:
Added .ttf in app/fonts
Added class in app.css
.fa{
font-family: "FontAwesome";
}
Used it in XML like so
text="" class="fa"
But result is rather disappointing:
I also tried the "\uf230" syntax, but that renders as plain text.
What am I doing wrong?
Could be a few things. Does it work on iOS? As your CSS definition is iOS compatible, not Android as Android needs the actual filename (without extension) whereas iOS needs the font name. So I have this to be xplatform-ready (the file is 'fontawesome-webfont.ttf'):
.fa {
font-family: 'FontAwesome', fontawesome-webfont;
}
The \f005 syntax is OK (<Label class="fa" [text]="'\uf005'"></Label>), but I'm using the splendid nativescript-ngx-fonticon plugin (there's also a non-Angular one) to be able to do this instead:
<Label class="fa" [text]="'fa-shopping-basket' | fonticon"></Label>
To make it work, you must make sure that the "fonts" directory is inside the "app" folder and that the following files exist:
font-awesome.eot
font-awesome.ttf
I opted to adopt this font as the default of my application, so I do not have to worry about where I'm going to use it and how much to enter the right class, everything is getting very good and the result is perfect.
In CSS, you only have to define a selector according to your interest for the source to be used, so just use the directive:
page {
font-family: 'FontAwesome'
}
Then where you want an icon, just use an html entity that represents it as it searches the site: http://fontawesome.io/icons/

You can see this video where I was based to start. It corrects in the video the extension used to be attentive.

Create and change to new view with React Native

We're currently working on an app for one of our customers, and we've decided to use React Native as the technology to use for creating the app.
I'm pretty new to this technology, and I'm used to developing apps with either C# or Java, where I have full-fledged IDEs that provide all the functionality I need.
I'm currently creating a login screen, and would like to change to different views, depending on the type of login (e.g.: Facebook, Google, Twitter, Email, etc.).
How do I go about doing this. As I mention, with an IDE, it'd be a shortcut like SHIFT+ALT+A or something to create a new item, select type, name it and the IDE does the rest.
Do I have to create a new xx.android/ios.js file, and somehow call that, or do I need to go in to the native backend of the different projects?
What I tried was something along the lines of:
class Class extends Component {
render() {
<UI code here>
<Button onPress={this.eventHandler}
}
eventHandler(event) {
var xxLogin = new xxLogin();
xxLogin.render();
}
}
class xxLogin extends Component {
render() {
<UI code here>
}
}
But that failed, which I expected.
Thanks in advance for any help!
P.S.: I'm using Mac OS X El Capitan, if that helps.

Xamarin Forms Custom Renderer for Android not displaying

I am trying to render a checkbox in a Xamarin Forms app. There is nothing rendered at runtime, as far as I can tell the renderer is not even getting called.
Does anyone understand what I am missing or doing incorrectly?
Here is my class in Forms:
public class LegalCheckbox : View
{
public LegalCheckbox ()
{
}
}
And my custom renderer class in Droid:
public class CheckBoxRenderer : ViewRenderer<LegalCheckbox, CheckBox>
{
protected override void OnElementChanged (ElementChangedEventArgs<LegalCheckbox> e)
{
base.OnElementChanged (e);
CheckBox control = new Android.Widget.CheckBox(this.Context);
control.Checked = false;
control.Text = "I agree to terms";
control.SetTextColor (Android.Graphics.Color.Rgb (60, 60, 60));
this.SetNativeControl(control);
}
}
Along with the Assembly Directive:
[assembly: ExportRenderer(typeof(demo.LegalCheckbox), typeof(demo.Droid.CheckBoxRenderer))]
Took your code and fired up a new project with it. The code appears to function fine.
Only thin I can think that might be causing you an issue is the location of you assembly attribute. I typically place them just above the namespace declaration in the same file as my renderer.
I threw what I created up on my github maybe you can spot the difference.

Xlabs isn't a bad project but its basically just all the code the opensource community came up with during the first year or so of Xamarin.Forms life. Its not really "Their Labs projects" and considering how much of it is marked up with Alpha Beta and the number of bugs in their issues page it's probably best not to imply that the Xamarin company has anything to do with it.
I am not sure if that is the issue but it would make more sense to me if your LegalCheckbox would inherit from a InputView rather than View.
Also, even if Xamarin.Forms does not have a Checkbox control you can still have a look at their "Labs" project here:
https://github.com/XLabs/Xamarin-Forms-Labs/wiki/Checkbox-Control
(And I can actually see that they inherit from View...)

How to import a SpriteFont into MonoGame

I'm porting a simple tetris-like XNA app to Android, using Mono For Android and MonoGame; I have followed the suggested steps in this link and so far, everything compiles well, and no relevant warnings fire up. However, upon loading the contents, a null parameter exception breaks the program at the point below in my program:
protected override void LoadContent() {
// ...
_font = Content.Load<Microsoft.Xna.Framework.Graphics.SpriteFont>("SpriteFont1");
// ...
}
The content root directory is set in the game constructor class:
public Game2 (){
Content.RootDirectory = "Content";
Content.RootDirectory = "Assets/Content"; // TEST.
//...}
And I have tried several combinations, all to no avail.
I have also tried setting the xnb files as Content as well as Android Assets in the Build Action property; having the linked, copied always, copied only if newer... etc.
Either way, my problem is that I don't really understand WHY and HOW should I do this. I'm rather new to the platform and to XNA as well, so this may very well be a newbie question, but the truth is after several hours banging my head and fists against the monitor/keyboard I feel stuck and need your help.
I have a library that supports variable-width fonts (generated by BMFont) on MonoGame. Unfortunately it is a renderer and so has other code around it. However, the basic idea is very simple. You can take a look at the loader here and the mesh builder (given a string) here. This builder supports fonts that spread characters across multiple pages, too.
Hope this helps!
MonoGame (2.5.1) throws NotImplementedException in ContentManager.Load for SpriteFont type. Have the same not resolved problem. I'm trying not to use DrawString.
For loading textures in Win32 application I use:
Content.RootDirectory = #"../../Content";
var sampleTexture = Content.Load<Texture2D>("Sample.png");
You even must not add it to solution.
For Andoind (MonoDroid) application you must add "Content" folder to your solution and set "Andtoid Asset" in "Sample.png" properties.
Content.RootDirectory = "Content";
var sampleTexture = Content.Load<Texture2D>("Sample.png");

textStyle for Tamil font?

I'm already working on an Android application that displays RSS feed.
My problem is that this feed has some lines in Tamil(which Android still doesn't support)
I found a font online that displays the text right(without converting to Bamini) but the problem is that textStyle doesn't have any effect on it.
so you know any font that can do the job or any thing i have to do to make textStyling?
thanks in advance
What you need to do is import custom fonts on to the phone before using them.
A good way to do that is to include them in the package - in the APK file
Hence you should be having the font in your project when you build the APK file.
Let me give you an example. Assuming your tamil font's name is Harabara.ttf and you have copied it to /assets/fonts
Use this method (anywhere in your activity)
private void initializeFonts() {
font_harabara = Typeface.createFromAsset(getAssets(), "fonts/Harabara.ttf");
}
and call this API from your onCreate like this
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initializeFonts();
setContentView(getViewResourceId());
}
Make sure you have declared this class level variable
Typeface font_harabara = null;
Finally, simply use
myTextField.setTypeface(font_harabara);
tada ! tamil font should now start displaying.

There are hundreds of fonts available online. Did you check some TSCII fonts?
I've written some solutions for Tamil and Android issues. Check it out too.
