Displaying Unicode string in Users control in Xamarin (Android)

Basically, i have a list of Nepali Unicode strings something like {"युनिकोड १ ","युनिकोड २","युनिकोड ३"}.
Now, Firstly, I have a text view in Xamarin (Android) and tried to set the text property using couple of methods:
UnicodeTextView.Text="युनिकोड १"; //direct method
var font = Typeface.CreateFromAsset(_activity.Assets, "kantiput.TTF");//kantiput.TTF Is a Nepali font.
UnicodeTextView.Typeface = font;
var font = Typeface.CreateFromAsset(_activity.Assets, "kantiput.TTF");
UnicodeTextView.SetTypeface(font, TypefaceStyle.BoldItalic);
and none of them worked.
When using the first option nothing was displayed, and on working with last two
and there were some BOX character visible.
For first case when i directly tried to set the value:
Before setting value:
After setting value:
Samething with the ListAdapter.
Can anyone suggest me how can we display unicode sentences in TextView, EditText, Toast ?
I want result something like this :
with TextView :
and here is the weird behavior :
and i tried all those code that are in comment too. Still didn't find any luck.

I am working in android.
In toast I checked like the following:
Toast.makeText (this, "\u0c05 \u0c06", Toast.LENGTH_SHORT).Show();
For first two letters of Telugu alphabet s. It worked.
If you have the font file you can obtain unicode codes for the various glyphs in the online software available at
https://opentype.js.org/index.html
Under page glyph inspector.

I tested your code, the first direct method UnicodeTextView.Text="युनिकोड १"; works fine by my side both with single TextView or TextView in ListView.
Or you may try this code:
if (Android.OS.Build.VERSION.SdkInt >= Android.OS.Build.VERSION_CODES.N)
{
UnicodeTextView.Text = Android.Text.Html.FromHtml("युनिकोड १", Android.Text.FromHtmlOptions.ModeLegacy).ToString();
}
else
{
UnicodeTextView.Text = Android.Text.Html.FromHtml("युनिकोड १").ToString();
}

Android 5+ custom notification XML layout with RemoteViews, set correct icon tint for ImageButton

My app is using a custom Notification layout with RemoteViews.
To display text, the layout is using the following system styles:
android:TextAppearance.Material.Notification.Title
android:TextAppearance.Material.Notification
This works fine.
However, the TextAppearance style can't be used to set the value of android:tint, so I had to hardcode the color.
To my best knowledge, there's no special system style for setting notification ImageButton tint.
Hardcoded colors work fine on the current Android 5+ systems, but some users install custom ROMs with custom dark themes, and the notification looks wrong, i.e. black icons on black background.
Is there any way to get the system notification icon / imagebutton color, and apply it from an XML layout?
Or maybe there's another way to achieve this?

Sorry, But as per my knowledge custom ROM's have separate system designs,configurations and that are not official as well.
So,supporting Custom ROM without knowledge about its design is not possible.
And android APIs are for supporting official ROM's.
Hope it Helps!!

Try this example :
Definition for notification :
// Declare variable
public static Bitmap icon;
// Assign value but this line can be different depends on current
// android sdk vesion ...
icon = BitmapFactory.decodeResource(getApplicationContext().getResources(), R.drawable.YOUR_IMAGE);
mBuilder = new NotificationCompat.Builder(this);
mBuilder.setShowWhen(false);
mBuilder.setDefaults(Notification.DEFAULT_ALL);
mBuilder.setVisibility(NotificationCompat.VISIBILITY_PUBLIC);
mBuilder.setSmallIcon(R.drawable.image1); // One way to load img
mBuilder.setContentText("this text not visible");
mBuilder.setLargeIcon(icon);// This is the line
mBuilder.setPriority(Notification.PRIORITY_DEFAULT);
mBuilder.setContent(contentNotifySmall); // ORI
//mBuilder.setAutoCancel(false);
mBuilder.setCustomBigContentView(contentNotify);
I setup small and big variant for any case , this is important.

for background can you try these attributes...
app:backgroundTint="#color/pay"
---------Or-------------
android:tint="#color/white"

You can take textColor from TextAppearance_Compat_Notification_Title and add it as tint to an image programmatically like this
val remoteViews = RemoteViews(service.packageName, R.layout.notification_layout)
val icon = Icon.createWithResource(context, R.drawable.icon)
val attrs = intArrayOf(android.R.attr.textColor)
with(context.obtainStyledAttributes(R.style.TextAppearance_Compat_Notification_Title, attrs)) {
val iconColor = getColor(0, Color.GRAY)
icon.setTint(iconColor)
recycle()
}
remoteViews.setImageViewIcon(R.id.ibPlayPause, icon)

You can use a notificationlistenerservice to get an active notification. This returns a list of StatusBarNotifications, then just:
StatusBarNotifcation sBNotification = activeNotifications[0];
Notification notification = sBNotification.getNotification();
int argbColor = notification.color;

If you change ImageButton to ImageView in your layout you can update it with
RemoteViews remoteView = getRemoteViews(context);
// load base icon from res
Bitmap baseIcon = BitmapFactory.decodeResource(context.getResources(), R.drawable.base_icon);
// edit Bitmap baseIcon any way for your choose
Bitmap editedBitmap = ...
// update notification view with edited Bitmap
remoteView.setImageViewBitmap(R.id.button_icon, edited);
P.S. you can edit Bitmap like this:

Hope it's help

Punjabi Text not shown properly on Mobile

i have used many punjabi fonts as like bulara_f.ttf , anmollipi , Akaash and many more but every time prolem with one word of punjabi "sihari"
Sihari : Sihari is equivalent to i in pin or thin. Hence forth in this module we will denote sihari vowel with /i/.
in my application only this one word is not shown properly as like in following snapshot... please help...
EDIT
i am using this method
Typeface myfont;
myfont=Typeface.createFromAsset(getAssets(),"font.ttf");
TextView textview = (TextView)findViewById(R.id.TextView01);
//textview.setText("punjabi Text");
textview.setTypeface(myfont);
}

Use bulara_5.ttf and run the code on device it will show correct punjabi words
mTvAbout = (TextView) findViewById(R.id.tv_about);
font = Typeface.createFromAsset(this.getAssets(), "bulara_5.ttf");
mTvAbout.setTypeface(font);
mTvAbout.setText(" ਜਾਣਕਾਰੀ");

Take different typeface from a ttc Android

in my application I must use a custom type of font in a file .ttc . This file conteins different type of typeface (normal, bold, ...). With this code:
textDetails.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/font.ttc"));
I can take one type of typeface. There is a method to take all the typeface?

You can set the style to access the bold and italic typefaces:
http://developer.android.com/reference/android/widget/TextView.html#setTypeface(android.graphics.Typeface, int)
Try this:
textDetails.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/font.ttc"), Typeface.BOLD);

You can load specific font from TTC file using Typeface.Builder (API level 26). This is a snippet from comments in the Typeface source code:
Typeface.Builder buidler = new Typeface.Builder(getAssets(), "your_font_file.ttc");
builder.setTtcIndex(2); // Set index of font collection.
Typeface typeface = builder.build();
Only use setTtcIndex() method if you know the file is TTC.

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?
