I was using Flutter more than a week, and wanted to create an Arabic (right-to-left) app. I was reading Internationalizing Flutter Apps , but it didn't mention how to set the layout direction. So, how to show right-to-left (RTL) layout in Flutter? first you must add flutter_localizations package to your pubspec.yml dependencies: flutter: sdk: flutter flutter_localizations: sdk: flutter now you have two choices : 1. force a locale ( and direction ) on all devices import 'package:flutter/material.dart'; import 'package:flutter_localizations/flutter_localizations.dart'; MaterialApp(

Angular 2+ localization (i18n) rtl support

阅读更多关于 Angular 2+ localization (i18n) rtl support

What is the best practice for adding right to left (rtl) support into a localized Angular 2+ app (e.g. for Hebrew and Arabic languages)? I looked through several tutorials including Internationalization (i18n) but none seem to be covering that. I would expect, for example, the html direction property (e.g. <html dir="rtl"> ) to be added along with translations defined in 18n attributes at the build step of the app. It is possible to add i18n-dir as described in the docs . So, the best approach I found so far is to add i18n-dir dir="ltr" (where ltr is a default direction) to the root element in

阅读更多关于 What is the status of Right To Left languages on Android?

I need to create an application that has strings of many languages, including RTL (right-to-left ) languages. I want to know what is the current status of RTL (Right To Left) support on Android (even on latest API), for example: is it possible to dynamically/statically check if the device's current language is RTL type? I know that it is possible to get the current locale, but i need a more general way to check if the current language is RTL. For example, for English and French it will return false, but for Arabic and Hebrew it will return true. is it possible to set a layout to automatically

How do I position the cursor on the right in EditText

阅读更多关于 How do I position the cursor on the right in EditText

My application uses RTL language (right to left). When the EditText field gets focus, the cursor appears on the left and only when the user starts to type, the cursor (and the RTL text) moves right. When the user clicks "enter" to start a new line, the cursor moves to the left again. When I use android:gravity="right" , the cursor is OK (on the right) but as the user starts to type the text always moves to the the other side (RTL text moves left). Any ideas how I can align text to the right AND keep the text direction? Its works for me <EditText android:id="@+id/editText1" android:layout_width

How to get the “up” button used on the Toolbar?

阅读更多关于 How to get the “up” button used on the Toolbar?

This is a short question: I'm trying to force the action bar (used by a Toolbar) to use LTR alignment. I've succeeded making the layout itself use LTR, but not the "up" button (as I've done here , before Toolbar was introduced) . It seems this view doesn't have an ID, and I think using getChildAt() is too risky. Can anyone help? The answer Here's one way I've found to solve this, based on this answer . I made it so that it is guarranteed to find only the "up" button, and whatever it does, it will revert back to the previous state it was before. Here's the code: @TargetApi(Build.VERSION_CODES
