I've been trying to make a ListView to work as RTL (Right to Left).
I've added the following line in the ListView and LinearLayout properties:
android:layoutDirection="rtl"
and it still shows the list from left to right.
Any ideas?
Thank you all but I solved it with:
android:textDirection="rtl"
I've added it to the ListView and the layouts, and it worked. Next time you should try considering using this too for RTL layouts.
To take advantage of RTL layout mirroring, simply make the following changes to your app:
Declare in your app manifest that your app supports RTL mirroring.
Specifically, add android:supportsRtl="true" to the <application> element in your manifest file.
Change all of your app's left/right layout properties to new start/end equivalents.
If you are targeting your app to Android 4.2 (the app's
targetSdkVersion or minSdkVersion is 17 or higher), then you should
use start and end instead of left and right. For example,
android:paddingLeft should become android:paddingStart.
If you want your app to work with versions earlier than Android 4.2
(the app's targetSdkVersion or minSdkVersion is 16 or less), then you
should add start and end in addition to left and right. For
example, you’d use both android:paddingLeft and android:paddingStart.
RTL layout support feature is supported on Android 4.2(API level 17) or above only . Please Add android:layout_gravity="left/right" in your parent Layout . And also allow android:textAlignment.
Set minSdkVersion=17
Please read http://developer.android.com/reference/android/view/View.html#attr_android:layoutDirection
This will automatically adjust according to the device locale
android:textDirection="locale"

I've made an app, I've tested it and it was fine on my phone. But... when I gave the .apk to someone else whose phone language is RTL the whole layout broke and it messed up everything.
My question is - How can I force my app to use only LTR and disable the auto layout change which breaks my whole app design?
In your manifest file and inside the application tag add these two lines.
<manifest>
<application
.
.
.
android:supportsRtl="false"
tools:replace="android:supportsRtl" //(replace libraries' Rtl support with ours)
>
</application>
</manifest>
Note: (about second line)
Some libraries have support Rtl in their manifest file so if you want to use those libraries you must replace their manifest line of code with yours.
Android 4.2 added full native support for RTL layouts. To take advantage of RTL layout mirroring, simply make the following changes to your app:
Declare in your app manifest that your app supports RTL mirroring.
Specifically, add android:supportsRtl="true" to the
element in your manifest file.
Change all of your app's "left/right" layout properties to new
"start/end" equivalents. If you are targeting your app to Android 4.2
(the app's targetSdkVersion or minSdkVersion is 17 or higher), then
you should use “start” and “end” instead of “left” and “right”. For
example, android:paddingLeft should become android:paddingStart. If
you want your app to work with versions earlier than Android 4.2 (the
app's targetSdkVersion or minSdkVersion is 16 or less), then you
should add “start” and end” in addition to “left” and “right”. For
example, you’d use both android:paddingLeft and android:paddingStart.
For more precise control over your app UI in both LTR and RTL mode, Android 4.2 includes the following new APIs to help manage View components:
android:layoutDirection — attribute for setting the direction of a
component's layout.
android:textDirection — attribute for setting the
direction of a component's text.
android:textAlignment — attribute
for setting the alignment of a component's text.
getLayoutDirectionFromLocale() — method for getting the
Locale-specified direction

Just add the following to the manifest
android:supportsRtl="false"
tools:replace="android:supportsRtl"
Just add something like this in your App Theme Style:
<item name="android:layoutDirection">ltr</item>
or
<item name="android:layoutDirection">rtl</item>
For React Native adding the following line in the manifest file was enough:
// android/app/src/main/AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.kidspodmobileclient">
<uses-permission android:name="android.permission.INTERNET" />
<application
android:supportsRtl="false" // <== add this line here
It would be like the following screenshot:
RN version: 0.68.2
I am developing an app which supports two languages: English("en") and Persian("fa"). I have set android:supportsRtl="false" in AndroidManifest.xml since I need everything to be from left to right. I set margins for all views that I have but for the ones containing a string, it is not working right and it still seems like it is setting the directions from right to left. How can I fix that? I also tried changing the layoutDirection manually to left to right but that did not work either.
You must handle your locale in all activities. Android by default uses the locale of the device to select the appropriate language dependent resources.
Also you must consider project minimum sdk. I recommended to you change it to 16 or higher: minSdkVersion 16
Maybe this link help you.
I set margins for all views that I have but for the ones containing a string, it is not working right
For this for example you must use from android:layout_marginEnd instead of android:layout_marginRight. Also in default create your layout for en locale and then handle and change it by app locale to fa or another locale.
You have to use instead of the right from the end and instead of the left from the start
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="تست"
android:gravity="start"/>
I'm using API 17 and I'm looking for a way to set the whole app to rtl instead of using <android:layoutDirection="rtl"> in every single activity layout.
I had the same problem , all you need to do is just consider all your used parent container (LinearLayout , RelativeLayout , GridView , etc) and set the LayoutDirection to RTL you can approach this way programmtically thanks to ViewCompat class to include api lower than 17.
ViewCompat.setLayoutDirection(yourParentContainer,ViewCompat.LAYOUT_DIRECTION_RTL);
note that there is no need to set the Direction for childviews separately

The easiest and best way
go to the app/res/values/styles and add below code to <style> tag, that you defined its name in android manifest
for example :
<style name"YourMainThemeName" parent="Parent Theme Of Your Choice">
<item name="android:layoutDirection">rtl</item>
</style>
and now go to the app/manifests/AndroidManifest.xml and add below line code to <application> tag :
<application
android:supportsRtl="true"
android:theme="#style/YourMainThemeName">
</application>
now your layout directions is rtl.
I set android:supportsRtl="true" in the <application> tag in AndroidManifest.xml, but I need to force one of the views to be left-to-right nonetheless, even when the language of the interface is Hebrew or Arabic. How can I force a specific view to be LTR in an RTL application?
Specifically, I want to force some linear layout to go left-to-right instead of the default right-to-left even when the language is right-to-left.
Generally gravity="left" is enough to force text to be left-to-right. But it didn't help with the direction of a linear layout. The solution was to add android:layoutDirection="ltr".
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layoutDirection="ltr">
for letf to right all layout content.
To complete the answers, aside from XML, layout direction can also be changed programmatically with ViewCompat.setLayoutDirection(view, LayoutDirection.RTL). This API can be used from API 19 and onwards, so If your min sdk version supports API below 19, an if-check needs to be performed:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
ViewCompat.setLayoutDirection(...)
If you want to force your application to ltr even on rtl languages you don't need layout direction (it works on api>17) you can just set android:supportsRtl to false.
This question already has answers here:
What is the difference between Android margin start/end and right/left?
(3 answers)
Closed 5 years ago.
So I am comfortable with using relative layouts, but whilst getting used to Android Studio I noticed that in my relative layout child views it generated both of the following.
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true
I have checked out the Android docs here, but cannot see a distinction between the two. Certainly swapping one for another in the Android Studio shows no visible difference. Is there one?
It depends on the layout direction. The layout direction can be either left-to-right (start = left, end = right), or right-to-left (vice versa).
By default, the layout direction is based on the locale (left-to-right for languages like English, right-to-left for languages like Arabic), but you can override it with the layoutDirection XML attribute or setLayoutDirection function. e.g.:
android:layoutDirection="ltr"
^ will make alignParentStart equivalent to alignParentLeft on all devices.
android:layoutDirection="rtl"
^ will make alignParentStart equivalent to alignParentRight on all devices. You can also set to "locale" to use the locale or "inherit" to inherit the layout direction from the parent view.
You need to add android:supportsRtl="true" to your AndroidManifest.xml to support right-to-left layouts.
also related: android:textDirection
android:layout_alignParentStart="true"
Aligns the start edge of this view to the start edge of its parent. This is the left edge for LTR (left to right) locales and the right one on RTL (right to left) locale languages like Arabic, Hebrew, Persian etc.
The reason Android Studio also adds
android:layout_alignParentLeft="true"
to your views is to support older platforms that came before 4.2.x Jelly Bean. The Start/End attributes like layout_alignParentStart are only available from API 17 onwards. The newer platforms fallback to Left/Right attributes only if the corresponding Start/End attributes are not found.
In case, your application supports legacy platforms using android:minSdkVersion below level 17 you must always provide Left/Right attributes for your views. Otherwise the project won't compile with an error message like
To support older versions than API 17 (project specifies 7)
you should also add android:layout_alignParentLeft="true"
Also note that your Android application needs to declare its support for RTL locales within your AndroidManifest.xml as well.
<application
...
android:supportsRtl="true"
/>
These "xxxStart", "xxxEnd" attribute is to support RTL(Right to Left) layout in some locales.
Such as
android:paddingStart
android:paddingEnd
android:layout_marginStart
android:layout_marginEnd
...
You can see more here about it.
In normal(left to right) layout, "xxxStart" means "xxxLeft" and "xxxEnd" means "xxxRight".But in Right to Left layout, "xxxStart" means "xxxRight" and "xxxEnd" means "xxxLeft".
But RTL is only supported on sdk 17 and higher.
To support lower sdk, you can use "android:layout_marginStart" along with "android:layout_marginLeft". At the lower sdk devices, "android:layout_marginLeft" will be used.
