How to change the width of cursor in React native TextInput? - react-native

I want to make the blinking cursor thin in TextInput, how to do that? The normal width is like 3px, I want it to have 1px.

For android you can follow this steps:
step 1: Create editext_cursor.xml and place it under res->drawable directory.
android/app/src/main/res/drawable/editext_cursor.xml
step 2: inside editext_cursor.xml paste this:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<size android:width="1dip" />
<solid android:color="#010101" />
</shape>
and here you can change the width to whatever you want.
step 3: add that line to android/app/src/main/res/values/styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="android:textColor">#000000</item>
<item name="android:textCursorDrawable">#drawable/editext_cursor</item> <-- add this
</style>
</resources>
step 4: rebuild your app

How to tap on the three dot menu (more options) in the actionbar on Android using Detox?

How to tap on the three dot menu (more options) in the actionbar on Android using Detox?
I followed this SO answer, https://stackoverflow.com/a/65736139/3970346
Since this is a NativeScript app the steps are,
Create a ids.xml file under app/App_Resources/Android/src/main/res/values folder,
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item type="id" name="overflowActionButton"/>
</resources>
Then in the styles.xml in the same directory add,
<style name="Widget.ActionButton.Overflow" parent="Widget.AppCompat.ActionButton.Overflow">
<item name="android:id">#id/overflowActionButton</item>
<item name="android:contentDescription">"overflowActionButton"</item>
<item name="android:tint">#color/white</item>
</style>
Finally set the style on the AppThemeBase like this,
<!-- theme to use AFTER launch screen is loaded-->
<style name="AppThemeBase" parent="Theme.AppCompat.Light.NoActionBar">
<item name="toolbarStyle">#style/NativeScriptToolbarStyle</item>
<item name="colorPrimary">#color/ns_primary</item>
<item name="colorPrimaryDark">#color/ns_primaryDark</item>
<item name="colorAccent">#color/ns_accent</item>
<!-- the line below -->
<item name="actionOverflowButtonStyle">#style/Widget.ActionButton.Overflow</item>
</style>
After this you can tap on the overflow menu in Detox like this,
await element(by.label('overflowActionButton')).tap();

Change the background color of textInput highlight (autocomplete) on react-native

How can I change this background color of TextInput when it got highlight from the autoCompleteType that already exists on react native?
like on this image
To customize this autofill bg color, you have to set this at android level.
Create a xml file with the name of your choice, for example autofill_highlight.xml in android/app/src/main/res/drawable
Put this code inside :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#android:color/transparent" />
</shape>
Here, the color set is transparent ("#android:color/transparent"), replace it with your color.
In android/app/src/main/res/values/styles.xml, add this line to your app theme (make sure to provide your own file name if you don't call it autofill_highlight like in my example)
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- ... your other theme customization ... -->
<!-- ADD THE FOLLOWING LINE -->
<item name="android:autofilledHighlight">#drawable/autofill_highlight</item>
</style>
</resources>
Rebuild your application :)

How to change height of Xamarin Shell.TitleView?

you could try to add android:actionBarSize to your styles.xml
<?xml version="1.0" encoding="utf-8" ?>
<resources>
<style name="MainTheme" parent="MainTheme.Base">
</style>
<!-- Base theme applied no matter what API -->

...
<!-- ********* CHECK HERE ********* -->
<item name="android:actionBarSize">80dp</item>
...

Naviagation Page is not setting BarBackgroundColor in XAML

Below is the code for XAML for customNavigation in Xamarin. The bar color is not set but Bar text color is set. And this is only happening in Android, iOS works fine.
<NavigationPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="DSXMobile.Views.CustomNavigationView"
BarBackgroundColor="Red"
BarTextColor="Black">
</NavigationPage>
Can anyone please help me ?
This is a known issue,
From Xamarin forums https://forums.xamarin.com/discussion/88569/barbackgroundcolor-refusing-to-get-set-on-android-but-bartextcolor-is-fine
"If you are using FormsAppCompatActivity
This is a bug in XF if you're using the FormsAppCompatActivity.
The workaround is to set android:background in your applications' layout file used for FormsAppCompatActivity.ToolbarResource.
Set this value to anything, example: android:background="#00000000"
Then XF will style it with whatever colour is in your XAML style later.
Really dumb bug, hope it gets sorted soon."

Like the other answer says its a bug but i don't know if it should be called a bug because android is doing what it does picking the theme that you have assigned to its activity in your styles.xml now what you can do is make that same change in your styles.xml my theme something like this :
<?xml version="1.0" encoding="utf-8" ?>
<resources>
<style name="MyTheme" parent="MyTheme.Base">
</style>
<style name="DrawerArrowStyle"
parent="#style/Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">#FFFFFF</item>
</style>
<style name="MyTheme.Base"
parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">#003399</item>
<item name="colorPrimaryDark">#003399</item>
<item name="colorControlHighlight">#003399</item>
<item name="colorAccent">#012348</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
</style>
</resources>
Changing the colors in here will change it there aswell for eg ColorPrimary is your toolbar color
