How to define a caret color for text input in React Native for Android?

I need to customize a caret color in the specific text input.
screenshot with needed element
I've found three options to do this but none works for me.
Adding to style.xml the next code:
<item name="colorControlActivated">#color/white</item>
But it works for all control items like Switch, other TextInputs etc. And I need to change color only for single TextInput.
I've tried to specify selectionColor, but it works only for cursor and the background of the selected text, not caret.
I've tried to add the drawable xml file and add to style.xml the next thing:
<item name="android:editTextStyle">#style/myEditText</item>
<style name="myEditText" parent="#android:style/Widget.Holo.Light.EditText">
<item name="android:textCursorDrawable">#drawable/color_cursor</item>
</style>
But it is not work at all. Used this answer like template

How to change to text colour of the Cut/Copy/Paste popup menu

I have the following in my styles.xml
<style name="dialog_style" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">#ffaaaa00</item>
<item name="android:background">#ff444400</item>
<item name="android:textColorPrimary">#ffa25600</item>
</style>
(The horrible colours are for testing only!)
This gives the following
What I want is a dark/black background but when I do that, the text is unreadable.
Q: How do I change the text colour of "Cut", "Copy"...?

I think it's a little bit better solution than user3247782's,
<style name="CustomAlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
...
<item name="android:popupBackground">#android:color/transparent</item>
</style>

You can change them by following style names:
<item name="colorAccent">#color/twoCuteSelectionHandlersColor</item>
<item name="android:textColorHighlight">#color/selectionColor</item>
Also you can set highlight color directly for pacific EditText using android:textColorHighlight attribute in xml layout or programmatically:
et.setHighlightColor(color);
For context menu you need create your own context menu. check this question for how disabling default context menu and implementing custom menu.

This isn't really an answer. The black-on-black edit menu is only generated from an EditText contained in an AlertDialog. The same code in a Fragment gives black-on-white.
So I "solved" my problem by converting the AlertDialog into a Fragment.
The original question, though, is still unanswered.

Alert Dialog and Popup Menu generaly take the color of #ColorAccent as the background. So try changing the colorAccent or just inflate a custom xml with the specifications you want.

Just change the parent of it from Theme.Material.Light to Theme.Material .
It will make the text white, there.

I fixed it by setting a background color with opacity in the style of the alertdialog
In styles.xml
<style name="AppCompatAlertDialogStyle">
...
<item name="android:background">#color/black_overlay</item>
...
</style>
In colors.xml
<color name="black_overlay">#66000000</color>

If you use MaterialAlertDialogBuilder then you can define background color through colorSurface attribute.
Then in styles you can just set background to transparent.
android:background="#android:color/transparent"
Dialog will use the one define in colorSurface and "copy/paste" will use default system colors (e.g. white).

What property controls Spinner dropdown background?

I have a custom theme created with this generator. It has a custom style for Spinners which I don't like. I want to change the background drawable but I can't seem to figure out which property controls this.
This is what the themed version looks like
And here is what it will look like when using the Holo.Light theme.
Notice the dark gray lines around the dropdown list in the first (themed) image. This is what I want to get rid of. What property controls this? I want them to match the default.
Also, what controls the vertical aligment of the dropdown list? As you can see, it is overlapping with the Spinner in the first image (the line under it isn't visible as it is in the second image).

The attribute you want is android:popupBackground on the Spinner element.
If you look closely, the holo popup also overlaps the spinner some, but there is a bunch of padding for the drop shadow, so it looks good.
However, you can use android:dropDownVerticalOffset on the Spinner element to adjust it.

We came across the same issue. It has to do with the Android Holo theme generator.
Here are the lines that you should remove from your Theme.xml file...
<item name="android:spinnerStyle">#style/SpinnerCustom</item>
<item name="android:spinnerDropDownItemStyle">#style/SpinnerDropDownItemCustom</item>
<item name="android:popupMenuStyle">#style/PopupMenu.Custom</item>
<item name="android:dropDownListViewStyle">#style/DropDownListView.Custom</item>
<item name="android:actionDropDownStyle">#style/DropDownNav.Custom</item>
...by removing these, we now have the standard Holo.Light theme on the spinner dropdowns.

You need to change the parent of spinnertheme to android:Widget.Holo.Light.Spinner
<style name="SpinnerTHEME" parent="android:Widget.Holo.Light.Spinner">

<style name="spinner_style" parent="android:Widget.Holo.Light.Spinner">
<item name="android:paddingLeft">#dimen/ten_dp</item>
<item name="android:paddingRight">#dimen/ten_dp</item>
</style>

TextView style in dialog, can not see text in froyo but can see in ics

I have a dialog box that I create to display messages in android. It basically contains a text view in a scrollview like this
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/about_msg"
android:text="#string/about_msg"
android:autoLink="web"
android:padding="10dip"
style="#style/DialogTextSmall" />
</ScrollView>
As you can see I have applied a style to TextView the style looks like this
<style name="DialogTextSmall">
<item name="android:textSize">#dimen/text_size_small</item>
</style>
The application theme set is like this
<style name="AppTheme" parent="android:Theme.Light">
The Problem:
On ICS api-15 it shows fine black text on white background of TextView.
The problem is When I show dialogbox in Froyo its the text does'nt seem to show even though it seems to have taken space - My guess is the color of text is same as background (greyish black)
I know I can quick fix by hard-coding black background and white text, but Is it not possible to have the default colors of platform for the text color and background of the TextView to appear, without me having to hardcode them ?

You can inherit a parent style and then only change the values you want to change. Try changing your XML to this:
<style name="DialogTextSmall" parent="#android:style/Widget.TextView>
<item name="android:textSize">#dimen/text_size_small</item>
</style>
The list of styles you can inherit can be found in the AOSP source on Github here.
EIDT:
By default text views have black text and transparent background, so you will need to set one or the other if the background behind the text view (which, again, is transparent) is black.

Inheritance from Textview style did not really help. It is a little quirky problem and here is one way to do it
http://blog.andromo.com/2011/fixing-text-colours-on-an-alertdialog-when-using-theme-light/
In my case I did it another way
Solved it for theme I inherited it from default android theme
<style name="Theme" parent="android:Theme"></style>
<style name="Theme.AppTheme" parent="#android:style/Theme.Light"/>
and
<style name="DialogTextSmall">
<item name="android:textSize">#dimen/text_size_small</item>
<item name="android:textColor">#android:color/white</item>
</style>
This way for all platforms , froyo, gingerbread and above, the dialog boxes are black and text is white on them

Changing android search dialog text color

I styled my App using a theme as described here.
<style name="MyThemeNameHere" parent="#android:style/Theme.NoTitleBar">
<item name="android:windowBackground">#drawable/background</item>
<item name="android:textColor">#eee</item>
<style>
It works like a charm in most of the App. The background is pretty dark while the text color is bright and text looks good and is easy to read.
Now in the search dialog that android creates for me the background is white, but the text color picks up my style and gets very bright and thus extremely hard to read. I tried also setting android:background to a dark color - This fixed the problem in the search dialog, but caused all textview, etc to get a dark background rather than transparent.
I want to either set the the color or the background only on the search dialog. How do I do this?

As pointed out by Mark Philip the solution can be found in this question:
Android Styling/Theming of just Search Dialog
Basically it should be styled like so
<style name="master" paret="#android:style/Theme.NoTitleBar">
<item name="android:textColorPrimary">#EEEEEE</item>
<item name="android:textColorSecondary">#EEEEEE</item>
<item name="android:textColorTertiary">#EEEEEE</item>
</style>
The root cause was that I styled the android:textColor which should never be styled.
