Disable EditText context menu

Question

I am making a vertical EditText for traditional Mongolian. I have successfully implemented it by embedding a slightly modified EditText inside of a

This is a hard problem. I've spent hours and hours researching and testing in my Android Studio 3.4.2.

I propose 3 steps:

a) the setCustomSelectionActionModeCallback "solution" in the original question But it keeps showing the select handles (red drop under the cursor) and "Clipboard + Select All" popup, when you click in the red drop.

b) Create a empty image for select handles. I've created a file called ic_empty.xml under res/drawable.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
</shape>

c) I've created a style in style.xml for all EditTexts.

Under main theme

 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        ...
        <item name="android:editTextStyle">@style/TStyle</item>
        ....
 </style>

So you can define you style associating an empty image for lef, middle, and right select handles:

   <style name="TStyle" parent="@android:style/Widget.EditText" >
        <item name="android:textSelectHandle">@drawable/ic_empty</item>
        <item name="android:textSelectHandleLeft">@drawable/ic_empty</item>
        <item name="android:textSelectHandleRight">@drawable/ic_empty</item>
    </style>

If the target is from API 23 one can use setTextAppearance for attach a style in a text inside a EditText. However, the above solution works always

The only remaining problem is that I can rid of double click effect. It selects a word in the text, with pink background. However, it is relatively harmless, but awkward, because it does not require user interaction.

A trick that can be done it's set the highlight color transparent.

EditT.setHighlightColor(Color.TRANSPARENT)  // EditT is a EditText
