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

I tried all the answers above, but I did not get a complete solution. If you want do disable only the PASTE option, you can try this:

override fun getSelectionStart(): Int {
    for (element in Thread.currentThread().stackTrace) {
        if (element.methodName == "canPaste") {
            return -1
        }
    }
    return super.getSelectionStart()
}

It is just a hack, but I didn't find anything better.

if you want to disable the menu and cursor completely, you can try following class instead of your EditText:

class MaskedCodeEditTextView : EditText {
    constructor(context: Context) : super(context) {
        init()
        blockContextMenu()
    }

    constructor(context: Context, attrs: AttributeSet?) : super(context, attrs) {
        init()
        blockContextMenu()
    }

    constructor(context: Context, attrs: AttributeSet?, defStyle: Int) : super(
        context,
        attrs,
        defStyle
    ) {
        init()
        blockContextMenu()
    }

    override fun getSelectionStart(): Int {
        for (element in Thread.currentThread().stackTrace) {
            if (element.methodName == "canPaste") {
                return -1
            }
        }
        return super.getSelectionStart()
    }

    private fun setInsertionDisabled() {
        try {
            val editorField = TextView::class.java.getDeclaredField("mEditor")
            editorField.isAccessible = true
            val editorObject = editorField[this]
            val editorClass = Class.forName("android.widget.Editor")
            val mInsertionControllerEnabledField =
                editorClass.getDeclaredField("mInsertionControllerEnabled")
            mInsertionControllerEnabledField.isAccessible = true
            mInsertionControllerEnabledField[editorObject] = false
        } catch (ignored: Exception) {
            // ignore exception here
        }
    }

    private fun blockContextMenu() {
        this.customSelectionActionModeCallback = ActionModeCallbackInterceptor()
        this.isLongClickable = false
        setOnClickListener { v: View? ->
            v?.let {
                if(!it.isFocused) {
                    requestFocus()
                } else {
                    clearFocus()
                    requestFocus()
                }
            }
        }
    }

    override fun isSuggestionsEnabled(): Boolean {
        return false
    }

    private fun init() {
        this.customSelectionActionModeCallback = ActionModeCallbackInterceptor()
        this.isLongClickable = false
    }

    override fun onTouchEvent(event: MotionEvent): Boolean {
        if (event.action == MotionEvent.ACTION_DOWN) {
            setInsertionDisabled()
        }
        return super.onTouchEvent(event)
    }

    private inner class ActionModeCallbackInterceptor : ActionMode.Callback {
        override fun onCreateActionMode(mode: ActionMode, menu: Menu): Boolean {
            return false
        }

        override fun onPrepareActionMode(mode: ActionMode, menu: Menu): Boolean {
            return false
        }

        override fun onActionItemClicked(mode: ActionMode, item: MenuItem): Boolean {
            return false
        }

        override fun onDestroyActionMode(mode: ActionMode) {}
    }
}
