SampleDisableCopyPaste

In this sample i am handling disable copy paste in EditText as well as desable clipboard. This is working fine for all devices.

Normally you achive this functionlity with this code

    android:importantForAutofill="no"
    android:longClickable="false"

But in some of device not working

Please add some more code

Note:

customInsertionActionModeCallback method added in android api level 23 and customSelectionActionModeCallback introduce with android api 11

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
        this.customInsertionActionModeCallback= object : 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?) {
            }
        }
    }
    this.customSelectionActionModeCallback = object : 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?) {
        }

    }

Handle imeoptions in Samsung device

 this@SecureInputView.privateImeOptions="disableToolbar=true"

Handle Chinese devices like RedMi

  override fun onTouchEvent(event: MotionEvent): Boolean {
    if (event.action==MotionEvent.ACTION_DOWN){
        setInsertionDisabled()
    }
    return super.onTouchEvent(event)
}
private fun setInsertionDisabled() {
    try {
        val field= TextView::class.java.getDeclaredField("mEditor")
        field.isAccessible=true
        val obj=field.get(this)
        @SuppressLint("PrivateApi") val editorClass = Class.forName("android.widget.Editor")
        val classfields=editorClass.getDeclaredField("mInsertionControllerEnabled")
        classfields.isAccessible=true
        classfields.set(obj,false)
    }catch (e:Exception){e.printStackTrace()}
