After I used onTouchlistener then onclick listener stops working in recyclerview

I am using dragging feature for recycler view by using ItemTouch helper.
Dragging is working fine but I am unable to use onclick listener on the same view.
Below is my code:
holder.mainLayout.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
mCommunicator.onStartDrag(holder);
return false;
}
});
holder.mainLayout.setOnClickListener(v -> {
//LogManager.v(LOG_TAG,"touch:"+blnOnTouch);
holder.checkBox.performClick();
});
Please suggest me for this issue. Thanks in advance.

public class OnTouchListner implements OnTouchListener{
#Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction()==MotionEvent.ACTION_DOWN)
{
businessResultListView.smoothScrollBy(0, 0);
return true;
}
return false;

This may help you....
parentScrollView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
Log.v(TAG,"PARENT TOUCH");
findViewById(R.id.child_scroll).getParent().requestDisallowInterceptTouchEvent(false);
return false;
}
});
childScrollView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event)
{
Log.v(TAG,"CHILD TOUCH");
// Disallow the touch request for parent scroll on touch of child view
v.getParent().requestDisallowInterceptTouchEvent(true);
return false;
}
});
In your case 'parentScrollView' is your scrollView while childScrollView is your Linearlayout/EditText

Use yourEditTextView.setMovementMethod(new ScrollingMovementMethod());

Is there anyway to remove an onTouchListener from a view object?

I have an on touch listener for a webview, but it has a bad effect on the functionality of the webview, so I am wondering if there is anyway to removed the on touch listener after the initial interaction?

webView.setOnTouchListener(null);

So in you activity you would set your overridden onTouchListener:
mWebView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
v.setOnTouchListener(mWebView.mOnTouchListener);
return false;
}
});
And you would have to make a new class, extending WebView. And within it you would define an OnTouchListener.
public final OnTouchListener mOnTouchListener = new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent rawEvent) {
return false;
}
};
Setting the ontouchlistener to null doesn't reset it to the default definition. You still have to provide an actual listener.

I was looking for help online and got to this post.
When I did
myView.setOnTouchListener(null);
my myView stopped responding to the onTouch.
