I have implemented an Overlay view... currently the view is detachable by edge swiping from left to right (like paging). I would like to prevent this. How can I do that?
I have tried the method recommended in How do disable paging by swiping with finger in ViewPager but still be able to swipe programmatically? to disable paging by swiping with finger in ViewPager. However, it didn't help my case.
This is how I inflate my view,
private void initView() {
if (null == mInflater) {
mInflater = (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
if (null == mscreenView) {
mscreenView = mInflater.inflate(R.layout.view_screen, null);
}
}
My view_screen.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
