How to disable viewpager?

Question

Android

The situation is this, there are windows in the viewPager and in one of these windows you can run a fragment, and at the moment when the fragment is on the screen I need to disable the ability to scroll through the screens in the viewPager, how can I do this? Maybe there is some method in the viewPager that turns it off?

There is no easy way.
To prevent swipe from working, you need your own sub-class for ViewPager, with the following logic:

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class TabItems extends ViewPager {

  public boolean mIsEnabled;
  
  public TabItems(Context context) {
    super(context);
    // TODO Auto-generated constructor stub
    init();
  }
  public TabItems(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
  }
  
  void init() {
    mIsEnabled = true;
  }
  
    @Override
    public boolean onTouchEvent(MotionEvent event) {
    	if (mIsEnabled) {
    		return super.onTouchEvent(event);
    	} else {
    		return false;
    	}
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
    	if (mIsEnabled) {
    		return super.onInterceptTouchEvent(event);
    	} else {
    		return false;
    	}
    }
}

In the case of TabLayout, so that clicking on the tabs themselves also does not work, you must also:

LinearLayout tabStrip = ((LinearLayout)tabLayout1.getChildAt(0));
        for (int i = 0; i < tabStrip.getChildCount(); i++) {
            tabStrip.getChildAt(i).setEnabled(false);
            tabStrip.getChildAt(i).setAlpha(130);
        }
