How To Disable/ Lock One Page In Viewpager?

I want lock / disable one particular page(fragment) in viewpager. According to scenario for some people only able to access that page. How restrict swiping to that page. I disabl

Solution 1:

I written this in pager adapter it works.

@Override
publicintgetCount() {
  if(!isAccess) {
    return3;
  } else {
    return4;
  }
}

Solution 2:

Use this

viewPager.setOnPageChangeListener(new OnPageChangeListener() {
publicvoidonPageScrollStateChanged(int state) {}
publicvoidonPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}

publicvoidonPageSelected(int position) {
    if (position == 3)
   {
     // show dialog that you are not allowed
      viewPager.setSelected(2);
   }  
}
});

Hope this helped you

You can also use

viewPager.addOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

// optional @Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { }

// optional @Override
public void onPageSelected(int position) { }

// optional @Override
public void onPageScrollStateChanged(int state) { }
});

Solution 3:

This is also the solution without using the deprecated method (setOnPageChangeListener).

        viewPager.addOnPageChangeListener(newViewPager.SimpleOnPageChangeListener() {
        @OverridepublicvoidonPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
            super.onPageScrolled(position, positionOffset, positionOffsetPixels);
        }

        @OverridepublicvoidonPageSelected(int position) {
            super.onPageSelected(position);

            if(position == 3) {
                //To disable specific tab and set the previuos tab
                viewPager.setCurrentItem(2); //We cannot provide the position in setSelected(boolean) now. This was missed in above solution
            }
        }

        @OverridepublicvoidonPageScrollStateChanged(int state) {
            super.onPageScrollStateChanged(state);
        }
    });    

Solution 4:

Initialize the first tab position

int currentTab = 0;

then make listener for viewPager

viewPager.addOnPageChangeListener(newViewPager.OnPageChangeListener() {
            @OverridepublicvoidonPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

            }

            @OverridepublicvoidonPageSelected(int position) {
                //4 is the position of the tab we want to disableif (position == 4) {
                    if (currentTab < 4) {
                        // swipe from left to right
                        viewPager.setCurrentItem(5);
                        currentTab = 5;
                    } else {
                        // swipe from right to left 
                        viewPager.setCurrentItem(3);
                        currentTab = 3;
                    }
                } else {
                    currentTab = position;
                }
            }

            @OverridepublicvoidonPageScrollStateChanged(int state) {

            }
        });
