Android - How to disable ViewPager from swiping in one direction

To disable swiping in a specific direction in a ViewPager in Android, you can create a custom ViewPager class and override its onTouchEvent method to intercept touch events and prevent them from being passed to the ViewPager for a specific direction.

Here's an example in Kotlin:

import android.content.Context import android.util.AttributeSet import android.view.MotionEvent import androidx.viewpager.widget.ViewPager class CustomViewPager(context: Context, attrs: AttributeSet) : ViewPager(context, attrs) { private var isSwipeEnabled = true private var swipeDirection = SwipeDirection.ALL enum class SwipeDirection { ALL, LEFT, RIGHT } fun setSwipeEnabled(enabled: Boolean) { isSwipeEnabled = enabled } fun setSwipeDirection(direction: SwipeDirection) { swipeDirection = direction } override fun onTouchEvent(ev: MotionEvent?): Boolean { if (isSwipeEnabled) { return super.onTouchEvent(ev) } return false } override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean { if (isSwipeEnabled) { return super.onInterceptTouchEvent(ev) } // Disable swiping in the specified direction if (swipeDirection == SwipeDirection.LEFT) { return ev?.action != MotionEvent.ACTION_MOVE && super.onInterceptTouchEvent(ev) } else if (swipeDirection == SwipeDirection.RIGHT) { return ev?.action != MotionEvent.ACTION_MOVE && super.onInterceptTouchEvent(ev) } return false } } 

In this example, the CustomViewPager class extends the standard ViewPager. You can set whether swiping is enabled or disabled using the setSwipeEnabled method. Additionally, you can set the allowed swipe direction using the setSwipeDirection method.

Use this custom ViewPager in your XML layout file:

<com.example.yourpackage.CustomViewPager android:id="@+id/viewPager" android:layout_width="match_parent" android:layout_height="match_parent"/> 

Then, in your code, find the ViewPager and configure it:

val viewPager: CustomViewPager = findViewById(R.id.viewPager) viewPager.setSwipeEnabled(false) // Disable swiping viewPager.setSwipeDirection(CustomViewPager.SwipeDirection.RIGHT) // Allow only right swiping 

Adjust the package name (com.example.yourpackage) accordingly. Now, the CustomViewPager will allow or disable swiping based on your configuration.

Examples

  1. "Disable ViewPager swipe left Android"

    • Code:
      // In your ViewPager setup viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { // Disable swipe to the left viewPager.beginFakeDrag(); } @Override public void onPageSelected(int position) { } @Override public void onPageScrollStateChanged(int state) { } }); 
    • Description: Uses beginFakeDrag to disable swipe to the left in the ViewPager during the onPageScrolled callback.
  2. "Android ViewPager disable swipe right"

    • Code:
      // In your ViewPager setup viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { // Disable swipe to the right viewPager.endFakeDrag(); } @Override public void onPageSelected(int position) { } @Override public void onPageScrollStateChanged(int state) { } }); 
    • Description: Utilizes endFakeDrag to disable swipe to the right in the ViewPager during the onPageScrolled callback.
  3. "How to disable ViewPager swipe in one direction Android"

    • Code:
      // In your ViewPager setup viewPager.setAllowedSwipeDirection(AllowedSwipeDirection.LEFT); 
    • Description: Uses a custom method (setAllowedSwipeDirection) to selectively disable swipe in a specified direction (e.g., left).
  4. "Android ViewPager disable swipe up"

    • Code:
      // In your ViewPager setup viewPager.setAllowedSwipeDirection(AllowedSwipeDirection.UP); 
    • Description: Extends the approach to selectively disable swipe in a particular direction (e.g., up) using a custom method.
  5. "Disable ViewPager swipe down Android"

    • Code:
      // In your ViewPager setup viewPager.setAllowedSwipeDirection(AllowedSwipeDirection.DOWN); 
    • Description: Sets the allowed swipe direction to down using a custom method, preventing swipe in the specified direction.
  6. "Android ViewPager disable horizontal swipe"

    • Code:
      // In your ViewPager setup viewPager.setAllowedSwipeDirection(AllowedSwipeDirection.NONE); 
    • Description: Disables horizontal swipe completely by setting the allowed swipe direction to none using a custom method.
  7. "How to disable ViewPager swipe vertically Android"

    • Code:
      // In your ViewPager setup viewPager.setAllowedSwipeDirection(AllowedSwipeDirection.VERTICAL); 
    • Description: Restricts swipe to vertical only by setting the allowed swipe direction to vertical using a custom method.
  8. "Android ViewPager disable swipe left right"

    • Code:
      // In your ViewPager setup viewPager.setAllowedSwipeDirection(AllowedSwipeDirection.VERTICAL); 
    • Description: Modifies the allowed swipe direction to vertical, effectively disabling swipe left and right in the ViewPager.
  9. "Disable ViewPager swipe programmatically Android"

    • Code:
      // In your ViewPager setup viewPager.setPagingEnabled(false); 
    • Description: Uses a custom method (setPagingEnabled) to programmatically disable swipe in both directions for the ViewPager.
  10. "Android ViewPager disable swipe during animation"

    • Code:
      // In your ViewPager setup viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { // Disable swipe during animation viewPager.beginFakeDrag(); } @Override public void onPageSelected(int position) { } @Override public void onPageScrollStateChanged(int state) { if (state == ViewPager.SCROLL_STATE_IDLE) { // Enable swipe after animation viewPager.endFakeDrag(); } } }); 
    • Description: Temporarily disables swipe during animation and re-enables it when the animation is complete using beginFakeDrag and endFakeDrag.
