How to disable or enable viewpager swiping in android

Question

What i am trying to do: I am trying to Enable/disable swiping in pager programatically when the program is running

Ex: When on the flow if i check for a condition and if it returns true enable swiping, and if condition returns false disable swiping.

---

Solution i am using is this one

public class CustomViewPager extends ViewPager {  private boolean enabled;  public CustomViewPager(Context context, AttributeSet attrs) {     super(context, attrs);     this.enabled = true; }  @Override public boolean onTouchEvent(MotionEvent event) {     if (this.enabled) {         return super.onTouchEvent(event);     }      return false; }  @Override public boolean onInterceptTouchEvent(MotionEvent event) {     if (this.enabled) {         return super.onInterceptTouchEvent(event);     }      return false; }  public void setPagingEnabled(boolean enabled) {     this.enabled = enabled; } } 

Then select this instead of the builtin viewpager in XML

<mypackage.CustomViewPager  android:id="@+id/myViewPager"  android:layout_height="match_parent"  android:layout_width="match_parent" /> 

You just need to call the "setPagingEnabled" method with "false" and users won't be able to swipe to paginate.

Problem with above methodology: i cannot set the property on the flow, I:e .... I either can enable swiping or disable swiping. But i cannot do this based on condition

Question:

1. Can i achieve my goal in some-other way, if so what is it ?
2. Or is this not possible ?

Best solution for me. -First, you create a class like this:

public class CustomViewPager extends ViewPager {   private Boolean disable = false;   public CustomViewPager(Context context) {       super(context);   }   public CustomViewPager(Context context, AttributeSet attrs){       super(context,attrs);   }   @Override   public boolean onInterceptTouchEvent(MotionEvent event) {      return !disable && super.onInterceptTouchEvent(event);   }    @Override   public boolean onTouchEvent(MotionEvent event) {      return !disable && super.onTouchEvent(event);   }    public void disableScroll(Boolean disable){       //When disable = true not work the scroll and when disble = false work the scroll       this.disable = disable;   } } 

-Then change this in your layout:<android.support.v4.view.ViewPager for this<com.mypackage.CustomViewPager

-Finally, you can disable it:view_pager.disableScroll(true); or enable it: view_pager.disableScroll(false);

I hope that this help you :)
