LockableViewPager.java

public class LockableViewPager extends ViewPager {
  private static final boolean DEFAULT_LOCK_STATE = false;

  private boolean locked;

  public LockableViewPager(Context context) {
    this(context, null);
  }

  public LockableViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
    init(context, attrs);
  }

  private void init(Context context, AttributeSet attrs) {
    final TypedArray typedArray =
        context.obtainStyledAttributes(attrs, R.styleable.LockableViewPager);
    locked = typedArray.getBoolean(R.styleable.LockableViewPager_locked, DEFAULT_LOCK_STATE);
    typedArray.recycle();
  }

  @Override public boolean onTouchEvent(MotionEvent event) {
    return locked || super.onTouchEvent(event);
  }

  @Override public boolean onInterceptTouchEvent(MotionEvent event) {
    return locked || super.onInterceptTouchEvent(event);
  }

  public boolean isLocked() {
    return locked;
  }

  public void setLocked(boolean locked) {
    this.locked = locked;
  }
}

if locked is true，the view inside viewpager will nerver get event any more...
You should try: !locked && super.onInterceptTouchEvent(event)
