SwipeRefreshLayout + ViewPager, limit horizontal scroll only?

I've implemented SwipeRefreshLayout and ViewPager in my app but there is a big trouble: whenever I'm going to swipe left / right to switch between pages the scrolling is too sensitive. A little swipe down will trigger the SwipeRefreshLayout refresh too.

I want to set a limit to when horizontal swipe starts, then force horizontal only until swiping is over. In other words, I want to cancel vertical swipping when finger is moving horizontally.

This problem only occurs on ViewPager, if I swipe down and SwipeRefreshLayout refresh function is triggered (the bar is shown) and then I move my finger horizontally, it still only allows vertical swipes.

I've tried to extend the ViewPager class but it isn't working at all:

public class CustomViewPager extends ViewPager {

    public CustomViewPager(Context ctx, AttributeSet attrs) {
        super(ctx, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        boolean in = super.onInterceptTouchEvent(ev);
        if (in) {
            getParent().requestDisallowInterceptTouchEvent(true);
            this.requestDisallowInterceptTouchEvent(true);
        }
        return false;
    }

}

Layout xml:

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/viewTopic"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <com.myapp.listloader.foundation.CustomViewPager
        android:id="@+id/topicViewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</android.support.v4.widget.SwipeRefreshLayout>

any help would be appreciated, thanks

Solution 1:

I am not sure if you still have this issue but Google I/O app iosched solves this problem thusly:

    viewPager.addOnPageChangeListener( new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled( int position, float v, int i1 ) {
        }

        @Override
        public void onPageSelected( int position ) {
        }

        @Override
        public void onPageScrollStateChanged( int state ) {
            enableDisableSwipeRefresh( state == ViewPager.SCROLL_STATE_IDLE );
        }
    } );


private void enableDisableSwipeRefresh(boolean enable) {
    if (swipeContainer != null) {
            swipeContainer.setEnabled(enable);
    }
}

I have used the same and works quite well.

EDIT: Use addOnPageChangeListener() instead of setOnPageChangeListener().

Solution 2:

Solved very simply without extending anything

mPager.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        mLayout.setEnabled(false);
        switch (event.getAction()) {
            case MotionEvent.ACTION_UP:
                mLayout.setEnabled(true);
                break;
        }
        return false;
    }
});

work like a charm
