Question

I have a ViewPager which instantiates a View. I’d like to disable both the scrolling of the viewpager and the child buttons momentarily while a search result is returned to the view. I’ve calling viewPager.setEnabled(false) but this doesn’t disable it.

Anyone got any ideas?

A simple solution is to create your own subclass of ViewPager that has a private boolean flag, isPagingEnabled. Then override the onTouchEvent and onInterceptTouchEvent methods. If isPagingEnabled equals true invoke the super method, otherwise return.

public class CustomViewPager extends ViewPager {

    private boolean isPagingEnabled = true;

    public CustomViewPager(Context context) {
        super(context);
    }

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

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return this.isPagingEnabled && super.onTouchEvent(event);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        return this.isPagingEnabled && super.onInterceptTouchEvent(event);
    }

    public void setPagingEnabled(boolean b) {
        this.isPagingEnabled = b;
    }
}

Then in your Layout.XML file replace any <com.android.support.V4.ViewPager> tags with <com.yourpackage.CustomViewPager> tags.
