Question

I am using cover flow in my project and while display of cover flow on button click i am showing popup.

(Coverflow in android is the style to display images in line which is scrolled on touch as we generally see in media player and can be selected ;It’s based on the Android Gallery widget and is used in the same way, with a ViewAdapter. My main aim when coding this coverflow widget was to create an easily re-usable component using the standard Android 2D libraries

scroll/navigate on touch i.e i want to disable coverflow untill popup

          coverFlow.clearFocus();
          Popup.setFocusable(true);

          coverFlow.setEnabled(false);
          coverFlow.setSelected(false);

I don’t know what source code of CoverFlow you are using. But you can custom it.

Extend the CoverFlow (which already extends Gallery, i think), override the onTouchEvent and onInterceptTouchEvent methods with return false if you don’t want the CoverFlow scroll, and add the method to set this attribute.

The code maybe looks like :

@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 setScrollEnabled(boolean enabled) {
    this.enabled = enabled;
}

And then you can set the CoverFlow scroll or not by using setScrollEnabled method
