Answer 1

onFling()方法必须返回一个布尔值：

public MyGallery(PhotoAlbumDetailActivity context) {
    super(context);
    this.context = context;
    this.setFadingEdgeLength(0);
    //this.setSpacing(10);
}

public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
    Log.i("test", "onFling()");
    return super.onFling(e1, e2, velocityX, velocityY);
}
