Android的：子类库不通过onKeyDown事件滚动 [英] Android: Sub-class Gallery doesn't scroll by onKeyDown event

问题描述

我有一个子类图库部件，我定制了onFling方法，否则一切都应该是一样的原始画廊部件。

I have a sub-classed Gallery widget which I customized its onFling method, otherwise everything should be the same as the original Gallery widget.

和我试图动画留下了滚动或向右使用：

And I am trying to animate its scrolling left or right by using:

gallery.onKeyDown(KeyEvent.KEYCODE_DPAD_LEFT, new KeyEvent(0, 0));

但是，这似乎并不在子类画廊工作。任何想法，为什么？

But that doesn't seems to work on the sub-class Gallery. Any idea why?

推荐答案

如果你们有这个问题，尝试摆脱画廊间距值的 - 这解决了我

If you guys have this problem, try get rid of the gallery spacing value -- that solved it for me.
