动作条或ActionBarSherlock - 顺利隐藏/显示动作条 [英] ActionBar or ActionBarSherlock - Smoothly Hide / Show the ActionBar

问题描述

我使用 ActionBarSherlock ，并试图隐藏/显示动作条的全屏图像，使用：

I'm using ActionBarSherlock, and attempting to hide / show the ActionBar for fullscreen images, using:

getSupportActionBar.hide();

和

getSupportActionBar.show();

但它是真的跳动和尴尬。有什么办法能让它更顺畅，或申请翻译/不透明度动画？

But it is really jumpy and awkward. Is there a way to make it smoother, or to apply a translation / opacity animation?

当ABS源的进一步检查，并通过观察其行为，它似乎已经定义动画的至少最小量。同样不能说是为标准的ActionBar

Upon further inspection of ABS source, and through observing its behavior, it seems to have at least a minimal amount of animation defined. The same cannot be said for the standard ActionBar.

只是为了完整性，这里是有关code，我呼吁从ImageView.click：

Just for completeness, here is the relevant code I'm call from an ImageView.click:

if( shouldRender )
{
  . . .

  getSupportActionBar().hide();

  getWindow().addFlags( WindowManager.LayoutParams.FLAG_FULLSCREEN );
}
else
{
  . . .

  getSupportActionBar().show();

  getWindow().clearFlags( WindowManager.LayoutParams.FLAG_FULLSCREEN );
}

值得一提的是，标志设置/结算也导致跳转，而是一个更引人注目的一个，所以我打算以后解决它，如果在​​所有。

It's worth noting that the flags setting / clearing also causes a jump, but a much less noticeable one, so I was going to tackle it later, if at all.

编辑： 这（由ABS的创建者）似乎指出，这是不可能的在本机动作条。我想我可以只修改定义了动画中的两个XML文件，但是这不会给我完全的平台渗透。

This (by the creator of ABS) seems to state that it's impossible on a native ActionBar. I suppose I could just edit the two XML files that define his animation, but that will not give me full platform penetration.

推荐答案

我用一个覆盖动作条

 requestWindowFeature(com.actionbarsherlock.view.Window.FEATURE_ACTION_BAR_OVERL‌​AY);

它不显示动画时，显示（） / 隐藏（）叫
