Custom Back Button Animation
提问by dfetter88
The default animation when the Backbutton is pressed is a slide from left to right. I'd like to replace that with a custom animation. I'm currently thinking that some combination of onBackPressed()and overridePendingTransitionwill do the trick, but I haven't been able to get it working.
Back按下按钮时的默认动画是从左向右滑动。我想用自定义动画替换它。我目前认为的某种组合onBackPressed()，并overridePendingTransition会做的伎俩，但我一直没能得到它的工作。

I think you shouldn't use finish() because the data stored by the Views will be erased
我认为你不应该使用 finish() 因为视图存储的数据将被删除
@Override
public void onBackPressed() {
super.onBackPressed();
overridePendingTransition(R.anim.zoom_enter, R.anim.zoom_exit);
}

Figured it out. I wasn't finshing the current activity. The following code does the trick.
弄清楚了。我没有完成当前的活动。以下代码可以解决问题。
@Override
public void onBackPressed() {
[This Activity].this.finish();
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
}

I wouldn't use onBackPressed()since it's a hack when we use Fragments and we need to handle the stack, for instance. I proposed a more elegant solution here:
我不会使用，onBackPressed()因为当我们使用 Fragments 并且我们需要处理堆栈时，这是一个黑客。我在这里提出了一个更优雅的解决方案：
