TaskStackBuilder过渡动画 [英] TaskStackBuilder transition animation
问题描述
我正在使用Android L过渡,其目的是传递 ActivityOptions
捆绑包。
如何使用 TaskStackBuilder
以相同的意图重现动画?
I'm using Android L transitions passing an ActivityOptions
bundle in intent.
How can I reproduce the animation on the same intent with TaskStackBuilder
?
这是我目前的工作具有单个 Intent
的方法:
This is my current working method with a single Intent
:
startActivity(myIntent, ActivityOptions.makeSceneTransitionAnimation(this).toBundle());
这是我尝试使用 TaskStackBuilder
:
TaskStackBuilder builder = TaskStackBuilder.create(this);
builder.addNextIntentWithParentStack(myIntent);
builder.startActivities(ActivityOptions.makeSceneTransitionAnimation(this).toBundle());
但是该动画会产生一种奇怪的效果,与单意图版本不同。
But the animation creates a strange effect, not the same one of the "single-intent" version.
我也尝试过:
builder.addNextIntent(myIntent);
而不是:
builder.addNextIntentWithParentStack(myIntent);
推荐答案
在 TaskStackBuilder内部进行挖掘之后/ code>的实现,问题在于它强制将
Intent.FLAG_ACTIVITY_CLEAR_TASK
添加到堆栈的第一个intent中,这产生了奇怪的效果,因此请使用以下开始堆栈:
After digging inside TaskStackBuilder
's implementation, the problem is that it forces adding Intent.FLAG_ACTIVITY_CLEAR_TASK
to the 1st intent in the stack, which makes that strange effect, so use the following to start the stack:
Intent[] intents = TaskStackBuilder.create(this)
.addNextIntentWithParentStack(myIntent)
.getIntents();
if (intents.length > 0) {
intents[0].setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);// Or any other flags you want, but not the `.._CLEAR_..` one
}
// `this` inside current activity, or you can use App's context
this.startActivities(intents, ActivityOptions.makeSceneTransitionAnimation(this).toBundle());
这里的想法是仍然使用 TaskStackBuilder
创建您的意图栈,然后删除 TaskStackBuilder
添加到第一个意图的奇怪的 Intent.FLAG_ACTIVITY_CLEAR_TASK
然后使用所需的任何上下文手动启动活动。
The idea here is to still use the TaskStackBuilder
for creating your intents' stack, then remove the weird Intent.FLAG_ACTIVITY_CLEAR_TASK
that the TaskStackBuilder
adds to the 1st intent, then start the activities manually using any Context you want.
