我正在使用Android L转换在意图中传递ActivityOptions包。
如何使用TaskStackBuilder以相同的意图重现动画？
这是我目前的工作方法，只有一个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());
但动画会产生奇怪的效果，而不是“单一意图”版本。
我也尝试过：
builder.addNextIntent(myIntent);
而不是：
builder.addNextIntentWithParentStack(myIntent);

尝试使用：
TaskStackBuilder.create (Context context)
返回一个新的TaskStackBuilder，用于启动由一系列活动组成的新任务堆栈。 参数 -
Context context：将启动新任务堆栈或生成PendingIntent的上下文。
返回TaskStackBuilder - 一个新的TaskStackBuilder。

的实现之后，问题在于它迫使将TaskStackBuilder添加到堆栈的第一个intent中，这产生了奇怪的效果，因此请使用以下内容启动堆栈：
Intent.FLAG_ACTIVITY_CLEAR_TASK这里的想法是仍然使用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());
创建意图栈，然后删除TaskStackBuilder添加到第一意图的奇怪的Intent.FLAG_ACTIVITY_CLEAR_TASK，然后手动开始活动使用您想要的任何上下文。
