当使用overridePendingTransition，修改UI的意见，在所谓的活动是很慢 [英] When using overridePendingTransition, modifying UI views in the called activity is very slow

问题描述

几天前，我曾与基于的结果更新一个操作栏菜单图标问题的AsyncTask ：<一href="http://stackoverflow.com/questions/29239804/updating-action-bar-menu-item-due-to-asynctask-result-without-delay">Updating操作栏菜单项，由于AsyncTask的结果毫不拖延

a few days ago, I had a problem with updating an Action Bar menu icon based on the result of an AsyncTask: Updating Action Bar Menu Item due to AsyncTask result without delay

现在我意识到，这个问题是不是在所有涉及到的的AsyncTask 或操作栏。出现该问题，以及如果我想换一个的TextView 或任何其它查看。

Now I realized that this problem is not at all related to an AsyncTask or an Action Bar. The problem occurs as well if I want to change a TextView or any other View.

在摸索一段时间后，我意识到，这个问题是由overridePendingTransition我在活动使用它调用第二个活动（在这里我想更改图标）：

After some time of trial and error I realized that the problem is caused by overridePendingTransition which I use in the Activity which calls the second Activity (where I want to change the icon):

首先活动（在onItemClick法）：

First Activity (in an onItemClick method):

@Override
   public void onItemClick(View view, int position) {
   ...
   Intent intent = new Intent(getActivity(), SecondActivity.class);
   ...
   startActivityForResult(intent, anyValue);
   getActivity().overridePendingTransition(R.anim.slide_in_right, R.anim.no_animation);
}

动画看起来就像是：

The animation looks like that:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="100%p" android:toXDelta="0"
            android:duration="@android:integer/config_shortAnimTime"/>
</set>

这是第二个活动的AsyncTask的（onPostExecute）怎么是这样的：

And this is how the AsyncTask (onPostExecute) of the second Activity looks like:

@Override
public void onPostExecute(String result) {
   super.onPostExecute(result);
   if (mMenu != null) {
      if (result.equals("no favorite")) {
      ...
      mMenu.findItem(R.id.action_favorite).setVisible(false);
      mMenu.findItem(R.id.action_no_favorite).setVisible(true);
   } else {
      ...
      mMenu.findItem(R.id.action_favorite).setVisible(true);
      mMenu.findItem(R.id.action_no_favorite).setVisible(false);
   }
}

正如所解释的，而不是两个菜单图标之间切换，则也可以使用一个TextView的以及基于结果中的文本 - 的问题仍然存在。

As explained, instead of switching between two menu icons, you could also use one TextView and setting the text based on the result - the problem remains.

你知道我可以改变动画，而无需在我的第二个活动这个奇怪的延迟？

Do you know how I can change the animation without having this weird delay in my second Activity?

推荐答案

检查 integer.xml 文件 使价值 config_shortAnimTime 根据您的需求较小。 它以毫秒为单位。 preFER使得1000（1秒）。的

Check your integer.xml file Make the value of config_shortAnimTime smaller according to your needs. Its in milliseconds. Prefer making it 1000 (1 sec).
