问题描述

在我的Andr​​oid应用程序，我需要使用 Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK 来设置我的意图的标志。我可以删除我所有的previous 活动，并开始一个新的活动在这个way.This是我的code如下：

In my android app, I need to use Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK to set my intent flag. I can remove all my previous Activities and start a new Activity in this way.This is my code below:

Intent intent = new Intent(Gerenxinxi.this, MainPart.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
finish();
overridePendingTransition(0,0);

不过，我发现黑屏闪烁，当我使用code以上。如果我没有设置标志的意图与 Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK ，黑屏闪烁会gone.My的问题是：我能做些什么来避免黑屏时 Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK 设置？

However,I found a flicker of black screen when i use the code above. If I don't set intent flag with Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK , the flicker of black screen will be gone.My question is: what can I do to avoid the black screen when Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK is set ?

推荐答案

这是你看到的是所谓的preVIEW屏幕此初始屏幕。您可以通过在你的主题声明这个彻底禁用：

This initial screen that you see is called the "Preview" screen. You can disable this completely by declaring this in your theme:

android:windowDisablePreview

<style name="Theme.MyTheme" parent="android:style/Theme.Holo">
    <!-- This disables the black preview screen -->
    <item name="android:windowDisablePreview">true</item>
</style>
