消除 activity 启动时白屏、黑屏问题

默认情况下 activity 启动的时候先把屏幕刷成白色，再绘制界面，绘制界面或多或少有点延迟，这段时间中你看到的就是白屏，显然影响用户体验，怎么消除呢？

在 Activity theme 设置style 即可

[html] view
plaincopy

<style name="AppTheme" parent="android:Theme.Light.NoTitleBar">

<item name="android:windowIsTranslucent">true</item>

<item name="android:windowNoTitle">true</item>

<item name="android:windowActionBar">false</item>

<item name="android:windowBackground">@android:color/transparent</item>

<!-- All customizations that are NOT specific to a particular API-level can go here. -->

</style>

[html] view
plaincopy

<application

android:name="com.skymobi.moposns.MyApplication"

android:allowBackup="true"

android:icon="@drawable/ic_launcher"

android:label="@string/app_name"

android:theme="@style/AppTheme" >

<activity

android:name="com.skymobi.moposns.MainActivity"

android:label="@string/app_name"

android:screenOrientation="portrait" >

<intent-filter>

<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

</activity>
