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

 

    <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>  

 

 

 

    <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>
