android - Android中的活动背景

Question

我有一个背景颜色为黑色的活动。

它有edittext，并且在软键盘消失后，有一会儿我看到键盘下方的白色区域；然后视图被调整大小。

这看起来像眨眼。

问题是，是否可以为整个应用程序设置某种默认背景颜色？（假设我的活动已经有背景属性）

windowSoftInputMode 也不是一个选项

If you want to specify the background to your whole application, you may edit the app theme or add custom theme to your application manifest. But this will be overridden when background is specified in the xml layout.

Add custom theme in style.xml

<style name="MyTheme" parent="android:Theme">            
        <item name="android:background">@android:color/black</item>
    </style>

Specify the theme in manifest as

<application           
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/MyTheme" >

Adding theme for each activity in manifest

<activity
            android:name=".Login"
            android:configChanges="orientation"
            android:theme="@style/MyTheme>
        </activity>

You can also modify the existing theme in style.xml which is already defined in manifest by changing the background as desired

<item name="android:background">@android:color/black</item>
