下面，我在主题中添加了 EditText 样式.我也增加了宽度和高度.所以我从 edittext 视图中删除了 android:layout_width 和 android:layout_height .但这是在说错误.如果我添加宽度和高度，它工作正常.有什么区别.主题不适用于我的edittext视图吗?

Below i have added EditText style in theme. I have added width and height also. So i removed android:layout_width and android:layout_height from my edittext view. But it is saying error. If i add width and height it is working fine. What is the difference. Is theme is not applying to my edittext view?

<style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
        <item name="android:editTextStyle">@style/custom_EditTextStyle</item>
</style>
<style name="custom_EditTextStyle" parent="@android:style/Widget.EditText">
         <item name="android:background">@drawable/edittextbox</item>
         <item name="android:singleLine">true</item>
         <item name="android:layout_width">fill_parent</item>
         <item name="android:layout_height">48dp</item>
    </style>

我的editText视图

My editText view

 <EditText android:hint="Username" />

推荐答案

您的 styles.xml 必须包含

<在顶部资源xmlns:android ="http://schemas.android.com/apk/res/android"> .

如果此文件是自动生成的，或者您是自己创建的，则有时会忘记此属性.

If this file was auto-generated or you made this file yourself, this attribute is sometimes forgotten.
