Question

我已经改变了一些活动的主题，但是当我想要运行AVD时，请转到强制停止。这是我的活动清单：

<activity
        android:name="com.example.gpsportalsms.LoginActivity"
        android:theme="@android:style/Theme.Translucent."
        android:label="@string/title_activity_login" >
        <intent-filter>

这是我的xml活动：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.gpsportalsms.LoginActivity"
android:background="@drawable/background3"
tools:ignore="MergeRootFrame" >


</FrameLayout>

我在下面添加了LogCat：

有什么问题？

Answer 1

删除“。”在Theme.Translucent。

使用此

 <activity
    android:name="com.example.gpsportalsms.LoginActivity"
    android:theme="@android:style/Theme.Translucent"
    android:label="@string/title_activity_login" >

Answer 2

快速搜索让我想到了这个问题：How to make an Android Translucent theme a little darker?

然而，上述问题与您的问题并无太大关系，但提供了一些参考。哈文试过了。

正如它所说的代码必须像

<activity
        android:name="com.example.gpsportalsms.LoginActivity"
        android:theme="@android:style/Theme.Translucent"
        android:label="@string/title_activity_login" >

请注意＆＃39; 。＆＃39;不应该在那里。
