android - Holo 主题在启动画面上不起作用...应用程序崩溃

Question

您好，我想为我的应用程序添加全息主题，但是当我检查我的初始图形布局时，它似乎不起作用并且我的应用程序崩溃了。我想为整个应用程序添加全息主题。此外，我想摆脱启动画面之前的屏幕。我不知道该怎么做

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sachinda.myfirstapp"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="19" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.Holo">
    <activity
        android:name="com.sachinda.myfirstapp.MainActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

这是日志

Answer 1

您的 Activity 可能会扩展 ActionbarActivity，在这种情况下您需要拥有 Theme.AppCompat 主题(或后代)。

你有什么

 android:theme="@android:style/Theme.Holo">

您的主题不是来自AppCompat。

有

 android:theme="@style/Theme.AppCompat

或从 AppCompat 派生的主题。

引用文档

使用支持库时，您必须改用 Theme.AppCompat 主题:

Theme.AppCompat for the "dark" theme.
Theme.AppCompat.Light for the "light" theme.
Theme.AppCompat.Light.DarkActionBar for the light theme with a dark action bar.
