我已经设置了一个与Android 5一起使用的素材主题，但是在尝试运行我的应用时遇到以下错误：
您需要使用Theme.AppCompat主题（或后代） 活性
我查看了我的代码并且似乎已经完成了所有内容并且真的找不到什么错误，所以任何帮助修复都会很棒！
我的build.gradle：
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.1"
defaultConfig {
applicationId "com.xxxxx.xxxxx"
minSdkVersion 14
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.+'
compile 'com.google.android.gms:play-services:6.5.87'
}
my v21 / style.xml
<?xml version="1.0" encoding="utf-8"?>

答案 0 :(得分：0)
只需将ActionBarActivity更改为Activity。
