问题描述
[已修复] 添加依赖项后,您需要同步项目.这是AVD Manager图标左侧的图标
大家好,
我正在尝试在 android studio 中使用 appcompat-v7.我添加了这些行:
I'm trying to use the appcompat-v7 with android studio.I add those lines:
dependencies {
compile 'com.android.support:appcompat-v7:18.0.+'
}
在 build.gradle 中,但是当我尝试导入 lib 时:
In the build.gradle but when I try to import the lib:
import android.support.v7.app.ActionBar;
它说我无法解析 v7 .. 当我检查文件夹 external lib 时,只有 support-v4.
It says me that cannot resolve v7 .. And when I check the folder external lib there is only support-v4.
我错过了什么吗?
Ps:它在另一个项目中工作,我可以在外部库中看到该库,但它不想再这样做了..
Ps: It worked in an other project and I could see the lib in external lib but it don't want do it again ..
推荐答案
你应该有两个依赖:
dependencies {
compile 'com.android.support:support-v4:18.0.+'
compile 'com.android.support:appcompat-v7:18.0.+'
}
确认您已在 SDK 管理器中下载了最新的 Android 支持库和支持库.
Verify that you have downloaded the latest Android Support Library and Support Repository within your SDK manager.
