我在SDK中安装了Google Play Services,然后在其'Layout'按钮代码中添加了Google
<com.google.android.gms.common.SignInButton
android:id="@+id/sign_in_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
有一个错误:
Rendering Problems The following classes could not be found:
- com.google.android.gms.common.SignInButton (Fix Build Path, Create Class)
Tip: Try to build the project.
我在我的构建文件中添加一行:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
--> compile 'com.google.android.gms:play-services-ads:8.3.0'
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile files('libs/bolts-android-1.2.1.jar')
compile files('libs/Parse-1.10.3.jar')
}
但是还是不行。我怎样才能让按钮出现?
最佳答案
您添加了错误的依赖项。您应该为登录按钮添加这个。
compile 'com.google.android.gms:play-services-auth:8.4.0'
