在看《第一行代码》第二版按书上写的操作，导入百分比布局时出错。按网上的解决方法，尝试改了几个percent版本不好使。
在\Android\sdk\extras\android\m2repository\com\android\support\percent下打开**maven-metadata.xml**如下
<?xml version="1.0" encoding="UTF-8"?>
com.android.support
percent
25.3.1
22.2.0
23.0.0
23.0.1

AS里的**build.gradle**文件如下
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "26.0.1"
defaultConfig {
applicationId "com.example.jingzi.uilayouttest"
minSdkVersion 15
targetSdkVersion 24
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.android support:percent:24.0.0'
testCompile 'junit:junit:4.12'
}
更新时报错：**Error（27,13）Failed to reslove:com.android.support:percent:24.2.1**
请问应该如何解决？
