我按照教程创建了一个登录/注册，并将其与gradle连接起来。它不允许我为我的代码添加图像，所以如果有效的话我会粘贴它...
我添加了XML
我为 buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
classpath 'com.google.gms:google-services:3.1.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
maven { url 'https://maven.google.com' }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.example.saiyarram.perfectit"
minSdkVersion 16
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
packagingOptions {
exclude 'META-INF/NOTICE' // will not include NOTICE file
exclude 'META-INF/LICENSE' // will not include LICENSE file
// as noted by @Vishnuvathsan you may also need to include
// variations on the file name. It depends on your dependencies.
// Some other common variations on notice and license file names
exclude 'META-INF/notice'
exclude 'META-INF/notice.txt'
exclude 'META-INF/license'
exclude 'META-INF/license.txt'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])

添加了互联网选项
当我运行应用程序时运行正常，当我输入用户名和密码并单击注册按钮时，它会显示
