我正在使用Androis Studio 3.0 Canary 4.在我的项目中,我有Linkedin-sdk,它的工作原理.我可以用它.唯一的问题是,当我搜索构建Gradle时,我会收到此消息.

因为我不能构建它我不能使用设计编辑器和预览.

这是我的build.gradle项目:

buildscript {
  repositories {
    jcenter()
    maven { url 'https://maven.google.com' }
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0-alpha4'
    classpath 'com.google.gms:google-services:3.0.0'
  }
}

allprojects {
   repositories {
       jcenter()
       maven {
           url 'https://maven.google.com'
       }
   }
}

task clean(type: Delete) {
     delete rootProject.buildDir
}

Build.Gradle模块:App

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.0"
    defaultConfig {
           applicationId "com.cving_team.cving"
           minSdkVersion 19
           targetSdkVersion 26
           versionCode 1
           versionName "1.0"
           testInstrumentationRunner 
           "android.support.test.runner.AndroidJUnitRunner"
}
signingConfigs {...}
buildTypes {
    sdkTest {
        signingConfig signingConfigs.sdkTest
        debuggable true …

我的目的是让一个看不见的LinearLayout在点击特定按钮时显示为动画.为此,我将默认高度设置为WRAP_CONTENT,获取应用程序启动时的高度,将高度设置为0,并在单击按钮时启动动画.这是代码:

linearLayout.post(new Runnable() {
    @Override
    public void run(){
        height = linearLayout.getMeasuredHeight();
        linearLayout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, 0));
    }
});


findViewById(R.id.btnOperator).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Animation ani = new ShowAnim(linearLayout, height/* target layout height */);
        ani.setDuration(1000/* animation time */);
        linearLayout.startAnimation(ani);

    }
});

这项工作还不错,但我想做的不同.我希望默认高度为0,然后计算WRAP_CONTENT高度,并将其传递给:

Animation ani = new ShowAnim(linearLayout, height/* target layout height */);

我怎么能这样做？我搜索但发现了什么.

我使用Retrofit和OkHttp3来发出请求.我知道在Android 4.4 TLS 1.1和TLS 1.2中没有启用defult.所以我想尝试启用它们.但到目前为止,我没有成功.我读到这可能是android工作室模拟器的一个问题,但是我无法在带有andoroid 4.4 rigthnow的真实设备上进行测试

这是我到目前为止所做的:

private <S> S createService(Class<S> serviceClass) {
    Retrofit retrofit = builder.client(getNewHttpClient()).build();
    return retrofit.create(serviceClass);
}

private OkHttpClient getNewHttpClient() {
    OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder()
            .connectTimeout(10, TimeUnit.SECONDS)
            .writeTimeout(10, TimeUnit.SECONDS)
            .readTimeout(0, TimeUnit.MINUTES); // Disable timeouts for read

    return enableTls12OnPreLollipop(clientBuilder).build();
}


public static OkHttpClient.Builder enableTls12OnPreLollipop(OkHttpClient.Builder client) {
    if (Build.VERSION.SDK_INT == Build.VERSION_CODES.KITKAT) {
        try {
            client.sslSocketFactory(new TLSSocketFactory());

            ConnectionSpec cs = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
                    .tlsVersions(TlsVersion.TLS_1_2)
                    .build();

            List<ConnectionSpec> specs = new ArrayList<>();
            specs.add(cs);
            specs.add(ConnectionSpec.COMPATIBLE_TLS);
            specs.add(ConnectionSpec.CLEARTEXT);

            client.connectionSpecs(specs);
        } catch (Exception exc) { …
