小编a_s*_*ber的帖子

在我的安卓应用中：

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.jakewharton.retrofit2.adapter.kotlin.coroutines.CoroutineCallAdapterFactory;

import java.util.concurrent.TimeUnit;

import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

private static Retrofit.Builder builder = new Retrofit.Builder()
            .baseUrl(BuildConfig.API_BASE_URL)
            .addConverterFactory(GsonConverterFactory.create(gson))
            .addCallAdapterFactory(CoroutineCallAdapterFactory.Companion.create())
            .client(httpClient.build());


public class Trader implements Serializable {
    private String id;
    private long last_iteration_time;
   private double last_bnc_btx_diff_entrance_percent;
}

改造接口方法：

import kotlinx.coroutines.Deferred
import com.myproject.model.Trader
import retrofit2.Response
import retrofit2.http.GET
import retrofit2.http.Path
import retrofit2.http.Query


@GET("traders/json")
suspend fun getTraidersList(): Deferred<Response<List<Trader>>>

并使用它：

suspend fun getTraidersList(): TransportResponse = withContext(Dispatchers.IO) {
            val traderMonitorRestClient = RestClientFactory.createRestClient(TraderMonitorRestClient::class.java)
            val operrationDeferred: Deferred<Response<List<Trader>>> = traderMonitorRestClient.getTraidersList()
            executeAwaitOperation(operrationDeferred) …

在我的 agent_details_activity.xml 中：

 <ImageView
            android:id="@+id/imageViewPhoto"
            android:layout_width="0dp"
            android:layout_height="400dp"
            app:agentImageUrl="@{item.url}"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/toolBarContainer" />

在活动中：

class AgentDetailsActivity : AppCompatActivity() {
    private lateinit var binding: AgentDetailsActivityBinding

    companion object {
        val AGENT_DETAILS = AgentDetailsActivity::class.java.name + "_AGENT_DETAILS"
    }

    private val TAG = AgentDetailsActivity::class.java.name

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = AgentDetailsActivityBinding.inflate(layoutInflater)
        setContentView(binding.root)
        binding.setHandler(this);
    }

  @BindingAdapter("agentImageUrl")
    fun loadImage(view: ImageView, imageUrl: String) {
        Glide.with(view.context)
            .load(imageUrl)
            .apply(RequestOptions().error(R.drawable.no_image))
            .into(view)
    }

但在运行时我得到错误：

Android Studio 2.3.2.我想导出实时模板 - > AndroidLog到文件.

我怎么能这样做？谢谢.

我在我的项目中使用 Gradle 6.1 版。

该项目的build.gradle如下：

plugins {
    id 'application'
}

application {
    mainClass = 'com.mytestproject.Main'
}

java {
    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8
}

group 'com.mytestproject'
version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

但是当我运行这个命令时./gradlew assemble，它给了我下面给出的错误：

./gradlew assemble

FAILURE: Build failed with an exception.

Linux 薄荷 20.2

PostgreSQL 9.6。

脚步：

sudo systemctl enable postgresql.service

结果：

Synchronizing state of postgresql.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable postgresql

然后像这样重新启动服务：

sudo service postgresql restart

当检查状态时，如下所示：

service postgresql status

我明白了：

postgresql.service - PostgreSQL RDBMS
     Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor preset: enabled)
     Active: active (exited) since Wed 2021-08-04 17:33:34 EEST; 47s ago
    Process: 29261 ExecStart=/bin/true (code=exited, status=0/SUCCESS)
   Main PID: 29261 (code=exited, status=0/SUCCESS)

为什么服务已退出？

爪哇8，

我想在我的 java 项目中使用 JUnit 4。

在我的 build.gradle 中

dependencies {
    implementation 'org.apache.commons:commons-lang3'
    implementation 'org.apache.logging.log4j:log4j-api'
    implementation 'org.apache.logging.log4j:log4j-core'

    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core-jvm:1.5.2'

   testImplementation('org.assertj:assertj-core:3.21.0')
   testImplementation('org.mockito:mockito-core:4.0.0')

   testImplementation('junit:junit:4.13.2')

}

这是我的单元测试：

import org.junit.BeforeClass;
import org.junit.Test;

import java.util.*;

import static org.assertj.core.api.Assertions.assertThat;

public class VsatVlansNSTest {


    @BeforeClass
    public static void setupAll() {
     //
    }

    @Test
    public void find_NS_2_4_higher_matcher() {
     // some test here
    }
}

但我收到错误：

    public static void main(String[] args) {
        System.out.println(new App().getGreeting());

我的Android模拟器位于文件夹中:

d:\程序\的Android\avd.android\AVD\Nexus_4_4.avd \

假设我在文件夹D:\ temp中.

如何从文件夹D:\ temp我可以启动我的模拟器(从PC的命令行)？

在我的 Kotlin, Retrofit 2 项目中：

class TransportService {

    // static analog
    companion object {
        @JvmStatic
        fun checkoutSessions(bodyMap: Map<String, Any>, callback: Callback<Void>) {
            val stripeMonitorRestClient = RestClientFactory.createRestClient(StripeRestClient::class.java!!)
            val headerMap = mutableMapOf<String, String>()
            headerMap["Accept"] = "application/json"
            headerMap["Content-Type"] = "application/x-www-form-urlencoded"
            headerMap["Stripe-Version"] = "2019-03-14; checkout_sessions_beta=v1"
            headerMap["Authorization"] = "Bearer sk_test_4eC39HqLyjWDarjtT1zdp7dc"
            val adMessagesList = stripeMonitorRestClient.checkoutSessions(headerMap, bodyMap) // error here 
            // asynchronously
            adMessagesList.enqueue(callback)
        }
    }

}

和休息客户端api：

import retrofit2.Call
import retrofit2.http.FieldMap
import retrofit2.http.HeaderMap
import retrofit2.http.POST
import retrofit2.http.FormUrlEncoded


interface StripeRestClient {

    @FormUrlEncoded
    @POST("checkout/sessions")
    fun checkoutSessions(@HeaderMap headers: Map<String, String>, …

在我的 Android 应用程序中，我使用 Retrofit 2：

public enum OperationType {
    @SerializedName("payment")
    PAYMENT,
    @SerializedName("payout")
    PAYOUT,
    @SerializedName("transfer")
    TRANSFER
}




fun getOperationsList(typeList: List<OperationType>, callback: Callback<List<Operation>>) {
        val call = myRestClient.getOperationsList(typeList)
        executeRequest(call, callback)
}


@GET("/operations")
fun getOperationsList(@Query("type") typeList: List<OperationType>): Call<List<Operation>>

但我在这一行收到运行时错误：

val call = myRestClient.getOperationsList(typeList)

错误：
