推荐答案

首先，您必须实现一些rest api库.

First you have to implement some rest api libraries.

implementation('com.squareup.retrofit2:retrofit:2.1.0') {
    exclude module: 'okhttp'
}
implementation 'com.google.code.gson:gson:2.8.5'
implementation 'com.squareup.retrofit2:converter-gson:2.6.1'
implementation 'com.squareup.okhttp3:logging-interceptor:4.2.0'
implementation 'com.squareup.okhttp3:okhttp:4.2.0'
implementation 'androidx.recyclerview:recyclerview:1.1.0'

然后在创建该类的ApiClient ..之后，在其中编写以下代码

Then after create class ApiClient.. in this class write below code in it

public class ApiClient {
private static Retrofit retrofit = null;

public static Retrofit getClient() {

    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();


    retrofit = new Retrofit.Builder()
            .baseUrl("https://jsonplaceholder.typicode.com")
            .addConverterFactory(GsonConverterFactory.create())
            .client(client)
            .build();



    return retrofit;
}}

现在创建接口ApiInterface并在其中编写以下代码.

Now create Interface ApiInterface and write below code in it..

public interface ApiInterface {

@FormUrlEncoded
@POST("login/")
Call<Your Pojo Class> loginuser(@Field("method") String method, @Field("login_name") 
   String loginname,@Field("password") String password);}

在您的MainActivity中编写以下代码.

In your MainActivity Write belowe code..

APIInterface apiInterface;
apiInterface = APIClient.getClient().create(APIInterface.class);
Call<EarnAmount> call = apiInterface.loginuser("loginuser", loginid,password);



call.enqueue(new Callback<Your Pojo>() {
                                @Override
                                public void onResponse(Call<Your Pojo> call, Response<Your Pojo> response) {
                     //you will get some response
                     //you can handle response from here

                                }

                                @Override
                                public void onFailure(Call<Your Pojo> call, Throwable t) {
                        //check internet connection or something went wrong
                                }
                                });    }
