First effect:

Instructions:

1, use an Android phone or emulator
2, the server supports php
3, simple verification login operation
4, the network request uses the RxEasyHttp open source library, which is an encapsulation of okhttp3, retrofit, it is also possible to use okhttp3 directly
5, used for test login The url is always valid
6. If you need a server, you can use it with me. You can just send a few soft coins. There is no traffic limit or space limit.

Server-side php file

Android-side XML layout file

Android-side java code implementation

public class MainActivity extends AppCompatActivity {

    String loginUrl = "http://soyoyo.esy.es/login.php";

    EditText etName;
    EditText etPwd;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        etName  = findViewById(R.id.etName);
        etPwd = findViewById(R.id.etPwd);

    }

    // 点击button后执行
    public void doLogin(View view){
        login(etName.getText().toString(),etPwd.getText().toString());
    }

    private void login(String name,String pwd){
        EasyHttp.post(loginUrl)
                .baseUrl(url)
                .params("loginName",name)
                .params("loginPwd", pwd)
                .execute(new CallBack() {

                    @Override
                    public void onStart() {
                        System.out.println("------onStart------");
                    }

                    @Override
                    public void onCompleted() {
                        System.out.println("------onCompleted------");
                    }

                    @Override
                    public void onError(ApiException e) {
                        e.printStackTrace();
                    }

                    @Override
                    public void onSuccess(String s) {
                        System.out.println("------onSuccess------" + s);
                        Toast.makeText(MainActivity.this,s,Toast.LENGTH_SHORT).show();
                    }
