如何在改造中添加添加参数

Question

我是新来的android开发，并试图学习android改造。我正在尝试从用户接收cnic并将其传递给参数。我试着用不同的方法，但他们的工作不

MainActivity.java

public class MainActivity extends AppCompatActivity { 

EditText cnic; 
String url = "https://Homeweb.com"; 


TextView text_number_1, text_city_2, text_status_1 ; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    cnic=(EditText)findViewById(R.id.editText); 
    text_status_1 = (TextView) findViewById(R.id.text_status_1); 
    Button ButtonArray= (Button) findViewById(R.id.RetrofitArray); 
    //Button ButtonObject= (Button) findViewById(R.id.RetrofitObject); 

      ButtonArray.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
//    View VisibleArray = findViewById(R.id.RetrofitArray); 
        //    VisibleArray.setVisibility(View.GONE); 
//    View VisibleObject = findViewById(R.id.RetrofitObject); 
        //    VisibleObject.setVisibility(View.GONE); 
        getRetrofitArray(); 
       } 
      }); 



} 




void getRetrofitArray() { 

    //RetrofitArrayAPI.innerURL = "/Login.php?M_cnic=4956"; 
    Retrofit retrofit = new Retrofit.Builder() 
      .baseUrl(url) 
      .addConverterFactory(GsonConverterFactory.create()) 
      .build(); 

    RetrofitArrayAPI service = retrofit.create(RetrofitArrayAPI.class); 

     //Call<List<Student>> call = service.getDetails(); 
     //Call<List<Student>> call = service.getDetails(); 
    //service.login() 
    Call<Student> call = service.getDetails(); 


    call.enqueue(new Callback<Student>() { 
     @Override 
     public void onResponse(Response<Student> response, Retrofit retrofit) { 

      try { 
       String check; 
       text_status_1.setText("StudentId : " + response.body().getC_name()); 
         //text_status_1.setText("Status : " + StudentData.get(i). getC_name()); 
         //text_city_2.setText("city : " + StudentData.get(i).getCity()); 
          check=response.body().getStatus(); 
       if(check.equals("1")) 
       { 
        Toast.makeText(MainActivity.this, "Login In SuccessFully", Toast.LENGTH_SHORT).show(); 

        Intent i = new Intent(MainActivity.this,Detail.class); 

        startActivity(i); 


       } 

       else if (check.equals("0")) // login failure 

       { 

        Toast.makeText(MainActivity.this, "Invalid UserName/Pass ", Toast.LENGTH_SHORT).show(); 

       } 






      } catch (Exception e) { 
       Log.d("onResponse", "There is an error"); 
       e.printStackTrace(); 
      } 

     } 

     @Override 
     public void onFailure(Throwable t) { 
      Log.d("onFailure", t.toString()); 
     } 
    }); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 

    //noinspection SimplifiableIfStatement 
    if (id == R.id.action_settings) { 
     return true; 
    } 

    return super.onOptionsItemSelected(item); 
    } 
} 

我传递的CNIC现在直接 ReforfitArray.java

public interface RetrofitArrayAPI { 

/* 
* Retrofit get annotation with our URL 
* And our method that will return us details of student. 
*/ 


@GET("/Login.php?M_cnic=4956") 

Call<Student>getDetails(); 


    } 

Answer 1

基本上我是想将参数cnic添加到我的网址

我解决我的问题 在我的接口

Call<Student>getDetails(@Query("M_cnic") String M_cnic); 

Mainactivity

//RetrofitArrayAPI.innerURL = "/Login.php?M_cnic=4956"; 
    Retrofit retrofit = new Retrofit.Builder() 
      .baseUrl(url) 
      .addConverterFactory(GsonConverterFactory.create()) 
      .build(); 

    RetrofitArrayAPI service = retrofit.create(RetrofitArrayAPI.class); 
    String M_cnic = cnic.getText().toString(); 
    //Call<List<Student>> call = service.getDetails(); 
    //Call<List<Student>> call = service.getDetails(); 
    //service.login() 

    // M_cnic="4956"; 

    Call<Student> call = service.getDetails(M_cnic);
