我想在我的“ MainActivity”中实现“ NanoHttpd”服务器调用。在我的MainActivity中,我接收两个文本输入值,并调用另一个活动“ ValidCodeReceived”并传递这些值。如何在MainActivity中调用NanoHttpd并获取这些值?请告知

//'NanoHttpd'服务器代码:

public class MyServer extends NanoHTTPD {
    private final static int PORT = 8080;

    public MyServer() throws IOException {
        super(PORT);
        start();        
    }

    @Override
    public Response serve(IHTTPSession session) {   

        return new NanoHTTPD.Respon( );
    }
}

@Override
public void onResume() {
    super.onResume();
    try {
        server = new MyServer();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

@Override
public void onPause() {
    super.onPause();
    if(server != null) {
        server.stop();
    }
}

//以下现有的“ MainActivity”代码:

public class MainActivity extends AppCompatActivity {
    private EditText inputName, inputCode;
    public static  String strName = null;
    public static  String strCode = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);        
        inputName = (EditText) findViewById(R.id.editName);
        inputName.setTextColor(Color.parseColor("#63d0f2"));
        inputCode = (EditText) findViewById(R.id.editCode);
        Button button = findViewById(R.id.displayMap);  


        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                strName = inputName.getText().toString();
                strCode = inputCode.getText().toString();
                String myCode = inputCode.getText().toString();

                if(inputName.getText().length()<3 || inputName.getText() ==null ){                    
                    Toast.makeText(MainActivity.this, "Please enter valid name !",Toast.LENGTH_LONG).show();
                }else if (inputCode.getText().length()<4){

                    Toast.makeText(MainActivity.this, "Please enter a valid code !",Toast.LENGTH_LONG).show();
                }else if(myCode.matches("")){
                    Toast.makeText(MainActivity.this, "Code cannot be blank !",Toast.LENGTH_LONG).show();

                }else if(!myCode.matches(".*[A-Za-z].*") && !myCode.matches(".*[0-9].*") && !myCode.matches("[A-Za-z0-9]*")){
                    Toast.makeText(MainActivity.this, "Code field should have alpha numeric values",Toast.LENGTH_LONG).show();
                }
                else {
                    Intent intent = new Intent(MainActivity.this, ValidCodeReceived.class);                    
                    intent.putExtra("mainname", strName);
                    intent.putExtra("maincode", strCode);
                    startActivity(intent);
                }


            }
        });


    }

    @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);
    }
}

// ValidCodeReceived

public class ValidCodeReceived extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if( getIntent().getExtras() != null)
        {
            Intent intent = getIntent();
            String myData1 = intent.getStringExtra("mainname");
            String myData2 = intent.getStringExtra("maincode");
            TextView textView = new TextView(this);
            textView.setTextSize(20);
            textView.setText("Hello team, send by:"+ myData1 + " "+ myData2);
            setContentView(textView);
        }


    }

}
