The advanced road of Android rookie-OkHttp

1. Action http request

2. Usage:

(1). Since it is developed by a third-party company, it is necessary to add the dependency of the OkHttp library to build.gradle

dependencies {
    implementation 'com.squareup.okhttp3:okhttp:3.4.1'}

In older versions, implementation was compile

(2).

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Button sendRequest = (Button)findViewById(R.id.send_request);
responseText = (TextView)findViewById(R.id.response_text);
sendRequest.setOnClickListener(new View.OnClickListener(){
        @Override
public void onClick(View v) {
            if(v.getId() == R.id.send_request){sendRequestWithOKHttp();
                
                
            }
        }
    });
}

private void sendRequestWithOKHttp(){
    new Thread(new Runnable() {
        @Override
public void run() {
            try {        
                OkHttpClient client = new OkHttpClient();
                Request request = new Request.Builder()
                        .url("http://192.168.135.2:10000/student.xml")
                        .build();
                Response response = client.newCall(request).execute();
                String responseData = response.body().string();
showResponse(responseData);
}catch (IOException e){                
               
            
                e.printStackTrace () ;
            }

        }
    }).start();
}
