类 TextHttpResponseHandler

java.lang.Object

com.loopj.android.http.AsyncHttpResponseHandler

com.loopj.android.http.TextHttpResponseHandler

所有已实现的接口:

ResponseHandlerInterface

直接已知子类:

BaseJsonHttpResponseHandler, JsonHttpResponseHandler

public abstract class TextHttpResponseHandler
extends AsyncHttpResponseHandler

Used to intercept and handle the responses from requests made using { AsyncHttpClient}. The { #onSuccess(int, Header[], String)} method is designed to be anonymously overridden with your own response handling code.

Additionally, you can override the { #onFailure(int, Header[], String, Throwable)}, { #onStart()}, and { #onFinish()} methods as required.

For example:

 AsyncHttpClient client = new AsyncHttpClient();
 client.get("http://www.google.com", new TextHttpResponseHandler() {
     @Override
     public void onStart() {
         // Initiated the request
     }

     @Override
     public void onSuccess(String responseBody) {
         // Successfully got a response
     }

     @Override
     public void onFailure(String responseBody, Throwable e) {
         // Response failed :(
     }

     @Override
     public void onFinish() {
         // Completed the request (either success or failure)
     }
 });
