Android 通过开源框架AsyncHttpClient进行get和post请求

public void asyncHttpClientGet(View view) {
AsyncHttpClient client = new AsyncHttpClient();
client.get(
"http://10.0.2.2:8080/LoginServlet?username=张三&password=123",
new AsyncHttpResponseHandler() {
@Override
public void onSuccess(String response) {
Toast.makeText(MainActivity.this, response,
Toast.LENGTH_SHORT).show();
}
});
}

public void asyncHttpClientPost(View view) {
AsyncHttpClient client = new AsyncHttpClient();
RequestParams requestParams = new RequestParams();
requestParams.add("username", "张三");
requestParams.add("password", "123");
client.post("http://10.0.2.2:8080/LoginServlet", requestParams,
new AsyncHttpResponseHandler() {
@Override
public void onSuccess(String response) {
Toast.makeText(MainActivity.this, response,
Toast.LENGTH_SHORT).show();
}
});
}
