使用handler和Message获取xutils发送POST请求从服务器端返回数据

public class MainActivity extends Activity{
private String responseInfo;
private Handler handler;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
handler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
responseInfo = (String) msg.obj;
Gson gson = new Gson();
Type type = new TypeToken<JsonBean>() {
}.getType();
JsonBean jsonBean = gson.fromJson(responseInfo, type);
System.out.println(jsonBean);
}
};
getFromServer();
}
