java - 如何控制Activity方法流直到非Activity类执行网络操作

Question

我在 Activity 中有一种方法，其中一些操作是从非 Activity 类执行的。我想知道非 Activity 类网络操作何时完成，以便我可以再次调用该方法。但是当我调用非 Activity 类时，方法会转到最后。

这是我的代码

public void somemethod(){
            .
            .
            .
            .               
if (condition) {

    new RegenerateToken().generate(DriverActivity.this); // calling non activity class which perform some network operation

    //here i want to know that non activity class has performed the network operation so i can call this method again

    }       
            .
            .
            .
log.d("method","ending");
}

非 Activity 类

public class RegenerateToken {
    public void generate(Context context) {
    
    ExecuteServerReq executeServerReq = new ExecuteServerReq(context, client, Utilz.URL + "/authenticate", params, true, true);
    executeServerReq.execute();
    executeServerReq.getResponse = new ExecuteServerReq.GetResponse() {
    
    @Override
    public void onResponse(String objects) {
      Utilz.printLog("RegenerateTokenresponse", objects);
    }
    };
    }
}

Answer 1

你需要实现一个接口(interface)来获取回调

public class RegenerateToken {

public interface Callback {
    public void onResponce(String data);
}

public void generate(Context context,final Callback callBack) {
    ExecuteServerReq executeServerReq = new ExecuteServerReq(context, client, Utilz.URL + "/authenticate", params, true, true);
    executeServerReq.execute();
    executeServerReq.getResponse = new ExecuteServerReq.GetResponse() {

    @Override
    public void onResponse(String objects) {
        Utilz.printLog("RegenerateTokenresponse", objects);
        callBack.onResponce(objects);
    }};
}
}

回调实现

if(condition) {
    new RegenerateToken().generate(DriverActivity.this, new Callback() {  
        @Override
        public void onResponse(String objects) { //your data do ur processing
        }
    });
}
