我如何将活动中的 okhttp3 类分离到另一个类

Question

我在活动中创建了 okhttp3 方法并且效果很好，但是我想从另一个活动中调用这个 okhttp3 方法，所以我相信我需要通过创建单独的类来分离这个 okhttp3，所以我需要帮助如何创建单独的 okhttp3 类

这是我在活动中创建的方法

public void getJsonData(final int method, final String email, final String password, final String page, final String token){
        OkHttpClient client = new OkHttpClient();
        Request request;
        RequestBody formBody;
        HttpUrl gurl;
        //mToken = token;
        if(networkIsAvailable()){
            if(method == POST){
                mProgressBar.setVisibility(View.VISIBLE);
                String url = "http://35.240.138.251/api/auth/login";
                formBody = new FormBody.Builder()
                        .add("email", email)
                        .add("password", password)
                        .build();
                request = new Request.Builder()
                        .url(url)
                        .post(formBody)
                        .build();
            } else {
                 gurl = new HttpUrl.Builder()

                        .addPathSegment("api")
                        .addPathSegment(page)

所以 json 数据被传递给 JsonManager 类并由该类保存到数据库。 我想从另一个活动中调用此方法，因此我不必在另一个活动中重复相同的方法..请分享您的想法..

Answer 1

1. 您可以创建一个 BaseActivity，然后所有活动都扩展它，
2. 将您的方法移至 BaseActivity，
3. 您可以在任何扩展 BaseActivity 的 Activity 中调用它。

follow 是你的 BaseActivity

public class BaseActivity extends Activity{ 
    //here is your method body
    public String methodA(Runnable run){
        //handle your result in run
        runOnUiThread(run);
        return "hello-world";
    }
}

follow 是你的 ActivityA

public class ActivityA extends BaseActivity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        //invoke methodA
        String myData = methodA(new Runnable(){
        @Override
        public void run() {
            //handle json data
        }
    });
    }
}
