拦截器模版附带MVP防止内存泄漏

post请求路径不用加后面的参数,放入Map中就行,公共参数在拦截器中

拦截器:

public class MyInterCeptor implements Interceptor {    @Override    public Response intercept(Chain chain) throws IOException {        Request request = chain.request();        HttpUrl build = request.url().newBuilder().addQueryParameter("source", "android").build();        Request build1 = request.newBuilder().url(build).build();        return chain.proceed(build1);    }}

OKHttpUtils:

public class OKHttpUtils {    Handler handler = new Handler();    private static volatile OKHttpUtils okhttputils;    public static OKHttpUtils getInstence(){        if(null==okhttputils){            synchronized (OKHttpUtils.class){                if(okhttputils==null){                    okhttputils = new OKHttpUtils();                }            }        }        return okhttputils;    }    public void post(String url, Map<String,String> map,final MView mview,final Class clas){        OkHttpClient client = new OkHttpClient.Builder()                .addInterceptor(new MyIntercapter())                .build();        FormBody.Builder builder = new FormBody.Builder();        if(map!=null&&!map.isEmpty()){            for(Map.Entry<String,String> entry:map.entrySet()){                builder.add(entry.getKey(),entry.getValue());            }        }        final Request request = new Request.Builder()                .url(url)                .post(builder.build())                .build();        Call call = client.newCall(request);        call.enqueue(new Callback() {            @Override            public void onFailure(Call call, final IOException e) {                handler.post(new Runnable() {                    @Override                    public void run() {                        mview.onShibai(e);                    }                });            }            @Override            public void onResponse(Call call, Response response) throws IOException {                String string = response.body().string();                Gson gson = new Gson();                final Object o = gson.fromJson(string, clas);                handler.post(new Runnable() {                    @Override                    public void run() {                        mview.onChenggong(o);                    }                });            }        });    }}

防止内存泄漏:

V层//判断new的P层为不为空,为空调用P层的销毁方法

protected void onDestroy() {
        super.onDestroy();

        if (presenter != null) {
            presenter.detachView();
        }
    }

P层:

判断V层的接口为不为空,不为空变为空

public void detachView() {
        if (null != iv) {
            iv = null;
        }
    }
