一.使用场景,及业务需求

在Android项目开发中,为了让你的App能够连接后台服务器获取后台数据,在数据加载过程中弹出相应的"正在加载...."提示语,在网络或者服务器异常时请求失败弹出"加载失败,请重新请求",

二.写这篇博客原因

com.zhy:okhttputils:2.6.2'这个可以依赖的项目是Android大神鸿洋封装好的一个网络请求框架,我们可以把它集成到我们的项目中,为了更方便的使用它,我们需要在这个框架的基础上自定义MyOkhttpUtils再次封装,使我们的代码更优雅.

三.集成鸿洋的这个框架

1.在Android工程目录下的build.gradle文件中依赖

//okhttp3
implementation 'com.squareup.okhttp3:mockwebserver:3.11.0'
implementation 'com.squareup.okio:okio:2.0.0'
//鸿洋okhttputils
implementation 'com.zhy:okhttputils:2.6.2'

2.自定义MyApplication配置OkhttpClient

public class MyApplication extends Application
{   
    @Override
    public void onCreate()
    {
        super.onCreate();

        OkHttpClient okHttpClient = new OkHttpClient.Builder()
                  .addInterceptor(new LoggerInterceptor("TAG"))
                  .connectTimeout(10000L, TimeUnit.MILLISECONDS)
                  .readTimeout(10000L, TimeUnit.MILLISECONDS)
                  //其他配置
                 .build();

        OkHttpUtils.initClient(okHttpClient);
    }

}

 private void okhttpint(){
        // 对Coolies进行持久化操作
        final ClearableCookieJar cookieJar1 = new PersistentCookieJar(new SetCookieCache(), new SharedPrefsCookiePersistor(getApplicationContext()));
        // 对https支持，参数分别为：证书的inputstream 本地证书的inputstream 本地证书的密码
        // 当前配置可以访问任何https网站
        HttpsUtils.SSLParams sslParams = HttpsUtils.getSslSocketFactory(null, null, null);
        OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .connectTimeout(10000L, TimeUnit.MILLISECONDS) // 连接超时时间
                .readTimeout(10000L, TimeUnit.MILLISECONDS) // 读取超时时间
                .addInterceptor(new LoggerInterceptor("TAG"))
                .cookieJar(cookieJar1)
                .sslSocketFactory(sslParams.sSLSocketFactory, sslParams.trustManager)
//                .sslSocketFactory(createSSLSocketFactory())
//                .hostnameVerifier(new TrustAllHostnameVerifier())
                .build();
        OkHttpUtils.initClient(okHttpClient);
    }

注意记得在清单文件中配置Application和网络权限

3.在工具类包下创建MyOkhttpUtils

public class MyOkhttpUtils {
    public static final String TYPE_TXT = "txt";
    public static final String TYPE_XLS = "xls";
    public static final String TYPE_DOC = "doc";
    public String sError = "网络连接失败";

    public static void getRequest(String url, final OnRequestNetWorkListener mListener) {
        OkHttpUtils
                .get()
                .url(url)
                .build()
                .execute(new StringCallback() {
                    @Override
                    public void onError(Call call, Exception e, int id) {
                        mListener.notOk(e.getMessage());
                        DialogUtils.getInstance().dismiss();
                    }

                    @Override
                    public void onResponse(String response, int id) {
                        mListener.ok(response);
                        DialogUtils.getInstance().dismiss();
                    }
                });
    }


    public static void postRequest(String url, HashMap<String, String> params, final OnRequestNetWorkListener listener) {

        PostFormBuilder builder = OkHttpUtils.post().url(url);

        Iterator<Map.Entry<String, String>> iterator = params.entrySet().iterator();
        while (iterator.hasNext()) {
            Map.Entry entry = iterator.next();
            String key = (String) entry.getKey();
            String value = (String) entry.getValue();
            builder.addParams(key, value);
        }

        builder.build().execute(new StringCallback() {
            @Override
            public void onError(Call call, Exception e, int id) {
                listener.notOk(e.getMessage());
                DialogUtils.getInstance().dismiss();
            }

            @Override
            public void onResponse(String response, int id) {
                listener.ok(response);
                DialogUtils.getInstance().dismiss();
            }
        });
    }

    /*

    public static void postRequestFile(String url, ArrayList<File> arrayListFile, String fileParameter, HashMap<String, String> params, final OnRequestNetWorkListener listener) {

</LinearLayout>

dialog_backgroud.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape>
            <corners android:radius="5dp" />
            <solid android:color="@android:color/black" />
        </shape>
    </item>
</selector>

5.ToastUtils

public class ToastUtils {
	public static Toast toast(Context context, String text) {
		
		Toast tos=Toast.makeText(context, text, Toast.LENGTH_SHORT);
		tos.show();
		return tos;
	}
	public void cancelToast(Toast toast) {    
		if (toast != null) {    
			toast.cancel();    
		}    
	}    
}

6.获取屏幕尺寸ScreenSize

public class ScreenSize {

	/**
	 * 手机屏幕的宽
	 * 
	 * @return
	 */
	public static int screenWidth(Context context) {
		Activity activity = (Activity) context;
		DisplayMetrics dm = new DisplayMetrics();
		activity.getWindowManager().getDefaultDisplay().getMetrics(dm);
		return dm.widthPixels;
	}

	/**
	 * 手机屏幕的高
	 * 
	 * @return
	 */
	public static int screenHeight(Context context) {
		Activity activity = (Activity) context;
		DisplayMetrics dm = new DisplayMetrics();
		activity.getWindowManager().getDefaultDisplay().getMetrics(dm);
		return dm.heightPixels;
	}

	public static int dp2px(int dpVal, Context context) {

		return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
				dpVal, context.getResources().getDisplayMetrics());

	}

	public static int sp2px(int spVal, Context context) {

		return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP,
				spVal, context.getResources().getDisplayMetrics());

	}
	public static int px2dip(Context context, float pxValue) {
		final float scale = context.getResources().getDisplayMetrics().density;
		return (int) (pxValue / scale + 0.5f);
	}
}

四.在项目使用

DialogUtils.getInstance().showDialog(getContext(), "加载中...");   
  MyOkhttpUtil.postRequest(Constant.APP_URL + "houseTypeList", map, new MyOkhttpUtil.OnRequestNetWorkListener() {
            @Override
            public void notOk(String err) {
                new Throwable("请求失败");
            }

            @Override
            public void ok(String response) {
                JSONObject jsonObject;
                try {
                    Log.e("Tag","丝路会展:"+response);
                    jsonObject= new JSONObject(response);
                    String status = jsonObject.getString("status");
                    Log.e("TAG",status);
                    if (status.equals("1")){

                        String data = jsonObject.getString("data");
                        Log.e("TAG",data);
                        JSONObject info = new JSONObject(data);
                        //户型列表
                        getHouseTypeList(info);
                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        });

    }
