AndroidUtils

android 私人工具类集合

LazyFragment

懒加载fragment

Logger

文件日志类，任何高频读写情况下都能保证文件日志写入的稳定性，无须初始化随点随用

设置是否打印日志

Logger.setIsDebug(mActivity,false);

设置是否写入文件日志

Logger.setIsWriter(mActivity,true);

平常使用：

Logger.i(TAG,"this is a logger message");

Logger.e(TAG,"this is a error message",error);

PermissionHelper

权限申请统一处理类

PermissionHelper mHelper = new PermissionHelper(this);
mHelper.requestPermissions("请授予[录音]，[读写]权限，否则无法录音",
                new PermissionHelper.PermissionListener() {
                    @Override
                    public void doAfterGrand(String... permission) {
  						//成功回调
                    }
                    @Override
                    public void doAfterDenied(String... permission) {
                        //失败回调
                    }
                }, Manifest.permission.RECORD_AUDIO,Manifest.permission.WRITE_EXTERNAL_STORAGE);

权限回调方法必须处理，否则会导致不断拉取权限的问题

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (mHelper != null) {
        mHelper.handleRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

OkHttpUtil

一个强大的Okhttp的工具类，参考Async-Http、Retrofit2、okhttp3源码通信库写出的Okhttp工具类。主要解决小项目中的http请求，避免与Rxjava、Retrofit耦合小才大用的问题。经测试性能比Rxjava+retrofit+okhttp内存上开销上少一半左右。

OkHttpUtil.post(ctx, HttpConfig.SENDMSGTOPHONE_URL, json.toString(), new OkHttpUtil.SimpleResponseHandler() {
            @Override
            public void onSuccess(Call call, Response response) {
                Log.e("sendMsgToPhone onSuccess","current Thread: " + Thread.currentThread().getName());

            }

            @Override
            public void onFailer(Exception e) {
                Log.e("sendMsgToPhone onFailer","current Thread: " + Thread.currentThread().getName());
            }
        });

HttpUtil

一个简易 AsyncHttp 库的工具类。代码有一定参考性。（该库目前以落后，非主流，无维护）

HttpUtil.post(ctx, HttpConfig.SENDMSGTOPHONE_URL, json.toString(), new OkHttpUtil.SimpleResponseHandler() {
            @Override
            public void onSuccess(Call call, Response response) {
                Log.e("sendMsgToPhone onSuccess","current Thread: " + Thread.currentThread().getName());

            }

            @Override
            public void onFailer(Exception e) {
                Log.e("sendMsgToPhone onFailer","current Thread: " + Thread.currentThread().getName());
            }
        });

HttpClientUtils

一个简易根据android自带HttpURLConnection库的工具类。代码有一定参考性。

    HttpClientUtils.post(url, map, new HttpClientUtils.SimpleResponseCallback() {
        @Override
        public void onSuccess(String response) {
            Log.i(TAG," onSuccess response : " + response);
        }

        @Override
        public void onFailure(Exception error) {
            Log.i(TAG," onFailure error : " + error.getMessage());
        }
    });

CrashHandler

一个app崩溃日志收集类，把App崩溃日志写入SD卡中。

Use: in application onCreate方法中执行以下方法

CrashHandler.getInstance.init(this);

PreferenceUtils

一个简洁易用的SharedPreference工具类。

PreferenceUtils.setPrefString(MainActivity.this,"key","values");

AlipayUtil

支付宝支付工具类

User:

AlipayUtil.instance().pay(context,json,payListener);

Lunar

公历转农历工具类

Lunar lunar = new Lunar(calendar);    

String lunarStr = "";    
lunarStr=lunar.animalsYear()+"年(";    
lunarStr +=lunar.cyclical()+"年)";    
lunarStr +=lunar.toString();    
tvMsg3.setText(lunarStr);    

Lunar lunar = new Lunar(calendar); String lunarStr = ""; lunarStr=lunar.animalsYear()+"年("; lunarStr +=lunar.cyclical()+"年)"; lunarStr +=lunar.toString(); tvMsg3.setText(lunarStr);

XmlUtils

xml文件读取、写入工具类

public static String readLocalXmlConfig(String path) {
        String token = "";
        final File file = new File(path);
        if (file.exists()) {
            try {
                FileInputStream fis = new FileInputStream(file);
                XmlPullParser parser = Xml.newPullParser();
                parser.setInput(fis, "UTF-8");
                int eventType = parser.getEventType();
                while (eventType != XmlPullParser.END_DOCUMENT) {
                    switch (eventType) {
                        case XmlPullParser.START_DOCUMENT:
                            break;
                        case XmlPullParser.START_TAG:
                            String tagName = parser.getName();
                            if (tagName.equals("token")) {
                                token = parser.nextText();
                                Logger.i(TAG, "readLocalXmlConfig 读取成功, token : " + token);
                            }
                            break;
                    }
                    eventType = parser.next();
                }
                fis.close();
            } catch (Exception e) {
                Logger.e(TAG, "readLocalXmlConfig 读取失败 ", e);
            }
        }
        return token;
    }

xml键值对：

   <?xml version = "1.0" encoding="UTF-8"?>
  <switch>
      <config key = "name" value="946396450" />
      <config key = "age" value="946396469" />
      <config key = "sex" value="946396728" />
  </switch>

读取xml键值对代码：

        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        //将字节输入流解析为Document对象
        Document document = builder.parse(context.getAssets().open(xmlFileName));
        //取得文档的根节点元素及其内容,即:<languages>内容</languages>
        Element root = document.getDocumentElement();
        //根据标签名取得相应的元素节点及其内容，由于标签可能不止一个，返回一个节点列表对象
        NodeList nodeList = root.getElementsByTagName("config");
        int confNum = nodeList.getLength();
        confMap = new HashMap<String, String>();
        for (int i = 0; i < confNum; i++) {
            Element ele = (Element) nodeList.item(i);
            if (!ele.getAttribute("key").equals("")) {
                confMap.put(ele.getAttribute("key"),
                        ele.getAttribute("value"));
            }
            Log.i(TAG," key : " + ele.getAttribute("key") +" , value : " + ele.getAttribute("value"));
        }
    } catch (Exception e) {
        System.out.println("init topon.xml failure!");
    }

ImageDownLoader

手写的三级缓存的图片加载框架，适用于图片不多、代码耦合度低的sdk场景，简单快捷，无需多余框架代码及可做到，简单好用，且支持回调和异步操作

  //常规调用
  ImageDownLoader.getInstance(getActivity()).load(imageView,data.getAC_Url());
  
  //支持回调的使用
  ImageDownLoader.getInstance(context).load(imageView, data.getUrl(), new ImageDownLoader.OnLoadImageListener() {
            @Override
            public void onSuccess() {
               
            }

            @Override
            public void onFailed() {

            }
        });

Android之网络图片加载并实现线程切换一套解决方案：

public static void getImageBitmap(Context context,final ImageView imageView, final String url) {
    final Handler handler = new Handler(context.getMainLooper()){
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            Bitmap bit = (Bitmap) msg.obj;
            if(bit != null)
                imageView.setImageBitmap(bit);
        }
    };
    Executors.newSingleThreadExecutor().execute(new Runnable() {
        @Override
        public void run() {
            URL imgUrl = null;
            Bitmap bitmap = null;
            try {
                imgUrl = new URL(url);
                HttpURLConnection conn = (HttpURLConnection) imgUrl
                        .openConnection();
                conn.setDoInput(true);
                conn.connect();
                InputStream is = conn.getInputStream();
                bitmap = BitmapFactory.decodeStream(is);
                is.close();
                handler.sendMessage(handler.obtainMessage(0,bitmap));
            } catch (MalformedURLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    });
}

           public class HookApplication extends Application {

               @Override
               public void onCreate() {
                   super.onCreate();
                   try {
                       HookStartActivityUtil  hookStartActivityUtil = new HookStartActivityUtil(this,ProxyActivity.class);
                       hookStartActivityUtil.hookStartActivity();
                       hookStartActivityUtil.hookLaunchActivity();
                   } catch (Exception e) {
                       e.printStackTrace();
                   }
               }
           }
