Android 日志库 Logger的简单使用

时间：2021-02-12 19:49:59

本文参考自：感谢 Android 开源日志库 Logger 使用教程


这个Logger的使用极其简单，要使用Logger需要添加的依赖库如下

dependencies {
    compile 'com.orhanobut:logger:1.15'
}

我们之所以用Logger工具就是为了能方便的统一管理日志，最起码的要求是测试阶段开启输出日志，上线时不输出日志，这个我们可以在application中做统一的设置，代码如下

/**
 * 自定义Application
 */
public class App extends Application{

final static String MY_TAG = "LoggerTest";
    @Override
    public void onCreate() {
super.onCreate();
        Logger.init(MY_TAG)//自定义日志TAG
                .logLevel(LogLevel.FULL);//测试阶段设置日志输出
//                .logLevel(LogLevel.NONE);//产品上线设置日志不输出
    }
}
这样设置以后当然还需要把自定义的application配置在xml配置文件中

现在可以开始使用了，很简单，直接贴示例代码：

//以下为Logger的适用之法
Logger.i("我是Logger.i输出", 0);
Logger.e("我是Logger.e输出", 0);
Logger.d("我是Logger.d输出");
String XML_CONTENT = "<china dn=\"nay\"><city quName=\"黑龙江\" pyName=\"heilongjiang\" " +
"cityname=\"哈尔滨\" state1=\"1\" state2=\"1\" stateDetailed=\"多云\"/><city quName=\"吉林\"" +
" pyName=\"jilin\" " +
"cityname=\"长春\" state1=\"0\" state2=\"0\" stateDetailed=\"晴\"/><city quName=\"辽宁\" " +
"pyName=\"liaoning\" " +
"cityname=\"沈阳\" state1=\"1\" state2=\"0\" stateDetailed=\"多云转晴\"/><city " +
"quName=\"海南\" pyName=\"hainan\" " +
"cityname=\"海口\" state1=\"22\" state2=\"21\" stateDetailed=\"中到大雨转小到中雨\"/></china>";
//输出上面的xml格式的数据
Logger.xml(XML_CONTENT);
String JSON_CONTENT = "{\"weatherinfo\":{\"city\":\"北京\",\"cityid\":\"101010100\"," +
"\"temp\":\"18\",\"WD\":\"东南风\",\"WS\":\"1级\",\"SD\":\"17%\",\"WSE\":\"1\"," +
"\"time\":\"17:05\",\"isRadar\":\"1\",\"Radar\":\"JC_RADAR_AZ9010_JB\"," +
"\"njd\":\"暂无实况\",\"qy\":\"1011\",\"rain\":\"0\"}}";
//输出上面的json格式的数据
Logger.json(JSON_CONTENT);
List<String> strList = new ArrayList<>();
strList.add("list 1");
strList.add("list 2");
strList.add("list 3");
//输出上面List数据
Logger.d(strList);
Map<String, String> map = new HashMap<>();
map.put("key_hello", "hello");
map.put("key_world", "world");
//输出上面Map数据
Logger.d(map);
//字符串格式化
Logger.d("hello %s %d", "world", 5);
//使用t()设置临时Log名，临时的 TAG 名被追加到自定义 TAG 的后面了
Logger.t("MyTag").d("hello world");

int[] num = new int[3];
try {
    num[4] = 5;
} catch (Exception e){
    Logger.e(e,"错误信息");
}


效果请看下面，按顺序比对输出结果
