首先确定测试版本Log与打包版本Log
自定义LogUtil 通过DeBugMode控制是否输出Log
在需要加Log的地方使用LogUtil中的方法
import android.content.Context; import android.util.Log; import android.widget.Toast; public class LogUtil { public static final String TAG = "log"; public static void log(String tag, String msg, boolean isDebug, int type) { if (isDebug) { switch (type) { case Log.VERBOSE: Log.v(tag, msg); break; case Log.DEBUG: Log.d(tag, msg); break; case Log.INFO: Log.i(tag, msg); break; case Log.WARN: Log.w(tag, msg); break; case Log.ERROR: Log.e(tag, msg); break; default: Log.v(tag, msg); break; } } } public static void log(String tag, String msg, int type) { log(tag, msg, Constant.DebugMode, type); } public static void log(String tag, String msg) { log(tag, msg, Constant.DebugMode, Log.VERBOSE); } public static void e(String tag, String msg) { log(tag, msg, Constant.DebugMode, Log.ERROR); } public static void i(String tag, String msg) { log(tag, msg, Constant.DebugMode, Log.INFO); } public static void w(String tag, String msg) { log(tag, msg, Constant.DebugMode, Log.WARN); } public static void v(String tag, String msg) { log(tag, msg, Constant.DebugMode, Log.VERBOSE); } public static void d(String tag, String msg) { log(tag, msg, Constant.DebugMode, Log.DEBUG); } public static void log(String msg) { log(TAG, msg, Constant.DebugMode, Log.VERBOSE); } public static void xn(String msg) { log("xn", msg, Constant.DebugMode, Log.DEBUG); } /** * 显示toast * * @param context * @param text * @param duration */ public static void show(Context context, String text, int duration) { if (context == null || StrUtil.isEmpty(text)) { log(TAG, "loggerUtil show args is invalid!!!", Log.ERROR); return; } if (duration >= 3000) { duration = Toast.LENGTH_LONG; } else { duration = Toast.LENGTH_SHORT; } Toast.makeText(context, text, duration).show(); } public static void show(Context context, String text) { show(context, text, 0); } public static void showNetError(Context context) { if (context == null) { log(TAG, "showNetError context is null!!!", Log.ERROR); return; } try { show(context, "网络不好"); } catch (Exception e) { e.printStackTrace(); log(TAG, "showNetError toast error!!!", Log.ERROR); } } public static void System(String content) { if (Constant.DebugMode) { System.out.println(content); } } }
