Android Log 工具类，用于打印代码位置javaimport android.text.TextUtils;import android.util.Log;

/** * Created by shen on 2016/2/28. */public class LogUtil { public static String tagPrefix=; public static boolean showV=true;

public static void v(String msg) { if (showV) { Log.v(tagPrefix, msg); } }

public static void d(String msg) { Log.d(tagPrefix, msg); }

public static void i(String msg) { Log.i(tagPrefix, msg); }

public static void w(String msg) { Log.w(tagPrefix, msg); }

public static void e(String msg) { Log.e(tagPrefix, msg); }}

Android Log 工具类，可打印出所在代码位置
